Even when I lift my finger off my mouse pad the browser keeps scrolling uncontrollably.
When I press down arrow on a long page the scrolling won't stop even when I'm not touching anything. It NEVER used to do this with earlier versions. It's not even controllable, like on IE when the mouse icon comes up and lets you govern how fast, or slow it scrolls up and down.

Are you using the latest version of your mouse driver software (Control Panel > Mouse) ?
Also make sure that all mouse settings are the default.
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the Safe mode start window to disable all extensions.
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
