Firefox will no longer display Unicode symbols after update?

I am using Firefox on Mac OS X Mountain Lion. Just about two Firefox updates ago (roughly Firefox 14), Unicode symbols suddenly stopped displaying that had been displaying fine—switching to boxes with numbers in them.

I have changed my Encoding options to include every single form of Unicode available to me; I am not sure if that has any effect. (Screenshot here: http://puu.sh/QcF6 ) The best part? After doing so, restarting the browser makes the Unicode symbols appear again! No more boxes with numbers! Fixed, right?

Nope! When I come back to that page a week later, they are numbers in a box again. In fact, in some cases, the symbol will display temporarily (say, if I had saved it into a blog page), then when I go to edit that blog page, the symbol immediately switches back to box-with-numbers.

This is driving me mad, and was not previously an issue. What can I do to fix this?

Did you try to restart the font server?

You can do a check for corrupted and duplicate fonts and other font issues:

Sorry for the late reply, I was waiting for the issue to re-occur. I have cleared and checked for damaged fonts, to no avail; the problem still exists. :(

Edit: In addition, I've just checked in both Chrome and Safari, and the Unicode symbol that I'm attempting to display are working fine in both of those browsers.
