Some web pages may require additional fonts to display properly.
Try installing some of the following packages if some characters
are not displayed properly:
- media-fonts/arphicfonts
- media-fonts/droid
- media-fonts/ipamonafont
- media-fonts/noto
- media-fonts/ja-ipafonts
- media-fonts/takao-fonts
- media-fonts/wqy-microhei
- media-fonts/wqy-zenhei

To fix broken icons on the Downloads page, you should install an icon
theme that covers the appropriate MIME types, and configure this as your
GTK+ icon theme.

For native file dialogs in KDE, install kde-apps/kdialog.
