I personally recommend against it myself. In doing so, you are sending your information to Google in a very intimate way even more so than using Chrome. Every internet transaction you do is recorded, documented, and used against a pattern database. Google is a marketing company and it thrives on being able to sell data to marketing groups and buyers. It's been in trouble several times for violation of privacy issues throughout the world. The risk to your private data is not worth the minimal reward in speed that you may obtain. (Due to location, DNS routing, etc, your speed may not even be noticeably different.)
