If there is a problem with scrolling the try to disable smooth scrolling:

• Tools > Options > Advanced > General: Browsing: "Use smooth scrolling"

Try to disable hardware acceleration in Firefox.

I Should have mentioned that I tried all that prior to posting, and it makes no difference. If you can make those adjustments on your computer, you'll see it makes no difference. I've tried it on 2 different computers with 2 different video cards and it shows the same jerkiness

It's an anomaly (problem?) in Firefox itself. Hoping to get the attention of someone at Firefox to make a change at the Browser level so the initial/subsequent scrolling is smooth like IE/Safari/Chrome.

Other searches with "Firefox animations jerky" reveals others experiencing jerky animations in Firefox.

Any idea how to get the proper person(s) attention? My client likes the idea of the way the slide show works, but doesn't like the way it displays in Firefox, so I'll have to go another route, if I can find one, that does something similar.

thanks, Mike

It is not smooth for me in Google Chrome as well, but in Firefox it is a bit more worse depending on the screen width and scroll speed.
