720667 - Crashes during tab switching when dom.ipc.plugins.enabled.npswf32.dll is set to false

Status: RESOLVED WONTFIX

(Core Graveyard :: Plug-ins, defect)

Description

[beLIEve]

Firefox 3.6.23 - 3.6.25 crashes under the following conditions :
- dom.ipc.plugins.enabled.npswf32.dll is set to false : user_pref("dom.ipc.plugins.enabled.npswf32.dll", false);
- tabs are being switched from/to the tab that is loading a Flash object.

Steps to reproduce :
1. Goto about:config and set dom.ipc.plugins.enabled.npswf32.dll to False
2. Open 2 tabs.
3. On the first tab, browse to your favority stock on Google Finance, say, http://www.google.com/finance?q=NASDAQ:GOOG
4. Wait for the page to load. The last object to load would be the Flash object that displays the stock chart.
5. Refresh the stock page. Before the Flash object is loaded, quickly toggle between the 2 tabs and Firefox should crash. Repeat this step if it doesn't.

Firefox 3.6 is only updated with security updates.
Update to Firefox 9 then report back.

Firefox 9 does not use this preference, so the problem does not exist there. Have also tried injecting the configuration in and there's no crashes.

Have you tried with dom.ipc.plugins.enabled set to false?

Yes, been there, done that, before I manually injected that Preference in. No crashes.

Thanks Uncle Scoobi :)
