[Bug]: Metamask 13.44.0.0 on latest Firefox (154.0) doesn't load (loads forever)

### Describe the bug

It's the same issue that comes and goes every month, and the same issue I referenced in https://github.com/MetaMask/metamask-extension/issues/45376
When opening Metamask and when inputting the passphrase, the wallet just loads forever.

I've tried all possible remedies as offered by support.metamask.io, reddit and relevant online communities, including turning the extension on and off, granting and subtracting permissions, updating, etc.

I do NOT want to reinstall the extension, even though I have my passphrase, as I've imported a lot of external wallets that I do not remember if I still have the private keys backed up.

### Expected behavior

I'd expect Metamask to unlock.

### Screenshots/Recordings

### Steps to reproduce

Open Metamask
Get asked about the passphrase
Input it
Wait forever

Start by reproducing the unlock flow in Firefox 154 from the extension entry point shown as home.html#/unlock, then compare the console output with the related issue #45376. Trace the reported CSP, Snow, ObjectMultiplex, and Rive messages to determine which failure leaves unlocking spinning. Done means the official Firefox build unlocks successfully after entering the passphrase.
