BRILLIANT! Simple, intuitive and classy. Open, create groups, drop and drag tabs between groups, then choose any one from the icon on top at any time.
I figured it out in 10 seconds, made 3 groups in 15 more, filled them in 20, and now just have to click their icon up top, and choose one of the three groups (which you can name, and which have a little color on each one).
This is a case of programming perfection: it could not have been made better!
Change colors and change icons or add your own in several common formats - download anything. Nifty!
I even grabbed a 1200x1200 pixel jpg off my PC and it worked, and shrunk it perfectly. Most websites choke on 128x128. Dude! :)

Un pur plaisir à utiliser ! Si vous aimez grouper vos activité, et économiser de la RAM en pensant de l'une à l'autre, alors cette extension est juste parfaite !

As I often work on different products and different release versions, I love to now have the possibility to create groups based on product/versions. I used to have all important Jira tasks in one window (as I do not like to have several Firefox windows opened at the same time), but thanks to this plugin I can now have them divided in different groups and switch between them easily. Pinned tasks stay visible allthough I am switching between groups which makes this plugin even better! Thank you Drive4ik!

I recently switched from Chrome and I was expecing something similar to the tab grouping feature in Chrome, since this Firefox extension is so popular and comes with the recommended tag. Instead, I got a horribly unintuitive tab grouping experience, with tabs hidden god knows where.

This one is a tab hiding extension, not a tab grouping extension.

Installed and immediately added all of my open tabs to a hidden group, each of which requires several separate clicks to unhids manage or move to another group. Not visible from the extension manager, options hidden and unintuitive. Really shoudl be a basic browser functionality but not worth installing this even as an interim solution

it's perfect
me <3 containers

I'm using this addons for years and love it.
Little bugs with Tile Tabs WE addon.
Not working with Floorp browser.

I love it. Took me a few minutes to figure it out especially connected to container tabs, but I cannot do Firefox without it now. Thank you!

Buggy and unintuitive. Any time I tried to use this add-on I thought I was going to lose all my tabs just trying to get them back out of a group.

I wanted something that actually MOVED a tab into an actual group !! Not just tagged an open tab as being in a group !!!!!
With this extension, as soon as you have added the tab to a group, you think "I can close it now, it's in a group". NO IT ISN'T ! You close the tab and it's gone ! Pretty pointless extension !
Totally doesn't do what it's name implies !!!!!

The backups of this addon saved me all my tabs when the shitty Firefox 127 update decided to nuke my whole history/open tabs etc without a way to restore it. Just trusty old STG churning out backups which I could restore from. Just for that the 5 stars are justified, but on top of that it also is a very useful addon.

Great add-on. Coming from chrome it takes a bit of getting used to, as it isint as polished and intuitive. I really do only have one problem with it tho:
For some reason you cant specify where the backups folder is placed. It just defaults to where firefox's downloads folder is. And i dont want this backupfolder to be in my downloads. plz fix.

Why does it need permission to "access your data for all websites"? A tab organizer shouldn't need access to my passwords I am typing to a website.

If you have more than five tabs open or more than two windows to separate your tabs thematically, do yourself a favor and install this add-on. If you're a keyboard shortcut lover, set them up and enjoy the organization of your tabs taken to the next level.

So far 5 stars, but I haven't used it that long.

It allows me to create groups like in Chrome, but unlike Chrome, these simple tab groups replace the all the previous tabs you have open (when you switch to a different group).

Other extension open them in a new window and load them all, which I don't want, I mean I have groups with 1000+ tabs in them and loading so many can crash weaker computers or cause certain websites to block you.
Others like Chrome open the new tab group in the same window making it cluttered and unorganized.

Your ungrouped tabs are not lost when switching to a group, but I still recommend creating a group for them, just call it 'casual' or 'random'.

And unlike new windows or Chrome tab groups the 'vacation' or 'job hunting' group you weren't supposed to be looking at at work can be quickly switched to/from and perfectly hidden.

I was afraid it doesn't have backup options, but thankfully it does.

This plugin and Download Manager (S3) made it so I can pretty much switch over to using Firefox instead of Chrome, and that's pretty huge.

очень простое, но полезное расширение
