I cannot update any of my Add-ons. When I try, I get the following message (this is the one for Adobe Shockwave, though the same error appears for all the add-ins): "Firefox could not install the file at http://platformdl.adobe.com/NOS/getPlusPlus/1.6/gp.xpi because: Unexpected installation error Review the Error Console log for more details. -203". I first noticed this when trying to download Google toolbar fro Google, but now I see the error message pops up whe I try to update any of my Add-ons. When I try to go the Error Console for any of the add-ons via the Options button, the Add-on module freezes up and I am forced to shutdown and reopen FF.
