Great replacement for removed built-in tab groups! Simple and easy to setup.

I modify my appreciation and give 5 stars insted of 3 because now this module is perfect for me.
Bravo to the author.

I gave this addon the second chance, and it works great! The only feature I miss is exporting/importing specific groups in the addon.

Better than original Tab Groups, best tab manager, works in all modern firefox versions including latest nightly, very well done job, thanks a lot.

Super helpful! I'm one of those people who has over six or seven tabs open all the time, and this makes managing them *so* much better. Thanks!

The best addon. Saves my time. And helps me stay focused.

If you were a die-hard Tab Groups user, this just might be the only way forward for you with FF Quantum.

I tried many replacements for Tab Groups until this add-on came out. In my opinion, it's the only one that even comes close (unless there is a proper re-write of the original Tab Groups for FF Quantum).

There are some bumps along the way - some of them are Firefox bugs, some of them are add-on issues - but I think the developer has been doing a great job of maintaining this add-on and managing expectations.

It's great to be able to group tabs based on what is currently being focused on, and to avoid seeing the noise that is interesting at another time, when you have another focus.
Right now, I want to relax tonight but will probably check things anyway. Actors, facts, etc. But want to leave the planning of the holiday for later. Or things that are interesting for my job.

Happy that someone continues to take care of the add on on the same track. Thanks a lot!

Simple and very useful

A must-have for power users!

It let me upgrade to Quantum. Without extention like old Tab Groups i would switch to Chrome.

This extension has finally allowed me to upgrade to Firefox Quantum. I had Tab Groups extension installed which was not supported on new Firefox at that time and didn't want to make a move without that or similar extension. Simple Tab Groups are just what I needed. Allows to group tabs, to switch groups, doesn't load all tabs in group but only active one (saves RAM).

To all unsatisfied reviewers:
* Tabs loss is not due to this extension, this is an acknowledged Firefox bug. The extension author has shown it happens even without his extension. It is registered in Firefox bug tracker. The best you can do for now is to check that the extension is tracking your tabs (colored triangle on extension icon), back up tab groups before closing Firefox, and hope that either extension author finds a workaround, or this bug is fixed in Firefox itself.
* Adding moz:extension scheme to url is the way to avoid tabs reloading when switching groups. If you disable Fast Group Switching, you'll disable url mangling, but you'll notice that all tabs are loaded at once. This, again, is a limitation of Web Extensions API in new Firefox, which doesn't allow to hide a tab, only to close it. And when you switch groups, you'll need to reopen them. I've heard that tab hiding has finally been added to Web Extensions API. Let's hope it's true, and wait for new version of Firefox which supports tab hiding.

Sad to see undeserved bad ratings.

Thank you to the guys working on this, rating is for digging deeper in Ticket #70 - random loss of tabs.

So far so good. God I've missed this functionality. Please keep up the good work.

Love this extension - progress and completeness to date.

It is solely responsible for switch back to ffox after drop-kick of ffox-57 lost 2 must-have extensions - tab-group and session-manager.

With SimpleTabGroup(2.3)
A bit disconcerting to have lost history on tabs when switch back to a group after switching away
- have to see if thats workable or can wait till mozilla's blocking api bugs fixed.

Good job on the tabs in groups grid layout - hope some more devt goes into this to have smaller group boxes/collapsed contents
so can see all groups on one page and can drag groups more directly to reorder groups more easily.
Good that can reorder groups on selection popup

(The popup list of Groups for selection to change to (edit, delete) is currently workable for smaller numbers of groups but miss the full page (grid) display for when have a lot of them - maybe its just a change I need to get used to

perhaps default icon for a group could be the mini webicon for the first Tab in it ???
- save individualy soecifying the icon for each group

Kudos to all involved in the effort made and progress so far..... ab-so-lutely f* Fabulous extn.

The tab hiding API has landed in the newest nightly.
