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 Since Firefox updated my tabs vanished and appear to have been replaced by a sidebar added to Firefox that performs a similar function but not as well as OneTab did.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.

This extension makes tab management super easy. I have had all my tab links disappear before, but they have always shown up again with a refresh or a browser restart. To be safe though, I do export my tabs occasionally.
I especially like:
- ability to name tab groups
- ability to lock tab groups
- ability to quickly reopen a tab group
- when my tabs get out of control, I send them all to OneTab where they are much easier to pick and choose the keepers and then sort them
The only thing that is mildly annoying for me is that I will occasionally hit the OneTab icon in my toolbar by mistake and send all my tabs to OneTab. This is a very minor inconvenience though because I can restore all the tabs almost as quickly.
