Najlepsza!

It's quite clunky (the UI needs a lot of work), but this is the only add-on that does what I can find: allow you to swap between entire sets of tabs at once (e.g. different projects or clients; or "personal" and "business", etc.

Great module. For my usage, it works well with more than 50+ tabs opened and more than 20 groups from 2 to 50+ tabs opened inside each group.

Tabs are not too long to open when switching group as I read in others comments.
No problem also with more than one monitor (i use 3 monitors without any problem)

Thanks. It's very useful. You made my day.

CAVEAT: My review isn't based on how the add-on functions - but rather the responsiveness and helpfulness of the add-on author.

I was frustrated, trying to migrate my groups from the Tab Groups add-on (which doesn't work in FF 57) and completely confused by the instructions. I sent a support email(s/he added helpful information to the About section for the extension, two alternatives for those in my position, and even a third option in the email to me.

With such a positive response to my negative email - I'm certain users of this add-on will find the developer equally responsive to questions and suggestions.

Thank you for having updated the plugin in time for FF Quantum!

Can you please add possibility to import tab groups from Tab Groups addon (https://addons.mozilla.org/ru/firefox/addon/tab-groups-panorama)? I want to migrate. Thanks.
