Without me doing anything, firefox changed the fonts (the degree of change is differenet for different sites) to something else (please see image) and I am unable to change it back.

This is a clean profile that has no addons.

I have ensured that the settings are at its default

And this problem does not affect TorBrowser which is based on firefox and also Chromium.

I am on Debian 10 (Buster, testing), firefox 59, KDE.

Solutions I tried:

  • I have checked the KDE settings for font.
  • I have almost all possible fonts installed (6GB).
  • Deleted everything in the .cache folder and ran fc-cache -rv.
  • Installed a fresh firefox-esr (v52) with new profile and no addons, and it has the same problem.


Why is this happening, and how do I solve it.

Thank you so much for reading this.

Chosen solution

SOLVED:

Renamed the /home/user/.fonts folder to .fonts-disabled. Ran fc-cache -rv Now those fonts will not be used by the system.

Problem solved - firefox now has correct fonts.

That folder had fonts that I have been collecting for 15yrs (6gb), and something there was corrupting firefox. And after getting rid of it, I realized that I don't need many fonts (just the basic ones from debian plus mscorefonts was more than enough). Even other language fonts (like japanese) are still working.
