I just upgraded to the latest Firefox but every time I start it I get an error message which will not attach to this message. Some of it says [Exception... "Could not convert JavaScript argument arg 0 [ns]Supports.QueryInterface]" nsresult: 0x80570009 (NS_ERROR_XPC_BAD_CONVERT_JS)" etc....... When I click OK Firefox loads the latest version but this happens every time I open the program Please help me to remove this or I'm going to simply revert to Chrome as this is so annoying! Thanks, Chris

Thank you very much. I did as you suggested but still got the error. I uninstalled Firefox completely then reinstalled it and the problem has solved itself. Thank you for your kind help!
