Per a suggestion on "freenode" "ubuntu+1" chat, I removed the plymouth package and rebooted my system. The problem with firefox crashing taking me to the login screen reoccurred twice, once after typing 3 letters using IMDB search engine, and the second time after logging in again and typing 7 characters using the google search engine.
