Problem with that & cookies is it's impossible on other sites where you want preference cookies, but not the others.
Because of that, I downloaded Cookie Pal. I am a minimalist - don't like toys & playing with shareware, but this program has been a Godsend. It's small, zero bugs, and allows you to see every individual cookie offered and select "accept," "reject," "always accept", "always reject" and "reject all from this domain". After a few days surfing, you will have created your own custom filters.
I couldn't do without it.
(BTW, I have no interest in the co, lol. Just a happy user. =] )
That sounds very much like the functionality that is built into the Mozilla browser that I use. It is has been a useful feature at times. Unfortunately, I've found that I want some sites to be cookie-enabled at times and cookie-disabled at other times. Since my list of cookie-disabled sites has become very, very long, it became too much trouble to scroll the long list and re-enable cookies for a particular site. It's easier to simply leave cookies disabled all the time and turn them back on as needed.
I have the source code for Mozilla, and I've been wanting to add a toggle button for cookies to the browser's toolbar. I have yet to find a day with enough free hours to implement such a luxury though. I believe it would be the least aggravating method yet for dealing with cookies, and I'm somewhat amazed that browsers don't come with such a convenient button.
