Hi   !

That screenshot somehow failed to upload .....

But : would you please do this :

3-bar menu => Options => Add-ons

and see if there's an add-on, called  : Tab Groups 2.1.4

If so : would you please disable it and see if that makes a difference  ?

Hey :-) Yes ... Tab Groups 2.1.4 is there. Has been for decades and I have about 10 different groups each with multiple tabs. I can only assume disabling is going to kill all of them?

Saved screenshot in different format and re-uploaded.

Thank you for the screenshots   !

The reason why I asked about that add-on is in this thread :

I sure hope that solves the problem for you as well   !

Thanks ... I will have a look at that thread and try and follow whats going on. Just hope I don't lose all my groups and tabs!!

Would you also take a look at the last post here :

Thank you Happy112 ... you are right on the money. Disabling Tab Groups resolves the issue ... unfortunately all the Groups seem to disappear so I now need to find a new solution before I finally disable this :-)

This issue with the Tab Groups extension seems to only affect users on Mac.

It could probably be fixed with some code in userChrome.css to set some margin to the Tab bar.

You can also try an extension like Classic Theme Restorer to place the Tab bar on bottom to see if this still happens.

Thanks Cor-el ... appreciate the suggestion. Looks like that extn goes eol Nov this year like Tab Groups. The search for a replacement for Tab Groups begins ... or its migrate to Chrome.

Would you please report this to the developer of the add-on  ? And tell him that this is being posted (not only by you, but by others as well) on a public support forum   -   that just might urge him to fix this as fast as he can  !
