Just FYI, we did land a patch for May's 52.8.0 release which may help with some of the safebrowsing-related slowdowns. Obviously we can't promise that it'll be a silver bullet for all performance issues people are seeing, but hopefully it at least serves as a mitigation for some. If you're interested in trying out a build containing the fix, feel free to reply to me (off list please) and I can send you links.
