Thanks to Dear Miss Mermaid, I can tell you about something good. It's Do Not Track Plus, and it's free.
After installing, surfing is fast again. I'm not waiting for data suckers to download now. Please wait while we extract your shoe size ... one moment as we jot down your underwear preference ... pardon the delay while we notice you shop for discount embolism stockings ... sorry for the pause as we snicker at your recent purchase of "Fifty Shades of Grey - bluing at home like Granny did it."
Even if you don't have any ads or widgets on your blog, you still have tracking going on. Hope you don't mind that I'm blocking that now. And, when you go to your trusted sites - CNN, NYT, TMZ, The Good Luck Duck - you are getting slammed with tracking cookies. And, you wonder why you can't lose weight.
Google Friend Connect tracks you, too. You might decide you don't mind that so much, and so DNT+ lets you say "okay" to individual tracking sites.
If you end up not wanting it, you can delete it from your extensions, add-ons, plug-ins, or whatever your favorite browser calls them. But, I think you'll want it.
Do Not Track Plus.
