I think Firefox follows your default setting for "desktop" applications in Windows ("modern" applications have their own settings). If you want to widen scrollbars for ALL desktop applications, you may be able to use the methods described on the following page:
http://winaero.com/blog/how-to-change-the-size-of-scrollbars-in-windows-10/ - show options for manually editing the Windows registry or using their utility program named WinAero Tweaker (I have not tested either method myself)
To modify only Firefox, you probably need an add-on. I didn't see anything in a quick search, but: https://addons.mozilla.org/firefox/
Also, you might be able to use a custom style rule. For example, this might still work (I copied it from a 2012 thread):
scrollbar[orient="vertical"] scrollbarbutton,
scrollbar[orient="vertical"] slider {
width: 25px !important;
height: 25px !important;
-moz-appearance: none !important;
}
You can apply custom style rules to Firefox's interface using either a userChrome.css file, or the Stylish extension, but I think the other methods might be more convenient.
