Hello people. I hope that someone will be able to help me. When I start Firefox I receive following error:” The NTVDM CPU has encountered an illegal instruction.” I really have no clue why is this happening. I mean, everything worked fine for a long time. I would really appreciate any help you can provide me.
Hello. You will have to perform some troubleshooting. First check that you are not running Firefox in compatibility mode. Second, start Firefox in safe mode. No extensions will be loaded in safe mode and you will be able to find out if extensions are causing problems. Post back when you perform these checks so we can continue to analyze problem.
