We're getting reports from customers stating that if Mozilla Firefox 76 or 76.0.1 is being installed or updated - the clients are removing that version and installing ESR 68. I've reviewed the System Logs on a couple clients and can confirm that this is happening via the detection/update process. Not sure if the code is contaminated or a version rule is incorrect. We had both regular current production Firefox and Firefox ESR as update products - I've since removed the ESR option.
