Works fine but lacks the ability to gather pinned tabs even using its option to send all tabs to OneTab. Would be nice to be able to merge all sessions into one and sort by name and delete individual items...

It works, but with caveats. I'd recommend you check out Tab Stash before using this one (an excellent alternative worthy of the recommended badging) but if you want to use this specifically then heed these warnings....


One: The extension's icon in the extension bar is a nuke that automatically saves all open tabs in an individual window into OneTab, CLOSING THEM IN THE PROCESS. If you are (rightfully) scared of activating this nuke by accident, remove the extension icon from the extension bar asap. Virtually everything can be done via context menus anyway.

2. If you share tab groups as a webpage, it will be searchable on Google until (and unless) you delete the page on the page itself. Otherwise, anyone can see it.

3. OneTab is a RAM hog that will eat up CPU and Battery like nobody's business.

I give it 3 stars because it does work fine if you keep these in mind, but Tab Stash does nearly everything OneTab does but better (thanks to it's use of native Firefox Bookmarking instead of it's own engine). I'm shocked that Tab Stash isn't recommended by Mozilla yet, as it's better than OneTab in nearly every way.

I have had some 120+ tabs open, many of them having its own history of a few pages visited. After using OneTab, I've lost the history behind each individual tab...

Simple and Easy to Use. Would be great if it can form trees

I don't ever want to go back to my life before I downloaded this. THANK YOU! It's so simple and yet everything a power user needs. 5 stars ☆

Extremely useful

I hate this add-on, because of this oneTab my unsaved code is lost. My two days work!
