Before I updated from firefox 29.1 to 30.0, it was always possible to save/download internet sites with save as option. The german domain heise.de is one of my favorite internet sites. When I activate the offline mode in firefox he won´t save/create the .htm file. Reason is I won´t make big traffic on my network to save internet sites. I wish to download them at the first time I load them into the browser.
