I get a very odd Entry Point Not Found message when wanting to launch Firefox.
When I try to launch Firefox (from desktop, taskbar, start menu) I get this error message:
The procedure entry point ?NotifyDidPaint@js@@YAXPAUJSContext@@@Z could not be located in the dynamic link library mozjs.dll
Firefox worked fine on my laptop last night, this morning it just wouldn't work. And I didn't turn it off or anything. Can anyone help me?

do you know if the update to firefox 13 was applied over night - if so please try redownloading the full setup file at getfirefox.com, restart the pc & then run the installer on top of your current installation...
This didn't help, unfortunatly.. When I try to run the setup file, it asks if I ant to run as current user or as Administrator. I am the Administrator though, and no account on this laptop has a password. But when I run it as current user, nothing happens. I tried to run the uninstall but the exact same thing happens.. nothing.
I've also noticed that if I try starting the game League of Legends, I get the exact same error message when I attempt to log in. If that helps at all.
Do a clean (re)install and delete the Firefox program folder (C:\Program Files\Mozilla Firefox\).
Download a fresh Firefox copy and save the file to the desktop.
- Firefox 13.0.x: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible.
- Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will also lose your personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
- It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.
