All my custom website permissions have been lost (10.1.6.3)

[NNSU]

I just ran Firefox for the first time in 6-7 hours. I noticed no website had working Javascript, and then realized by opening NS settings that the only customized websites were those that come by default.

I had been customising these settings again since the quantum version, and now I have to do it all over Seriously this is too disappointing.

If you need more feedback I can not say what has happened since. The PC went in suspend mode but Firefox has been closed since then. Did 10.1.6.3 get pushed today/yesterday?

NoScript allows you to backup (and restore, of course) your settings:

Either you permitted all the others by setting them to "Temporary TRUSTED", or something happen to your profile which deleted the WebExtensions storage area reserved to NoScript.
No way NoScript lose its setting by itself alone, anyway.
As FranL suggested, though, since stuff like that may happen for any data storage, making periodic backups is a good idea.

There have been multiple reports on this issue but no one can reproduce it yet. It seems to happen at random.
