Don't use this unless you want to lose your account information :)
Just a quick heads up to anyone looking at this, last time I tried to use this on a previous version, my account detail for everything I was logged into on chrome, including emails, League, steam, and other websites and such, got leaked, and my accounts hacked. Don't use this unless you want to lose your account information :)
edit:
Rethinking this post, I can't say for a 100% guarantee that it was this that caused it, but it at least felt coincidental that the button seemingly did nothing, and then within the next 24 hours my accounts were accessed. Use this at your own risk, be careful.
