Browsers Which Protect Your Privacy?

valkraider asks: "Browsers are getting better at protecting user's privacy. Mozilla has pretty good cookie preferences. Many browsers like OmniWeb for Mac OS X will block images from sites based on wildcard expressions (like *ad*). Most browsers have settings to delete cookies and cache and such at the end of each session. Even IE for windows (not Mac) will allow you to 'import' a privacy file and control many things pretty tightly. Currently on PCs I use Mozilla with no disk cache, no persistent cookies, no third party images,and many blocked image sites. I can do almost the same with Chimera on Mac OS X. What are people's favorite browsers for protecting your privacy?" Which browsers provide the best balance between functionality and privacy? What privacy features would you like to see, that are missing from those currently available?"
