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

It's almost perfect. One thing is missing: an optional ability to remove empty tab groups (with unmodified title) automatically. I guess, this would be a quite easy feature and could help a lot.

Immensely useful extension!

It can be configured (per-group!) to unload tabs from inactive groups, making it possible to have >100 tabs open on an older laptop with little memory, somewhat like Snooze Tabs but more organised.

It also has a sidebar with a searchable vertical tab view, which I've found less of a faff to use than the Tree-style Tabs extension.

It integrates well with the container functionality in Firefox, and the dark theme isn't broken.

This one feels a bit like uMatrix in that it's one extremely well designed and well thought out extension that does the work that you'd otherwise need at least half a dozen other extensions for.

Although it may be difficult to grok at first (as in "Why would I even need tab groups as well as tab containers?"), this is super helpful for navigating tabs, keeping focus on specific tasks and improving browser performance.

Me gustó el complemento, me parece fácil de usar y mejora la gestión de pestañas.
