Enable Multiple Tabs Selection in Mozilla Firefox

Many popular web browsers allow selecting and moving multiple tabs at once. You can use this feature in Google Chrome, Opera, and Vivaldi. However, Firefox users are out of luck. But here is a bit of good news - the team behind Firefox is working on adding the same feature to the browser. Interested users can already give it a try.

Modern versions of Firefox are  built with the new Quantum engine. They come with a refined user interface, codenamed "Photon". The browser now comes without support for XUL-based add-ons, so all of the classic add-ons are deprecated and incompatible. See

Thanks to the changes made to the engine and the UI, the browser is blazingly fast. The user interface of the app is more responsive and it also starts up noticeably faster. The engine renders web pages much faster than it ever did in the Gecko era.

As of the writing, the ability to select and move multiple tabs has already landed to the Nightly version of Firefox. So, if you want to check it out, download and install Nightly. Then, refer to the following article:

Run different Firefox versions simultaneously

To enable multiple tabs selection in Mozilla Firefox, do the following.

1. Open a new tab and enter the following text in the address bar:

   about:config

   Confirm that you will be careful if a warning message appears for you.

2. Enter the following text in the search box: browser.tabs.multiselect.
3. This preference is enabled out of the box for select users. If its value is false in your case, double-click it to enable the feature (set it to true).
4. The feature is now enabled.

Try Tab Multiselect in action in Mozilla Firefox

1. Press and hold the CTRL key on the keyboard.
2. Left-click on the tab you want to select.
3. Do not release the CTRL key, then click on the next tab you want to select. You will have two tabs selected.
4. To select a range of tabs in Google Chrome, click on the first tab you want to select.
5. Now, click on the last tab in the range you want to select.
6. The tabs are selected now.

You can drag-n-drop the selected tabs to a new location on the tab bar. They will be moved all at once.

Right-click on any of them to see the available commands. They can be applied to all the selected tabs.

Again, at the time of this writing, the feature is still a work-in-progress and may be unstable. Mozilla is still polishing it.
