Internet Explorer - Critical Fix

[Seesee]

Seems I'm just plain stupid as I've been using IE and Outlook for 3 years and never a had a glitch that I can recall

However, rather than still be stupid ..I have just changed over to Firefox for browser and email and have found no difference in speed or efficiecy so far. But, my text now looks slightly different, not quite as bold or easy to read ???...any thoughts on that quirk, it's bugging me !


Just noticed as well my emails are still coming through outlook but I've marked that off as not my default server.....do I have to somehow completely uninstall Outlook to stop this ?


Also just noticed my Opanda Exif reader program no longer works ?...remedy please
