Hello
I sew on Compatibility page that there is a problem with XUL-Based apps (Firefox, Thunderbird, Sunbird, Nvu) with fonts. There is a solution to this problem, and it doesn't affect theses applications on Windows or Themes.
Open PortableApps\FirefoxPortable\Data\Profile\chrome\ . If there isn't file nammed userChrome.css, create a copy of the file UserChrome-Exemple.css and rename it UserChrome.css. Open it with a notepad and add at the end of file theses lines :
* {
font-family: "Tahoma", "Sans";
}
That makes it look better
