Downloading files for a particular type no longer prompts me for action, but simply saves the file. The application is set to "always ask" in Options, and in desperation I have now changed all applications so that none of them are set to save a file. Can't see anything in about:config or about:plugins, and am at a loss where else to look, Incidentally, I have tried changing the action to something else without any difference in behaviour - it just seems to be ignoring the options setting.
