Works on my Android phone (Samsung) and so far is the best extension on FireFox for grouped tabs. However, even if they add that feature to FireFox mobile this add-on will STILL be useful since you can actually save and completely put aside tabs and have a clean tabless page when needed while still having saved tabs. Absolutely incredible.

Dev, please figure out what is wrong with your add on. Since Firefox updated my tabs vanished and appear to have been replaced by a sidebar added to Firefox that performs a similar function but not as well as OneTab did.

Perhaps OneTab being in the same location as the sidebar Firefox added is the cause of conflict? Auto Tab discard is functional and it does not use this same area. Tab Session Manager also works fine so that was the only logic I could think of. I love using this add-on and hope you'll take time to sort this out as it was the reason my computer RAM was being drained entirely and had been crashing out. I had to remove it to make that stop.

PLEASE fix, I'd love to use it again and I hate what Mozilla has done to replace it with their own sidebar. Can't you relocate this add on to the other side of the browser bar? Thanks for considering my request and I wish you the best of luck in this effort.

Excellent way to organize my study searches and save memory and CPU

Good extension, does everything that an AddOn like this should do.

To all those who write that all of your data is lost in onetime.
Have you tried making a backup locally on the hard drive, after 100 pages saved in OneTab? Or do you all think that you can save an infinite number of pages without the memory running out?😒

very simple and easy to use

Fantastic tool and has been often reliable. I would pay them for this if I could.

This extension is very useful for me that need to open many tab and collect information.
