Hi everyone,

I'm experiencing an issue with my website's compatibility with Firefox. website My website, which provides online educational resources and tools, is not displaying certain interactive elements correctly when accessed through Firefox. These elements work perfectly in other browsers like Chrome and Safari.

Specifically, I've noticed that some JavaScript-based interactive features, like quizzes and drag-and-drop activities, either don't load or don't function as expected. I've already cleared the cache and ensured that Firefox is updated to the latest version, but the problem persists.

Has anyone else encountered similar issues, or does anyone have suggestions on how to troubleshoot and resolve this compatibility problem? Any insights would be greatly appreciated!

Thank you, fatemahx

Show the issue. You did provide a link, but failed to provide steps to replicate and screenshots comparing Firefox to other browsers. Also, what version of Firefox are you running?

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, DuckDuckGo PE, Disconnect, Ghostery, Privacy Badger, uBlock Origin), 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You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.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 the "Refresh Firefox" button on the Troubleshoot Mode start window

You can check for issues with Enhanced Tracking 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.
