Show HN: A stupid hack to crash tab and/or browser

Well, now I have a tab that I cannot close. The whole browser is working correctly except for that tab.

Edit: Chrome, osx

Edit 2: Since I never close my computer and never close my chrome, I've pinned the tab so it's smaller. You have plagued my life for ages.

No crash here. After a couple seconds of grinding Firefox prompts to kill the script.

Linux Mint 17.1 Firefox 36.0

So it seems I am the weird case.

Ok. Thanks for telling me.

I found this out randomly when testing what can and what cannot be on this handler and how gracefully do browsers handle it. It seems that it's not that easy.

On OS X Mavericks 10.9.5 with Safari 7.1.3, it didn't do anything but show a beachball after hitting refresh, but I was able to close the tab without trouble or any detectable negative effect on my browser, etc.

Chrome on Linux doesn't care either, but cpus at 60-99%

At least on OS X, Firefox is as well behaved as you might expect when forcefully triggering an infinite loop on beforeunload.

Interesting.

So it might be a Linux issue. I have reported it anyway.

ran on macbook pro in chrome. tab went unresponsive for a few seconds when i hit back arrow. waited a second, hit x and a couple seconds later it closed.

OK, it might be a linux thing

I have submitted the thing to bugzilla and chrome bug thing
