Redirects broken in latest Firefox nightly.

[KWierso]

In today's Minefield build, NoScript seems to be blocking redirects on pages.

I'd suspect bug 313646, but I haven't had a chance to test a previous hourly prior to that landing.

I can confirm the same behavior. With Noscript 2.0.3.1rc4 and the 20100917 build of the latest Firefox 4 nightly, I can no longer access any of our internal sites which use an Apache pass though proxy front-end for RSA authentication. As soon as the RSA auth succeeds instead of the redirect going through, we're brought to a blank page that just says "redirect" and stops.

Still working fine with 2.0.3.1rc4 on Firefox 3.6.10.

Thanks.

Well, I installed an hourly from the build just before that bug's push, and redirects are still broken.

Going back further now.

Okay, did some testing.

KWierso which is the last hourly build that worked?
my thoughts would be the async api must have changed somehow, but now im not so sure...

Thanks much for identifying this. Georgio, any idea of anything in:

http://hg.mozilla.org/mozilla-central/p ... f07a0a036b

changeset that stands out as causing problems with NoScript redirection? Anything I can do to help diagnose?

Thanks.

Disabling jaegermonkey doesn't fix it, either.

Going through with Firebug it seems that on the nightlies it stops on any messages with the 302 status code. When using 3.6.10 with Firebug, the 302's are getting acknowledged, followed by the subsequent 303's which load the redirected resources properly.

Confirmed, and the culprit has nothing to do with networking.
Strange as it may seem, it is due to an apparent bug in the Array.slice() generic method and/or in JavaScript prototype chain (Array specific?)
I'm checking how wide the fallout is, beside this redirect issue, and providing a work-around in next dev build.

[KWierso]

Lots of changes regarding strictmode in that merge. Maybe related?

EDIT: Really need to remember to refresh before posting...

Fixed in latest development build
