Cumbersome to use. Not intuitive. I thought maybe I could take a few open tabs out of several and group them. Sure, but now the rest of the tabs are gone unless I also group them. Essentially if you want to group, you have to group everything into groups or you're accessing your non-grouped tabs through a little dropdown. If that's not the case, it wasn't intuitive enough to figure out otherwise or would be efficient to use.

The idea is nice, but I feel misled. It said it "works like chrome's" but the one in chrome collapses and opens with a simple click. I feel like once I have a tab in a group I better not hope I can access it ever again. Clicking on the link just make the page refresh. Again, not cool to claim it's "like chromes" when it really isn't

Put all my tabs into a group, restarted firefox, the group no longer exists.

STAY AWAY IF YOU WANT TO KEEP YOUR TABS!!!

I did not install this extension because once I saw how much data it collected and what it wanted access to, I was quick not to allow it. Why does it need access to recently closed tabs, access to download files, read all website data? C'mon... this was one of the only tab grouping extensions I would have use too...

Private mode is NOT SUPPORTED. What a bummer!

The absolute worst thing happened to me! I tried to open an old tab in a group I that's never been opened for months, I checked Task Manager and Firefox went from 5gb memory usage to over 20gb and it just kept increasing until my PC stops responding. This memory bs happened everytime I try to open Firefox, so I had to uninstall Firefox and lost everything.

Nothing 'simple' about this add-on. Confusing and over-engineered. Name change is needed...;)

A major drawback of this addon is that it forces you to hide the tabs that are grouped - as far as I'm concerned, this is not really tab grouping, it's more like a "fancy" bookmark sorter, only less functional and more annoying. I couldn't find a way around this problem yet. This is a disadvantage compared to the Chrome tab grouping - where your group appears as a single tab that can be easily expanded and collapsed when you want to show/hide all the tabs belonging to this group.

I think the UI needs serious work for this to be a usable tool. It also needs to work properly across multiple firefox windows. I did the mistake of installing this while having multiple tabs on 2 windows and it was not a fun experience.

Spesso le schede dentro un gruppo si duplicano/triplicano senza motivo

Addon popped up a page stating it crashed or something or other and requested me to load a backup. Doing so made me lose countless windows and tabs that just so happened to not belong to any group at the time

Omg do NOT use this extension. I really do not understand why it has so many starts. Needlessly complex as another reviewer has stated. I grouped some tabs, then opened that group and it cleared my entire window of the tabs I was using! Unbelievable. Who in their right mind thought that was a good idea? I had to disable the extension to get them back. Stay far, far away from this extension if you value your tabs!

Was great till it started to load so slowly that it took over my browser completely for 10+ minutes.

This was a great extension until it started saving browser sessions for no apparent reason. I understand this might be a feature some appreciate but when I close my browser I want it to be fresh when it is reopened. At the very least there should be the option to disable this feature. And no, I do not have Firefox setting "Open previous windows and tabs" enabled. This behavior only happens while this add-on is enabled.

Great add-on, but a Bug is really anoying me since late 2021. If I close & reopen the browser, every tab in groups with "always open tab in specific container" option activated is duplicated (see here: https://github.com/Drive4ik/simple-tab-groups/issues/891 ). The issue is open since Dec, 2nd and the developer didn't answered (we are in February...). Update: going from 2 to 1 star to see if the developer only cares about 1 star reviews....
