The recent update to Firefox 57 marked my favourite Tab Groups extension obsolete; the Firefox Multi-Account Containers extension it offers is nowhere near adequate - this apparent beta can't even move tabs between groups. (On the positive side, the new rendering engine fixes performance issues added two releases ago.) I'm trying to rig up a temporary solution in a hope they will do something about this one too eventually.

What I currently settled on is the Tree Style Tab extension combined with a set of silly local pages of the following form used as group roots:

<!DOCTYPE html>
<title>Group Name</title>

However, I can't find a way to protect them from accidental closing. Tried pinning them, but a pinned tab cannot have children. Even worse, a closed parent tab also closes its children with no way to restore them all at once. Any suggestions?

The workaround I chose is to use Firefox ESR (Extended Support Release). This release is based on Firefox 52 and will be supported until June 26 2018. Hopefully then a useable replacement for Tab Groups will have emerged and stabilized.

  • Thank you very much for your answer. I'm aware of Firefox ESR. The issue with it is that the now-obsolete versions of add-ons it runs, including Adblock, NoScript and other essential ones, are not likely to get timely updates, nor are website, antivirus, etc. developers going to take the obsolete versions of both browser and add-ons into account. The whole thing is going to become unfit for everyday use long before June - that was exactly the reason I dropped my beloved old Opera.
