The 8 Best Firefox Extensions for Managing Tabs

1. Auto Tab Discard

This addon allows you to automatically unload tabs from memory without closing them. As soon as you switch to one of them, its content will be reloaded.

The extension is very useful if you have a lot of websites open in the background all the time on a low-powered device. With Auto Tab Discard they won't devour anymore RAM.

Those sites that you always need can be added to the whitelist, and the extension will not touch them.

2. OneTab

Another extension to save RAM and space on the browser panel. Just a necessary tool for everyone who has dozens and even hundreds of sites open at the same time.

Click on the OneTab button and it will close all the tabs in the Firefox window, moving them to a list on a separate page. They can be saved for later or published on the Internet to share links with colleagues.

3. Tab Stash

The Tab Stash extension works in a similar way to OneTab, but it moves closed sites not to its own memory, but to browser bookmarks. This means that you can instantly close tabs on one computer and continue working with them on another device, and even open them in mobile Firefox. No third party registrations required.

In addition, the extension can import and export sites and bookmarks as rich text, Markdown and OneTab. Tabs can be saved in the sidebar and sorted into groups so you can switch between sets of sites as needed.

4. Tree Style Tab

Most browsers have problem: When there are too many tabs, their labels no longer fit on the horizontal line at the top. It becomes impossible to understand open sites just by looking at them.

Tree Style Tab overcomes this difficulty. It arranges tabs in a vertical bar on the side of the browser so that site names remain readable even when you have hundreds of addresses open. In addition, the addon sorts the sites in a tree structure to make them easier to navigate.

5. Tab Session Manager

An advanced tool for saving groups of tabs as so-called sessions. Let's say you've uploaded Google Docs, Trello, Stack Overflow, and Todoist to the Work group. Now, to open your work sites, you do not need to open new tabs and type addresses. Just click on the "Work" session in the Tab Session Manager - and the necessary services will open at the same time. Very saves time.

In addition to manually created sets of sites, Tab Session Manager can automatically save opened tabs in the background and synchronize them between your devices. With this extension, you can turn off your work computer at the office, come home, open your laptop and continue browsing the same sites.

6. Undo Close Tab

This addon is as simple as possible: it allows you to instantly restore the tab you accidentally closed, that's all. You might say, but Firefox already knows how to return them. Yes, but for this you need to click "Menu" → "History" → "Recently closed tabs" and select the site with the mouse. It's long. And Undo Close Tab restores tabs in one click.

7. New Tab Override

By default, Firefox allows you to open either your home page or a blank screen in a new tab. You cannot assign an arbitrary URL.

New Tab Override might fix that. The extension is able to launch any services and sites that you specify when opening tabs. Useful if you want your new tabs to display, say, the start page of Google or Yandex by default.

8. Firefox Multi-Account Containers

When you use the same browser account both at home and in the office, it’s a little annoying if, in the midst of a workflow, personal tabs and addresses flicker in front of you. It's tritely distracting, not to mention a violation privacy.

Firefox Multi-Account Containers is an official extension from Mozilla that helps you keep work, play, school and other areas of your life separate. It contains several pre-installed "containers": "Personal", "Work", "Banking" and "Purchases". In addition, you can create as many new categories as you like.

When you add sites to the "container", Firefox marks the tabs with different color labels. You can make, say, Google Docs always open in the "Work" section, and Steam - in the "Games". For each group of sites, you can use a separate Firefox Sync account so that bookmarks and search history from different "containers" do not get mixed up.

The extension allows you to send all unnecessary addresses and services to a separate window with one click, and then close or minimize it. This way, important data won't get mixed up with entertainment, the browser bar will look tidier, and you'll be less likely to be distracted by putting things in order.
