I don't know how the update does things since I have always done a clean 
install.  But, when you updated, do you still have the old add-ons in 
/home/"username"/.mozilla/firefox/?  There will be another tier to the 
tree under firefox with a string of letters and numbers ending in 
".default".  If your old add-ons are in still in there, but not 
compatible with the new version of firefox, maybe that is the problem?  
If so, you could delete them and see if it helps.
