"Firefox could not install the file at https://addons.mozilla.org/firefox/downloads/latest/3036/addon-3036-latest.xpi?src=browse because: Unexpected installation error Review the Error Console log for more details. -203" Ii noticed that a have a few updates and I am getting the same type of error message for them.
