mozilla and internet explorer.

while mozilla and netscape are safer than IE, they can't interprete a whole lot of style scripts, php-extensions etc. on my computer i have 4 different browsers installed, cause i build webpages for little companies or associations and have to check wether it all looks good in every browser. usually with IE i don't have problems at all, cause this browser can read just everything. if it was safer i would only use IE! it's also the fastest of my 4 browsers.
