How do I prevent Norton Phishing Protection from clearing my cache every time I close Firefox?

My favorite feature of the most recent Firefox updates was the fact that I could, when searching for a previously-visited website, type any word from the title of the web page or any part of the URL and it would find the website immediately. Now that I have the phishing protection on, my "private data" is cleared every time I close the browser, which not only prevents Firefox from remembering previously-visited sites in other sessions but also disables the feature during my current session.

I know that I can go to Tools -> Options and uncheck "Always clear my private data when I close Firefox" and check "Ask me before clearing private data" — this TEMPORARILY enables the feature again, but because of Norton, when I reopen the browser, "Always clear my private data when I close Firefox" is checked again.

Is my only option turning off the phishing protection?

Php login security help?

When you make a login form and then process the password and user name with a php script thats called by the form. Do you have to encrypt the data somehow before the form is submitted to the php script? I notice with a packet sniffer on my web site, to try and find out what will show, my password and username is clearly shown in the http header. Can anyone get that packet or is this transmition just between me the site? If not how can I encrypt it first? Can you show me an example, or a web page somewhere on this?

i somehow put a password on my computer for security?

and now i can't get the darn thing off.
everytime we open a web page it wants the password, and now i have screwed with it so much - i have to allow cookies - in order to open a web page.

please - tell me how to get it off!

thanks soooo much!
