I have not even started using it, and it annoyed me. No, starting automatically on all the windows is *not* a good idea. I do detest going through all of them closing this effing thing.

A fabulous extension with a very active and helpful main developer. The one star reviews should be ignored, as they are written by disgruntled people with minor problems. Like, well, in every site with star ratings.

Author is reporting unfavorable reviews to get them deleted so I'm posting my review once again, I also reported this extension as damaging because of that.

If you install this extension expect to lose tabs and never be able to recover them because for some reason this extension manages to make closed tabs impossible to recover.

Worst extension ever and It's a mystery how these extensions that actually destroy your data get recommended by Mozilla.

Not even Sidebery (which is a mess) made me actually lose tabs.

Edit: and completely unhelpful reply from the developer who also threatens to get this comment censored.

Usability wise quite complicated, this add-on mixes the concepts of tabs and bookmarks, which as such is an interesting idea, as most people use tabs as a kind of bookmark.

However, my greatest problems with the add-ons are
a) usability (I just don't understand when a tab is just hidden, when it is closed and re-opened from bookmark)
b) performance (unstashing re-opens tabs one by one which can easily take 20s for lots of tabs)
c) loss of history (actually the tab is not stashed, only the open URL)

The loss of history is my biggest problem which finally caused be to uninstall the add-on. A tab is often worthless without its history.

I really like this extension. The ability to - at a key combination - quickly stash what I'm working on for later, grouped by each event/date, is really clever! I like how it works through the bookmarks rather than trying to be a whole new system.

Sadly Firefox occasionally freezes while it is active (even though I am not doing anything with it) to such a degree that even Windows Explorer can freeze or restart (task manager can't open) and this is on a reasonably powerful gaming laptop.

EDIT: I've reinstalled this extension and everything seems to be fine after a few days. Perhaps I had installed something else at the time causing the freezing. Thanks again Josh for this great extension!

I wish there was a confirmation before closing tabs. I accidentally closed my 100+ tabs I was hoping to organize with a misclick, and was unable to restore them. I will not be using this add-on in future.

awesomeness

Great addon. Coming from Safari I missed the tab groups and after trying out a few addons, this one seems to be the best. It's the only one which syncs between devices, even to iOS devices as they are saved as bookmarks. Nice work!

Sorry Josh, I really wanted to make this work, but just 'don't get it'. If you could offer a better User Guide I might be able to understand, but as it is 9.30.22 I can't get the hang of it.
I have a load of tabs open, and want to sort them into different groups of interest, but couldn't find any instructions that helped me get the overview.
I'm sure it's really good, but not without a decent User Guide, TY.

I love Tab Stash!!! The grouping is insanely useful when I'm working on a research-based project for uni. The vertical sidebar makes the names of tabs readable, eliminating the need to jump between tabs trying to find a specific one when you have too many. I love that I can rename groups and tabs, and collapse groups and the sidebar. You don't even need to stash your tabs to use tab stash as your tab manager! This is way better than the built-in tab and bookmark managers. I've moved all of my bookmarks over to stashed tabs-- it allows me to see them way easier, keep them grouped, and access them quickly and easily. Reorganizing your stashed tabs takes only a quick second to click and drag, and closing or opening a large number of tabs is simple, easy, fast! I love Tab Stash. I do everything in Firefox instead of Chrome just because of Tab Stash. I tell all my friends to use Tab Stash. I keep it open in my sidebar incessantly when I need to manage a number of tabs. Tab Stash FTW!!!!

Works flawlessly to manage open tabs, and ingeniously uses existing Bookmarks functionality to stash open tabs. It is the Open Tabs manager that for years I've been searching for.

I really like the app, however it is using up way to much memory, and this is on a high spec MBP that's less than a year old. As soon as I disable the extension, everything goes back to normal.
