Best tab manager (because all other just dont compete) Rated 5 out of 5 stars
Everybody knows that Firefox tab management is. actually, totally broken. While you have 10-20 tabs its all great, but get 500-700 and...you dead, man. Panorama not helping - its slow and all tiny thumbnails, there is no way to list tabs at all.
THIS extension, while not being ideal, imho, is making its possible to manage your mess. Al you get is side menu with list of ALL your tabs, way to quick close them, also search, deduplication. And all that with SMALL perf footprint. I have more then 1000 tabs and extension like OneTab just go insane, while All Tabs Helper do its work without problem.
I recommend to also use Multiple Tab Handler and UnloadTab to get even more control on your tabs.
