This is great feature. Many are probably thinking “Why not implement this feature right from the beginning?” Why indeed. Microsoft was the first to come out with it’s “InPrivate” mode to protect user data. Next up was the surprise from Google, Chrome, which has the “Incognito” mode. And now Mozilla will be the last to the game (not counting Safari) to introduce a privacy mode with Firefox 3.1.
This is great news for web surfers. No longer will we have to worry about unscrupulous web sites reading cookies, history, or any other personal information stored in our cache files. As a secondary effect let’s hope that spam levels drop off and malware and spyware programs disappear … we can only hope.
