Just for fun, testing and learning blocking FF updates trought EIS

Hi @camelia, BackgroundAppUpdate"=dword:00000000 means not enabled because its value is zero (i.e. false).
My above registry changes may include some privacy (hardening) settings that are maybe too strict for your taste, well just go ahead and check it out.
You can always remove what you don't like and be careful when doing surgery in the registry.

It's an integer value. 0 for OFF and 1 for ON.

Boolean would be YES or NO, TRUE or FALSE and a sting is a data value. Like some text for something.

And JSON is a human readable code. JSON stands for JavaScript Object Notation. You can read a JSON file in any text editor. I use Notepad++.

Firefox continue checking for updates every 7 hours or first start computer windows!

How do I know? Because SBIE Plus v1.12.5 is not empty every 7 hours or when first start computer.

I would like to add to my registry something like:
"FF Don't Check Background Updates every 7 hours OR When first start"

Code:

Windows Registry Editor Version 5.00

; Disable/Enable Firefox Updates (from v63 and upwards): 1 = Disabled / 0 = Enabled

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox]
"FF Don't Check Background Updates every 7 hours OR When first start"=dword:00000001

My actual Disable FF Reg File looks like

Code:

Windows Registry Editor Version 5.00

; Disable/Enable Firefox Updates (from v63 and upwards): 1 = Disabled / 0 = Enabled

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox]
"DisableAppUpdate"=dword:00000001
;--------------------------------------------------

Maybe a Key from this Reg File can do the job, but I do not have any idea which one could be, and I don't need all the Keys enabled or disabled of the following REG file at this moment until I fully understand them.

Code:

Windows Registry Editor Version 5.00

Hi, does your Firefox at least recognize the administrative rules / policies?
It should show them if you enter about:policies in the URL bar.

The following registry entry should be good enough to stop it from looking for updates.

Code:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox]
"DisableAppUpdate"=dword:00000001
"BackgroundAppUpdate"=dword:00000000
"DisableTelemetry"=dword:00000001

Did you check for (maybe orphaned) Mozilla Firefox update tasks in Windows task scheduler?
I have only Mozilla\Firefox Default Browser Agent and I disabled it.

If Firefox in combination with Sandboxie does not follow the registry imposed rules, then maybe try policies.json.
