Steps Completed -Reboot machine -Update MacOS -Update Firefox -Clean reinstall Firefox -Attempt boot in safe mode (immediate crash or no option) -Update all drivers

I have not been able to boot Firefox for several weeks now, I've tried my best to fix it but have yet to succeed. I do have several add-ons, but can't modify or delete/disable because Firefox crashes on startup. Any help/ideas would be greatly appreciated. My crash reports cite EXC_BAD_ACCESS / EXC_I386_GPFLT . I haven't been able to find an explanation of those errors.

hi, this is a known issue in catalina beta 5 - please update to beta 6 which should contain apple's fix for this problem.
