browser stop script or debug script

When any browser hangs and finally a long time later comes up with the
question to stop or debug the script, I never want to debug.

Warning: Unresponsive script
A script on this page may be busy, or it may have stopped responding. You
can stop the script now, open the script in the debugger, or let the script
continue.
Script: https://news.google.com/?hl=en-US&gl=US&ceid=US:en:159

There's a checkbox for "Don't ask me again" and a button for "Continue" or
"Debug script" or "Stop script", where there's no real choice other than to
stop the script (and not ask again).

But it comes back the very next time I re-open the browser to that web
page, so I have to go through the whole charade over and over again.

What I want is that popup to never come up and for it to just default to
stopping the script but if the popup must come up what I want is to set the
timeout to just 5 or 10 or 20 or 30 seconds (whatever).

How?

The question has 3 choices: to stop, debug, or continue.

The 10 second script timeout is OK for some sites, but not for others.
When paying for something on the Web, for example, the online payment
site may be slow to react. If you stop the script, you won't know
whether the transaction has gone through or the state of your bank
account. In this case a reasonable person would click "continue" several
times to give it more than 10 seconds.

As described above, clicking "continue" is sometimes the rational
choice. The 10 second script timeout is OK for some sites but not
others. A rational person would want a longer timeout than 10 seconds
when, for example, it is his or her money at stake.

You have not said which browser.

An answer for one browser has maybe a 20% chance of being the answer you
need, and an 80% chance of being a waste of a person's time answering.
These unfavorable odds will not encourage people to answer you. For this
reason I will also not spend more than one line on saying "how".

For Firefox use the preference setting in bug 1101124, at your own risk.
