Anyone know how to fix this.  A known problem sometimes.  Only been able to find a fix for Windows. 

 

Could you be a bit more precise? What the problem is for example. 

Netscape.cfg/AutoConfig failed. Please contact your system administrator.
 Error: pref failed: [Exception... "Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch.setStringPref]"  nsresult: "0x8000ffff (NS_ERROR_UNEXPECTED)"  location: "JS frame :: prefcalls.js :: pref :: line 33"  data: no

 

Mostly just annoying, respond to this message Firefox then loads and behaves normally. 

Thought others had run into this and knew what to do.

 

I fixed this on my system by changing a line in my /etc/armbian/firefox.conf

from this:

pref("browser.cache.memory.capacity", "-1");

to this:

pref("browser.cache.memory.capacity", -1);

 

What I did was used strace on firefox to a file, grepped the file for .cfg, found a link to firefox.conf, commented out lines by binary halving until I found the right line,

and then futzed the line until firefox would start without the error.

 

Hope this helps, good luck!
