Scroll Bar too Thin

more options

I have used firefox for a long time , however, if I can't fix the tiny width of the scroll bar soon I will have to migrage to another browser which I don't want......I have tried the About.config route...and that hasn't worked . Tried several times....so not sure what I can do to increase the width of the scroll bar. HELP! Thank you for any assistance.

Hi Larry, what did you change in about:config?

Firefox is trying to follow the new disappearing/overlay scroll bar style of Windows 11. If you want to globally change the Windows setting, you can take a look at

System Settings > Accessibility > Visual Effects > Always show scrollbars

If you prefer to make a change only in Firefox, you can try this:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

More info on about:config: Configuration Editor for Firefox. The moderators would like us to remind you that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future.

Disable disappearing overlay-style scroll bars:

(2) In the search box in the page, type or paste widget.windows.overlay-scrollbars.enabled and pause while the list is filtered

(3) Double-click the preference to switch the value from true to false

If the scroll bars are still not wide enough on some pages:

(4) In the search box in the page, type or paste layout.css.scrollbar-width-thin.disabled and pause while the list is filtered

(5) Double-click the preference to switch the value from false (allows sites to modify) to true (sites cannot modify)

To switch from Windows 11 style to Windows 10 style (not sure whether this makes a difference):

(6) In the search box in the page, type or paste widget.non-native-theme.scrollbar.style and pause while the list is filtered

(7) Double-click the preference to display an editing field, and change the value to 4 then press Enter or click the blue check mark button to save the change. For reference, the values mean the following, but I don't know which ones work on Windows:

  • 0 => use your OS default style
  • 1 => use macOS style
  • 2 => use GTK style
  • 3 => use Android style
  • 4 => use Windows 10 style
  • 5 => use Windows 11 style

Does some combination of those give you the width you need?
