I get "error: TypeError: boxOverlay_AVG is null." What is going on?

Whenever I connect to the internet (Google) a pop [JavaScript Application] box indicating "error: TypeError: boxOverlay_AVG is null.

Don't know what's going on?

I note that I cannot print some pages of websites.

Since the message AVG references, you can try disabling your extension of AVG toolbar and see if this eliminates the message. You can do so here:

Firefox orange (or the Tools menu) button > addons > Extensions category

If the message disappears after you restart Firefox, it may indicate that your AVG software needs an update.

If the message persists, we'd hunt down another cause.

Moreover, Firefox 21 is now available. Not sure, it will make a difference for other issues, but you can update using the:

Help > about Firefox > button "Check for Updates".

Could you describe the printing problem in more detail? If you remember pages that have problems, it might be useful to get these URL, assuming that an account is not necessary to view them.
