When I opened Firefox yesterday, it was updated and then opened fine. Today, I get an error message that file plds4.dll can not be found & the application does not open. I found a file plds4.dll.moz-backup in my Mozilla firefox folder, but no plds4.dll file. Do I download a whole new Firefox installation file or can you send just the missing file?

Solved my own problem. Downloaded and ran a new version of Firefox, and the missing file is now in the Mozilla Firefox folder. Firefox is running well. I hope that this helps someone else.
