This is a super helpful extension!
There is one thing that could be improved. It would be great if the native Firefox groups remained related to the tab group. When I switch groups using Simple Tab Groups, the Firefox groups disappear along with the tabs. It's like having tabs and groups within groups.

Exactly what I have been looking for. I love that you can have multiple groups that share the same container. I use it to separate school subjects, but I want every school subject to be in the school container. I also like the automatic tab unloading feature that saves ram.

Have been using this addon for years. I currently have 1480 tabs across 28 groups (yes, I need to clean that up), but somehow this addon has not yet failed me. I do make occasional backups just in case. Great if going through sites with chapters/episodes that if saved via bookmark would become outdated. The management interface is easy to use, too.

I love this addon and have been using it for years. It's very useful for a kleptomaniac power user like me who keeps hundreds of tabs and needs a way to sort them. STG has its own backup function as well, which has saved me a few times when Firefox bugs and fails to retain its state. I also get the impression STG helps avoid Firefox getting overwhelmed and degrading performance.

My only issue is that it currently has no compatibility with the new native Firefox tab group function, which prevents STG backups from saving Firefox groups. Hoping that comes in a future update!

Best of the best app for saving work at current state as-is and moving to other work to find it in a state as it was. I'm convinced that 'simple' in addon name is eqivalent to 'good'

Perfect to organize all your tabs

Very easy way to decrease the number of open tabs.

Simply the best tab manager these days. Have used it since release without issues.

Recently Firefox added its own tab grouping feature that could synergize really well with this extension, but unfortunately there's a bug:
When you create a Firefox group it also creates group collapse button for it, and when you switch to another STG group, it hides the grouped tabs but not that collapse button.
Hope it gets patched, because it's a bit janky and annoying.
