Can you give a little more context for your question?

This is for Firefox 22 on Windows? or Mac?

Did Firefox work normally up to now and this just started suddenly? After an update? Out of the blue?

When does the message appear -- at startup? Using particular features?

Does it block Firefox from running completely? Disable an add-on?

Thanks.

Make sure that you meet the System Requirements (GTK+ and GLib) for the current Firefox version.
