All text on WebUI is in italics on 1 browser

[reilandeubank]

I'm somewhat confused what could even be the issue with this, but the Jellyfin WebUI is showing completely in italics, but only on Firefox on my desktop. The text displays normally on Chrome on the same computer, and on Firefox on my Android phone.

Here is the dashboard of Jellyfin on Firefox:
   

Here is Jellyfin on Chrome:
   

Here is a different website on Firefox:
   


I am running Jellyfin 10.10.3 through Docker on TrueNAS Scale, and the 'Ultrachromic' skin from Skin Manager

Yes, I do run uBlock Origin, but I've already shut it off, deleted cookies, and even reinstalled FF (and made sure to delete ~/.mozilla).

I'm getting the same issue with Jellyfin 10.10.3 running on Firefox 134.0.1 on Fedora Workstation 41. The font looks like to be italic everywhere:

I normally use Chromium, but Firefox 134.0.1 in PopOS 22.04 doesn't have this issue.

Is your Jellyfin the only site with different fonts? Or does this problem extend to other sites?

Do you have custom CSS that would change the fonts?

Yep Jellyfin seems to be the only one affected... no custom CSSs loaded, did a fresh install some days ago and since opening in the browser it has the italic font issue.

Same here.  Threw me off.  Looks odd.

It looks like Firefox on Fedora is loading in an italic version of Noto Sans, despite Noto Sans in other programs not being italic (ie, LibreOffice).



I fixed it by adding this to the custom CSS, removing the first broken Noto Sans:

Code:

html {
    font-family: Noto Sans HK,Noto Sans JP,Noto Sans KR,Noto Sans SC,Noto Sans TC,sans-serif;
}

This fixes most groups within the UI, except the administration sidebar; it's much less noticeable, though.

Here’s the bug report for this issue. It was closed with a fix pending for Firefox 136.
