First, Type about:preferences#advanced<enter> in the address bar. Under Advanced, Select Update.

[v56+] Type about:preferences#general<enter> in the address bar. Select Update.

Select Never Check For Updates.

Also turn off Use a background service to install updates <Windows Only>

I have done all of that some weeks/months ago. It does not work. Unfortunately the unwanted update just keeps coming back. I think you are saying Chrome is the answer.

I called for more help.

What are you using as your home page?

My home page is set to Google (Australia). I see that many other people have this updating issue and it does not appear to have a solution. I appreciate that you are trying to be helpful though.

You are certainly pushing me into Chrome, which I don't like much.

FYI Chrome does update behind the scene but it will not tell you that upfront. There is a way but that isn't advised on here.

1. Yes I know that but at least it doesn't stop dead when you scroll. 2. "There is a way" to do what?

Some Windows users have gone as far as deleting this folder in the computers Programs Folder; Mozilla Maintenance Service

Thanks - I'll give it a try.

What security software do you have?

We have seen issues reported with AVG/Avast security software.

I use Eset and i'm fairly sure that's not the problem. FredMcD's suggestion is working so far.

Note that you can uninstall Mozilla Maintenance Service via the Windows Control Panel, so no need to remove this folder manually since that leaves traces in the Windows Registry.

Thanks - I will do that too

Unfortunately getting rid of this Maintenance Programme does not stop the latest Firefox downloading.

I find it quite obnoxious of any company to insist you do what they want rather than what you want, especially when what they want is for me to use what is, in my hands, an inferior product. 5 seconds per scroll movement is quite unacceptable.
