#### JavaScript / ReferenceError: b is not defined

I get that whenever I close a window in Firefox on my Mac. The only option is "OK", and that closes out normally. Why is this?

Have you installed a new plug-in recently? Perhaps it is more compatible with another operating system, (e.g. 'b' might not be internally defined), you could try running Firefox in Safe Mode and temporarily choosing the 'Disable all add-ons' option.

I have a few incompatible add-ons (I got rid of them and it did nothing), but other than that, my plugins are fine.
EDIT: I'm running a Mac, and that apparently means Firefox doesn't have a Safe Mode. It has Private Browsing and the option to work offline (probably wouldn't make a difference), but that's it.
