Well we can all remember(I think) the days of when Firefox was but a seemingly "Underground" browser. A lot of people have switched over to Firefox because of the extensions(Although I have literally made my own ADBP for Opera, just one widget, a little fiddling and it can kick ADBP's ass any day") Now Opera is that program, and it beats Firefox with a dead fish. Well, I like Firefox, but Opera is definitely better IMO.
Well anyways, the reasons I hate IE.
1.Microshaft
2.Less secure.
3.Less customization.
4.Externally installed additions and tool bars.
5.Slower browsing.
6.It hates any non-microsoft program.
7.The name just couldn't be more original.
8.MEMORY WHORE
