Wonder if Firefox's "Block Reported Attack Sites" and "Block Reported Web Forgeries" features check with Google to determine which sites are legit and which aren't?
Now I get it. To disable
In Windows> Tools> Options
In Linux> Edit> Preferences
Under Security, uncheck “Block Reported Attack Sites” and “Block Reported Web Forgeries”.
Of course, you might not know after that when you are browsing a malicious site, but Google will be out of your business.
