I have Firefox on a few RHEL6 boxes that are fully updated to RHEL 6.5 and have firefox-17.0.10-1.el6_4.x86_64 installed. I don't really run local X sessions and just ssh -X user@host... and run firefox. I have a pre-existing firefox configuration that doesn't show the menu. When I try to click the menu down it won't open and firefox just freezes for a little while. Sometimes it will come back to life, and other times not. The Firefox dropdown will not open no matter what I do. I have seen this behavior 4 different RHEL boxes and it is consistant. I run firefox from the command line and I don't get any error messages or anything so I'm lost on how to troubleshoot.
On one machine I completely deleted the .mozilla directory and ran Firefox. Firefox starts ok and the menu is there... and the two default tabs open... but trying to access any of the dropdown menus does not work. It just freezes. I don't have anything odd going on. No NFS... no kerberos. No NIS/YP. Just a local account access via ssh -X.
Hm, I have no idea why it freezes. Can you try to run it from gdb and attache backtrace here? When it freezes. How-to is here - http://fedoraproject.org/wiki/Debugging_guidelines_for_Mozilla_products
Created attachment 829803 [details] crash_bt per instructions for freezing program I followed the isntructions listed here: http://fedoraproject.org/wiki/Debugging_guidelines_for_Mozilla_products ...and created a crash_bt file for a frozen program. Hopefully that'll have some info in it that is useful. Under gdb a menu would drop down but it was extremely slow and froze the program for a while.
Unfortunately the backtrace is incomplete and does not contains main firefox thread. Anyway, can you test firefox with new profile and in safe mode? (firefox -safe-mode).
Please retest with new packages (Firefox 24) for RHEL6 and reopen if you see it again. Thanks!
Yes. It is working for me now. Thanks.
