Title. I've tried reinstalling the Arial font and that didn't work. I only noticed it when I updated to 17, so that must've been it. It is really annoying. How can I fix this?
Try to set the gfx.content.azure.enabled pref to false or if this didn't help disable Direct2D by setting the gfx.direct2d.disabled pref to true on the about:config page and leave hardware acceleration otherwise enabled.
This can be a problem with the font that is used to display the text.
You can use this extension to see which fonts are used for text that is selected (right-click context menu: Show fonts in selection).
You can do a font test to see if you can identify corrupted font(s).
You can try different default fonts and temporarily disable website fonts to test the selected default font.
Well, I tested Arial, and everything came out bold on every page I tried when I unchecked the box you described above in options. I've already reinstalled it, what do I do now? Thanks.
Did you verify that Firefox is using the regular Arial font and not a bold variant?
Does this still happen if you temporarily remove other Arial fonts?
Did you refresh the currently installed Arial font or downloaded a fresh file or restored it from the installation DVD ?
I turned off the setting that websites can choose their own font, then set my default to Arial, and everything was bold. I think that answers the first question.
How do I temporarily remove other Arial fonts?
I downloaded a fresh Arial font.
