What font does Firefox use for Helvetica?
Firefox's Reader View seems to me to show a font that is similar to Helvetica. If I try to make it use only Inter, Arial, or "sans-serif", then it changes the font. What font is Firefox using instead? This also happens in Firefox forks.
If you happen to be on Linux, then it's likely one of these: https://askubuntu.com/a/1148258
Seems to be Nimbus Sans, thanks for the link!
Could it be "Fira Sans"?
The T has overhangs, and putting the Fira font page into reader view changes the font.
I don't know the answer, but the devtools inspector should work in that view too, I think. If you use it's tool that selects the element on which you have clicked, you should see the list of fonts in order of preference on the right, which is the CSS viewer. To check which one it is, you could remove fonts from the list one by one
