Vertical scrolling glitch
About 1 in every 40 or so times that I try to drag the vertical scroll bar with my left mouse button, it acts like I have clicked UNDER the scroller and starts scrolling down quickly until I release the mouse button. This NEVER happens in Chrome or other programs. It always works properly the next time I drag it.
Potentially related: About 1 in every 75 or so times that I try to drag the vertical scroll bar with my left mouse button, the scroller doesn't stay under my mouse cursor. It moves about half as fast. This makes it impossible for me to scroll to the bottom of the page because my mouse cursor gets to the bottom before the scroller, which means I have to let go and grab the scroller again to finish scrolling down. The scroller always stays with my mouse cursor on the 2nd attempt.
I've attached a pic showing what i'm calling the "scroller"

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.
You will need to restart Firefox for this to take effect so save all work first (e.g., mail you are composing, online documents you're editing, etc.,) and then perform these steps:
In Firefox 54 and below:
Click the menu button New Fx Menu and select Options (Windows) or Preferences (Mac, Linux). Select the Advanced panel and the General tab. Uncheck Use hardware acceleration when available. Close Firefox completely and then restart Firefox to see if the problem persists.
In Firefox 55 and above:
Click the menu button New Fx Menu and select Options (Windows) or Preferences (Mac, Linux). Select the General panel. Under Performance, uncheck Use recommended performance settings. Additional settings will be displayed.

I have noticed Pluma (my text editor) has just begun having the problem now, so this might not be a Firefox issue, but the fact is Firefox hasn't messed up since I disabled the hardware acceleration setting! thank you!!
