Uh Oh!
Similarly, whenever I am writing a report (I tend to write mine in the browser) I need to copy and paste the link for the girl I've seen. After I have pasted the link details into the report, I ALWAYS make sure to copy some innocuous text and re-paste just to make sure it is the most recent copy into the cache.
I share this machine with my SO, so a slip-up would be fatal.
I also only use Firefox to look at and write reports, and when I close FF, all private data clears. For all other browsing, I and my SO use Safari. I've buried the link to FF so that it's not easy to just click on it. I also downloaded a bunch of other browsers, under the guise that I was trying to find a browser that was compatible with a streaming video site I use...
Plausible deny-ability...
