Once I put in the new ram, I'll try Firefox 56 as well. Just sitting under Windows 10, it's using up nearly all the ram on a 1gb stick. I ordered a 2gb ram stick that arrives tomorrow, but I don't think that is going to solve the video issues.

I don't want to run XP though and am trying to figure out how to smooth out Windows 10 (if all else fails, I've no qualms to go back to Windows 7). Just for giggles, I re-installed XP and tested video with Firefox and it was smooth. I thought maybe it was the driver that MS installed or the fact that it only has 1gb of ram. It was a lot better on the OG Win 10 release. XP and Windows 7 were fine but ever since the Windows 10 Creators update, it is nearly unusable. I've had an old HP Mini 110-1025DX since 2009, I never used it all that much, but I've ran XP, Win 7, Windows 8 and Windows 10 on it. So, I'm a hoarder and keep all my working computers around to put in various places to always have internet access.
