How do I stop Firefox from upgrading automatically?

I have tried all options under tools options advanced update and NONE of them disable automatic updates. Whichever one is selected, at some point Firefox will upgrade without getting user approval, which is complete and utter crap.

I have to maintain an application which must run on Firefox version 3.6, cannot be ported to any later version, and is only used to access the control application.

I'm sick and tired of having to uninstall and reinstall Firefox every time it goes in direct violation of my settings and updates itself automatically. Why even have a setting for this if hte setting is completely ineffectual?

Chosen solution

You can install an older portable Firefox version to access websites that do not work with the current Firefox release.


You can set the app.update.url prefs to an empty string on the about:config page to prevent Firefox from checking for updates.
