Noemi, can you please retest with the patch I just attached to bug 1163945?  Thanks!

Hi,

I've just re-tested with the patch added to Bug 1163945 and the crash is not happening anymore but I'm still not able to load the page (step 6 in the description), the following error appears in the logcat:

E/Browser ( 1732): [JavaScript Error: "Error: Failed to load script (nsresult = 0x80004005)"]

It is same error as the one reported in https://bugzilla.mozilla.org/show_bug.cgi?id=1164100#c0. Since the crash is not happening anymore, marking this bug as duplicate of Bug 1163945.
I'll re-check the remaining issue once Bug 1164100 will be fixed and opened and new one if necessary.
Many Thanks for your quick fix!

Hi,

I've just re-checked this scenario once Bug 1164100 and Bug 1163945 have been landed and it works fine. I'm able to re-load the page. Thanks for fixing it so quickly!
