Can you give some examples of where hover is not working? Typically Firefox would follow a site's directions for any special styling to apply when you hover over a link, and display the title of the link if set by the developer. Fancier things generally require attaching some JavaScript to the "mouseover" event. If that's what's missing, make sure JavaScript is enabled on this tab: orange Firefox button ''or'' classic Tools menu > Options > Content If you use the NoScript extension, make sure to check its menu for any script sources you might be blocking; many sites use more than one domain for their content. ---- When Flash is not working do you get any error messages? Blank white space or blank black space? There is an update for Flash available (Flash 11.4); that might help. Other info on Flash: * There are/were some compatibility issues between Flash 11.3 and some Firefox add-ons or settings. Could you see whether anything in this article helps: [[Flash 11.3 doesn't load video in Firefox]]. * You might also consider disabling the new protected mode in Flash 11.3, since that feature is currently being debugged.
