Plugging the CSS History Leak (via) Firefox is fixing the nefarious CSS visited link colour history leak flaw, which currently affects all browsers and allows a malicious site to determine if you have visited a specific site by checking getComputedStyle against a link to that page. It’s an obtrusive but necessary fix—visited link styles will be restricted to colour and border styles (no background images and hence no more checkbox effects since the image request could leak information) and those colours will not be reported via getComputedStyle. I hope other browser vendors follow suit. # 8:01 pm

Miss Wilson, when she was a resident superintendent in this Palace, had a cat that apparently caught up to 60 mice a night. The corpses were then swept up in the morning. Finally, does the noble Lord recognise the fire hazard that mice pose, because they eat through insulating cables? It would be a tragedy for this beautiful Palace to burn down for lack of a cat.
