CTRL-S -> SAVE doesn't work after editing saved-to-local webpage

[Budi]

I did CTRL-S -> SAVE to save a webpage and close it and the browser altogether.
Then I reopen Cent, reload the local-saved page and go into developer tools and modified some URL there..
But when I next did CTRL-S -> SAVE and close it and reopen it, the modification gives no effect at all.
Simply looks like the save command not work at all.. please help me I really need this capability.. Thank so much in advance

In order to modify the HTML files, you have to use HTML editor.
Changes via developer tool only LIVE IN MEMORY, and will disappear after you close the browser.
