I have tried to download several different toolbars/plugins recently but firefox won't let me download them. When it attempts to download I usually get an error box that says something like "Firefox could not install the file at _____ (i.e. universe.chacha.com/toolbar) Because: Unexpected installation error Review the Error Console log for more details. -203"

I've tried to do everything suggested under FAQ's on the mozilla site but it still won't let me install any toolbars or plugins.

Not related to your question, but...

You may need to update some plug-ins. Check your plug-ins and update as necessary:

I tried resetting the settings. making sure everything was updated and getting rid of any plug-ins or toolbars that could be harmful. the only security i have on my computer is AVG so that shouldn't be keeping me from downloading. I know for the chacha toolbar to download i had to downgrade to a different version of firefox but even then it still wouldn't download.

"I tried resetting the settings.":

  • Does that mean that you deleted/renamed the extension .ini, .cache, and .rdf files in your Profile folder as specified in the article Unexpected installation error -203 when installing add-ons ?
  • Did you do the deletion/removal with Firefox closed?
  • Have you restarted Firefox after the deletion/removal?

I am not familiar with the chacha toolbar. If that is the only Add-on with which your are experiencing a problem, you may get better information on troubleshooting that toolbar by contacting the developer.

i uninstalled everything through firefox, clicked uninstall and then restarted firefox. anything that i couldn't uninstall that way i shut down firefox and then went into my control panel and uninstalled in manually. I also started firefox in safemode and checked where it said "reset toolbar" or "toolbar settings", i can't remember what it says, and then closed it and restarted firefox.
