Javascript Code to Disable “Select All (Ctrl+A)” and “Copy (Ctrl+C)” for both Firefox and Internet Explorer
This is useful in preventing outright copying of webpage content through keyboard controls like Ctrl+A for “Select All” and Ctrl+C for “Copy”. Just paste this code on the “head” of the html code - before the “body”.
