[Tip] Enable / Disable Multiple Tabs Selection Feature in Mozilla Firefox

Today in this tutorial, we are going to share a small tip which will help you in activating and enabling a hidden secret feature in Mozilla Firefox which is not enabled by default. This hidden secret feature is called “Multiple Tabs Selection“. We told you about this feature a few months back in our exclusive Nightly Updates topic (check out UPDATE 120).

In Mozilla Firefox web browser, you can’t select multiple tabs. Other web browsers such as Google Chrome allow users to select multiple tabs and perform actions on the selected tabs such as pin tabs, close tabs, mute tabs, etc.

If you follow the method given in this tutorial, you’ll be able to select multiple tabs at once in Mozilla Firefox web browser and then select operations on the set of selected tabs. At the moment only one single operation/action is supported i.e. close selected tabs. But in future more operations will be added such as bookmark selected tabs, reload/refresh selected tabs, pin selected tabs, mute selected tabs, etc.
