User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:67.0) Gecko/20100101 Firefox/67.0

Steps to reproduce:

1. We deployed version 1809 of Windows 10.

2. Export Address Filtering (EAF) is activated for Firefox (Exploit Protection)

Actual results:

Firefox randomly crashes.

Eventlog:

In our case there is a large number of affected computers and this is making daily work difficult and forces us to not be able to use Firefox.

It is necessary to have the EAF protection enabled and we can not do without it.

We would like to continue using Firefox as the main browser for the execution of our work.

Expected results:

Firefox desn't crash.

With version 1709 (Windows 10) works correctly

Can you please provide a crash report from about:crashes? This will aid in our investigation of the issue. Thanks in advance.

When Firefox crash, there are no reports from about:crashes. Thanks for your interest

we have very small changes to figure out what may cause the crashes without a report provided.

This sounds like poor interaction with Windows Defender's EAF feature.
