Extremely useful! Makes cutting through my usual tab clutter a breeze. Also automatically detects and prevents the saving of identical URLs. I have now organized things by order of importance and category. Saves RAM and keeps the browser quick!

This application is so simple, but I can't live without it. It is so useful. Thank you to the developpers.

I *highly* recommend this add-on. However, since a recent Firefox update it has crashing my browser when I click the OneTab button.

This is with Firefox 68.0.1 on Linux.

This is a fantastic Add-0n, very grateful for the developers who keep adding to this wonderful too.

great

Cannot live online without it! Pure gold!

This used to work well, but the last few months I have kept opening Firefox to discover I don't have any tabs or even "One Tab" I am totally fed up with it!! Rubbish

I lost all my tab, and the file storage.js was modified 4 months ago.
