Utilise depuis plusieurs année sans soucis. Toutefois depuis v5.1 l'affichage du conflit avec "tab session manager" est très pénible (quelque fois deux fenêtres à fermer) un pop up aurait peut être suffit.

Excellent extension; essential for anyone that gets easily overwhelmed and/or likes to separate their tabs by topic or workflow.

I tried numerous suggestions but could not even get this to work so uninstalling

Great for organization, but not fully compatible with multi-account containers and sometimes is glichy.

Not the type of groups feature that chrome has, still leaves the tab bar messy and crowded.

I thought I could use it to organize hundreds of opened tabs. Not only did it it fail to do that, it also irrevertebly closed all tabs when I was trying something out. That sucks hard!

Allows to organize hundreds of tabs.

As far as I can see, this is just a glorified bookmarks tool (which we already have). Why bother to install an add on for something we already have? I hope someone designs a tab groups tool like the one in Chrome.

I've installed the add-on just yesterday and already enjoy having a tab group per project instead of an unsorted pile of tabs. It works really good so far.

Just one problem I had: when I created the first group and switched into it, I was unable to find a way to go back to the ungrouped tabs. Is there even any? I think there should be an explanation in the readme.

I'm glad there was a simple solution: the app offered to move the tabs into the current or a new group, so I just put the ungrouped ones in a group called "Default" for now.

Simply The Best tab management feature

At start firefox this addon often not started correctly. I need manualy disable and enable it for work.
But if not see on this bug - addon is very nice.

Upon clicking a tab group it opened a new window and closed the old, deleting all open tabs without a warning or a chance to restore them.

Then suddenly the created group was empty too.

Really unprofessional and annoying. Just stick to established UI-norms, what's so hard?
Drive4ik can't be voted down enough.

4.8.1 version. Activation used 15MB RAM (only RAM, not total memory.) Full page tab group manager is only presented in bright white. -- even though I followed the instruction for setting svg.context-properties.content.enabled . User browser configuration has no effect. Group management tab shows as constantly loading.

Extremely useful add-on and well implemented features, such as treating certain windows as a group, and even switching to them if there's already a window with that group opened, makes multiple workflows extremely easy to implement!
