I don’t know if this has happened to anyone else or if there’s something wrong with my setups, but ever since I started using Firefox, there have been numerous times it has cleared the data stored in the extensions. A lot of times it happens when I sign into a new Firefox instance and the sync feature seems to think that the new instance with freshly installed extensions is the version I want, so instead of syncing over the extension data from my other instances, it goes ahead and deletes the data from everywhere. But sometimes, as in just now, it deletes the extension data right out of the blue. I have several privacy extensions and website script/feature blockers, with a lot of custom rules I have made so websites still work while being able to run the least number of scripts and revealing the least information about me, which are all lost now. It’s really frustrating and time consuming as I now have to set it up again.

So please, Firefox. Figure out how to not lose my customizations for no reason. Better yet, also give me an option to export the data for a given extension so I can back them up in case your sync fails or something else goes wrong.
