I tgried to install 1 click weather add-on, but it did not install. Now when I ope FF4 the following message pops up: [Exception... "Component returned failure code: 0x80520012 (NS_ERROR_FILE_NOT_FOUND) [nsIFileInputStream.init]" nsresult: "0x80520012 (NS_ERROR_FILE_NOT_FOUND)" location: "JS frame :: chrome://1clickweather/content/js/utils/filemanager.js :: <TOP_LEVEL> :: line 233" data: no]

Then anogther similar pop up shows: [Exception... "Component returned failure code: 0x80520012 (NS_ERROR_FILE_NOT_FOUND) [nsIFileInputStream.init]" nsresult: "0x80520012 (NS_ERROR_FILE_NOT_FOUND)" location: "JS frame :: chrome://1clickweather/content/js/utils/filemanager.js :: <TOP_LEVEL> :: line 133" data: no] Once I hit OK for these messages, everything works fine.I dont care about the add on but I want to not have the error messages.

Uninstall 1-Click weather add-on. Then restart Firefox. It worked for me.
