Autoclick software

[Hardi]

Do you know, where can I get an autoclick software for linux?
You know, like a program that closes annoying windows like the message box in Mozilla Firefox: "The Document contains no data"

Dunno about auto click but you can stop Firefox from popping up message boxes by doing this:
1. Type "about:config" in the address field.
2. Type "error" in the filter field on the about:config page.
3. Double click on the line called "browser.xul.error_pages.enabled" to change it's value to "true".
4. Restart Firefox.
