Come on, people, let's keep it real.  IE is NOT the only known vector for
virus proliferation.  Firefox/Mozilla have plenty of exploits as well.
Obviously they get better with each release, but here's a list from July of
2005, with release 1.0.4 (not that old of a release):

http://www.frsirt.com/english/advisories/2005/1075

Twelve vulnerabilities were identified in Mozilla Suite and Firefox, which
may be exploited by malicious web sites to execute arbitrary commands or
conduct spoofing and cross site scripting attacks. 

- An improper cloning of base objects could allow web content scripts to
walk up the prototype chain to get to a privileged object, which could be
exploited by attackers to execute arbitrary code.

- An input validation error in the processing of XHTML documents containing
fake <IMG> elements could be exploited by malicious web sites to execute
scripting code with elevated "chrome" privileges.

- JavaScript dialog boxes do not display or include their origin, which
allows a new window to open e.g. a prompt dialog box, which appears to be
from a trusted site. See : FrSIRT/ADV-2005-0820 

- An input validation error in the processing of javascript URLs opened by
media players could be exploited by attackers to execute arbitrary code.

- An error in the processing of "top.focus()" calls could be exploited by
attackers to conduct spoofing and/or cross site scripting attacks.

- A regression error could be exploited by attackers to inject arbitrary
JavaScript code from one page into the frameset of another site.

- An input validation error in the "InstallVersion.compareTo()" function
when handling specially crafted objects could be exploited by attackers to
run arbitrary code or conduct denial of service attacks.

- An input validation error in the processing of "data:" URLs could be
exploited by attackers to conduct cross site scripting attacks.

- An error in the "InstallTrigger.install()" method could be exploited to
conduct cross site scripting attacks.

- An error when handling Wallpapers could be exploited by attackers to run
arbitary code on a vulnerable system by convincing a user to use the "Set As
Wallpaper" context menu item on a specially crafted image.

- Scripts in XBL controls from web content are run even when Javascript was
disabled.

- An error in the browser UI when handling user/synthetic events could be
exploited by attackers to execute arbitrary code.

------------

Sure it's an older release, but those are some pretty nasty flaws.
