Rated 4 out of 5 stars

This tool is damn nifty, especially for airheads such as myself, thanks for updating it!
Only problem is that, for a visited link, both the address and the time of the visit appear on an invisible background making it very hard to read them, instead of the white background on which link addresses usually appear when you hover over a link

You're right, I'll see how to make an opaque background so the text can be read clearly.
