This setting can be disabled. It sounds like it’s for sites that are exploiting vulnerabilities in extensions to install malware. Firefox already includes Google Safe Browsing to warn for malicious sites, so I’m assuming this is just another hardening mechanism to (1) mitigate damage from someone bypassing GSB and (2) allow Mozilla to take action before Google does. Rest assured, if Firefox started using this to push advertisements through or allow tracking, the community would be in UPROAR.

That’s not great.

It is amusing that you guys cannot fork the project and remove the feature, while the software is “open source”. But arguing about privacy & security & “F(L)OSS” like you are the god.
