I believe this colouring of links is based on checking the link target 
against a list in RAM in the current running instance of the browser.  It's 
not written to disk anywhere, so when the browser is shut down or the 
computer rebooted, it's gone.  The next time the browser runs, it starts 
building a new list from scratch.
