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

Lot of customization options & a bit confusing to use at first, but once you figure it out very convenient! This will be a great hold-off until the Firefox team offers a native, built-in feature.

great addon. thank you so much for creating this : )

sudo apt update
sudo apt upgrade
sudo apt install rpi-connect

matchbox
sudo apt install matchbox-keyboard

It really help ,e save a lot of time and effort. Before I have to open multiple browsers to do various works but now I can Freely use mozila to do all of my work.

WHY WHY WHY WHY would you REMOVE the saved bookmarks folder of a group when you remove the group itself??? Otherwise great addon 5/5!

je m'en sert depuis plusieurs annees, je ne pourrait plus m'en passer maintenant

Absolutely love using this extension as it helps me get ahead on work by simply reorganizing my tabs on Monday nights. The Manage Groups page is essentially my DEV dashboard for my work life.

Would love an addition if possible - adding the ability to rename tabs.

My current solution is using Firefox's tab inspector, finding the title element in the page's head, and rewriting it. It's a local change, but it makes my tabs sing in the Groups.

I use this extension instead of the Bookmarks feature of a browser. Thank you for creating it!

Easy and simple. Love the unload from memory feature.
