I never said to turn it off... I said that google will get your browsing data. That said, I firmly believe that the best antivirus is common sense. Everyday use

  That's the exact point, though, Google does not get your browsing data. What Firefox does, is that it downloads a complete list of hashes from Google's Safebrowsing server. Every instance of Firefox does this every 30 minutes. Nothing identifying about this. Firefox then stores only the first 32 bits of those hashes to save on space (as the list is unsurprisingly gigantic). Then Firefox does a lookup against this locally stored list whenever it loads a webpage. If a webpage's first 32 bits should be on that list, then it obviously has to check if it's actually the complete hash that matches. But for that, it requests all hashes with same first 32 bits from Mozilla's server. They proxy the list for that purpose. So, it's at best Mozilla which can guess that you browsed to one of the many pages that share the first 32 bits of the hash. Google will have no clue about it. And in fact, they even throw in a few noise entries when requesting the full hashes from their server, so even Mozilla actually doesn't know for sure which first 32 bits you browsed to. https://feeding.cloud.geek.nz/posts/how-safe-browsing-works-in-firefox/ https://feeding.cloud.geek.nz/posts/how-safe-browsing-works-...
