Just one word: Awesome!

I've been using this add-on for about a year now, and while it's hit some typical development roadbumps, it is a fundamental part of my browsing experience. It is simply a fantastic tool for organizing the hundreds of tabs I have at any given time, and backing them up as bookmarks is a fantastic bonus feature. I think there's a reason this add-on has been designated as "recommended" by Mozilla/Firefox - I wouldn't be surprised at all if they were looking at bringing the features of this add-on into the main FF codebase. IT'S THAT GOOD, REALLY!

Can't live without this anymore. Minimal yet very configurable.

Absolutely love this add-on! Any chance you can port it to Microsoft Edge Chromium? My company is going to blacklist Firefox in the summer :'(

Awesome! The best addon for productivity, does exactly what I wanted.

Lost some of my open tabs when played around with the plugin right after installation. Besides, that everything works just perfect for me. The integration of Multi-Account Containers is very neat. The STG plugin is just super helpful when you hassle with dozens of tabs

must install this.

Great add-on. Thanks for your time.

This Add-on has really changed my workflow. I've been able to keep the things tiddy, Work, Projects, Entertainment. It's kept distractions at bay.

Developer also listens to us!!! hence the comment below from my old review.

Former Review 2 Stars: This has the potential of being a 5 star plugin but everytime I open firefox tabs are duplicated or triplicated.

Nunca escribo reseñas. pero esta extension me dio justo lo que necesitaba, habian eliminado de firefox el agrupar pestañas en grupos. y esta extension me permitio poder hacerlo nuevamente. Muchisimas gracias.

The Very Best of the Best! Perfectly working, simple, fun to use, highly configurable, actively being developed from a very polite and professionally responding to concerns developer! HIGHLY RECOMMENDED!

the best extension ever
