this should be fixed with either 1.6b or latest Firebird + XFT (which you can try
easily since it's a simple tarball, no deps needed):

Possibly dupe of bug 213734.

If still crashing, can you get a stack and attach it via "create a new attachment" ?

http://www.mozilla.org/unix/debugging-faq.html

if you're using the standard mozilla startup script, just do
% mozilla -g -d gdb
(gdb) run
[wait for mozilla to crash]
(gdb) bt
(attach the output from "bt" here)

do you have Microsoft .fon fonts in your fonts directories ? Does deleting (or
archiving) them prevent from crashing ?
Otherwise, do you have non-readable (with current user) TTF fonts ?

do you crash with 1.7rc2 ?

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that

highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce

copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.

Tested on Firefox 1.5 Beta 1, working great.
