Hi Andy, A long time ago it was necessary to uncheck this item in order to force Firefox to don't use Direct3D even on Windows Vista and newer, which prevented to use JAWS cursor. It was not related to JAWS Virtual PC Cursor support. Problems with Firefox 57 and newer with JAWS are not related to hardware acceleration, but to the fact by default Firefox 57 and newer use a different process for each tab, and unlike Chrome the infrastructure for transferring content of different processes to asistive technologies is not as accurate.
Regarding hardware acceleration, it unloads a bit the CPU by processing media content like videos and games in the GPU (the graphics card or video adapter) instead of the CPU or processor. This is especially convenient on slow CPUs like the ones of low end netbook computers or some older ones, but perhaps more power consumming and not as useful on more powerful CPUs. Anyway, I always prefer to turn this on in order to leave CPU free for most other programs which don't specifically support GPU processing. Hope it helps! 2018-05-29 16:42 GMT-03:00 Andy Baracco <w...@socal.rr.com>: > There was a time when we were told to uncheck those items, but I do not > know if this still holds true. > > Andy > > ----- Original Message ----- From: "Cristóbal" <crismuno...@gmail.com> > To: <jaws-users-list@jaws-users.com> > Sent: Tuesday, May 29, 2018 9:29 AM > Subject: [JAWS-Users] Question on Firefox 60.0.1 settings > > > Hello list, > > I was poking around Firefox after reupgrading to V 60.0.1 and going through > the various settings to make sure everything is how I want it and came > across the below: > > Use hardware acceleration when available Alt+Shift+r > > Use autoscrolling Alt+Shift+a > > Use smooth scrolling Alt+Shift+m > > So, since I rarely ever deal with these particular settings, I forgot what > is advised.
