How do I permanently remove Mozilla Maintenance Service?
Every time I manually update firefox, it reinstalls the automatic update malware "Mozilla Maintenance Service". I can't stop this malware from being installed with my browser every time I update Firefox. I call it malware because its not wanted, and it behaves like malware by secretly downloading content without my consent and then shutting down my browser when it finishes by blocking access to all new tabs.
I've tried adding policies to stop auto updates, but Mozilla Maintenance Service ignores all policies. I'm going to see if I can contact AVG and explain to them that Mozilla Maintenance Service is malware and see if I can get it classified as such to see if that'll finally get through to someone because I'm sick of this crap constantly being installed and forcing things on me whenever they want and not when I want.
Now after this update, every google search forces open my location service trying to force me to give location rights. This update is even more malware than all the other updates before hand. Firefox is getting extremely dangerous.

I've disabled the service in services, and quarantined the file in my antivirus, and contacted AVG about it as well. Since the file behaves like malware due to it being installed every time I update even when I don't want it, it is kind of malware. It downloads without consent, and crashes another program after it does. Its almost the exact definition of malware.

See:
1) The article for Maintenance Service is wrong, there is no option to disable background service. The option does not exist. I checked Thunderbird too, no option there either. 2) Every time I've uninstalled this service, it reinstalls its self.

Again, I said that Mozilla Maintenance Service ignores policies. When an update is applied, policies are deleted. Mozilla has decided that the Distribution folder is obsolete and every update removes it. You have to use GPO edit instead. How do you not know this being a long term user here? I find that rather strange.
I did download the GP templates now though. https://github.com/mozilla/policy-templates/releases I'll try this and see if it works any better. Meanwhile, I will keep Mozilla Maintenance Service in my antivirus quarantine to ensure it doesn't come back, hopefully.

Please stop telling people to use templates like that. Mozilla does not support them anymore. It uses a GPO Policy editor.
However today it looks like Mozilla bypassed my shit again. Honestly. Mozilla is raping my computer with unwanted forced updates. I even classified maintenance service as a virus in an attempt to stop it, and it didn't stop it.

Mozilla Service came back again, I tried re-classifying it as a virus and then uninstalled it. No idea how to prevent it from returning.
My GPO settings are all still in tact, Firefox uses the GPO settings as shown in about:policies, showing that the policies from the GPEdit.msc are active.
Mozilla Maintenance Service overrides all Policies.

Agent Virtuel,
One... Stop telling people to use policy json files.
THEY DO NOT WORK ANYMORE. MOZILLA MOVED TO GPO!
I have REPEATEDLY TOLD YOU that I have tried this, and the policy files get deleted every single fucking update.
Two... The GPO does not work either. Mozilla Maintenance Service installs its self quietly like a priest alone in a room with a little boy. Then Maintenance Service overrules all policies. See attachment for proof.
Three... I did add a registry value to the right spot, but two others were already in there, created by the GPO policy apparently both had already tried to disable updating but failed.
Four... Mozilla, how do I disable your maintenance service? It shouldn't be installed. I've uninstalled many times now. Get this malware off my machine.
Hello
As for me.

I suspect Agent Virtuel is an AI or bot running on the site. This user does not actually read content, ignores things, and just forwards around links.

There is no bots being used to do support on this site as the bot we do have SumoBot is being used for behind the scene stuff like flagging potential spam threads/replies for moderators to review. It is also being used to help translate/keep update KB articles in the less active locales after en-US article is updated.
