Same problem, I can't scroll webpage. Thanks for all the help. We've tried to crowd-source the reproduction effort and haven't had much luck so far, so you're one of our only connections to this bug so far. Could I please ask you to try 2 more pref changes to see if it changes anything? For both of these, make sure that "security.sandbox.gpu.level" is set to "1" (which should break scrolling), and then make the following changes separately: 1) Set "gfx.webrender.force-disabled" to "true", restart Firefox, and observe if scrolling is fixed. Set the pref back to "false" when done. 2) Set "layers.acceleration.disabled" to "true", restart Firefox, and observe if scrolling is fixed. Set the pref back to "false" when done. Thanks!
