Basically a shutdownhang means something within Firefox is not responding or running slow.

Is this with all websites/pages, some, a few?

What were you doing at the time? surfing, watching a clip, reading something . . . .

I noticed the crashes occurred within two minutes of starting the browser.

Start Firefox using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

Use these links to create a new profile. Use this new profile as is. Is the problem still there?

Hiya, and sorry for the slow reply .

This crash is consistent across any computers with firefox installed on our corporate domain. It occurs while not even using firefox as it tries to update itself in the backgroud.

A few months ago I was tasked with making sure our browsers stayed up to date via GPO. I did a similar procedure for Google Chrome and Microoft Edge and they have been updating themselves (In the background) fine.

I am just wondering is this an admin rights issue ? All users are NOT local admin , just standard users. When the firefox browser is trying to update is it struggling to do so because the user is not a local admin ?

Chrome and Edge had similar issues, until their devleopment teams allowed update as non admin.

Procedure I used is below, and based on below articles, is there a better way to do this ?

https://www.ghacks.net/2014/06/09/change-firefoxs-automatic-update-behavior/

1. Download and unzip the admx.zip 2. Open the Admx folder. 3. Copy firefox.admx and mozilla.admx and put them in your Policy Definitions folder. (Example: C:\Windows\PolicyDefinitions) 4. In the /en-US folder, copy the firefox.adml and mozilla.adml files and put them in the en-US folder in Policy Definitions. (Example: C:\Windows\PolicyDefinitions\en-US) 5. Open Group Policy and go to Computer Configuration Policies Administrative Template

I had to make 3 changes in GPO , see attached. Application Auto update Background updater Don’t check if default browser

I called for more help.
