Unloadpage
This utility simply removes all the page content.
Ideal to maintain tabs open with free ram.
Sometimes is needed to store page address location in tabs for the next start.
Before:
Page content is loaded as expected

After:
Page content was removed and the address field is still filled

Base Code:
var tounloads = document.getElementsByTagName("html"); var tounload = tounloads[0]; tounload.remove();
Test it here.
Click will empty this browser tab and let the address field completed.
Reload tab to get back the content (internet needed)
