Not A problem I have come across personally but I did notice this http://kb.mozillazine.org/Unable_to_install_themes_or_extensions#Unexpected_installation_error_-203

It would appear possible causes may include problems or blocking relating to security software, or corrupt files Hope it helps.

i had this issue also... but once i looked into it calmly and logically it turned out i was trying to install an add on for a future version of firefox.

my example is i was trying to install fireftp for firefox 4 but i only had firefox version 3.0...

could be a similar issue for others...?
