When I upgraded to the new Firefox, I'm getting an error message "Invalid URL" on some websites. How do I fix this? I tried searching, but what I found wanted me to change my anti-virus software setting. I'm not running an anti-virus.

I have a Macbook Pro that is running OS X. These websites will load on other computers with OS X running the previous version of Firefox.
