after a power outage on my Win 10 machine my Metamask-CryptoWallet-Addon doesn't work any more [according to Google it's a known problem for 3 years...].

I have backups of C: and restored all Folders with "Firefox" in the path, e.g. C:\Users\ ...\AppData\Roaming\Mozilla\Firefox... (including the file

But the addon is STILL broken. So Metamask must save some data somewhere else... But where? :-|

Any idea?!? Thanks for any help!!

In current releases extensions store their data in indexedDB (storage\default) in the profile folder, but they use a random moz-extension:// (moz-extension+++) URL that is mapped via extensions.webextensions.uuids stored in prefs.js, that can be inspected on the about:config page. You may have to contact the author of the extension om how to restore its data.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).
