After Firefox updated today, the executable no longer starts. I get the following error message:

firefox.exe -- Bad Image

C:\Program Files\<mozilla firefox\gkcodecs.dll is either not designed to run on windows or it contains an error. error status 0x000000d. < p></mozilla>

And then another error message: Couldn't load XPCOM.

Please advise.

Where did you get Firefox from? For XPCOM, see if this helps. https://support.mozilla.org/en-US/questions/1229392 What OS? What version of Firefox?
