Where are the Firefox tab groups? Firefox browser cancel tab page Group features

Some good features are not necessarily accepted by the user, and developers will have to simply remove these features. Now the Firefox browser's tab Group feature will also be removed.

The Firefox go Faster program is a project from Mozilla that plans to remove features that are not used by many people. The first to be removed is "tab group" and "full theme".

The Firefox director of Engineering, Dave Camp, says the tab group is designed to help users manage a large number of tags experimentally, but not many users choose to use them, and their popularity is disproportionately proportional to the amount of effort being put into maintenance.

In fact, there are many features, such as "tab Group" and "complete theme", that are not very many people use and consume energy to maintain, and are gradually removed from the plan.

So later users in the use of the new version of Firefox Firefox browser is unable to use the tab page group function.
