Tab cloaking
About:blank cloak
NOTE: Refreshing the page when it is about:blank will make it deactivate.
About:blank cloaking is a recommended tool since teachers use
relay
to block specific sites. (An example is google sites.)
Clicking the button will redirect you to this same page, but the
link is about:blank.
This is useful if the teacher is blocking this site.
