Often times I want to get a file from a website, but I cannot right click on it and do "save * (image) as" because the creator of the site has disabled this feature. In comes Firefox. Simply right click on any page and scroll down to view page info.
Once inside the "view page info" box click on the "media" tab. From here you can download any media items on the page you are currently viewing including pictures and embedded movies. Highlight whatever it is you are after and click "save as."
