Really good at stashing tabs away, sort and group them, find tabs again and start working on separate topics in a natural way.
Everything is stored in your bookmarks, combine this with Firefox account sync and you can use it also on mobile, directly accessing your stashed bookmarks/group.
EXCELLENT add on!! Thanks a lot!
