OneTab Team, have you never heard of user-level queries or safeguards?
This add-on desperately needs them, and hopefully you're clever enough to figure out the rest by yourself.

OneTab has been around for so long now and it still feels like just a proof-of-concept type of add-on. It's missing options and features, and it seriously needs some kind of overhaul with a focus on performance when handling more tabs & groups.

Have lost all my saved tabs multiple times after my browser updated. Do not recommend at all.

saved me and my computer. recommended for people who likes to go into rabbit holes and so have too many tabs open

I'm happy with this add. It offers many useful features

find yourself

Tnx

Working great so far - I had 4 digit number of tabs open! The only initial problem I had was that the first run seemed to use a huge amount of RAM on Linux and Firefox got oomd'ed ;o) After that everything seems okay - I don't think I lost any tab data. I think it would be better if it asked before executing the first time.

It would be really nice to have a search feature to narrow down the OneTab list
