Support for Orion Browser

Thanks for looking into things ag_Christian, that all makes sense and will try updating on the nightly channel again. I'd personally vote for the code-sign requirement to be loosened (maybe showing a danger alert when an app is self-signed but still allowing the user to override?) given that many open-source Chromium builds aren't codesigned with Apple developer program certs—but totally understand if that's a bit too far for 1P's comfort with regards to security given the scope of access being granted here. Will note that the 1P extension otherwise works as expected so it's not a huge loss either way, just need to login to each vault manually and type in the master password more frequently.
