It would be great except that it keeps all your tabs open between sessions even if you set firefox to open a fresh session. If not for this I would give five stars. As is it is unusable.

As someone who has ADHD and keeps hundreds of tabs open at all times, thank you. This addon saves so much time and I love how I can cycle through the groups with hotkeys.

Moves to another group when opening the first tab in the group in the container.

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.

I love this addon and use it every day. It is a better version of the removed tab groups feature in firefox.

This addon not only does the job well, but also is amazingly polished, with lots of customization options and no bugs. It's a great piece of software, huge thanks for your efforts author(s). <3

As someone who has a bad habit of always having a lot of tabs open this was godsend. I have been using it for months and it works flawlessly.

I've been looking for an addon like this for a long time. Simplifies my workflow incredibly and can now relax rather than alt tab multiple windows to oblivion.

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....

I previously gave this 1-star because it would get stuck loading, but it turned out to be a Firefox issue - not an issue with the extension! 5-stars now, best Tab Groups extension for FF!

If your monitor refresh rate is high (and on new MBPs that's true) you need to adjust the layout.frame_rate config variable in about:config to equal your monitor's refresh rate. Crazy, huh? For new MBP's, that's 120.

This is the best Tab Groups extension hands down. I tried them all. This is it.

not user friendly, overly complex if trying to fill the speed dial hole
