It's really a good option for the lack of a better one... It gets the job done by hiding tabs from other "workspaces" into the hidden tabs list. Didn't notice a lot of bugs.
But a few things that really push me to use other browsers: it's not as elegant, very simple design, doesn't feel native and natural (compared to vivaldi, arc, zen, opera, etc); and two very annoying things: tab groups don't hidden, but are kinda empty, but still show previews, which brakes immersion and the fact that it spawns a directory every single day in your home folder ("STG-..."), and never cleans it up.

My favorite browser extension, hands down. Yes, the last Firefox update broke it. Need your tabs back? Settings > Backup Your Simple Tab Groups > Enable Auto-backup (you should be doing this anyway). Then Restore Backup every time you relaunch Firefox. (I delete existing data and revert to my last save.)

That's how I'm managing until the maintainer updates this extension. (Based on their location in Ukraine, I'm willing to give them some slack.)

update it to the latest version of firefox,
now!!! 😤

I don't know why anyone would use this. Does not reliably save tab groups.

keeps crashing when trying to restore backup. tab groups load but not the pages in them.

It's okay. But your max is going to be 4 groups before tabs/browser starts to feel laggy on MacOS.

Одного чудового дня пропали усі вкладинки, не рекомендую нікому у кого є до праці 10+ вкладинок

К сожалению, дополнение неисправно. При попытке восстановить группы из резервной копии, браузер просто падает и восстанавливаются пустые группы.

Simplesmente NÃO funciona. Gastei mais de 3h criando grupos, mas a extensão SINGLE TAB GROUPS simplesmente não grava os grupos que criei e os apaga sempre.

Nope, great Idea but every some updates it kills everything and is not relaible. Now lost 200 tabs ....

All open tabs that were not in a group suddenly disappeared, as I was managing groups. They only reappeared again when the extension was uninstalled. That's a terrible user experience. Avoid.

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.

One of the most confusing interfaces, and most unpredictable interactions of any add-on I've used to date.

I created 4 tab groups -- social media & news; payments & banking; messaging; shopping cart. I populated each with several url's that I go to frequently. I created each group in a separate window and then selected the set of tabs and created the group. So far so good.

The next day I come back, I'm on tab in my shopping cart group which I had open and then select the group social media, which I had closed the evening before. It opens in the shopping cart group. Worse, it empties out my social media group, which is now for some reason associated with the shopping cart. So I have to recreate the group on new window and remove them from the shopping cart. Why? I have no idea.

Worse, if I try to move the tabs from my shopping cart by putting them in my original social media group, it tells me the shopping cart group is closed. Why? I have no idea.

This add-on seems so simple, yet, none of the features makes sense in its implementation. This could be a great add-on if it had any consistency. I'm still using it, but every day I have to reset one or more of my tab groups, scratching my head each time.

Consistency. This is not...

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.

Lost everything. Don't use.

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!
