nVidia Geforce 7600 W10P. Starting with the version of firefox 67, and, at least, until the last after launching firefox begins to flash: you press the PCM - let go-something flashes, then again disappears and hangs. You can't use it. In 66.0.5 and earlier, this was not the case. I've seen similar crap on my computer in the latest versions of Google Earth plus and iFunBox. It seems that either this OpenGL or this Webrender is to blame, which they introduced from version 67. Starting with the 67th version, there and about: config shoveled and so on - how to start again, infections, your cool-Vert and again everything flies. Hardware acceleration enabled-disabled-sense-0.
