I tried a lot of different tab group extensions, and they all need so much memory, have an overload of additional functions, and the most important thing is that they all are so slow and lag when switching between their groups.
This extension right here is the most efficient, cleanest and fastest tab group extension ever. Highly recommend!

Added a tab to it, and when I opened, it replaced all my other tabs. Had to uninstall

There is no information on how to make this extension work, I've tried twice, searched all of the net and giving up.

This is one of my favorite add-on for firefox. Simple to use for users who keep 100+ tabs open like me. :P
Hope to see New features added to Tiled Tab Groups in the future!!

I'd prefer if the tab groups could be visible on the tab bar itself, but after a small amount of testing, it seems pretty easy to use and hasn't lost my tabs on close or restart. I'll just need to get used to hitting F2 to check in on my other tabs/remember they exist

Why does every extension can't group inside the current window ? Edge, by default, supports that...

Really amazing! I've used it for a couple of months now and it's worked great. As someone who is always working on multiple projects at the same time, this is a fast and ieasy way to manage all of my tabs. Highly recommended!

Worked fine for a year or so. I was quite relying on it, let open all the tabs I was reading for my thesis, and then suddenly, nothing: all groups, tabs, and recently closed tabs have disappeared. Even my pinned tabs, which should have no link with this extension.
Be carefull not to rely to much on this extension !

Not so good. It works fine, until all tabs and groups disappear. This happened to me twice, basta, I uninstall and only one star. Avoid if you REALLY care about your open tabs...

0.18.25 . Not functional. Shows a single group, not what is in it. No button to add another group.

Great, but i would like to customise the F2 button for configurating tabs, because i use it in cloud storages to rename files.

Useful as a lightweight alternative to extension "Toby for tabs"

This is exactly what I was looking for. After checking so many other bloated add-ons, that were "recommended" this was just the right thing, with minimal permissions and feature bloat. And it retains everything on browser restart.
If I was to request 1 feature it's would be an option for multiple windows using the same groups, but that doesn't seem to be doable with how Firefox handles tabs.

Created an Add-ons account just to give this one 5 stars.

Superb extension, have been using it for a while now and it has become essential to my browser workflow.

Thank you so much for this tool; once you get used to it, it is extremely user-friendly and reliable. Cheers!

Edit: I'm dropping by to give some feedback now that I've used this add-on for a long time. First, I'd love to have some documentation into how to use the visual CSS customization, I haven't found any.

Secondly, I'd love to have an option to hide unloaded tabs from a tab group (For example, my music tab group, i have a lot of playlists and genres for different moods, and unloaded tabs really clutter my view), I imagine this could be possible with the tab hide api.

Once again, i applaud this add-on for making the user experience of firefox phenomenal, I'm honestly proud to show off my browser hahaha. Thank you very much chzesa!

Want to simply select some tabs and move them to a group? This is the extension. Most other add-ons require you to group all your tabs with a cumbersome setup before they're usable.

Unfortunately, in Windows 10\Settings\High Contrast the extension settings page is all black, impossible to read
