Hello, I look after our Citrix VDI environment. We have an older version of Firefox (49.0.2) currently running on our shared servers so need to update this. In test I have updated to the 64-bit version of Firefox Quantum 63.0.1 I am able to load pages and about:config when logged on to the server through VMware console session but as soon as I RDP to the server I get a blank page and websites wont load. Nothing happens when I go to about:config. This is happening when I am logged on via RDP with the same account as I use when logged on to the VMware console to the same server - which is a Domain admin account. I've turned off hardware acceleration, confirmed no DNS issue as I can browse in other browsers, no Windows Firewall turned on and No AV that could be blocking this So not sure what else to check. Is there a setting in about:config that I might need to change?

Thanks in advance!

How to maintain and automatically update Firefox ESR?

We want to roll out Firefox ESR 64-bit and maintain it. We have a product called SolarWinds patch manager. That has all the updates for regular Firefox quantum and ESR but only in 32-bit.

Since our patch manager application does not maintain a repository of ESR in 64-bit, we are forced to manually keep this rolled out and updated.

How are other organizations ensuring that a deployment of ESR 64-bit stays up to date with the latest security patches, automatically? If the browser does this automatically, then we need some URL's to add to our webfilter to ensure these updates are able to be downloaded by the client browser.

I opened a ticket with SolarWinds to inquire why they are not maintaining a 64bit version of Firefox 60.x.x ESR. I'm not sure what else to use for patch management yet as I have not had time to research alternatives.

I searched high and low on the internet to find out how to lock down preferences, most that I found had incomplete information and for older versions. The last entry I found on this forum was from three years ago for version 38 and where to place the files was clear but when to use the commands lockPref, userPref and pref wasn't clear. For version 63 none of what I found was working. Well, diligence paid off. I kept experimenting until I found the correct combination. Where the different pref commands were used and the files locations was the problem. I couldn't use lockPref in the user.js file, I couldn't use the user_pref in the mozilla.cfg file. I was hoping to combine the commands together but it wouldn't work. So, here is what I came up with, spelled out clearly as to how it is setup. Almost every place I found on the internet would not have all the information spelled out leaving me scratching my head as to what they were trying to say. Here is the procedure I put together:

Mozilla Firefox version 63.00 Setup for Locking Files

1. Open Firefox and type “about:config” into the path bar.

       a.	For any preference that is locked you will see the entries in italics and the status displaying “locked”

2. Create the following as text files and change the extension on each.

       a.	mozilla.cfg – lists desired files to be locked.
               i.	The first line is always a double forward slash (//)
               ii.	Starting at the second line, use the lockPref command – examples:
                     1.	lockPref("app.update.enabled", false);
                     2.	lockPref("security.tls.version.min", 2);
      b.	local-settings.js – uses mozilla.cfg to lock the preferences. 
              i.	Add the following entries. Do NOT place a “//” on the first line of the file.
                     1.	pref("general.config.filename", "mozilla.cfg");
                     2.	pref("general.config.obscure_value", 0);
      c.	user.js – changes the settings for each of the listed preferences.
              i.	Enter the same entries that were in mozilla.cfg but use the “user_pref” command at the beginning of 
                       each entry. Do NOT place a “//” on the first line of the file.
                    1.	user_pref("app.update.enabled", false);
                    2.	user_pref("security.tls.version.min", 2);

3. The folders where mozilla.cfg and local-settings.js files are located have full Administrators and System rights assigned, however to make changes to these files copy them to another folder (i.e. Desktop) then copy it back into its respective folder. The UAC prompt asks to accept the changes. A regular user shouldn’t have rights to do this.

4. Location is very important for each of the above files. Place each in their respective directories as shown below.

       a.	mozilla.cfg is placed into:
               i.	C:\Program Files\Mozilla Firefox
       b.	Local-settings.js is placed into:
               i.	C:\Program Files\Mozilla Firefox\defaults\pref
       c.	User.js is placed into:
               i.	C:\Users\”username”\AppData\Roaming\Mozilla\Firefox\Profiles\*this folder name will vary for each installation*

5. To disable the files listed in mozilla.cfg, open the local-setting.js file and add “//” to the beginning of each line to remark them out, save and then restart Firefox. Verify in Firefox under “about:config” that the “locked” status was removed. Of course, to lock them again, remove the “//”.


My question now stands as when GPO is set up to push, is it these three files pushed to their respective locations for each roaming profile and computer?
