On my company device, Edge and Firefox ESR are installed by default and should be used as main browsers. Since I'm developing web applications, I use Firefox and Firefox Dev Edition regularly, which I installed by myself.

However both versions of Firefox are crashing from time to time (after 5 minutes or 2 hours for instance) for some weeks now. New profiles, complete reinstalls and safe mode didn't help to solve the issue.

Today the Windows event log came to my mind and I took a look at it. The crashes are logged and it blames the crash to the module PayloadRestrictions.dll.

How can I solve this issue? Keep in your mind that I have access to admin privileges, but GPOs still restrict some actions and I can/should not modify system files on my own. I don't want to increase the risk of system or security issues for my company.

The module PayloadRestrictions.dll is a Windows security feature, injected by Windows into all non-exempt processes. The feature that is causing your crashes is probably Export Address Filtering (EAF), defined as:

Detects dangerous operations being resolved by malicious code. Can optionally validate access by modules commonly used by exploits. App-level only

Here is how to disable it for Firefox:

  • In Start menu, launch Windows Security
  • Go to App & browser control
  • Scroll down to the Exploit protection section and click on Exploit protection settings
  • Switch from System settings to Program settings
  • Find firefox.exe in the list, click the entry to expand, then click Edit
  • Scroll down to Export address filtering (EAF)
  • Switch it to "Audit only" to stop the crashes. Turning it off entirely would probably also help.

You will need to repeat this process after every Firefox update.

  • Upvote for this precise and promising answer. Sadly these options are locked and cannot be changed by normal user accounts. Do you know the reasons that could make the dll crash? The security feature per se should not constantly crash the browser, right?

  • Your post specified that you had access to limited admin privileges. Perhaps, if you can, excluding the Firefox installation from Windows Defender might also do the trick.

  • Yes, excuse me. With normal user I meant users of the common clients, even if they got admin rights. I think these settings only can be changed by the 'super admin' who stage the devices or something like that. I'll try that. It can also be, that I actually cannot do anything about the issue due to missing privileges.

  • The Windows Defender settings are locked too...

    All that is left for me to recommend is fully patching Windows, besides begging the domain admin to give you the required permission (or to do it himself).
