I have set Verdana as my display font in all circumstances and always have done with all versions of Firefox. But in this version, on CERTAIN text (e.g. on Google searches, all text beneath the link), the font displays in some 'comic' style font that is near completely illegible.

Certain parts of the webpages are fine and do display in verdana, but not sure why as there are 3 settings for fonts in preferences, serif, sans serif and monospace, but it could have nothing to do with these as they are all set to Verdana as is the default.
