Hello,

Uninstall Firefox from the Windows Control Panel > Programs and Features, and delete the Firefox folder from your Program Files as well:

• C:\Program Files (x86)\Mozilla Firefox ; or
• C:\Program Files\Mozilla Firefox

Reinstalling Firefox after downloading a fresh copy from the official Mozilla servers:

• https://www.mozilla.org/en-US/firefox/new/
• (or if you need a different locale) https://www.mozilla.org/en-US/firefox/all/

I've tried uninstalling completely and deleting all folders inside Program Files using the automatic installer as well as the offline installer. I tried using the XULRunner nss3.dll but it does not include all necessary functions to run Firefox.

The clean reinstall persists the issue which makes me think there may be an issue with the final nss3.dll binary.

You can check the source code or ask advice via IRC.

Well...I see inside pk11pub.h that the prototype exists for PK11_PubDerive(). The function is written in pk11skey.c.

Now is it compiled and working properly in the final binary?? I'm no developer so I can't verify this.. any help would be appreciated.
