I keep re-installing Firefox, in order to keep an older version that I prefer. I intentionally install an older version of Firefox, but then Firefox keeps automatically "upgrading" or installing the newest version, without my permission, without asking me, without me doing anything, or even seeing it happening.
But I don't want the newest version of Firefox. I don't like it. I want a specific older version, and I have the installation file for that version. Is there any way, or any setting, that will stop Firefox from automatically bumping me up to the newest version ?
