The Best Firefox Addons

Ads by Google

Firefox is famous for its addons, and for good reason: they can make your browser do just about anything. But which addons are the most useful? Here are the addons we think are best, what they do, and where you can find them.

Enjoy! Also let us know if we’ve missed anything, okay? We plan to update the list semi-regularly.

Bookmarks and Clipping

If you’re using the web for reserach, you need to compile what you find as quickly as possible, and note a few sites for future reference. Here are tools for saving those relevent bits of information, and for compiling and managing your bookmarks.

Evernote Web Clipper

If you don’t use Evernote, you’re missing out: it’s the perfect place to put all those things you need to remember for later but don’t need right now. And the fastest way to send something to Evernote is the Web Clipper, which Aaron called the ultimate content saving tool. You won’t remember how you browsed without it.


Creating citations is the funnest part of academic writing, right? If you’re convinced, check out Zotero for Firefox. It takes the stress out of referencing by creating a bibliography in just one click, and it’s also a useful tool for compiling resources. A must for academics.


If you’d rather your clippings live right in your browser, check out Scrapbook. You’ll get a sidebar where you can store and share research.

Ads by Google


If you use more than one browser, you need this. XMarks is a bookmark and password syncing service compatible with Firefox, Chrome, Safari and Internet Explorer – meaning you can take your bookmarks with you when you switch from one to the other.


Compile things you find interesting, arrange them visually and share the results with the world. That’s the idea behind Pearl Trees, which lets you share the best of the web with your own visual library. It’s long been a top-rated Firefox addon, check it out and learn why.

QuickFox Notes

Sometimes, while researching, you need to quickly write something down. If you’d rather keep everything in the browser, QuickFox notes lets you write and save notes with a tabbed interface.

Custom Browsing

Firefox isn’t just a tool you can use: it’s something you can make personal, and use to make the web look however you like. Here are some addons that let you do just that, by changing how you browser behaves or adding quick tools to the right-click menu.


There are a lot of Firefox themes out there, but if you can’t find one that’s just right, don’t worry: you can design your own Firefox skin with Stratiform. It’s easy.

All-In-One Sidebar

Bookmarks, history, downloads: why should all of these things live in a tiny toolbar? Give yourself more room to work, without adding clutter: put everything you need in a sidebar.

Vertical Toolbar

Don’t want an entire sidebar? Just move a few buttons, then. Doing so can save you a lot of vertical space, so give it a shot if you want more of your screen to show the site you’re looking at.


Do you never use the search bar? Save yourself some space, without losing any functionality: combine search with the address bar just like Chrome does. You can even assign keywords to different search engines, letting you use any of them without moving your hands from the keyboard.

Add To Search Bar

Are there sites you search regularly? This tool lets you do that easily. With Add To Search Bar installed you can right-click any search bar, on any site, to add it to your Search Toolbar’s drop-down list of options.

Download Statusbar

Watch the progress of your downloads as you browse the web. Download Statusbar lets you replace the Firefox downloads window with a toolbar at the bottom of your screen. Perfect if you don’t like the download button or window offered by Firefox.


See some text you don’t understand? With this addon installed all you need to do is right-click to see a translation.


Where did that picture come from? TinEye lets you find out quickly: just right-click, then click “Search image on TinEye” to find images similar from around the web. There’s no end of uses for this sort of reverse image search, from spotting fake Facebook profile pictures to determining whether an image is fair use.


Don’t like the way in-page searches (CTL+F) work in Firefox? FindBar lets you move your searches to the top, and lets you customize everything. Resize the bar, change how highlighted results look, and a lot more.

All-In-One Gestures

Move your mouse in a particular way to trigger an action. Whether you want to go “back” by quickly moving your mouse to the left or to open your bookmarks by drawing a “b”, this plugin has you covered.


You know that bar that used to be at the bottom of the browser? You can bring it back with this addon (or put the things that used to be there somewhere else).


Customize the way your favourite websites look with scripts. This addon is legendary, though possibly less useful with the decay and eventual death of GreasyFork is probably the best place to find scripts now.


Similar to Greasemonkey in some ways, but focused on changing how sites look instead of how they act. Think of it as themes for your favourite sites.

User Agent Switcher

Want to see the mobile version of a page? Or access a site that’s “Chrome Only”, or “Internet Explorer Only”? User agent lets you trick websites into thinking you’re using a different browser.

Evernote Clearly

It’s hard to focus when a site is cluttered with ads, sidebars and other distractions. Clearly removes the clutter from webpages, so you can do some reading. You can also send what you’re reading to Evernote for future reference.


If you’re an aspiring web developer, you need to know about these tools – they’re the reason so many pros use Firefox, or at least keep it around for certain instances.


If you’re a developer, you’re already using it. If you’re just curious, know that it’s a way you can customize any website by editing the CSS, HTML and Javascript in real time. Watch what happens and learn!


You probably don’t have every color code memorized, so use while you’re editing sites with Firebug. It pops up and lets you pick a colour with your mouse, and pastes the proper code.

Web Developer

Adds a toolbar jam-packed with tools developers rely on to test and tweak their sites.


Why install a separate program for FTP transfers when you can do it right in your browser? FireFTP is a powerful Firefox FTP client.


An eyedropper that can identify any color on any website, so you can copy the color code and use it in another program. A must for designers.


It’s like a tape measure for web designers, letting you quickly measure the size in pixels of any area. Perfect if you need to know how big an image you can fit in a given place.


Hey, which font is that? Find out quickly with this tool.

Connect To Mobile

Firefox syncs your bookmarks and open tabs with its mobile version, but you can send a lot more than that to your phone. Here are tools for getting content from your desktop Firefox to you other devices.

Send To Kindle

Found a long article, but don’t have time to read it now? With this you can save websites to your Kindle, so you can read them later on your e-ink screen.


Send the currently open article to the ultimate digital bookmarking service, so you can read it later on your phone or tablet.


Nothing is worse than typing a long password with a phone keyboard. With LastPass for Firefox, you can sync your passwords to your phone and all of your other devices. LastPass also makes logging into sites faster on your desktop, so it’s the ideal password management system.


Use your computer’s comfortable keyboard to send text messages, thanks to this Firefox addon. You’ll need to install the MightyText app on your Android phone to use this.

Music and Video

There’s a lot of great media online, and Firefox is a good browser to enjoy it with. But are there tools that can make streaming, and downloading, a bit better? Of course there are.


If you like to find and download media – images, videos or music – you’re going to want this legendary addon. One click lets you download every piece of media linked to on a page, or every image on that page.

Ant Video Downloader

Downloads videos from a surprising number of sites, so you can watch them offline. Use responsibly.

Hola Unblocker

Wish you could watch American streaming site like Hulu, or British ones like iPlayer? Hola lets you easily access geoflitered content.

Turn Off The Lights

Darkens everything on the page but the video you’re watching, kind of like turning the lights off in the theatre.


HTTPS everywhere

Lots of sites offer HTTPS encryption, but leave it off by default. This addon turns it on whenever possible, giving you an added layer of security.

Web Of Trust

Is the site you’re looking at trustworthy? Users vote about the trustworthiness of a site, meaning you’ll get a warning if you’re browsing something potentially harmful. It’s your own personal Internet bodyguard.


Don’t want Google watching your every move? This addon sends a bunch of random searches to Google, Bing and more, making it harder to search engines to track your online actvity.

Shopping Enhancers

Finding the best price is way easier in your browser than it is at the mall, but that doesn’t mean it couldn’t be even easier. Here are the best Firefox tools for the job.

Invisible Hand

It’s automated price comparison! Browse any online store, and this addon will let you know if anything you’re looking at can be found for less somewhere else. This will save you money.

Automatically see coupon codes in your search results, and get fast price comparisons as well.

Amazon Add To Wish List

Add anything you find online to your Amazon Wish List – regardless of which site you found it on.

Social Networking Tools

Social networks are great for keeping in touch with friends and finding great content. Here are a few tools that make your favourite networks just a bit better.


The magic Internet button that takes you to a random website. Still awesome after all these years.


Learn more about the people you’re emailing. This addon integrates with Gmail, appearing in the sidebar, and gives you career details and social network links for whoever you’re emailing right now. Start conversations and connect with your contacts.


Make fancy email sigantures for Gmail and Yahoo Mail, pointing out your latest blog post and even adding social media links.

Reddit Enhancement Suite

Add keyboard shortcuts, embedded media and so much more to Reddit. If you browse the site often, this is a must-have. It’s necessary if you want to use Reddit like a boss.


Tweeting too much can overwhelm your followers. With Buffer, you can schedule to share whatever you’re reading right now sometime later – important if you want to optimize viewership.

FB Purity

Facebook shows you a lot of information you don’t care about – here’s your chance to filter that out. You can pick which of Facebooks features you care about, and to only see those things. Control what you see in your news feed.

Tab Management

If you regularly can’t see the favicons because of how many tabs you have open, there’s help for you. Here are some addons that can keep things under control.

Tab Utilities

If there’s anything – anything at all – you wish you could change about the way tabs behave in Firefox, check this addon first.

Duplicate Tab Closer

If you open the same website in two different tabs, this addon will automatically close one of them, helping you organize your tabs.

Tab Badge

Add notifications to your tabs, so you can do things like track your unread emails at a glance.

Tile Tabs

Browse multiple sites, at once, in a single window. This addon lets you get more out of your wide screen.

I stopped reading after Omnibar and Add to Search Bar.

These features are built into Firefox, no add-on required. Your posts are worthless.

Ayham Alkasir

you’re dead wrong ! I’m a ff user since beta. never been a built-ins. (adding to search bar is limited ONLY to SOME websites that allows this initially).
and about Omnibar I guess you didn’t read just looked at the images.
In addition to the wrong info, being offensive is something nobody like to read here. thanks and goodbye!


Mahdi you are wrong.
Maybe you can link us to your superduper informative website?


Scrapbook X is better than Scrapbook.



Dus You check these addons….?
Rapportive is dead because LinkedIn took it over. LinkedIn killed it. Sadly.

I dont think Statiform works well with the newest Firefox. Classic Theme Restorer is the newest best!



That’s a lot of plugins. Thanks, Justin!



Great list!
Don’t mind those that are rude by saying your posts are worthless :)



“…fancy email sigantures…” Whoops. Spell check and proofreading are your friends.


Hildy J

Two other things QuickFox does:

1) you can encrypt any note with its own password
2) it stores notes as bookmarks so if you sync bookmarks, you sync the notes


Jerome Masson

Great post Justin! But I would add 4 to this list:
– “AdBlock Edge” combined with “Element Hiding Helper” (the first one removes all the ads for a hassle-free web browsing, the second helps you hide elements you don’t want to see either like feedback button or social sharing toolbars). => +
– “Disconnect” (great addition to AdBlock Edge) =>
– Lazarus: Form Recovery (as the name implies, you can recover any form you typed with a right-click after you close/refresh a webpage or even after your browser crashed) =>

I also second the comment about Classic Theme Restorer =>

Alexis C

It’s good for us but not for MUO. They make a living of this by displaying us.


Lazarus is, for all intents and purposes, dead–I’m sad to say that, as it was a long-standing favorite of mine. I switched to Form History Control last month, which is working well for me so far (though it’s a bit more powerful, and consequently more complicated, than Lazarus).



You don’t need ColorZilla anymore. Firefox has this built into the browser in the dev button on the toolbar (you might need to enable it first)


Christopher Wetmore

I’d go with SocialFixer rather than FB Purity, if for no other reason than habit. And frequent updates.



I am really impressed by this list as a long-time Firefox user.
Quite a lot of them is already installed to my firefox, but I found more useful addons from this list!

You did a really great job, and this list is very helpful to me :)
Thank you for sharing, Justin! Keep up the good work!



More add-ons to slow down Firefox.

BTW – Where are AdBlockPlus and NoScript?

Oh, that’s right! They supposedly destroy the Internet. They have been around for years and the Internet is doing better than ever.

Jerry Cooper

Do you just go to every tech blog and rant all day long?? Seems you hardly ever have anything nice to say. Sad.


“Do you just go to every tech blog and rant all day long??”
Do you follow me around the Internet so you can say with certainty that I rant on every tech blog? Or are you just generalizing based on one post?

“Seems you hardly ever have anything nice to say.”
Let’s analyze my comments. Every so often MUO publishes an article with a title like “The X Best add-ons for NAME browser. Since I’ve been reading MUO, various authors have recommended a total of somewhere around 50 add-ons. When MUO recommends something, readers, especially those with less PC experience, start using the recommended add-on or product. It has been my experience that many people download and use all the “convenience” and “appearance” add-ons they can find in the name of customization. Then they complain that their browser is slow. Unfortunately, the more add-ons you have running, the slower your browser becomes. IIRC, in the past year MUO had a poll on how many add-ons people use. If I am not mistaken, the most common number was around 100 add-ons, with a number of users having more than 300 add-ons. Hence my comment.

BTW – I made no comment about the quality of the suggested add-ons. Mozilla/Firefox vet their add-ons pretty well so that bad ones are few and far between.
At least five of MUO’s regular writers, at one time or another, have written anti-AdBlock articles saying , in so many words, that ad blocking software “is destroying the Internet.” Other MUO writers have expressed the same sentiment while responding to user posts. MUO writers aciduously avoid ever mentioning AdBlock and NoScript, except in a negative manner. Hence my comment.



You rat bastard! Just when I thought I had every ad on I need for my browser, you give me a list of some really cool ones to try! Great article btw.

Justin Pot

Sorry about that! :)


Steve M.

Surprised “Tab Mix Plus” wasn’t in your list. I’ve been using it since it launched. awesome tabs enhancement add-on! adds about a hundred more things you can do with/to/in/etc… tabs.


Omar G.

Ugh… Where’s PushBullet?



There used to be a great image down loader, but it was changed to VIDEO LOADER Ultimate and I can not get it to work.
And the old “Downloadhelper” disappeared from the add-ons.
This site seems to not mention even ONE to download pictures or images from a web page using Firefox add-ons.
ANYONE found a good and reliable image or picture down-loader that can download the entire page?



Was hoping to see SiteLauncher on the list, – it’s a speed dial extension but better, because it offers keyboard shortcuts and overlays the current page, so faster than opening a new tab first.
