Why has my font turned bold or look strange without me changing the settings?

My font on all websites seems bolder than usual, particularly noticable on sites like Wikipedia and Google. On sites like Facebook the default font appears slightly smaller and blurry. I don't recall changing my font settings and they're still set to their defaults.

Any ideas?

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

In Firefox 4 Safe mode disables extensions and disables hardware acceleration.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

If disabling hardware acceleration works then check if there is an update available for your graphics display driver.

Try to toggle some Boolean gfx.font_rendering prefs on the about:config page to disable some features and maybe set gfx.direct2d.disabled -> true to disable Direct2D.
Filter: gfx

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.
You can use the Filter bar at to top of the about:config page to locate a pref more easily.
