Having numerous tabs open in your browser can be a great way to store a plethora of information, but can just as easily become a problem. Too many open tabs can be confusing to navigate, eat up resources, or get in the way of your actual work.

But what can you do about it? There are many solutions to this issue, whether it be controlling how you open those tabs or just how you look at them.

So, here are six of the best Firefox extensions to help you manage your tabs.

1. Auto Tab Discard

The first entry on this list is Auto Tab Discard, a Firefox extension which aims to reduce memory load and increase browser speed. It does this in several ways.

Primarily, the extension works by “discarding” tabs. In truth, this is less like discarding and more like pausing or freezing the tab. It will remain in the tab bar, just like the rest of what you’re currently working with. But, after Auto Tab Discard discards a tab, it will no longer use resources in the background.

This is excellent for freeing up memory and space for Firefox to do other things. You can adjust when and how you want to discard these tabs effortlessly as well.

You can whitelist certain websites if you never want to discard them, and on the flip side you can allocate certain hostnames that the extension will always automatically discard.

Auto Tab Discard also comes with the option to customize when it will or will not discard a tab. You might wish to omit tabs that are playing a media source from being eligible or to only have the extension run when you’re using your laptop’s battery, for instance.

2. OneTab

If the problem you’re having isn’t with processing power, but rather with organization, then OneTab might just be able to help you out.

OneTab is a Firefox extension which will add a simple button to the end of your search bar. When you click on this button, OneTab will convert all of your currently open tabs into a list. You can then open these tabs one by one or restore them all in one go.

This extension has the benefit of also being able to cut down on memory load and so consequently increase browsing speeds. It will, however, lose information about the tabs that you have saved, such as your browsing position or partially filled data fields.

3. Tree Style Tab

If you’re looking for an entirely new way to organize your tabs, then consider giving Tree Style Tab a try. Tree Style Tab is a Firefox extension which aims to completely reorganize the way that you look at tabs while still leaving the default view available to you.

The extension does this by adding a brand-new sub-menu to your browser, which you can access by clicking on the extension icon or through a keyboard shortcut.

This new sub-menu contains all the tabs you have currently opened but is organized in a tree instead of the usual layout. For some of you, this might take a while to get used to, but at its core it’s a simple enough idea to understand.

Every tab you open begins at the top of each tree, and every new tab opened from that webpage will appear as a child of that one. Effectively, this allows you to easily see where each tab originated from, which allows you to more easily keep all of your tabs organized.

4. New Tab Override

Next on this list comes New Tab Override. New Tab Override is a Firefox extension which does just about exactly what you would expect. It allows you to override Firefox’s regular new tab page.

This extension lets you set the new tab page to just about anything you might want. You can set it to whatever website you like or to your current home page, and even lets you store a local HTML file in the extension for use as your new tab page.

You can also customize where you will open new tabs to, set the focus to the address bar or to the website itself, and even have the address bar automatically add “http://” if it’s missing from a URL.

Tab Session Manager is a Firefox extension which allows you to save and restore the state of various windows and tabs within your browser. At its core, this means that you can set up different browsing templates for you to jump between.

6. Undo Close Tab

It’s easy to make mistakes when browsing, but that’s no reason you can’t correct those mistakes. Undo Close Tab is an extension for Firefox which alleviates one of the most common problems that you might face when browsing: accidentally closing tabs.

Be Careful Around Extensions

There are a wide variety of extensions and add-ons which you can add to Firefox or any other browser to help improve your browsing experience, and hopefully, you’ve found a wide variety of them through this article.

However, not all extensions are equal, and not all extensions are good for you or your browser. Information you can trust is paramount, and it always pays to be critical of what you download or install on your computer.
