Personal tools I've made for use with the Opera browser, the original (12.x). Not the new Opera based on Chromium.
Opera has a bug where it will eventually overflow the visited links file (vlink4.dat) with too much data, generally triggered by anchors in URLs, commonly used by sites like G-Mail. This tool attempts to rebuild vlink4.dat in a way that keeps as much information possible and removing corruption.
Output the usernames and passwords (and their associated URL) from wand.dat.
