Must I update my trusty Firefox 38.0.5 in order to attach files and images to a post? The icons over the post editor are not helpful for this task. Is there a "standard" paperclip symbol somewhere that is the interface for attachments? I can't get any of the icons that look like they might function as "attach image" to do that. There is icon of a mountain, a icon of a piece of film, and icon of a "+", and an icon of a camera. As far as I can tell, none of them perform the simple function of attaching a image or other file that's on my computer.
