3 suggestions that I think would make it even better:
1. Export as json/csv - Would be useful so that I don't have to keep a .txt file laying around with the urls and instead have a formatted json/csv file.
2. A way to search through the links on the OneTab page, currently I use ctrl+f to do this, but I think it would look nicer if it had its own search or if when you searched it narrowed the results down from all your tabs so there isn't a bunch to look at.
3. A more secure way to save OneTab tab data that isn't exporting/importing them. I'm not sure how this could be done, but according to dozens of reviews, their tab data was lost for seemingly dumb reasons that shouldn't occur.

Awesome add-on. Simple and most convenient.

Just one little thing, when exporting/importing the group names are lost.

One of my favorite extensions for Firefox. It has its limitations but suits my use cases just fine. If there was one thing I would wish for it is the ability to intelligently sort and categorize tabs.

absolutely goated update, added features were much needed thank you!

One of the best Firefox extensions.
I only have one suggestion, an option to send only selected tabs to OneTab, because sometimes I want to send 2 or 3 specific ones and there is only the option to send all to the left or all to the right.

Fucking awesome!!
