Starting several days ago, I can no longer download from macupdate via Safari or Firefox. If I try to download software directly from a developer's page, that doesn't work either. Safari gives me a new tab with the status bar message "Failed to open page (see Activities window for details)." The activities window says "Plug-in cancelled." Hunh? What plug-in? What do I need to do? In Firefox, I get a new tab with the URL of the zip file, and the status bar says "transferring data from _____," yet no data transfers, the download window doesn't open, and the little circle (preceeding the tab name in the tab bar) indicating that page download isn't complete just goes around forever. Please, someone.... Thanks.
