I received a new computer at work. I was using Firefox as my default browser. I needed to add a simulation software package to the computer. I added the software (Ansys 2021 R1 and EM Suite 2021 R1), now all Firefox tabs result in the "Gah. your tab just crashed" error. There are no logs in about:crashes. I attempted to open Firefox in Safe Mode, no change. I removed and reinstalled Firefox to the latest version, no change. I removed and reinstalled the Ansys software, then reinstalled Firefox, no change. HELP!!!!
