768771 - Firefox hangs on page load when Shockwave Flash 11.3.300.262 plugin is enabled

Status: RESOLVED DUPLICATE of bug 767075

(Core Graveyard :: Plug-ins, defect)

Description

[i.am.feefee]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:13.0) Gecko/20100101 Firefox/13.0.1
Build ID: 20120614114901

Steps to reproduce:

Recently upgraded Shockwave Flash to 11.3.300.262 and Firefox to 13.0.1. Restarted Firefox.
OS is Windows Server 2008 R2 64-bit.


Actual results:

After restart, Firefox crashed/hung when loading any page. Tried for several pages with and without flash on the page - all pages cause firefox to hang. The only workaround to this problem is to disable Flash as a plugin. The crash happens regardless of whether the java plugins are enabled or not.


Expected results:

Page loads as normal. Firefox does not become unresponsive

The culprit is surely the new 'protected mode' introduced in Flash 11.3, you have to disable it.

Oh, and I see you're running FF13 on Win Server 2008. Likely a dupe of Bug 767075.
