5 stars for the superb effort in getting this add-on up to par with the old Tab Groups (and surpassing it in some ways)! Must have been a huge challenge with FFQ, I can imagine. I use tab groups every day for work to help keep everything organized. Don't know what I'd do without it. Keep up the great work!

The best!

Thank you, I looking for add-on like this

It makes the life of a Web developer a lot more productive.

Can't wait to see what future improvements will bring us. :-)

Wow, finally on FF Quantum (FF61, 07/2018): we have old good Tab Groups and even better and more customizable. I like custom icons for groups - very handy. Thanks, developer! <3

Finally, a fully functional replacement for the good old TabGroups!

After the last release, the tabs are finally not reloaded after switching groups. Taking into account the limitations of the new API, this extension deserves 6 stars.

Thanks Drive4ik! Now I can use Firefox just like I used to before WebExtensions era.

Just seen the permissions for this plugin... Wow! Access your data for all websites // Store unlimited amount of client-side data... That means you'll know as much about me as my own family! What you going to do with all that?

TO Drive4ik: Ok I'll take your word for it. Putting back 5 stars

Finally a working Tab Group solution, hide tab API is a real panacea
Only caveat is that tab management itself is a tab

Finally the group tab feature is back more than never with the hide-tabs API \o/

This is a life saving addon, no doubt. Finally a usable one.

very nice

was looking for this add-on for a long time, works as described, good job

Love the new version with tab hiding!

Still one of the best Addons and one of the reasons I still use Firefox!

Thanks to the dev that he understands the needs of the users and keeps the core functionality like it is.

I see that some people give one star because this doesn't work as a library (only open tabs are kept in groups). Please keep it this way!

Thank you!

Great work! I've been missing the old Tab Groups so much and this extension is the perfect substitute. Thank you very much!

Calling it Simple is a bit of misnomer; it's more feature complete than the 'Panorama View' add-ons. Speaking of which has the "free range" aspect that this add-on desires. So with the new update, it acts as a good replacement for like the original "Tab Groups", it's not a perfect 1:1 but that's alright. The issue of tabs loading all at once, or closing are a thing of the past. I've switched back to this and look forward to future developments.

Consider adding Dark theme and DuckDuckGo icon proxy service (example: https://icons.duckduckgo.com/ip2/youtube.com.ico). I'd rather use that over Google s2.

Great to have tab groups back with this extension. Now that the tab hiding API is available and used it's fantastic. Thanks for the excellent work on it!

I was waiting for this update, now the extension is very good! Thank you!

Nice legacy Tab Groups replacement on quantum! Most of hotkeys for switching groups can almost recover the legacy one except those limitation in extensions (That's no choice). Good to see this release just before legacy Firefox ESR end of support. Thanks for bringing the final hope and allow for move on quantum seamlessly.

I am looking forward to the free arrange be implemented and that will be fully replace, and/or even enhance of legacy Tab Groups.

Suggestion: Is it possible close the "Manage Groups" tab after switching groups? Otherwise whenever using hotkey to open "Manage Groups", it will switch back to the group with "Manage Groups" tab. The current solution is uncheck 'Open "Manage Groups" in new tab'.

Edit: already in STG 3.0.7, not experimental
Edit 2: Thanks for response. One more suggestion: how about close "Manage Groups" tab when it is inactive OR hide all other tabs when "Manage Groups" is active (so user must choose a group or close it to remain in current group)? This can force the "Manage Groups" tab never belongs to any groups, which prevent group auto switching when opening "Manage Groups".
