Firefox caching to NFS mounted home directories killing disk IO on file server

[Donaldson Jeffrey]

Manu,

Thank you for the reply. I extracted the omni.jar with jar -x -f 
omni.jar in the /usr/lib/firefox-7.0.1 directory. This created the 
grepref.js file. I edited that file to comment out the config.obscure 
value with // and then added at the end of the file the 
pref("general.config.filename", "firefox.cfg"); then wrote the changes. 
Next, I ran jar -f omni.jar -u grepref.js. Finally, I deleted the 
.mozilla file from a student's home directory and launched firefox 
against their account. Firefox came up okay (although no homepage) but I 
checked about:cache and about:config and it still isn't pulling the 
locked prefs from the firefox.cfg file in /usr/lib/firefox-7.0.1/. Not 
sure what else to try. Any help is appreciated.

Regards,
Jeff
