Comment(by cypherpunks):

 I've also noticed this.  A couple pages you could check are the BBC
 Iplayer and also on Ixquick, but only after you get search results and
 then click in the search box again to modify the search terms and suddenly
 those terms change font.  I haven't customized anything font-related.
 Replying to [comment:2 mikeperry]:
 > Quite possibly, yes.. Checking git tags reveals that while the font
 patch was present in 2.2.35-8, we didn't set limits for it until 2.2.35-9.
 >
 > The good news is that this means the patch is not at fault, just the
 limits we chose.
 >
 > The limits are in about:config prefs browser.display.max_font_count and
 browser.display.max_font_attempts, set at 5 and 10 respectively.

 > It is odd that this limit might affect the default font, though...
 Perhaps this is another case of our patches applying not just to the
 content window, but to the chrome as well (like #4795)?

 > The zeroth thing to find out is a test page that we can clearly witness
 the behavior.
 > The first thing to find out is if the user has set any other custom
 prefs wrt fonts.
 > The second thing is to find out if raising the limit changes things, and
 at what point.
