We are able to capture the error / stack with vanilla JS. Tried sentry too. Wondering how would it help in debugging. What we have is the error message and the user agent but unable to reproduce the same problem unless we no more about the extensions installed or if the user agent is fake.
I was wondering if it's possible for e.g. Sentry to list installed extensions, but that'd give websites another means to do fingerprinting, probably not a good idea for browser manufacturers to have implemented.
