And once again Mozilla managed to break with Firefox CSS scripts! (V131.x) The one thing that guaranteed always works with every update is that something doesn't work! The constant updates and the resulting "verschlimmbessern" until nothing works in a more. With every update there is another plug-in that doesn't work or has not been updated anymore as well.

V 130.x Outkick.com page does not load only a little bit of unformatted text. Foxweather.com images are huge page doesn't load completely. PG&E.com does not load billing information, blank page. Just to mention a few...

I have stopped recommending my clients Firefox I will no longer install it.

Is that CSS script by default in Firefox or was that a custom load?

This usually happens if you have content blocking extensions that block essential CSS files.

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock,NoScript,DuckDuckGo PE,Disconnect,Ghostery,uBlock Origin,Malwarebytes), always make sure such extensions do not block content.

You can try these steps in case of issues with webpages:

You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.

  • hold down the Shift key and left-click the Reload button
  • press "Ctrl+F5" or press "Ctrl+Shift+R" (Windows,Linux)
  • press "Command+Shift+R" (Mac)

Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings), click the padlock icon (Clear cookies and site data) for the domain in the selected tab.

"Remove the Cookies" for websites that cause problems:

  • Settings -> Privacy & Security
    Cookies and Site Data: "Manage Data"

"Clear the Cache":

  • Settings -> Privacy & Security
    Cookies and Site Data -> Clear Data -> [X] Cached Web Content -> Clear

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

  • switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click "Refresh Firefox" in the Troubleshoot Mode start window

You can check for issues with Enhanced Tracking Protection and Total Cookie Protection. Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

  • click the shield icon for more detail and possibly disable the protection

You can check the Web Console for relevant-looking messages like about blocked content.
