The new version of the Firefox web browser (ESR 60) has been pushed out to all CAT supported Windows computers. In addition to losing support for Java enabled websites, the new Firefox may break old Personal Shortcuts you may have set up that use Firefox to bring up your favorite websites.

This can be fixed by deleting (or un-pinning) the non-functioning shortcuts and recreating them from the new shortcut in the Start Menu. (Note that the new Shortcut Icon and Application will look slightly different from what was there previously.)
