Rated 5 out of 5 stars

At any point during my browsing, I'll have upwards of 80 tabs open. Although I hibernate my tabs, the RAM FX uses still exceeds 600 MB; after having the browser open for awhile, its RAM usage approaches 1 GB and my system generally locks up because I've run out of RAM and I don't want to wait for the paging to stop. Even with SSDs configured as RAID-0, the thrashing is still intolerable and .

I finally found this add-on and it does what I need it to do, which is (duh) group my tabs. I realize this add-on is still very young and has a way to go before it's mature, but I want to offer a couple of suggestions. I'm sure the authors have thought of these and have plans to implement them, but a little nudge never hurts. ;-)

1. Moving tabs between groups is kind of kludgey right now with having to use the addon's context menu entries. I'd like to be able to drag and drop tabs to and from both the browser's tab bar and from other tab groups.

2. Also, sometimes it might be preferable to have the same tab in two groups, so enabling <ctrl> as an accelerator key would be great.

3. After accumulating a number of tab groups, I could see where it would help a user to have color-coded tabs, so tabs could be recognized faster.

4. Additionally, being able to add favicons to each of Tab Group Bar's tabs would help improve the speed of tab group recognition, too.

5. I second moen's suggestion of being able to arrange tab groups, too, preferably via drag & drop.

This review is for a previous version of the add-on (1.2.1-signed.1-signed). 

Point 2 is not possible. Tab Groups are a Firefox feature, this add-on is just a more convenient way of accessing it. The rest are already on my todo list.

Hiding the tabs in groups does nothing to help with memory. You want the Suspend Tab and MemoryFox add-ons for that.
