Some text is jumbled and unreadable gobbledygook

For the past few months some text on firefox is displaying as absolute nonsense (screenshots attached), while the rest will be normal. It's in websites and emails too, usually titles or text that's in a different font or color. I've tried updating firefox and tried turning off some settings suggested in other posts about similar problems but nothing works. Any help would be greatly appreciated, I'm sick of having to visit certain websites in Safari in order to read them!

Thank you!

This is usually caused by a problem with a specific font and you need to identify this font and fix this.

You can check in Font Book for font issues like corrupted and duplicate fonts. Note that you shouldn't disable "Allow pages to choose their own fonts, instead of your selections above" as this will cause issues with iconic fonts used by webpages to display small icons (you may see text labels instead of icons).


You can right-click and select "Inspect" to open the built-in Inspector with this element selected.

You can check in the Rules tab in the right panel in the Inspector what font-family is used for selected text. You can check in the Fonts tab in the right panel in the Inspector what font is actually used because Firefox might be using a different font than specified by the website.
