I have add-ons for no-script, screengrab, and forecastbar. Until yesterday, they all displayed icons (or actual weather info) on a line just above the bottom Microsoft line and at the very bottom of the browser. Now they've disappeared. Noscript shows as "options" first time I get to a page, but never displays status (names of scripts allowed, etc.) and won't display once I've set. Screen grab icon and weather info have completely disappeared. I've tried reinstalling, but it makes no difference. The only thing I've done in the last day is install the latest version of Adobe Flash. How do I get this back
