In response to the recent reports of the major security flaw in all modern IE versions, I have installed Firefox and imported my bookmarks and stuff to it. I have always used IE as my primary browser (and my only browser during the last year or two). I have noticed a couple of things. First, Firefox seems to load slower than IE, but uses less system memory. I also noticed a Firefox Sync option. Does that keep my bookmarks online across my desktop and tablet the same way that OneDrive does when I create a sync account? Will suspicious URL blocking by Kaspersky work the same way in Firefox? And finally, I have the Bing Bar in IE 11 which shows message notifications and current weather. Can I get that in Firefox as well? I want to know if it is safe to stay with Firefox since I've seen where there are a few corporate websites which are not compatible with it.
