2) Follow those instructions from https://www.mozilla.org/projects/devpreview/releasenotes/ :

Uninstalling the Mozilla Developer Preview


From the Start menu, choose Control Panel. When the Control Panel appears, double click Add/Remove Programs. Find "Mozilla Developer Preview (3.7a5)" in the list and click Remove to uninstall.

Does that work for you?

Unfortunately, no. Neither does Revo Uninstaller nor "C: Programs Files/Mozilla Developer Preview/Uninstall/helper.exe".
