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.
