Will this also prevent loading downloaded .swf files into Firefox? This is useful for running Flash games, which tend to work best in the browser (some media players also support loading Flash files, but their hotkeys tend to conflict). Obviously if we get to the point where we stop supporting Flash altogether this use case will break anyway, so mostly asking for clarification. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
