after I updated windows10 to build.10568, firefox add-ons are removed themselves everytime I reboot my pc.

this never happened for several years since I started using firefox. (from win7, 8.1 to 10, on 4 different PCs)

I tried turning on w10's administrator account, formatting system partition and clean installing the OS, using latest beta version of firefox.

Nothing changed.

is there any clue?

It is possible that there is a problem with the file(s) that store the extensions registry.

Delete the extensions.* files (e.g. extensions.json, extensions.sqlite, extensions.ini) and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created when required.
