Basically I don't know what I would do without it.

Glad this one continued the now abandoned panorama view, which is honestly my only reason to stay on firefox, and this new design makes it even better, very easy to use and flexable for up to hundreds of tabs, best addon on firefox!

Exactly what I am looking for!!! I always have like 30+ tabs opened!! This solves my problem. I will see if this can also solve my PC memory issue. Just wondering if the extension actively cleans up those tabs that put into background to release memory ?

Absolute must have for switching work/fun context ;)

I was happy for a few months, but two days ago, I lost all my tabs, all of the sudden. I really don't know what happened. The groups are still there and buoyant, but empty.

It took 12 Gb RAM and broke every time

I was searching for something like vivaldi tab groups, this is a life saver, and really well organized, even better than vivaldi tab groups

The single most valuable extension available for Firefox. Running Win-10 Pro with a fast processor and 32 GB RAM means having a bunch of groups with 8-12 tabs each is no problem.

Pass on this one. Made my computer run slow and hot. Not intuitive to use which is how I think other people have lost their bookmarks on it; FYI if you get stuck trying to open a group in order to save all the tabs in it, you need to click on any tab WITHIN the group to open the whole group. (Clicking the group itself only offers to delete it.) Still looking for my perfect tab solution. *wistful sigh*

Perfect for efficient work on multiple projects, helps you keep your environment clean and clutterless. Great to use with Fast Tab Switcher, BTW.

I hope there is a setting option to set not show the number of groups on the icon.
Put all the feature icons on the right side of toolbar. It will be more convenient.
