I am running Firefox 24 on a relatively new 64-bit laptop with Windows 8 Pro. I initially installed Firefox Nightly on it to take advantage of the 64 capability.

Related or not, I started getting these error messages at startup pertaining to problems with update.exe, nss3.dll missing as well as mozglue.dll. In addition, when my laptop has been idle for some time and I want to use it its frozen (not always) and I have to reboot 'brute force'. There is also another error message that pops up from time to time being 'runtime error 216 at ...'

As it seems that mozglue.dll is associated with Firefox alone, I imagine that resolution should at least in part be found here.

I have already deinstalled Firefox and Nightly completely and downloaded and installed the current 24.o version.

I have also scanned for malware and viruses using an the present, up-to-date Windows Defender.

Unfortunately problems persist. Can any one help me?

Please ignore messagebot, unless your account was affected.

Certain Firefox problems can be solved by performing a Clean reinstall. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:

Note: You might want to print these steps or view them in another browser.

  1. Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
  2. After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
  3. Delete the Firefox installation folder, which is located in one of these locations, by default:
    • Windows:
      • C:\Program Files\Mozilla Firefox
      • C:\Program Files (x86)\Mozilla Firefox
    • Mac: Delete Firefox from the Applications folder.
    • Linux: If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see Install Firefox on Linux. If you downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
  4. Now, go ahead and reinstall Firefox:
    1. Double-click the downloaded installation file and go through the steps of the installation wizard.
    2. Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

Please report back to see if this helped you!

Thank you.

Which security software (firewall, anti-virus) do you have?

If you keep having problems then try to disable your security software temporarily during the installation of Firefox.
