Firefox 67 will not start, but Firefox 66.0.3 worked just fine. The Event Log shows the following when trying to start Firefox 67:

hi micbow, unfortunately it appears that your security software (apparently "Lumension Endpoint Security") is meddling or trying to inject itself into firefox and cuasing the startup crash this way. could you please try to reach out to their support as well and inquire if that's a known issue and if there's any update or workaround available to fix this. thank you!

Tech Support for Lumension EndPoint Security says that is used just as a patch management for Vipre. I disabled the service no luck with Firefox 67. Funny thing is on my laptop Firefox 67 is working with no problems and it is running the same service as my workstation. I tried installing the beta of 68 and I also tried installing one of the nightly builds to no avail. I now have 4 people that the issue is happening to.
