It's worse now --- My 2003 Saab 9-3 (good riddance!) mirror glass fell off and had a black rubber-ish/glue-ish/foam-ish stuff holding it on got tired and decided to take a nap. FWIW, the glass didn't smash and I was able to pick it back up. I scraped off the old stuff and used some epoxy to put it back in.
