Lost +52 THOUSAND tabs after a crash + update to Firefox 117. Happened a few times with Chrome (one of the reason I switched to Firefox) but I was able to recover those manually. Not here though.

This extension just works so incredibly well when it does; I will be looking for a GOOD alternative for a long time.

lost all my tabs of 6months randomly, dont use this

Very useful to tidy up my tab bar

great help and robust
One more feature and OneTab is perfect
The possibility of synchronization with all own installations
E.g. via Firefox Account, or Cloud

This works perfectly. Even saves the onetabs EVEN when you close firefox. Perfect.

All saved tabs were lost from one browser start to the next. Without update or special incident. Many hours of research are now wasted. Very annoying. I can only advise against this add-on - it does not work reliably

It's very convenient and easy. I will keep using it.

I am a massive nerd when it comes to my browsers... and I never fail to have over a 100 tabs open during a good research session. Research tabs has saved me so much; it's the best extension out there -period- for those of us who are nerds through and through and who like to use -and keep- countless tabs. It's hard knowing what tab is what, but research tab kills it. ROCK ON!!!

After one day's use, the pinned OneTab tab wouldn't load (just a series of seven dots alternative blinking), my other extensions' icons became unclickable and, worst of all, I lost all my carefully preserved tabs.
Update 2024: Nice idea, poor implementation, particularly as regards accessing and saving to named tab groups.
