Diễn đàn hỗ trợ Firefox

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.

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?

Regarding the new tab grouping feature, I see you have to go to "about.config" and change "browser.tabs.groups.enabled" to "TRUE" to activate this feature. But there are 3 other options - what do each of these other 3 mean?

(1) browser.tabs.groups.smart.enabled (2) browser.tabs.groups.smart.optin (3) browser.tabs.groups.smart.userEnabled

Thanks.

I am still unable to create Tab Groups. I've followed the instructions on the update but it doesn't work. I'm using the latest version of Firefox with the latest version of Mac OS.

TIA
