What support for the tool bar in Norton 360 version 5.2.2.3 for Firefox 17? Will the Norton Toolbar be adjusted to to work in Firefox 17 if we still have this not-so-old version of Norton 360? I WANT to upgrade to Firefox 17 but do NOT want to upgrade N360 yet to version 20; instead may go as high as version 19, not yet, and not to version 20.
