Apple refusing to allow addons in their Webkit
Apple's browser's name is Safari. WebKit is the rendering engine.
recognized only by Internet Explorer
So IE is the only browser that cares about your privacy and doesn't store sensitive data in its cache. Got that. I just wish that more browsers would be like IE. But after all, Microsoft has always greatly cared your privacy - unlike Google and their snooping does.
If you're not careful, you're going to catch something.
