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!

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!

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.

very useful to me! Can even sync between devices

I really like the idea of storing the groups as bookmarks folders. Making it more of a better UI for bookmarks (which is sorely needed). I also make it simple to ditch the extension if it doesn't work out. Also provides seemless sync between computers.

Highlighting the pages which is opened as tabs is neat.

I hung my browser multiple minutes forcing me to restart firefox. It had then created duplicates groups. Not sure what happened, but it seems to behave now. The UI for moving tabs between groups has some weirdness when trying to move pages which are open?

Would be great if it was possible to select multiple pages (with shift-click to select range) to simplify organizing the stashes (but I guess doing such operations from the native bookmark manager is ok.)

EDIT: seems to be a bit slow to load sometimes. Maybe I have to many bookmarks?

Highly recommend swithing to this if you already use eg. OneTab

it can't get any better than this. It's perfect! cleared the clutter

So far excellent. Simple and seems reliable (only used for a day). I would suggest the following if it didn't impact stability:
-Allow easier selection of only one group to export (export option next to each group instead of higher level menu?). It took me a while to find the export button.
-Keep the chosen export format between exports or firefox sessions (or alternatively, let the user select the preferred export format in the settings)
-On first use after install, Default setting when pressing the stash button should be to open the side bar menu. When learning a new add on, its always a bit worrisome when it starts to stash or store hundreds of tabs when you first press the menu bar button. Users can change the option once familiar and comfortable with the add-on.
-Add-on should have option to add to stash without closing or hiding the tabs. I could find no such option.

I did have the add-on crash while storing tabs for the first time, but the feed back on the crash was very well done, front and centre on the side bar so I realized what had happened, and the ability of the app to recover from the crash without losing data was impressive for an add-on.

The add-on appears to run very efficiently, isn't trying to do too much, transparent without doing something in the background without showing it's progress like so many other tab add-ons which take over the computer without showing the progress or if they're stalled or crashed.

Love the colours on the buttons giving an idea of how critical a task is (white, yellow, red). Love the undo ability in case I made a mistake.

Excellent design. Good job so far. Love the simplicity. Still a learning curve, but easier than most tab add-ons.
