Excellent extension; essential for anyone that gets easily overwhelmed and/or likes to separate their tabs by topic or workflow.

Allows to organize hundreds of tabs.

Simply The Best tab management feature

Extremely useful add-on and well implemented features, such as treating certain windows as a group, and even switching to them if there's already a window with that group opened, makes multiple workflows extremely easy to implement!

Works fine for me. I use 5-7 groups for the various customers I work on + 2-3 for internal projects, with 4-5 tabs in each group. It allows me to keep tabs open when I come back to a group, which I find invaluable. I could achieve the same result with bookmarks I guess, but I'd have to open the tabs vs using STG, there just update.

OK

Best one around. Fast leaning curve and super efficient, tabs are clearly organized. A global view allow to move tabs from one view to another, or to perform a global search.

@Exa Smith: Hidden tabs that does not belong to any screen can be recovered under "show other tabs" at the bottom of the menu. Then you are offered with several options like moving all these tab under current screen, or create a new screen for them.

the best extension i ever used

This is a great ad on for organized people.

I signed up just to leave this review, lol: This add-on is absolutely wonderful and I can't even begin to imagine using Firefox without it. Being able to organize tabs into different groups is a game changer. And being able to easily switch between them makes research (for Linux, gaming, writing, entertainment) is simply wonderful. It's also easy to use, to move tabs around and to save and backup groups. It even saves ungrouped tabs for later. I love this!
