Just found a really short JavaScript code inside a html document that will on Firefox for Windows/Linux no longer let you use your OS. Also android gets completely laggy and needs a force restart.

(I'm new to JavaScript)

@Kreischo http://eazyclient.de/kekse.html tested it on my android, Windows 10 and on a linux

@Kreischo accidently klicked that link, had to restart android xD

@Kreischo didn't have a better name...

Btw "mailto" is the only url on Windows that doesnt need a confirmation of the user to open a Program. "sms" does the Rest for android and also creates many popups on Windows.

@Kreischo i sent this to a friend... He was that poor linux guy😂

@Kreischo hmm ok... well for me it just opened it🤔

@daksh it is kind of a while true loop but it opens up an email and sms Program every time.

@Kreischo on Windows Yes
on android no

@daksh it is:
onload {
location.href = "mailto:1;2;3;4...";
location.href = "sms:";
location.reload();
}
The numbers after mailto go on that's because Windows Mail read this as an array of adresses to send the Mail to. This gets Windows even more laggy. I dont know if it would produce a different result if you use while (true) and not location.reload();

@Kreischo using while (true) and android's vibrate function i created another thing that completely messes around with the Vibration Motor even if you close Firefox...
I will test the mailto-thing tomorrow.

@daksh thx for that, i just started javascript. Opening new tabs seems like it triggeres the popup detection so nothing happens :/

@Kreischo whats with mc?

@EaZyCode Chrome Custom Tags dont't lag on Android

@Kreischo oh you know me?😂

@Kreischo oh xD

Tried on my windows 10 mobile. Nothing happened. 😎

@ravik with Firefox?

@EaZyCode edge

@ravik this is a Firefox bug it does not work with edge, IE, Chrome...

..... I should learn to read properly.
