I don't know if Firefox has the "badge" setup that Chrome has, but in Chrome there is a plugin (puzzle) icon shown on pages that may have inaccessible flash elements. Normally if a page isn't working, my first attempt is to click the puzzle and say "Run plugins" or "Always allow on this site". It can be annoying to remember to do it, the first few times you may curse the site for being broken before you realize what's going on.
