Can't give 5 stars yet until I've used it for more than a few days

It is the most used addon by me... cannot live without it!
It saves my live

A simple solution to managing tabs. Not only that it's flexible for temporarily organizing tabs, it allows you to export the list in a convenient way (just copying the HTML, or saving as a web page).

i love the idea really

Great! I can easily save my tabs for later with this extension. One major problem: This is not free software. Come on, it is not that hard to do that.

Love this Plug. I usually have way too many tabs open which consumes tons of resources. Tab solves that issue. Great job guys and gals!

I want to customize button function. Because I use "send only this tab to OneTab" most ofen. So I want to use it one action. Thank you!

God job

Could use some sorting, search and more advanced options since the list is becoming very big.

eine großartige erweiterung :)
ohne onetab wäre ich längst unter dem berg meiner tabs begraben! zu schade, dass es noch keine version für android gibt!

Broken. This is my favorite add-on but it has stopped working in a catastrophic manner and I just lost all of my tabs. The "bring all tabs into Onetab" function closes all the tabs and windows *but doesn't add them* to the one tab extension. It just threw away all of my tabs. This worked before firefox 57 and yes I am using the updated version. I even uninstalled, restarted, installed the latest version, purposely opened multiple windows with multiple tabs and tried again just to test it... only for it to fail again in the same way. Now I have to go through the history and manually find the 50+ tabs it trashed earlier and switch back to Chrome. They don't even show up under "recently closed". This add-on is essential to my workflow so Chrome is the only option now. tldr: Works perfectly for 1 window, fails epically at multi-window. Was a 5 star, now a 1.

Such an elegant solution! Thank You!!!

...but FF 58.0.2 is still so slooow. :-(
