On my Dell monitor display resolution 1920 x 1080, the right hand scroll bar is at times nearly impossible to see on some sites.
Is it possible to reduce the horizontal width of this display, and if so could you please tell me how?

A picture and the name of the operating system would be helpful. Also a picture of the screen settings that you have. But could also be a wrong setting at the monitor. Did you check them?

Here I don't see anything wrong. Would be helpful if you post a picture that shows the scroll bar problem.

Here are the requested pictures.

1. Scroll bar not highlighted.

2. Scroll bar highlihted, but this is in fact a good version on Aseannow.com, normally what is visual is far narrower than this, to the degree that I have trouble finding it.

I understand the problem now. Which browser are you using? 

But perhaps this helps already:

First up on looking at the Chrome equivalent, huge scroll bar in comparison, this for sure is a Firefox issue - progress.

 

The following on the recommendation on this site, has had no effect, even when I went up to 5:

 

• Use the search box to search for widget.non-native-theme.scrollbar.style preference
• Now double-click on that preference to change the scrollbar width. You can enter any number from 0 to 5. Just add a number and press the Enter key or click on the Save (Blue tick) button.

I am a total IT idiot but had a very similar problem. Mine turned out to be size. Maybe try slightly decreasing your font size. Hit control and the minus key one time and see if it appears. This works for me. Fixed it all after hours of messing around. While you are doing this you can see what percent you are on of the size.

User a bigger number say 40, you will see the scroll bar gets bigger.

 

Without changing the scrollbar size you could also try:

"widget.non-native-theme.enabled" and set it to false.

Firefox:

about:config

### for my scrollbar width

widget.non-native-theme.scrollbar.size.override 20

### for my scrollbar shape

widget.non-native-theme.scrollbar.style 1
