Hey Luigi I also encountered this problem with my metamask in Firefox.
I followed the steps to take out the special characters with ubuntu but the file still has some characters that the decryptor can’t accept.
i can send you the file can you send me without the special characters? i still have the password so i can go to decryptor myself!
Thank you for the post it was super helpful i must be missing something!!

Hi @rdcf did you try to change the file number? As they advise on the github site: Blank screen appears when opening popup in Firefox · Issue #9196 · MetaMask/metamask-extension · GitHub
If you want 
write me on my telegram username.
You can find it in my profile: https://community.metamask.io/u/Luigi
