When all the 3rd party content is linked properly (i.e. <script> blocks at the bottom of page) - nothing bad happens, you would just see blanks instead of third-party content.

When it's not linked properly (as far as I know most of those 3rd party services by default advertise the "wrong" way) - not only it would display a blank or half-blank page when the 3rd party service is down, also all the page loads are noticeably slower for everyone on every page load.

I.e. I use neither facebook nor twitter nor google+, but half of the internet is loaded a few hundred milliseconds slower because every page is crammed with their fairly useless buttons.

Why useless? First, that functionality should be part of the browser, not of the webpage. I should have a share button in my browser, for every page I see, and also it would prevent those services from tracking me.

Is there an firefox/chrome extension that:

- Provides Like, Tweet, +1, Digg and all the buttons in the toolbar (only ones I need)

- Prevents browser from accessing button embeds therefore disabling tracking?

I would install it in a heartbeat.

This is why I prefer a bookmarklet, for the specific (of the 100s possible) social sharing site I happen to like to use.
