I don't usually rate or review stuff but this extension is an essential productivity tool for me.

This is one of my favorite extensions. When it broke with a Firefox update it sent me into a panic (Firefox admitted the bug was on their side). But the OneTab devs came out with a fix and all is good.

This is well deserving of 5 stars.

One thing I wish for is a way to easily (even automatically) back up things so in case I lose something I can restore it.

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.

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!

Best extension, so easy to use. Wish it was open source
