Diễn đàn hỗ trợ Firefox

With the progressive rollout of tab groups having ended (I am assuming that because they are available by default in fresh installations), I would expect them to be available when I sync with my Firefox profile. However, when I sign in to the browser to sync all my settings, the option disappears. I am more interested in why the rollout never reached me than being told to enable tab groups in `about:options`. The profile switcher is also not showing up, but I am not sure if that is still in beta.

The article at https://support.mozilla.org/en-US/kb/tab-groups says (and shows a mockup animation) to drag a tab onto another tab to create a tab group. It also says the feature is being rolled out in v137 and will be available to all users by May 6.

It's May 8, and I'm using v138, but dragging a tab onto another tab just reorders the tabs.

What's the deal?

When the new Firefox version offered Tab Groups, I was enthusiastic. I have a huge number of open tabs reflecting all aspects of my life. What a disappointment to find now that all those individual tabs are still sitting there on the tab bar, just grouped. I need to COLLAPSE those groups, at least until I hover over or right-click the group icon. What a bother.

Just started using Waterfox on MacBook.

When I use <Command><Tab> to switch back to the application, although the icon does appear on far-left on the display of application icons, indicating it is the foreground application, the application does not appear in front of the other applications as is usual MacBook behaviour.
