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

works very good

This is my favorite extension. It makes Firefox the best web browser!

ive been using this addon for about a year now, it crashes every once in a while and i have to restore backups that i usually manually create. it worked everytime so i didnt think anything about it really. this time it crashed and when i use the backup it wont load my tabs on the top. i just lost about 6 months of research and other things. way to go asshats. dont use this piece of shit or you will regret it eventually.

Can't backup where I want bruh

works great untill you open another window.

Sadly it quite often drops all of my tabs and I need to manually add them back in. As far as the design goes, it's quite nice. When it works, it's useful. It's not as intuitive as the group tabs in Chrome, but that's a problem I have with Mozilla, not this extension. However, not being able to change the location of backups is really grating on me.

Installed the plugin, had over 50+ tabs open, created a new group and all my tabs were gone, thanks for absolutely nothing and ruining my day

Making my experience very convenience. Easy 5 star
