Steps to replicate? Can we access the same file? X11 or Wayland? What desktop? Do you have the same issue with Firefox in Troubleshoot Mode?

Try downloading Firefox from Mozilla. Download, unzip, and run firefox-bin from the folder and see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

Hmm, do you use any custom CSS (userContent.css or userChrome.css file)?
