Problem description: Upon launch of FF, message is displayed and FF fails to launch
Solution: Wiped out Firefox and installed from scratch. Resolved message/problem.
Problem returned: Had to end Firefox process instead of closing properly. Message/problem returned.
Solution: Removed some files in FF installation directory (instead of stupid reinstall) and resolved.
Problem returned again!!!
Did you create a mozilla.cfg file in the Firefox program folder to initialize prefs.?
You get this error when you specific using mozilla.cfg, but Firefox finds that there is a problem with the file or the file is missing. Make sure that mozilla.cfg doesn't have a hidden .txt file extension appended (mozilla.cfg.txt).
See also Configuration:
Can you please post the content of mozilla.cfg if the above didn't help?
Below are the content of .cfg and .js files.
Mozilla.cfg file: // lockPref("network.proxy.type", 5);
local-settings.js pref("general.config.obscure_value", 0); pref("general.config.filename", "mozilla.cfg");
If the name all lowercase: mozilla.cfg and is the file located in the main profile folder and not in the same location as local-settings.js?
- (64-bit Firefox) "C:\Program Files\Mozilla Firefox\"
- (32-bit Firefox) "C:\Program Files (x86)\Mozilla Firefox\"
Note that best is to start local-settings.js as well with a comment line (//).
You can check the Browser Console immediately after starting Firefox for error messages.
- "3-bar" menu button or Tools -> Web Developer
