Wasn't there some google cookie in firefox that couldn't be deleted at some point, related to safe browsing?
Then when people kept complaining they just hid it from the UI?
I honestly don't know what the situation is now though.
Guess what Mozilla's response is when Google lists something they shouldn't? "Take it up with Google". And you think Google supports those who they defame better than their usual customers? No. This is not a hypothetical scenario.
