firefox stops reading syspref.js after encountering non-existent setting

[Jan Groenewald]

Ubuntu 14.04 up to date 64bit, firefox 36

We had a non-existent setting in /etc/firefox/syspref.js. Firefox ignored the rest of the file until we commented it out. This is probably a bug. (FYI, this is a computer lab environment with network filesystem and disk space quotas.)

// Mandatory settings
lockPref("browser.cache.disk.capacity", 0);
//lockpref("browser.cache.disk.smart_size_cached_value", 0); // non-existent settings cause firefox to stop reading the rest of this file zomgwtfbbq
lockPref("browser.cache.disk.smart_size.enabled", false);
lockPref("browser.cache.disk.enable", false);
lockPref("browser.cache.offline.enable", false);
lockPref("privacy.clearOnShutdown.cache", true);

Better behaviour might be to ignore that line but continue reading the file, or to throw a tantrum^H^H^H^H^Herror.

Jan,

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time. Your problem may have been fixed with some of the updates.

It would help us a lot if you could test on a currently supported Ubuntu version. When you test it and it is still an issue, kindly upload the updated logs by running only once in a terminal:

apport-collect 1436207

and add any additional information that you think relevant. Alternatively, please confirm that this is no longer a problem and that we can the report. If we do not hear from you this bug report will expire in approximately 60 days time.

Thank you again for helping make Ubuntu better.
