I installed IE9 in June of 2011, because I had to. I needed it to test web apps. I've had nothing but grief with IE9. Web apps don't work in IE9, because when web apps were born, the world was in IE6. IE6 have nothing but contempt for Internet standards, yet had the most users. So the world produced web apps that still need IE6. IE is holding the world back. I'm glad I don't have to test web apps anymore. (Note: Google Web Toolkit do not work well with IE, says it does but it certainly does not.)
IE9 came with F12 emulation modes that
do not work. Now who thinks it's a good idea to hide that behind F12?
Firefox
was great for several years, many people had enough IE fail-ness and went to Firefox, until they got jealous of new comer Chrome and decide to go
nuts with version numbers. It provoked me enough with endless annoying updates that I fired Firefox. I don't use it unless I have to.
I uninstalled IE9 today because IE9's emulators just do not work. It is possible to uninstall, join me and uninstall IE9. You don't need it.
F12 to set non-working emulators? Where are my menus?
IE9 does not make the web more beautiful. It is not any better than IE8, and many web apps do not work with IE9.
Also, I have hotmail, yahoo and gmail. Hotmail is consistently the worst - sluggish and awkward. I had a preview of Windows 8 and the tiles are just awful. I am worried about Microsoft.
The world is really starting to go with Apple.
