Running this PC with MS Windows XP everithing works fine (Firefox too), but if I try to execute firefox after a clean linux installation, the program crash. I tried with the following distros: Knoppix 5.01 (live CD), Ububtu 6.06 LTS (both live and install with latest patches/updates), Fedora Core 3 and Fedora Core 4. I got this problem even if I try to create a virtual machine with Linux under VmWare. The only PC I experienced this problem is equipped with the following CPU (I got the output from cpu-z 1.37) Name .........: AMD Athlon Code Name ....: Thunderbird Brand ID .....: Package ......: Socket A (462) Technology ...: 0.18um Voltage ......: 3.038 v Specification : AMD Athlon(tm) Processor Family .......: 6 Model ........: 4 Stepping .....: 4 Ext. Family ..: 7 Ext. Model ...: 4 Revision .....: A9 Instructions .: MMX(+), 3DNow!(+) Last try I made, is to debug this crash under a VmWare virtual machine running Ubuntu 6.06LTS with latest updates. I follow the instructions found there https://wiki.ubuntu.com/DebuggingFirefox, and this is the output I got from debugger: workstation@Ubuntu:~$ firefox -g 2>&1 | tee gdb-firefox.log GNU gdb 6.4-debian Copyright 2005 Free Software Foundation, Inc.

Reproducible: Always Steps to Reproduce: 1.install a clean linux ubuntu 6.06lts on a pc equipped with athlon thunderbird cpu 2.try to execute firefox from bash console Actual Results: you got a segmentation fault error and firefox doesn't start Expected Results: firefox starting As I said before, I suppose the crash is because of my CPU (maybe some kind of optimization my CPU doesn't like). I know this kind of CPU is not easy to retrieve to perform needed tests, but I'll be very happy to give my support for every kind of needed tests.
Next time it happens, can you try getting a stacktrace using the steps outlined here: http://kb.mozillazine.org/Getting_a_stacktrace_with_gdb ?
