I created the account specifically to write this review. I downloaded OneTab to get rid of old and redundant tabs that I had left open. After it succesfully merged them all in one tab, I proceeded to delete the unused ones. After restoring the session my firefox froze and when I opened it up again literally all my tabs were gone.
For many years a lot of people were telling me that I would be better off using using bookmarks more and I think OneTab is all I needed to make me switch.

this extension is a life saver wish i had found it earlier.

This is a must have for researchers, snoopers and the average brained investigator. This extension allows you to categorize what you've been searching, title the bundle in a nice little list, save, lock, create a webpage for sharing and edit. It takes some practice to manage the finger skills and proper drop downs to get your first collection just right. So, play with it while you create your first collection all in OneTab.

Very good add-on.

Hi, congratulations and thanks for a great and useful add-on. I use Firefox 78.0.2 and think to use OneTab in a long term. I need to know HOW to make a backup of the saved tabs and entire last status of OneTab in the case of accidents, system crash or just upgrade update to new Firefox version under other system user name. I am talking about Export / Import URLs since it don't preserve dates and other important data, plus that's a simple url's backup. I mean a way to create a TOTAL backup in order to restore everything in my last OneTab occurrence. PLEASE! is urgent to me! Thanks in advance.

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.
