Rated 3 out of 5 stars

Fantastic addon but badly out dated/buggy and apparently the author does not have time for this. Also begs for a rewrite to take advantage of the built-in tab groups. Using TabGroups Menu as alternative which is faster and reliable. However, no tab group bar. :(

I'm glad to see this addon updated. I like the new features etc. but i think this has come at the cost of stability. Weird errors and some locked in tabs etc. Hopefully these will get ironed out eventually.

In any case the new version is heading the right direction. Keep up the good work!

I've been running TabGroups Manager with other addons like TMP, Session Manager, BarTab and about 30 other active addons.

In month or two i've been keeping the same set of tabs between sessions and currently running at 1500 tabs, inside 30 or so groups. So far i've seen only couple occasions where the tabs didn't stay inside their group after restoring session. Also with this many groups, it's starting to get bit tedious to manage them and more tabs you get slower the startup time is. Even with 1500 tabs, when using BarTab, it takes omly about 10-15 seconds to sort all tabs into their groups.

Overall this addon plays nice with other addons i've used so far and it is quite stable. Recommend this to any "tab maniacs" out there. :)

After some months of heavy use of this tabgroups, with other 41 active addons, there has been very few problems so far.

Occasionally (very rare), after session is restored, one or two groups there is tabs that are completely unresponsive e.g. clicking them does not do anything etc. Restart usually seems to fix this.

Also i've yet to discover how to control what page is opened when new group is created with the default single tab open. For awhile it was my "fast dial" addons page (weird), now it's blank. I've got TabMixPlus set to load new tabs to homepage but it does not seem to work with this(?).

Overall, this addon plays nicely with other addons, as i already mentioned, i've got "few" other addons installed on my current profile.

I'll give it 4 stars, maybe i'm too picky but theres some room for improvement. In any case, THANKS!

Something ive wanted for long time... Rated 4 out of 5 stars

Works extremely well. Only wish i could rearrange the groups etc.

As to how well this behaves with other extensions. TabMixPlus sessions didnt work well, but using Session Manager instead works nicely. Also TMP multiple rows does not work but theres a workaround using custom Stylish "style".

Make sure you follow the TabBar option change (Scrollable without buttons) as instructed in the style page.

Thank you for the invaluable suggestion.

Thank you for the invaluable suggestion.
It was confirmed that the multi-rows tab was possible by this Style Sheet.
And, I confirmed that it can apply this Style Sheet by TabGroupsManager without "Stylish".
It is an almost ideal method because it can correspond neatly even if the Group is switched.
The only problem is that the width of the tab is always minimized.
When the Multi-row tab of "Tab Mix Plus" cannot be used well, I will achieve it by this method.
However, even if this method will be used, it takes time for a while.

The next version can rearrange of the Group by Drag & Drop.
In addition, even if Firefox is ended, the order of the Group can be preserved.

It is difficult to deal with the session manager of "Tab Mix Plus" because SessionStore of Firefox is used more in the next version.
