ajax.googleapis.com stopping my Firefox

"If you don't need it, black hole it in the hosts file by adding

0.0.0.0 ajax.googleapis.com

You might as well take a look at a tutorial and a block list to keep you safe.

It's a good idea to block the connections to your computer from those domains rather than try to block the script of an already established connection."

I've randomly ran into this before with Firefox. If you get Firebug, you can go to the Net tab, right click the script that is still loading, and select "Stop loading". This will get around the issue.

"Could you enter the ""culprit link"" (that every 2nd web 2.0 site uses) in your Fx address bar and load it manually?

Try some other sites that references this JQuery library. Just Google the URL, you'll find enough examples.

Have you tried it with a new, clean profile? Addons sometimes work against eachother (NoScript vs. ABP problem...)"
