I deleted these files that firefox installs automatically via the extension popup dialog. ~/.mozilla/plugins flashplayer.xpt libflashplayer.so
Then I installed via, sudo apt-get install flashplugin-nonfree
and the frequent crashing has not happened in firefox and epiphany while playing flash videos
