Hi,

I was working on my work on a Google Doc, and when I tried changing the font, Firefox immediately crashed after clicking the font box. When I restarted, Japanese characters turned into boxes with codes in it. I have the Japanese language installed on my system and it works fine on my system. I also have the Japanese language installed on my browser. Other characters appear as the same thing, but I don't know for sure what they are other than Chinese and Korean. My cursor also changed to what looks like a hand pointing at something whenever I hover over something, however I am unable to provide a clear screenshot of that so I can only provide pictures of the messed up Japanese characters.

How would I fix this?

System OS: Ubuntu 21.10 Firefox Version: 99.0

You can try Firefox from the official Mozilla server if you currently use a version from the repositories of your Linux distribution to see if it behaves differently.

Sounds that there are serious issues with fonts. 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 Firefox can't use this font.

The screenshot shows the location bar drop-down list. Does this also happen on website as there it is easier to check font-family rules and the Fonts tab in the Inspector ?

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.
