Hi Ray, left click should work. When you click the group name, the group contracts, click again to switch it back.

Example screenshot attached.

Thank you jscher2000 I would like to let you know that the link "Probelm solved~" did not work, I always got an error message:

Looks like there’s a problem with this site

https://support.mozilla.org/en-US/questions/1511693/solve/1732530?watch=TMXnzjsCEV&utm_campaign=questions-reply&utm_source=notification&utm_medium=email sent back an error.

Error code: 405 Method Not Allowed

   Check to make sure you’ve typed the web site address correctly.

But I also see another problem (if you want to call it problem ...): I cannot open a new window and open there the "tab groups", because it send me to another window where the same tab group is open. I would have like to be able to have the same tab group on different windows. It is possible? Thank you any way for your help, it is very nice of you. Thank you!

That's fine. You can also try the ... menu to the right of the user name on the post to see whether it is an option there.

Firefox has a feature to duplicate open tabs, but I do not see an option to duplicate a whole tab group as a group. Maybe there is a trick, but otherwise it would need to go onto the feature wish list.

Help shape the future of Tab Groups in Firefox! on Mozilla Connect

Thank you very much!! Bye Ray
