Firefox question

After the recent thread on browsers, I installed Firefox 3.5.2 with adblock plus, Google toolbar, and Smarterfox. Now, I find I can no longer right-click to save a picture or copy text. What have i done wrong?

Also check the ability to right-click on more than one site. Some websites disable right-click in an effort to prevent people copying text or pictures from the site (although it’s still possible to copy using the Edit menu).

Also, turning off javascript works often.
