Cannot change xterm.js font in Firefox

[pika02]

Hello all, I'm an archlinux user and mainly use firefox browser.
I found the font in xterm.js is awful, and it doesn't change after I set the font to Noto Sans Mono.


I have tried a new firefox profile but no use.

Everything goes well in Chrome, I can freely change the font of xterm.js.
I wonder it is a firefox issue, a xterm.js issue or a PVE issue. Sorry for my bad English.

can firefox access that font with that name? did you try a different font (e.g. 'Arial')? can you check the browser javascript console (F12) for errors ?

Thank you for reply, dcsapak
I tried Arial, Hack, monospace and others but all failed on firefox. Chrome was still OK.
F12 type a ~ in xterm.js console, so I pressed Ctrl+Shift+I for devtool.
But unfortunately I don't know how to find errors

I'm sorry to say this was caused by my bad fontconfig settings
