My #1 most essential extension. I use OneTab as a shortcut for making a quick research bibliography in my notes and it's incredibly helpful. It also helps me clear my space when I switch to a new task. I can't say enough about how important this extension is to my workflow!

THE VERY BEST. Just need a option to right click the tab(s) and "send to OneTab".

Superbe extrension permettant de faire nettoyage de tout ces onglets que nous désirons garder accessible, Bravo au concepteur!

ein ausgezeichnetes Add-On dass mir die tägliche Arbeit wesentlich vereinfacht!

Great. A bit clumsy in manipulating groups, but extremely effective in reducing FF crashes and slowdowns. Recent updates have solved several minor user interface problems.

Thank you for adding a dark mode.

Очень незаменимое дополнение особенно для тех кто ведёт много проектов одновременно

This is my favorite extension for any browser. I was mad the first time it crashed and when I noticed the high CPU usage but the solution is to backup your URLs to notepad using export in onetab before you reach 400 and then remove them from one tab. They are easily imported/exported back and forth. With notepad you can save different files for each subject.

Excellent..., Excellent..., Excellent...

es muy buena

super tool!
