Metamask Firefox blank/white screen

I really don’t know why this happened. This happened to me today when I wanted to open Metamask.
I forgot to back up the seed phrase. I followed the instructions from here https://metamask.zendesk.com/hc/en-us/articles/360018766351 but it didn’t work.

Please help me. I have about $6,000 in my account. I am very frustrated with this problem.

Browser details:

  • OS: Windows
  • Browser: Firefox Browser 88.0 (64-bit)
  • MetaMask Version: 9.4.0

Additional context
I’ll give $500 to anyone who can help me get my Metamask wallet back.

Not working. I only have binary file from Firefox right now.

is there a fix for this?
I also am running into the same issue

I don’t know exactly to fix this.
But, if you can access your metamask vault from your firefox profile and there is a garbage characters, I know someone who can help you to fix that garbage characters.
But never give your metamask password. If you do not have metamask password, then there is a risk.

how to access the vault though?
