I thought that was the same for most browsers though. Usually for update checks & the like. Not all phone-homes are necessarily malicious. I've used it on & off since it was released. It does indeed have bug-free periods occasionally. I think that its internal adblocker (ini file) is excellent. Unfortunately it is impossible to just switch on & off. Plus, unlike Chrome, you can actually totally uninstall Iron from your computer. AFAIK this can't really be done easily with Chrome. Unless you have a Ph.D in computing or something. Jeez, where do I start? Why do I need to sign-in to Google Earth these days? Why do they want my mobile (cellular) phone number? How about this & this for a start.
