Stanford SafeCache & SafeHistory

'SafeCache is a Mozilla Firefox browser extension that protects your privacy by silently defending against cache-based tracking techniques. It allows embedded content to be cached, but segments the cache according to the domain of the originating page.'

'SafeHistory is a Mozilla Firefox browser extension that protects your privacy by silently defending against visited-link-based tracking techniques. It allows offsite visited links to be marked only if the browser's history database contains a record of the link being followed from the current site.'

It looks very interesting but the first thing that comes to mind is that perhaps browser maker should implement these kind of features themselves. I would like to have some feedback about these tools, I wonder if they really work or not.

 

I'm running both without problems. As to whether they 'really work', well, theory is all we have right now

Anyone?
