    Gee, look at all the add-ons, or extensions, that are no longer available since Quantum came along! And the "geniuses" at Mozilla wonder why Firefox's market share keeps falling. Here's a hint: the only reason I still use Firefox is because I REFUSE to "upgrade" to Quantum. I'm sticking with version 56.0.2, which still allows my add-ons to run.

    Of course, Mozilla seems determined to destroy even that. A number of my favorite add-ons (Fireshot, Multiple Bookmarks Toolbar, RIP, among them) have mysteriously vanished, and I can't get them back, or they don't run properly anymore. Meanwhile, the folks at Pale Moon are slowly adding them to that browser (which also seems able to access the Comments features of several websites that Firefox no longer can - such as WBUR).

    Keep it up Mozilla, and one day I'll just switch to Pale Moon permanently, and you'll achieve what appears to be your goal: your market share will consist ONLY OF THE PEOPLE WORKING AT MOZILLA!

    Thank God you haven't screwed up Thunderbird. (Yet.)

      Note: Remember, if you read the comments, the article is a rewrite of a rewrite of a rewrite, so the information is dated. A number of add-ons will never work with the new architecture of FF and requirements. Take it with a grain of salt.

      So we are reading information from 2014, not 2017. And, if one were to run all of these add-ons, FF wouldn't even budge from a homepage.

      MUO is notorious for rewrites of old articles and failing to mention the many new add-ons that replace some of the old ones mentioned.

        Modern FF is crap. I finally updated and can't even open my fav 22 youtube channels at once without FF freezing while pages loaded, while my older one (16) didn't have any issues with freezing and the pages loaded quickly enough for me to view without issue., still took some time yes but not anywhere near as long as new FF.
        Also while these addons are 'old' and as such will not work, FF had REMOVED the ability for any modern versions of similar addons to even BE created at all, with the same functionality.

        Old FF == for the user, new FF == for the corporate drones.

      Palemoon is based on an old Firefox codebase, and many addons think it's Firefox 27! The best Mozilla-based browser was Cyberfox x64, but the developer has quit for health reasons, so I've switched to Waterfox, which gets updated a day or two after the main Firefox.

      • likefunbutnot
        June 28, 2017 at 9:50 pm

        Waterfox is essentially just copying Mozilla code and trying to maintain XUL at this point. While that's better than what Mozilla itself is doing, I'm happier with the Palemoon decision to fork from the decidedly less stupid pre-27 Firefox codebase, including the pre-27 Firefox UI. Palemoon is at this point its own distinct browser, one where I can get the full degree of customization, security and privacy features I want without having to deal with the ongoing stupidity of Mozilla's fresh new ways to turn its browser in to yet another clone of Chrome.

        As for the question of Waterfox vs. Palemoon, I found that Palemoon uses less RAM per tab and has fewer problems with add-ons being invalidated by updates. I'm not having to fiddle with the UI or remove unwanted features. Waterfox just isn't bringing anything to the table as far as I can tell.

    [Tab Management]
    There is also TabDeque which is wonderful.
    Simply click on the current tab to "minimize" it and get back to the last tab you were coming from, and so on.
    Nice to get back on your tab switching historical track.

    I would suggest FireGesture ( or any good mouse gesture add-on. It completely changed the way I browse. But be careful, mouse gestures are addictive and once you start using them you'll be trying to use them in every program, not just in FireFox!

    Also, Session Manager ( which integrates well with TabMixPlus (which is also essential).

    FEBE Has A Feature I Use The Most:

    - The Individual .XPI File Save Of All The Extensions You Have Already Installed.

    I Would Love To Have That Feature For Some Or All Of The CHROME Clones.

    Thank You.

    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.

    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?

      Wouldn't right clicking on the page you want to save and then from the drop down menu select "save page to "or "save page as" work in the situation of full page downloads work ?
      I am sure there are other ways to go about this in the newest version of Firefox , but all versions should have this as an option.

    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.

      I Agree, "Tab Mix Plus" is an excellent tab management tool.

      I also have been using ever since I learned about it, which was approximately 10 minutes after using internet explorer .

      Of course this change did not happen until I wasted a year on AOL and finding new ways to get free months of time from them ..... and one day I woke up and found out that the internet isn't just AOL and can be gotten in much better way like Comcast, a decision I'm starting to think might get tossed into the AOL pile if a better provider comes to my area.

      Unfortunately for me they are the fastest and best provider I've got ATM !!!!

    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.

      "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.

      There are many who have FREE informational sites who do not sell anything. The only way these sites are able to exist is through showing ads. It is not ethical for people to use those sites with an ad-blocker on.

        "The only way these sites are able to exist is through showing ads. "
        If their content is so crappy that they have to rely on ads, then maybe they no business existing. There is no God-given or Constitutionally guaranteed right for any business to exist, Under capitalism, if you follow the wrong business plan, you are gone. Relying on ads is the wrong business plan. Porno sites and political sites are not complaining about ad-blockers but they have interesting content.

        " It is not ethical for people to use those sites with an ad-blocker on."
        But it is ethical for those sites to steal my bandwidth with ads for products I will never even look at? I am the one paying for bandwidth, not the sites that object to my use of ad-blockers.

    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!

    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)

    Great post Justin! But I would add 4 to this list:
    - "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) => [NO LONGER AVAILABLE]

      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).

    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

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

      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!
