I-Firefox Isithangami Sokwesekwa

whenever i install fonts onto my computer, firefox changes many elements in many webpages to those fonts. this is exteremely frustrating, because i install wacky fonts, so i end up not being able to read anything… in the omnibar the font is set to what i installed 2 times ago. so right now its "EPSON 太丸ゴシック体Ｂ". heres a pic: https://i.imgur.com/aJca75i.png

but for other things like japanese, i get this https://i.imgur.com/BundcfM.png (its the font i just downloaded) if you can read japanese then ull know that its completely illegible unless if u know cursive very well inspect element for this cursive font gives `font-family: "Helvetica Neue",Helvetica,Arial,sans-serif;` and if i hover over it the popup shows the font as EPSON 太丸ゴシック体Ｂ (which it also shouldnt show…), but it actually renders the cursive font………

all my font settings in about:config are reset to default but nothing changed

please help

Hello,

I noticed a few hours ago that my Google search in Japanese was now displayed in an ugly font I have no memory of (could not identify it, attached a screenshot just in case).

I tried to change my settings for Japanese in Languages and Appearance, but no matter what, this unknown font remains the apparent default on sites such as SUMO and google.com.

I just refreshed Firefox to no avail.

Am I not looking in the right place?
