We just did a website upgrade. On some sites I have seen a 'Report an error' icon (in the right hind corner). After clicking on it, a user can report an error which will send along other information about their system like OS, the user's browser and what link they were on when the error occurred.
Question: Any suggestions on which module to use for it and/or how to add such 'Report an error' to the website?
Update: I am looking for something like whatismybrowser.com, which can be added like a button or tool.
