It's possible. It's far more possible if you enable
javascript. A lot of sites won't entirely work without
it, but it's also the root of almost all browser
vulnerabilities, and many of those include the
ability to crash IE.
I've seen Firefox cause a *reboot* on some sites,
even with script disabled. It seems to be fixed now,
but I never figured out the cause. Nevertheless, I
was able to repeat the problem on particular sites at
the time.
I've also seen another very odd problem with
Firefox: I have local PHP webpages that are a webpage
missing a block of code that gets inserted by the server,
depending on the browser. So in other words, these
are normal webpages with a chunk removed. If I open
those pages with Firefox it goes crazy, opening window
after window until I call up Taskmon and kill Firefox. Yet
IE handles them fine.
For similar fun with IE, try saving the following line
in Notepad and save as an HTML file. Then open it in IE:
<style>*{position:relative}</style><table><input>
I don't know about IE7, but with IE5 and 6 it will crash
IE. On my system it also takes down Windows Explorer!
Webpages are extremely complex. It's not surprising
that some odd quirks pop up occasionally. (I'd agree with
Alais, though. Both IE and Firefox have bugs, but there's
no reason to use IE. By virtually any measure it's worse
than Fiorefox and Opera. ... Except when it comes to
rendering microsoft.com webpages.
