Support unsigned custom browsers

Hello t3rminus! 👋

Thanks for reaching out. On macOS, the 1Password app verifies the browser’s code signature for authentication when it establishes the connection between the app and the browser extension. This authentication is designed to make it difficult for other applications and malware to intercept the account information and encryption keys that are passed through the connection. Without this authentication process, 1Password is unable to verify the app that is trying to communicate with it.

With Librewolf not being signed, the two available options are:

1. Use 1Password in the browser without app integration.
2. Use another browser that is signed by the developer.

That being said, I've passed your comments along internally and the team will continue to look out for ways to give users more control without compromising security.
