I use Opera for my everyday browsing. I usually have Firefox open for mail at the same time, but it's locked down with "NoScript", and it's always a guessing game as to which scripts I need to give permission for a website to work correctly.
Obviously though, I'm being tracked on Opera to some extent. But its ad blocker does work very well, sites keep telling me to turn it off.
It keeps my old mind nimble though, when I get targeted ads, to remember where I visited before, as opposed to where I am now, (in the cyber world), when I got the ad.
Well, I (if I do say so myself), have an extremely high threshold of sales resistance. So, virtually 100% of all the horse poop people are trying to sell me, stays in their warehouse.
One fatal mistake a web surfer can make however, is to linger on a site you have no interest whatsoever in their product. You'll be counting ceramic figurines or similar, jumping over the moon as you try and go to sleep.
Unfortunately, the only sales pitches I can't resist, are my own. This can lead to high credit card balances.
That said, I keep my skills honed by answering the front door when I know full well it's Jehovah's Witnesses. This is like the Jujitsu of sales resistance, since you need to use your opponents own strength against them. I take the pamphlets, thank them, tell them to have a blessed day, shut the door, and then go back to worshiping Satan in my basement.
