I can reproduce and following errors show in Error console. Error: LS_FqR is not defined Source file: http://www.beursduivel.be/scripts/assets/javascript-asset-0005.js Line: 33 Error: attempt to run compile-and-go script on a cleared scope Source file: http://www.beursduivel.be/scripts/assets/javascript-asset-0005.js Line: 33 Regression window(m-i) Works: http://hg.mozilla.org/integration/mozilla-inbound/rev/b727463566a1 Mozilla/5.0 (Windows NT 6.1; WOW64; rv:9.0a1) Gecko/20110820 Firefox/9.0a1 ID:20110820184005 Fails(blank page): http://hg.mozilla.org/integration/mozilla-inbound/rev/857f058efa56 Mozilla/5.0 (Windows NT 6.1; WOW64; rv:9.0a1) Gecko/20110820 Firefox/9.0a1 ID:20110821013315 Pushlog: http://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=b727463566a1&tochange=857f058efa56 Suspected bug: Bug 679971 And if set general.useragent.override to "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/14.0.835.202 Safari/535.1", it seems to work properly in Firefox9.0 and Aurora10.0a2 and Nightly11.0a1 . So I think that this is the Site problem and this may be TE.

http://www.beursduivel.be/scripts/assets/javascript-asset-0005.js At least jquery 1.6.2 uses navigator.taintEnabled for browser detection, Recent versions don't. So the above script file needs an update. uTest, can you contact the webmaster?

> At least jquery 1.6.2 uses navigator.taintEnabled That's wrong, it's actually "jQuery UI 1.8.14" Recent version is 1.8.16.

jQuery UA 1.8.16 seems unaffected.

Worth a release note?

uTest, any updates? Is this working meanwhile? Have you or any one else contacted the webmaster?

We're backing out bug 679971...
