weird problem ever since ive installed firefox 4. The font on websites and forum pages and my gmail inbox seems to be Arial, or something similar. Checked the settings of Firefox and default font is set to Times new roman although the checkbox that says "allow pages to choose their own fonts instead of the ones above" is ticked. Also character encoding is set to unicode utf-8. I've reset settings to default to however still no joy.
Not really a major problem however rather annoying and wondering whether someone can help!

Most sites use a sans-serif font like Arial; even here! Most sites override the font, so you will need to UNCHECK that box if you do not want them to do so.
