Downloaded the latest version from Mozilla website but Horizontal scroll bar still missing for certain url

The horizontal scroll bars had been missing for certain URL in firefox since mid last year 2023. I just downloaded the latest version for windows 11 and it is still missing.

I have checked the settings > General > browsing > related to scrollbars and they are all checked, namely: - use autoscrolling - use smooth scrolling

But it is still missing! I generally use firefox for my work and Google chrome for my personal use - to compartmentalize my browsing content/history. Now I will have to ditch firefox and use chrome only for both work and personal if this is not fixed.

Testcase? Steps to reproduce?

Can you post a link to a publicly accessible page (i.e. no authentication or signing on required)?

Can you scroll such a page with the mouse scroll wheel?


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You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.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