Dell Latitude 9010s freeze for two minutes and then work fine, including Firefox. after unfreezing, Firefox seems to run normally. When computer freezes, disk utilization goes to 100%. All other Dells run Firefox fine. Also tried 69.0b5 and 69.0b6, no change. Tried disabling plug-ins. refresh, uninstalling and reinstalling, uninstalling again and deleting Firefox app folders.

Sorry, These are Dell Optiplex 9010 computers. Not Latitude 9010s.

Did Firefox 67 work normally on the same systems? Firefox 68 introduced a new launch(er) process to reduce unwanted DLL injection and avoid running the browser at high integrity (reduced from administrative to standard user/medium integrity).

Some security software is not happy about these changes -- Avast, AVG, Symantec Endpoint, and ZoneAlarm have been mentioned in various threads -- but I haven't been following closely which products produce which effects. But 100% disk utilization doesn't sound like a previously mentioned symptom.

We use Symantec Endpoint Protection. I uninstalled it without improvement. 67.0.4 worked without problems for us. It is interesting that it is only one type of computer that has this problem. We have 10 of them. The other Dell models and the few Surface Pros are running Firefox fine. Thanks for the reply.
