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
