this is the appearance
This usually indicates that there is a problem with the font that Firefox wants to use. This is the normal ASCII range (00-9f) and not some page in another language.
You see little boxes with the hex code of the character if you do not have a font installed that covers this Unicode range or the font that is specified is corrupted.
You can right-click and select "Inspect Element" to open the builtin Inspector with this element selected. You can check the font used for selected text in the Font tab in the right pane of the Inspector.
Note that this is not about the font-family CSS rule, but about the font that Firefox actually uses as shown in the Font tab.
You can do a font test to see if you can identify corrupted font(s).
You can try different default fonts and temporarily disable website fonts to test the selected default font.

--- You can check gfx.downloadable_fonts.enabled on the about:config page and make sure it is set to true (if necessary double-click the line to toggle its value to true).
