Microsoft shut down my PC for a critical update and lost all my tabs!

Lost all tabs randomly. I followed guides posted by the devs to recover, but didn't work. I loved this app, but I can't use it anymore after this has happened twice in 3 months. You are better off making a bookmark folder and organizing you tabs in that as it's much safer.

I've been using OneTab, it was great until I've lost all the tabs (300+ of them) suddenly. I'm not entirely sure why this happenned, my FireFox is version 48.02 as I haven't been able to update it since my Mac OS has become outdated. Maybe the OneTab has become too new for my browser? I now see the "file not found" page on my OneTab tab, and I can no longer see the icon of OneTab either on the toolbar or in the list of add on-s...

Lost all my tabs, it didnt just not work, it actively ruined my browser organization.

This add-on is not ready for Quantum. When i Installed it crashed not only my firefox but also whole machine.
In Proccess Explorer Firefox had take in seconds whole 8 GB memory of my Computer without finally creates the onetab bar with me 230+ allready opened tabs. I gave it more than 20 minutes to work for build the bar but fatally didn;t make it.

I had to open task manager to kill the proccess tree of firefox for about 3 times, cause even after the first tries to kills the firefox proccess when i repopened it crashed again. Finally among 3th restart of firefox after a machine restrat it gave me some time to prior uninstall the addon and release the browser from this memory killer. Thanx Luck...i had install the session manager, cause after all these problems finally it had lost all my tabs from tabbar. I restored a previous session of past day and saved my tabs.

I hope they resolve the problem cause, it makes BIG problem to users.

I have only Tab Session Manager active and new tab tool not active

Great addon BUT after Firefox updating to the last version it not working and seems that my all tab history erased!!! The store.json frile is almost empty and there are no saved tabs there!

Several times all of my saved tabs have disappeared when Firefox updated -- and there is no way to retrieve them! This had appeared to be a very useful extension, but now I have no confidence in it.

Could you add the option to auto add to the one tab list tabs that have not been visited in for example a week? (With the amount of time being configurable up to a month or something like that)

Could you also add the ability to manually create new tab groups and be able to contract and expand the listed tabs on the groups?

i just suddenly lost all my saved books from this shitty extension.do not touch
