I have been experiencing strange font rendering in Firefox on Ubuntu for the last couple of months. The letters in certain texts have very wide spacing (see the screenshot). It started on 21.10 a couple of months ago and continued after I have recently upgraded to 22.04. In Chrome font rendering is fine. So it looks like a Firefox issue.

Try refreshing your font cache. Delete the current font cache:

  • For Firefox installed as a snap: 
      rm -rf ~/snap/chromium/common/.cache/fontconfig/
  • For regular applications 
      rm -rf ~/.cache/fontconfig

Then refresh the cache

fc-cache -r -v

I had a similar issue as well; neither the font cache refreshing nor installing another font set helped. For me, the issue was a bug in the Firefox snap on Ubuntu. A fix has been committed a few days ago; more info and a workaround can be found here: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1971608

Here's the workaround they suggest until the fix is deployed:

$ mkdir ~/snap/firefox/current/.config/fontconfig/conf.d
$ cp /etc/fonts/conf.d/* ~/snap/firefox/current/.config/fontconfig/conf.d

This is an issue with the snap version of firefox. Uninstalling the snap version and installing the apt version fixes this problem.

A tutorial for Ubuntu 22.04 can be found here: How to install Firefox as a traditional deb package (without snap) in Ubuntu 22.04 (jammy)
