Firefox https not working after upgrade ASA to 9.14.2.4

[jslegers]

Hello,

Last week we have updated our ASA 5516-X firewalls with ASA Software version 9.14.2.4. After this upgrade Firefox 85.0 has some issues with HTTPS page.

It gives an PR_CONNECT_RESET_ERROR.

If we use Edge or Chrome then there is no issue.

If I go directly to internet without the firewall the pages load normally. 

Has anyone else seen this behavior?

Hi,

What feature you have on ASA which inspects HTTPS.? Try to enable term
monitor on ASA when testing from FF to see why the connection is terminated.
