This is a very useful extension. I wouldn't say it's simple, but it is powerful.

It's useful to be able to move tabs into groups based on their URLs; I use this to separate different projects so that I can switch context between them.

It doesn't seem to play well with other extensions that automatically close tabs in the background, though; for example Dustman. After a tab is auto-closed, when I switch to that group, STG says “Invalid tab” and “Background not inited”. After that, STG doesn't work. If I disable and re-enable it, the toolbar button never finishes loading. Restarting Firefox seems to fix it. (I think this may be the same issue as #212 on GitHub.)

Edit 2018-07-20: Thanks, I've updated to 3.0.10. Let's see how it goes!

Edit 2018-07-23: I'm still seeing “Invalid tab” notifications that stop STG from loading the group, but I haven't yet seen a “Background not inited” one, and STG starts working properly again when I reload it from the menu.

Good first pass at this extension. Buggy - frequently, it will freeze up while switching tabs due to duplicate url's in more than one tab group.

Needs some work, but I am grateful that someone came up with a replacement for the old tab groups. It would be very helpful if there was a button to open the grid view directly from the browser GUI, not via the Simple Tab Groups button, i.e. with one click instead of two.

Too many bugs
More bugs since the last updates.. !!!

Many faults in loading groups
It opens the same tabs 3 or 4 times when loading. Much trouble...

Need lot of fixing

Hi,

I have just upgrade to the latest version of this addon.
Is there a way to switch off the hidden tabs feature? I want to see my tabs across the top as in the previous
versions please?
I have multiple tab groups for different tasks
and each group has multiple tabs open
I like this separation of tabs into tasks groups.

I don't want to disable the addon, I want to use the addon but not have the tabs hidden.
Is there a way I as a user can turn on/turn off this hidden tabs feature?

IF I disable teh addon then all my tabs are unhidden but put into one tab group
I don't want this, I want separate tab groups with my tabs visible in each tab group as in previous versions
This must be possible and I just don't know how to set, please tell me how.
Thank you

Thank you, I looking for add-on like this

i just enabled this at version 3.0.8 and it brought back tabs i had closed today.
also it moved some tabs to a hidden menu and when i click the icon, i see this:
"Found hidden unsynchronized tabs. Click on tab to show it into current group/window or:
Move all of this tabs into current group/window
Create new group with all of this tabs
Close all of this tabs"

if i disable it now, i'm worried i'll lose those hidden tabs. this is really not a good design. if i enable this addon, it should not mess around with my tabs and risk losing them. i might disable it now and lose those tabs.
you really need to keep this addon from messing with users' tabs.

and "this tabs" should be corrected to "these tabs"

ok, so i clicked "move all tabs into current group". it's kind of fixed the lost tabs, but now i have some duplicates and the when i had enabled it first, the tabs to the right of the addons tab, moved to the top so they're to the right of my last pinned tab.
please fix all these bugs !

It makes the life of a Web developer a lot more productive.

Can't wait to see what future improvements will bring us. :-)

Wow, finally on FF Quantum (FF61, 07/2018): we have old good Tab Groups and even better and more customizable. I like custom icons for groups - very handy. Thanks, developer! <3

Finally, a fully functional replacement for the good old TabGroups!

After the last release, the tabs are finally not reloaded after switching groups. Taking into account the limitations of the new API, this extension deserves 6 stars.

Thanks Drive4ik! Now I can use Firefox just like I used to before WebExtensions era.

Just seen the permissions for this plugin... Wow! Access your data for all websites // Store unlimited amount of client-side data... That means you'll know as much about me as my own family! What you going to do with all that?

TO Drive4ik: Ok I'll take your word for it. Putting back 5 stars

Finally a working Tab Group solution, hide tab API is a real panacea
Only caveat is that tab management itself is a tab

Finally the group tab feature is back more than never with the hide-tabs API \o/

This is a life saving addon, no doubt. Finally a usable one.

Given the poor state FF API has been in ever since Quantum, this is as good a replacement for Tab Groups as can be expected. There is a rather unfortunate and extremely annoying issue where when you switch to a different group, your current tab moves to the new group, but otherwise it seems to work more or less as well as you could expect. I wish there was an option to close the "group management" tab when you select a tab in it, the way group management worked in tab groups.

very nice

was looking for this add-on for a long time, works as described, good job

Love the new version with tab hiding!

Still one of the best Addons and one of the reasons I still use Firefox!

Thanks to the dev that he understands the needs of the users and keeps the core functionality like it is.

I see that some people give one star because this doesn't work as a library (only open tabs are kept in groups). Please keep it this way!

Thank you!
