177723 - [RFE] Cannot say "Run script to completion"

Status: RESOLVED WONTFIX

(Core :: DOM: Core & HTML, enhancement, P5)

Description

[George Russell]

The page has a number of scripts on it, which take a long to execute for certain
inputs. Every so often, a popup appears, asking to abort or continue the script.

I'd like to be able to 
a) Set how often such a popup should appear, from never to user defined times
b) Be able to turn such a thing off from the dialog

For an example, press the Fib button and enter 32 as a parameter.

Not an issue for the JS Engine, but for the browser embedding of
the JS Engine. Reassigning to Browser-General. Since this is an RFE,
setting severity as such. Compare these bug reports:

bug 13350
"DOM needs to police JS infinite loops, schedule garbage collection"
bug 30942
"Browser should remain responsive during most infinite loops"
bug 40848
"Other Mozilla windows should be responsive while one is frozen"
bug 51139
"ESC should stop JS in browser"


George: for comparison, how does IE handle the same situation?

Move all DOM bugs that haven’t been updated in more than 3 years and has no one currently assigned to P5.

We cannot give web developers full control over the user's computer resources. The modern dialog here is a lot less invasive however so if sites make it clear why they might appear slow there shouldn't really be a problem.
