gBack: code for making the opposite of webcompat to github and come back to the issue page. This can't work as a bookmarklet because github is HTTPS. We need to make it as an Addon extension (unfortunately less universal).

gBack.js

javascript:
l=document.location;
if(l.origin==='https://github.com'){
  githubPathname=l.pathname;
  pathArray=githubPathname.split('/');
  webcompatLocation='https://webcompat.com/'+pathArray[3]+'/'+pathArray[4];
  document.location.href=webcompatLocation;
}
else{
  alert('not%20github%20here');
}
;
