You can try to disable hardware acceleration in Firefox.

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.

None of that helped. I hope that Mozilla can get the issue fixed. I'll be using Google Chrome until they do.

inproc_agent.dll = Kaspersky Inproc Agent

igd10umd32.dll = Intel(R) Graphics Technology

msmpeg2vdec.dll = Microsoft DTV-DVD Video Decoder

All windows updates are up to date. It doesn't crash when starting, but during facebook use. I can tell when it's going to crash, because things start slowing down.

How much of Kaspersky should I disable? I tried the one for web anti-virus. It caused Facebook to run MORE slowly and crash earlier. I am so frustrated.

As a test, disable all of it. Once it is known to be the problem, you can contact their support site.
