JavaScript should be the only scripting type you need to worry about. I would check your error console to see if any errors are being thrown.

But yes, if you are having similar issues on other sites, it's quite possible one of your extensions is blocking the JavaScript. That or you have a very touchy firewall. I would disable a few of your extensions and find out, knowing of course you can just re-enable them if they are not the culprit.
