It was too annoying that i was not getting Deja Vu Sans Condensed font for firefox itself, whereas this font is working with other applications in Gnome. I was getting Sans font instead in Firefox. After gooooogling (too long) i got a workaround for this.
Just add this lines to userChrome.css (create a new file if it is not there), create this file in ~/.mozilla/firefox/(profile)/chrome folder.
font-family: “Deja Vu Sans Condensed”;
I love this font 🙂
