I have to use version 51 so that I can use Java to open Oracle (I refuse to use IE). I have checked the box to never check for updates, Mozilla updated anyway. I deleted everything I could find on my computer Mozilla related, re-installed version 51, checked the box to not update and checked daily to make sure that there were no pending updates. I ran it for about a week just fine, but then it crashed and when it restarted, it was on version 53. I deleted everything Mozilla again, re-installed v51, told it not to install the sneaky background service, checked the never update box, went into the about:config and made sure the setting really said not to update, then went into the prefs.js file to triple check that it really really wouldn't be set to sneak in an update, and then went and double checked that the sneaky background service wasn't installed, then made sure it didn't have any pending updates anywhere. Ran it fine for a day, it crashed, and when I restarted it, surprise, surprise I'm on v54. It shouldn't be this hard to just stay on the version I want to use. What in God's name do I have to do to keep it from updating? Does Mozilla just ignore what the user actually tells it to do and does what it wants anyway or is my version of Mozilla just trying to start the Skynet revolution? I'm pretty close to just writing a vb script to just delete everything Mozilla off my computer and re-install v51 it everyday at midnight so I can just not have to deal with it anymore, but I figured I'd ask for help here first. If I can't get help here, I'll probably just go under my desk and cry while eating glue and rocking back and forth until they either fire me or have me committed.
