Numbers and characters in strange font
On some websites like Wikipedia and Nitter, the numbers and certain characters (like "quote marks") don't match the other characters. They are in a serif font and so much smaller that they are practically unreadable. I've selected "Allow pages to choose their own fonts" in settings and restarted FF but nothing has changed. This problem does not exist in other profiles but I don't want to have to switch profiles. How can I fix this? Screenshots attached.

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.
The inspectors shows all numbers, spaces and quotation marks on Wikipedia as being "Al Nile". How can I change those back to Helvetica?
