web browsers constantly crash in 16.04

Most recently the default web browser (Firefox) crashes. --safe-mode does not help. Removed, etc. reinstalled, still crashes. Installed chrome - crashes. Completely reinstalled (reformat, etc) 16.04.2 Feb 2017 CD - still crashes. On a side note, even though I checked update while install box after first boot there were 11 updates. Firefox still crashes after 11 updates on a virgin install. This is an older i386 machine with Nvidia graphics card. Everythinhg else works fine. Obviously, I write this on a different machine, 64bit laptop, 16.04.
