Firefox 4.0.1 is not secure. http://www.mozilla.org/security/known-vulnerabilities/firefox.html#firefox5

To change your automatic update settings, check here:

orange Firefox button or Tools menu > Options > Advanced > Update "mini-tab"

I've got the updates mini-tab set already so Firefox asks me what I want to do, and it does not do it automatically. I will not change this setting. All I want to know, please, is how to tell Firefox to stop telling me an update is available once I've decided I don't want to download it and install it.

No, as far as I know, you cannot "hide" an unwanted update. Therefore, you may have to just turn off Automatic Updates on the tab noted above (uncheck Firefox).

If you prefer to experiment, check out the setting described in the following article:

http://kb.mozillazine.org/App.update.promptWaitTime

Maybe if you enter a really huge number of milliseconds you can extend the time between reminders to a week? However, since this affects security patches, you might want to reset it after you finally upgrade to Firefox 5 (or 6, or 7...).
