First time I tried to use it, it closed all my tabs (nearly a hundred that I'd kept open across crashes, reboots and FF updates for months) and gave me a list of only the most recent two. I think this is probably the first time in my life I really feel like I could murder someone. I'm sure it will pass but it won't stop me hoping the developer gets hit by a bus.

One of my favorite apps. Would be ideal if one can move more than one tab in the list at a time to a new and/or existing group.

Does not respect hidden tabs, therefore cannot be used with Simple Tab Groups or other tab managers. Completely useless in it's current form.

I've used this extension religiously for years on my desktop and I love it. However, I just installed it on my Android phone and upon using it, it deleted ALL of my tabs and didn't even save them!! I had over 100 tabs open and now they are gone! I am EXTREMELY disappointed.

Simply awesome and easy to use. I wish I can auto-backup to google drive though. That would elevate this plugin to 6 stars!

Love it and highly recommend. A true game changer.

Works well on both Firefox and Chrome, and I haven't been bitten by the issues that other reviewers mentioned. I'm taking one star back because import/export drops all tab group metadata (name, star, lock), which strikes me as a strange and inexcusable omission.

Used OneTab for desktop Firefox forever, I installed it to use on my Android phone and it deleted ALL of my tabs which are now unrecoverable!!! DO NOT USE OR YOU WILL LOSE YOUR DATA!

I rarely rate add-ons, as so many are really not much cop. This add-on, for me, is one of those rare ones that ticks my boxes - it's clear what it does, it's simple to use, and I find it genuinely useful!

If you are one of those web users who sometimes has many Firefox tabs open, this really does simplify keeping a handle on them. Recommended, unequivocally!

Perfect extension, VERY useful, its like bookmarking BUT BETTER, although I did go into firefox's task manager recently and it was the process with the highest power draw somehow, even higher than all my other tabs like youtube

I read the 1-star problems of losing tabs so I tested this install with 40+ tabs.

40 +tabs open. They reduced to one tab and Task Manager showed savings. Hit restore all and they all came up fine.

closed FF and did it all again. This time saved the single OneTab bookmark and closed FF without restoring the 40+ tabs. Restarted FF and opened the saved OneTab bookmark. All previous tabs were listed. They opened both individually and as a full group and worked fine, including this page.

Seems to work fine. I'll keep it.
