I keep a tight computer,
I'v used Firefox for awhile now, 8 years at least
Cookies are Off unless I need them for something
Zero online cache allowed
Current Adblock Plus
I'm particularly anal about Local Shared Objects and not allowing anything stored,,, especially 3rd party.
I use CCleaner everyday
****So here's the deal;
I was just looking at a cassette for my bike on Amazon yesterday, and today I get an email from Amazon about the exact cassette I was looking at.
(no, I didn't add to cart & no, I was NOT logged in)
To put this as mildly as possibly, I was not impressed!!!
