searching for tab outliner alternative in firefox, and this is it(much better than tab outliner in my work flow)

Recommend. Very handful addon for users that have lots of tabs and want to separate them into convenient workspaces. Thanks to the dev, I appreciate your work.

Updates after 2 weeks of usage: add-on works really smoothly. Didn't notice any bugs so far. Definitely recommend to use, 10/10.

Thanks for this wonderful extension. I came from OneTab, disappointed by not being able to sync the groups between my devices. With Tab Stash, everything works as a breeze. Super UI, great UX: I cannot imagine a feature I would miss. Tab Stash fulfills my needs.

Super easy to use and it does it's job perfectly.
It has quickly become my favorite extension

Edit: the 3.0 update is AMAZING

Great for saving sessions. Although I do wish it were compatible with Tree Style Tabs. It would be even greater if Tab Stash saved the tab nesting as well.

I've been waiting for that app for so long. Just a simple tab managment that do the job : group your tabs and manage them in a couple of clicks. The UI is clear and convenient, straight to the point. Much better than the other top-of-the-list tab managing apps which are blotted and so complicated to use.

Before I used Firefox I was an avid user of the chrome extension "OneTab" and I planned to use the same extension with Firefox but then I found this and its like OneTab on steroids! It perfectly lets me organize all the tabs I am not actively using into neat groups and it syncs between my laptop and desktop. Truly changes how I'm able to use my browser I love it!

This extension is an amazing complement to bookmarking, than you very much Josh!

I want to share my bookmarking workflow.
First of all, I am using “regular” (Ctrl+D) bookmarks for permanent or long-term bookmarks, i.e. those I'm likely to return to in months or using frequently. I'm no longer sorting my regular bookmarks by folder; instead, I'm using tags. When bookmarking a page in this way, I'm changing the default page title, for example, instead of the default “Acme Manangement LLC - Home” I type “Acme Management LLC - Contoso Gardens Condos - My HOA,” so I'm more likely to hit it when search bookmarks (Alt+D to go to navbar, type "*[space]", and you're in bookmark search mode, if you missed this FF feature—I had! Maybe tags aren't even necessary, if you name the bookmarks in a way you'll likely to hit them: add as many keywords to the title when saving.

Tab Stash, on the other hand, is an excellent Kanban-like complement to my postponed tasks, or grouping of related tab sets that I will return in a short time. There's also the pencil icon, so you may rename the page's title so it's clearer later. I also mark groups with a date, in an ISO-like shorthand like 230528, YYMMDD. I rearrange work postponed work the higher priority closer to top. Of course, plans change, some of them sink down. Once in a few months I scroll down through the stashes, and clean those that I abandoned, or restore and Ctrl-D bookmark them if I wish to keep them for a long term.

Finally, a spring cleaning is an early pass through Ctrl-H FF's own bookmark manager. I don't spend too much time thinking; delete what you know you won't need. If you hesitate for a second, leave it. This prevents accumulating tens of thousand dead bookmarks—you won't remember why you bookmarked an obscure one in 2-3 years anyway, so it gets cleaned by the above yearly “clean what you know you don't need, or have no idea why bookmarked.”

Bookmarking and stashing naturally complement one another to keep my bookmark organizing business efficient. As a bonus, stashed bookmarks show up in the bookmark "*[space]" search along with regular bookmarks, so I can pull what I still remember even without going to the Stash toolbar.

YMMV, but to me, this plugin is the second best invention po Velkopopovickém Kozlu!
