After installing Firefox on my Dell Latitude E6520 with Windows 7 Enterprise NL x64, Firefox start extremely slow en shows a strange lay-out. All caracters seems like hex numers. I tried starting FF with admin rights, as administrator... no difference. But when I run FF as a domain admin (system is member of a Windows domain) it looks good. Still slow start-up.

Look here for a screenshoot: http://twitpic.com/6iq6pi

Try to set the pref gfx.font_rendering.directwrite.use_gdi_table_loading to false on the about:config page.

If that doesn't help then try to disable some other gfx.* prefs

You can also do a font test to see if that helps to identify the font that is causing it.


To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.

  • Use the Filter bar at to top of the about:config page to locate a preference more easily.
  • Preferences that have been modified show as bold(user set).
  • Preferences can be reset to the default or changed via the right-click context menu.
