Hello All,

After the recent increase of Internet Browser exploits I couldn't help but
give it a quick play.
After a bit of playing I found a bug with the latest version of FireFox
which seems to work on Win2K & WinXP.

I believe the bug to be with one of the plugins but since im not a
coder/reverse enigneerer it's a bit difficult to understand what's causing
the problem.

Anyway as a quick test I attached OllyDbg to FireFox and loaded up my 'evil'
html file and followed it through and found that FireFox crashes with the
same exception on both Win2K & WinXP.

Now what I need to work out now is which part of my html file is causing the
problem.

Is there anyway way I can trace FireFox as it runs through each piece of
HTML code?

Also what other ways can I analyse the bug?

Thanks
