My Firefox is Sluggish and Crashes Fix

Are you about ready to throw your Firefox browser in the garbage and go back to MSIE?  It’s slow, it uses up all your memory and then – to add insult to injury – the #$%@#$ plug-in container crashes.

There’s two things that are responsible for your woes.

1. Flashplayer.  nearly every webpage nowadays  has some ad on the page which uses flashplayer.
2. plug-in container.  It came along in the early (think single digit) version of FF and really isn’t needed in the newer versions (24+)

This is a 2 part fix and will work on machines running Win7 and Win8.1, i can’t speak about any other OS. You have nothing to loose if you run other versions of Windows and have googled for a fix, tried all the other ones you found and none worked. I certainly have spent hours looking for help and have tried most every suggestion I have come across.  This solution below is the ‘magic combination’ that  works for the computers I have encountered with this problem.
The images shown were taken from my Win7 system.  For Win8.1 use the search to find system properties.
