I use IE and Firefox. IE has better privacy control. Haven't used opera in several years, so I can't tell about it.
By the way, here's a little know tip:
I'm just tired of instructions being posted for Prompt commands.
Adaware and Spybot usually come up clean if IE6 controls are set correctly. I usually find 1 or no items every week.
How can a "cookie manager" beat IE6's controls? If you use iespyad, spysites, and SpywareBlaster, they load almost 7K of restricted cookies into the block list.
I have 1st. and 3rd. party cookies blocked 24/7, always allow session cookies checked,( session cookie has to be checked to work with edit features), and under edit button,( "sites" with SP2) I only have 7 ( I think) sites on the allow list which will act like a firewall "pass list". If I don't delete cookies for a year, and look in cookie folder, I never find more than the 7, and that's only if I visit all 7 sites during the year.
Set Tools, Internet Options, Privacy, Advanced, Block 1st. and 3rd. Party cookies; Check "Always allow session cookies", hit OK. THEN Click EDIT,or SITES in SP2, Type in or paste paypal.com for instance, Click allow. Check OK as you close each menu. After a year of surfing, that's the only cookie to be found in that folder.
YOU WILL KNOW WHEN A SITE YOU NEED WON'T WORK AND CAN ADD THAT SITE AT THAT TIME IF IT'S NECESSARY.
One Caveat; Excite sets a tracking cookie, and after every update of SpyWareBlaster, I have to locate it at bottom of list, pick "select All" and uncheck excite, pick Remove Protection.
A sidebar: Get Camtech2000's free version of Spysites. It not only loads restricted sites into internet zone and block list of IE cookie stopper, but it tells you what each site puts on your computer. Read their " worst offender" list. Some "cookies" have java script viruses. Get updates through it's help menu. :Thumbs:
