This has a lot of potential to become the best tab grouping addon for Firefox. Design should be more elegant in Dark Mode as well. Thanks to the developer, you did a great job!

I don't understand how anyone could use FF without this add-on. Very easy to understand and does exactly what one would expect it to.

FF crashed and I lost all my tabs + groups the other day. After an hour or so of messing around with .json/.jsonlz4 files, I concluded that FF had just lost them. I'm glad that I had made a backup from STG, it's unfortunate that it's wayy back from 6 months ago.
Could an auto-backup feature be added? I don't trust FF with my tabs anymore.

If you manage to do the "free arrangment" in "Manage groups" you will get 5 stars and 6 if FF supports it one day :D
Why do we have to add [STG plugin] Open Manage groups to open it directly?

Use the channel updates ESR (last68.4.1). Add-on not work: "downloading. please wait" Reinstall add-on, restore pref - working))

Works like a charm and is very snappy. Thanks for all the effort!

Thanks for giving me back my sanity.

Endlich kein Reload mehr der Tabs sobald man von einer Gruppe in die andere wechselt. Aus diesem Grund habe ich FF bisher noch nicht geupdated. Jetzt kann ich endlich.

Just tried it again and lost all my tabs after an hour!

Edit after 3 years: tried it again. Result is the same. Though I have backup now

Just what I've been waiting for, ever since tab groups were removed from firefox!

I have no doubt that there will be some "bumps in the road", as there always is for something on the bleeding edge, but I jumped in at version 3.1.2, with FF6.2, and I've not had any problems at all, thus far.

I stuck with the ESR until a couple of days ago, when even its latest version (finally) became incompatible with the legacy Tab Groups addon (may it "rest in peace"). That's when I discovererd STG, and decided to "move back" to the mainstream FF release, and see whether STG would get me close to where I wanted to be, as compared to the original.

I am EXTREMELY happy with STG. There is obviously a tremendous amount of work behind it, and it really shows. I could NOT be happier at this point, with the result. THANKS for taking on this development effort, and "saving" all of us who felt like Tab Groups was one of "life's necessities". STG is a worthy successor.

With Firefox updated to v62 and addon to v3.1.1 it doesn't works. Tabs from one groups are shifted to others when change, and according to extensions like Copy All Tabs or All Tabs Helper, discarded tabs remanin loaded, showing rigth now more than 100, despite the current group has only 3.

Thanks for bringing tab grouping to the new Firefox.

Thanks to the developer for the speedy reply to my bug. Keyboard shortcuts are working again and I have upped this to 5 stars.

Now that tab hiding has been implemented, this add-on does what I need it to do: hide tabs in other groups and let me switch between groups with keyboard shortcuts.

Very useful expansion. Works as announced. However, does not seem to integrate with the "Sync open tabs" feature of Firefox Sync.

If you're having performance problems or high memory consumption, disable tab thumbnails generation.

Wow, this is brilliant and why have I not found this before. It's so simple to use and does exactly what it says.

Compared to the old Tab Groups, I really love the concise group selection pulldown UI. I can use Simple Tab Groups' visual mode to manage tabs as needed, but don't need that elaborate UI when I'm just navigating between groups.

I'm at 3.499
I think it's a fabulous bit of code - potentially really useful. Problem is that it's not being integrated with other, more essential add-ons or features.
For me, the deal killer is the lack of coordination with ONETAB, which is one of my primary ways of keeping track of my research in a simple permanent list system. With Simple Tab all nice and neat - now I run OneTab and it's like I just powered up a chain saw at a society event.
The kicker to giving Simple Tab the boot, is the fact that multiple windows know not to let OneTab bother it. Obviously a similar feature, so perhaps I will find some way of managing those windows visually? Why didn't Simple Tab Groups think of that, instead of re-inventing the bowling alley?

great features, closest to old Tab Groups FF feature, but (currently) a huge memory hog... like, HUGE.
