Because un-installing it does not even work.
I'm using Windows XP pro.
I need IE to be default. I checked the setting in IE to always check to see if IE is default, but it never askes me if I want to switch, and the setting in firefox only tells me that FF is already mydefault browser. So I uninstalled Firefox. Then I clicked a hyperlink in an email and was asked for the path to a browser to open the link. I selected IE, and the link opened in IE. I clicked several links then and they all opened in IE.
Then I re-installed FF, and now FF is default again. Not only did FF take over default browser, but it never lost any settings. I have a manual proxy configuration set, and even though I uninstalled it, when I re-installed, all my configurations remained the same.
I just love it when you un-install something and it does not really uninstall. I have had nothing but trouble with FF. My list of grievances is long. It constantly tells me SSL is disabled even though it is fricking enabled is my biggest gripe. I cannot get to secure sites. But if I could just make IE default again I would be a little happy.
If I could I would shit can this piece of demon spawn crap called Firefox. But I need it for some work stuff.
