Started this morning. All of my personal tools like nextcloud and RSS reader were blocked, and I had to go manually override that screen for each one. Unacceptable.
Looks like Google is the responsible one, not Firefox. Don’t shoot the messenger.
Why is firefox trusting the evil empire to tell it what sites are safe?
Don’t have the funding to themselves, and probably worth it so new users don’t get fucked
You can just disable Google Safe Browsing in the settings.
Set up google search console for that domain, then it will tell you why it’s blocked. It might be a false positive you can flag, or it might be that a host or service has been compromised or contains something harmful. Google’s blocklist is quite aggressive and often blocks entire domains if one of their subdomains has a violation.
