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".

Looks great and works well. Thank you!

It does what I was looking for!

Dear Drive4ik - when you gonna fix the bug - ??? it keeps on giving same "Tab error" still :(

Tiene todo lo mejor de su predecesor además de funcionalidades nuevas y es muy rapido.

I love this extension; Groups are one of the most important features and you've implemented them beautifully. However, I have a question (and forgive me if this is the wrong place to ask, but I couldn't find anyplace else).

Are all my groups in memory all the time? Or only the active group? That's important for resource management.

Thanks!

This is the best that ever came after Firefox killed the integrated TabGroup feature. Just wondering if there could be the option to set a shortcut key for backuping your tab goups to a json file?

Just amazing. Simply amazing. It moves my "Personal" tabs automatically to group.
There are few small things that can help like sync and hiding (instead reloading when switch)(And this is coming in next FF version so it will be implemented in new version of addon)

Thank you for reviving this add-on!! Works GREAT, almost better than the old original. Just one request: I'm losing my tab groups after I shut down FF. I thought that did not happen before, but not sure. Would it be possible to add an autosave / auto backup / auto start option?

But above all: thank you guys for the excellent work in making Firefox great again.

It's the closest thing to the original Tab Groups that I've yet seen.
Pluses: CLEAN and neat interface. Great Layout idea. Easy to shuffle things around by Drag and Drop.

Very awesome! Brings back one of my favorite features that was removed from Firefox.

Very promising Tab Groups successor.
Edit:
After 3 years this had become one of the most irreplaceable must-have extensions for me, and I have to commend the developer for still maintaining it. I'm still baffled why such useful functionality (Panorama) was removed from FF in the first place.

FINALLY A PLUGIN REALLY THAT WORKS!!! As a web developer, I have like a million tabs open at the same time and this feature is a MUST HAVE to allow me to group tabs! (I started grouping tabs before Firefox added the feature, so I move to firefox feature, then they removed it and I started using a plugin but It stopped working .. was missing this feature untill now)
