screenshots added... initial post seems to have ignored them.

Type about:preferences#content<enter> in the address bar. Across from fonts and colors, press the Advanced button. On the bottom, turn on Allow Web Sites To Choose Their Own.

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options) key, and then starting Firefox. Is the problem still there?

As stated in the opening post websites are already allowed to choose their own fonts.

Sadly opening Firefox in Safe-mode did not help either.

Unrelated to your post: Setting windows ClearType Option helped a bit, but it's still pretty messy.

I've called the big guys to help you. Good luck.

Is ClearType enabled in Windows?

• Anti-Aliasing Tuner: https://addons.mozilla.org/firefox/addon/anti-aliasing-tuner/

@cor-el, ClearType is enabled (as stated earlier) and helps a bit, but there are still Rendering Problems left, e.g. an 'e' missing the horizontal line. I installed Anti-Alising Tuner just now, it either does not help, or my settings are messed up (tried some out, none got results...).

@guigs2, here's the troubleshoot:

Thanks everyone for using their time on my problem :)

PS: The picture shows how the formerly posted site looks after enabling ClearType. You can now see the '+', but there are still problems, most obvious with 'a' and 'e'.

Hi there,

as the problem still exists to this day, does anyone have any more suggestions on what to do about it?

Greetings.

gfx.downloadable_fonts.woff2.enabled set to true?

Corel might FSBE also be running into Bug 119490 ?

What font is used to display the text?

You can right-click the text and select "Inspect Element" to open the Inspector (Firefox/Tools > Web Developer) with this element selected. You can check the font used for selected text in the Font tab in the right pane of the Inspector. Inspector

@guigs, gfx.downloadable_fonts.woff2.enabled is set to true

@ cor-el, the font is called Open Sans: http://fonts.gstatic.com/s/opensans/v13/cJZKeOuBrn4kERxqtaUH3ZBw1xU1rKptJj_0jans920.woff2 @font-face {
