Really useful to save multiple links to a single page for later use. It would be useful to have an UNDO button, for when one clicks on the toolbar icon mistakenly, then all the organised tabs (using Tree Tabs) are put in one page.

Do not use on Android! Removed all my tabs.

I really like OneTab but keeps disappearing from Firefox. I do not have that problem using it in Chrome.

keeps track and saves your search history such that it's easy to look back and find what you were seeking b4. However very annoying as it opens without input from you everytime u open ur browser and then you must close it. Delays your browsing due to this.

Every time I open Firefox on Android it duplicates the Onetab tab. Half my tabs are Onetabs. I love it on the PC, but it's God awful on mobile.

Excelente: É muito útil para os estudos!

If there are any Private Browsing tabs open, activating OneTab will add only those tabs to the list, while permanently closing and discarding all of the non-Private tabs.

A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.

I will rate with 3 stars because addon developer created this addon. If mozilla made this add-on then I would rate it with 0 because it doesn't even deserve a rating of 1. I am still using Tab Groups because groups are totally hidden and I can backup all groups and tabs with just a few clicks. In less than 1 minute I have 100+ tabs on my laptop.

What I need to do is foud a developer, then pay him to hack Firefox version 54 and change it with latest firefox version.

Latest firefox versions is totally the same as any other browser -> GARBAGE.

100 tabs use only 1 GB of ram :D why do we even need x64 if browsers are NOT even created to run more than 10 tabs!!

Running 50+ tabs without Multi-row no thanks!! I will not have my tabs in second window, because Multi-row do the job perfect and I can see tabs names without clicking on anything!

I like browsing fast and with less clicks and not with more click to do the same!

For example new sidebar oh my good!!! By default sidebar on the left side and icon for open/close sidebar on the right side :D :D :D Every time moving the mouse on the entire screen :D do they even have brains??!
