frequently, users configure their about:config for privacy or minimalism
settings such as disabling dom storage can cause websites to stop working.
what are some common or uncommon about:config settings that can be toggled to fix a website if it is acting dysfunctional?
A good way to get minor breakage on a lot of websites is disabling
gfx.downloadable_fonts.enabled. This controls font downloading which is often used for icon fonts. While icon fonts are not recommended anymore there are still a huge number of sites that use them. You’ll end up with either text versions that don’t fit like they are supposed to for ligature-based icon fonts or missing character symbols for fonts that use characters from a reserved range.But hey, I like my system fonts.
