Not a big fan of this. I live and die by my tab groups, so when Firefox did away with them, I needed a replacement, so I downloaded this. After using it for about a week, I dont like it and am looking for a replacement. Why? There are numerous problems with it. Where do I start?
It forgets what pages you had loaded in some tabs
It duplicates not just tabs, but entire groups of tabs
If in tab manager, you delete one tab, it takes you to the top of that group of tabs immediately

But the biggest problem I have with it is this: every time you open the browser or switch between tab groups, it insists on loading every single tab in that groups. Did I mention when I first opened my browser with this installed it put all my tabs from all groups into one group? Yeah, it does that. So I had about 160 tabs and it insisted on loading every one of those pages all at the same time. I've been working to cut back and separate tabs into groups, but I still have maybe 75 tabs in the largest group, and I don't see any improvement in performance. I recommend downloading it because Firefox has screwed us over and this is the only game in town as far as a solution. But before you install it, I recommend minimizing the number of tabs as much as possible.

Wow, this add-on just keeps getting better. I just noticed the new "Manage Tabs" screen where you can re-arrange and edit the different groups.

You have to understand that the "Hide Tabs" option is not the authors fault and someday perhaps mozilla will wake up and accept that API.

The only thing I miss is the ability to import and export my groups

brilliant productivity enhancer, best replacement for tab groups that's available now.
I'd love it if
- the colours were a little more muted,
- I could edit a group name from the initial drop down menu,
- it was quicker to delete the auto created groups on new window - it's noisy, and deleting them is quite a few clicks
(delete + undo would be better than delete and confirm, delete from initial popdown would be a click saver)

otherwise, awesome.

Спасибо!
как глоток свежего воздуха )

Better and better!
thanks

Would be five stars if it wouldn't load every tab at once when switching groups. It kinda lags my PC

This is the best replacement for the original TabGroups extension from Firefox <57. Works very well considering the current restrictions of the Firefox API. I'm looking forward to the day when Firefox allows this extension to hide tabs instad of closing them.

I can not believe that this is the replacement for the old Tab Groups??? I just tried to restore 139 tabs and lost everyone of them. If I had just seen the restore session tab before I tried to use this extension: I would have been fine. I am NOT at all - in no way at all - liking this new Firefox except that it is faster. Yes it most definately is but Most of the fun using Firefox was the addons and extensions. That - by the way - used to work pretty darn well. Now there are Other extensions or Might we Say - No Extensions!

Great extension, lighter and easier than Group tabs.
Is there an option to export tab groups & settings?
Another nice feature would be to be able to reorder groups in pop up window.

Thank you for doing this! It's awesome!! One cool feature would be to have an option to not load all tabs when you change group. That should increase the performance a LOT!

EDIT: The regular expression feature is incredible. Pure sugar for power users.

This extension works well at a brief glance. You can quickly group & sort your tabs and start switching contexts.

Some caveats:
- When loading a group all tabs load at once instead of just the focused tab. It would be nice if the unfocused tabs appeared but did not load, similar to when Firefox loads tabs from last time on start. I suspect this is a limitation in the current WE APIs.
- if there is a tab you want open all the time, you'll have to pin it.

I am happy to finally get back overview of my tabs! :-)

Thank you so much!!

But I'm facing a little problem, unlike the provided screenshots, the extension menu fills some unnecessary space when just 2 groups are in the list as seen in this screenshot: prntscr . com / hmwwxz

Would be great if you could fix it :)

Works great! Thank you! Even like it more than old tab groups!

Great jobs !

I had a shitload of tabs, that was the idea to get something like the old tab groups. I just started sorting out, and wanted to check the new group. When I changed back, it started to load all of my tabs, filling the memory. It wasn't fun.

Neat and convenient, a good alternative for legacy Tab Groups.
