It has always been switched on.

ok, this is strange because this would suggest otherwise:

gfx.direct2d.disabled: true layers.acceleration.disabled: true

could you go into about:config and toggle those preferences to false?

Sorry, I guess I should be answering your questions on the computer that this has historically been happening on. The computer it's been happening on has always had that box checked. I have that box unchecked on this computer at the moment while I'm diagnosing graphical/textual problems.

Firefox and all its settings on both computers is nearly identical. I have one extra add-on though on the computer this happens on: No-Script.

I had assumed it wouldn't matter because I was assuming the problem would also happen on this computer. But I have not yet tested that theory.

ok, then i'd be interested in the graphics section of about:support from that one machine where the issue is actually occurring...

Note that setting gfx.downloadable_fonts.enabled = false can make Firefox display a little box with hex codes in cases where a website is using a special icon font.

Changing this setting to true has solved the problem in my other thread. Thank you.

I do not yet know if the problem discussed in this thread has been fixed; time will tell.
