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!

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!!

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!

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.

Easily the best Tab Grouping extension. STG comes close, but it's also sluggish and heavy on weaker computers, whereas TTG is quick and painless everywhere.

Absolutely fantastic. I usually keep tons of tabs open, and despite my best efforts it gets overwhelming to navigate and remember what's where. With this extension, I can easily organize them into different groups by topic (e.g. work, reading, art, whatever makes sense for a particular set of pages) and even switch between the groups with one click! Declutters the top of the browser, frees up my mental CPU if you will, and works effortlessly. I've set up a few tab groups today and I'm sure this will build up.

Also, unlike the popular "recommended" tab grouping extensions, this one doesn't have excessive permissions - just what it needs to run its own functionality. (Seriously, there's no need for a productivity add-on to "access all browsing data...)

If you're wondering which tab extension to go with, or you're put off by the permissions list of the others, definitely pick this one. Even aside from all this, it just works perfectly. Thank you dev!

Really helpful extension, you can organize your tab better with this extension. Make some groups of tab based on your choice and It can unload tabs of the groups that currently not active, this can minimize firefox's memory usage.

Thanks, your extension is really great! Lightweight and minimalistic, exactly what I need.

It would be nice to have some short manual on tweaking it with CSS, though, so as to avoid spending time to examine the sources.

Very handy. Minimalistic. Love it!

It would be super convenient if tabs could be closed by middle button click in the groups menu.

Hey! Listen...

     This is an almost indescribably useful tool once you get up and running with it. Having experienced this extension for awhile now, I can say beyond a shadow of doubt that this is the best idea since--- anyway!

     All of the features are as described, and work very well. Formerly I'd used different browsers for different things. Since the loading and unloading sets of bookmarked tabs prior to this involved more effort than just gearing browsers to a use. Now? I'm practically ready to give this guy a medal!

     Everything becomes so easy to organize, and using the automatic unloading and loading means that unlike the feature in Edge which slides tabs into a side 'pocket' which doesn't. Sliding them over in Edge just moves them out of your view. It does decrease the load from those tabs, but it's still bloating with data.

     So yes. This doesn't. This is good. You want good? You want this. Do it. Why are you even still reading this review? DOWNLOAD IT.

     Kids these days...

===============================================

Wow. Just wow...

     Okay, if you're reading this that means you still haven't tried this extension. Why? This is everything they advertise and works in a manner that's veritably even better than advertised.

     Well actually let me make this clear, ( even to chzesa the saint who brought us this! ) This kind of an innovation is in my opinion about as ground-breaking as when the first browser offered the ability to open tabs.

     The way you can organize tabs into tree's to stay organized into a tree format. Group them together to sort even more diversely. Then on top of all of that, you can also create entire tab sets! I have a tab setup for almost every activity now. It has dramatically increased my productivity.

     Those tab-group set-ups once stashed away no longer consume system resources unlike other browsers that allow you to stash them out of view. The problem is that it still consumes system resources in those little stash areas. Not with this solution. In fact, you can tie this extension with many combinations of others to make this extension more versatile.

     This extension is so awesome that I have come back to edit my initial review. That says a lot about the extension. I gave it a 5 / 5 originally, and wrote an extensive review. I came back to make even more praise for this extension.

DOWNLOAD NOW! :) Please.
