This is what I needed, a simple tab saver that can also be used as a tabs manager. Gets the work done easy!

This is exactly what I needed. What a great extension. Does exactly what you want and gives lots of flexibility in how you want it to work. Highly recommend!

A very good extension. I could at last drop OneTab. But it would be nice to have read-only groups, because the majority of my saved groups are reusable. And I always fear to press the wrong button (and remove group instead of opening it). 😊

It seems as though I'm having an issue most others are not encountering, so I hesitate to give a poor rating, but after installing this add-on, I noticed my browser slowed down considerably. Extremely sluggish and frustrating, to the point of being unusable. I verified that this is due to the add-on by using Firefox's Process Manager. The 'Extensions' process hovers at 1-5% CPU usage when I have this extension disabled. When I enable it, it rises to between 50% and 100% CPU usage, and stays that way even 10 minutes after enabling it (which I did to ensure it wasn't just a start-up cost). It drops again within seconds of disabling the extension. I do have a large number of windows open, which may be part of the issue, and my goal was to reduce that number using this extension. However, I could barely get a single tab stashed in 10 minutes, so unfortunately, I'm not going to be able to use this to get to that point. I hope the developer is able to identify the source of the high CPU usage I've experienced, as it otherwise seems to be a very good extension. Will check back in a few months and try again.

Takes the standard bookmarking system of old and improves upon it's usability in every regard I could imagine.

every use case I could think of with this plugin over traditional bookmarking is just more fluid and quicker:

selecting bookmarks to move is based on checkboxes rather than mouseclicks plus control/shift key.
moving bookmarks to a folder is as simple as clicking a button hovering near desired folder rather than needing to drag and drop, risking a misclick mistake.
If I stopped to open up a bookmark I don't recognize to check it out none of the checkboxes already selected disappear,
this addon also integrates into the old bookmark system rather than replacing it so import/backup and sync works perfectly fine and directly modifying the bookmark folder itself doesn't result in any detrimental effects from what I've observed.
After this addon had already impressed me, I thought to myself that the text of the folders/bookmarks seemed small and experimentally tried a classic ctrl+mousewheel and found that the madman had considered what I thought to be an edgecase was considered and supported.

Best addon I've ever seen after uBlock, very well thought out and executed refinement of bookmarking. so good that this should, in my opinion, be incorporated into official firefox browser releases.

Quite simple and very useful. Helps to organize tabs and thus thoughts/ things to do.

I should have been using it earlier.

So, you're telling me I can have a beautiful, sleek UX/UI like OneTab, SessionBuddy, or Taby...

I get seamless syncing, just like TabSessionManager, but without needing a Google account or reconfiguring every new device.

And all my tabs are saved as bookmarks, so I never have to worry about losing them and can use Firefox Sync to access them anywhere?

Where has this extension been all my life? I swear, I wish I’d found it sooner!

I love how simple and practical it is. The fact that the tabs are synced to others computers is a game changer and makes me a lot more productive!

Installed a couple of hours ago. So far I like everything. But I haven't figured out yet whether I can sort tabs in groups alphabetically?

Beautiful extension, perfect for what I was looking for, has massively enhanced my workflow.

Fantastic extension, works just as intended. I feel a lot more productive with this extension!

Starred on GitHub ⭐ (which, funnily enough, has more stars than on here..!)

My only problem is that the Tab Stash allows you to save duplicates.
