OK, I'm a newbie with Firefox. I have been developing my website with HTML, CSS, and JS using the FF browser. However, I am having a terrible time getting it to save correctly my files. Even if I click individually on the SAVE icon for each HTML and all three CSS style sheets and then use the SAVE PAGE AS option, when I reopen the file it has reverted to an earlier version. I figure this is PEBCAK and does anyone have a suggestion on what I am doing wrong?
