My firefox now is updated to 26.0.
I find my firefox can not display some icons of some english sites.
Below is my screenshot of wordpress management interface. On the left of the picture, you can find those strange characters.
What is the matter? Thanks
Turn off NoScript, or allow the javascripts which should be allowed. Or just allow the fonts for that site.
Or under Firefox->Preferences, under the Content tab click Advanced and check Allow pages to choose their own font...
