How can anyone who is sane of mind and not an MS employee possibly advocate the usage of IE?
Your reasonings are terrible:
1) Bugs being found is surely a good thing? It means they get fixed, as opposed to the developers sitting with their fingers in their ears going "lalalalala" and not wanting to admit that there might be flaws. Also, can you not see that the speed in which bugs are found means there's a good following for Firefox and the users report things quickly. Also, the speed in which bugs get fixed and new version is released speaks volumes about the developers being on the ball.
2) Firefox is only incompatible with websites that don't adhere to web standards properly. It's far stricter that IE with code, which should really ensure that people write sites properly in the first place and don't just leave it with rubbish code that only IE can display correctly (generally cause it was written in Frontpage, but that's beside the point). If more people used FF whilst developing websites, we'd have better, stronger code and less crap.
3) Yeah, OK, FF is kinda bulky. Still, it runs better than IE for me (x86 and x64) so really can't see a downside. There aren't that many people using systems that can't handle it nowadays. A quick glance at system requirements for both browsers shows that the latest version of FF runs on lower versions of Windows than MS's own IE, and the rest of the base system requirements are the same.
And so, to my conclusion:
You sir, are wrong.
