NO, I don’t need web pages to have the ability to play with visited status — I can simply think about on-line stores seeing what I’m buying from their competition and utilizing that as advertisement tracking.

A different colour for visited links is enough, and if a page queries the colour it may be informed the unvisited colour, or if the info sort allows, it can be informed both colours.

Last time I checked, Places lookups weren’t the quickest thing on earth. The inventory resolution — to provide a desire that can be enabled to guard your self, presumably even referencing that preference in the person interface — is not sufficient in this case. For typical pages, “noticeably slower pageload” expensive, if I recall the numbers proper for what quantity of history lookups occur. I’ve made a proof of concept of this and it really works fairly nicely. Now that Firefox 3 stores ninety days of history, it can dig up a great number of pages I’ve visited.

I was talking to Sai about this and he suggested I make a remark here — so I have not read by way of and understood the present state of discussion, apologies. Those are each detectable via performance characteristics. Allowing them to be set wouldn’t fix the exploit in any helpful way.

I assume the pref added by the patch is beneficial for a small fraction of users, and perhaps for a larger variety of users if safety specialists inside or exterior Mozilla clarify the problem. Here’s a patch for a structure.css.visited_links_enabled pref, defaulting to true. In other words, trade some design prospects for privateness, while keeping the complete performance of displaying visited links. For each visited URL, make a background request to a server that can fetch a copy of the URL and return a listing of hyperlinks on that web page. 1) It would still be potential for an attacker to assemble a convincing phishing web page that appears like Wells Fargo to a Wells Fargo buyer and Citibank to a Citibank customer.
