Issue with latest Firefox update -- Firefox no longer starts

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>

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

Please advise.

I re-installed Firefox (didn't manually delete anything), and this has taken care of the problem.

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?
