This bug has been filed for some prior versions, but still not fixed. There are some bad pages, that contain <script>while(true){alert('whatever');}</script>. If I open such a page, I can't close the browser because of endless alerts, so I have to terminate it, using console, losing all the opened pages and the data, I have typed in the forms, dropping sessions, etc. I think in every alert there must be an option to stop the JavaScript on the page, so user can quit the endless loop. I think it must be fixed in next version, because it's very easy to distrupt normal user's work because of that.

Reproducible: Always

Steps to Reproduce:
1. Open Notepad
2. Write "<html><head><script>while(true){alert('OMG');}</script></head><html>"
3. Save it as html page
4. Open it
Actual Results:  
I can't close the browser, and I must terminate it, losing everything I opened, written, etc.

Expected Results:  
There should be a button or checkbox "Prevent this page from opening additional windows" or "Stop JavaScript on this page", so I can quit alert loop.

I know, I post the duplicate, but this bug has been posted for many prior versions, but still not fixed.
where is the duplicate?

Do not post duplicate bugs, It doesn't help to fix it and it only waste our time.
marking invalid, search yourself if you want to know the original bug number.
