Can you look in your browser console and see if there are any suspicious messages when you try this testcase with e10s?

Comment 3

[arni2033]

I don't see any messages in browser console with all types of logging enabled when I load the testcase AND when I click Flash objects


STR_2:
0. Install up-to-date Flash.
   Open about:config, set "plugins.rewrite_youtube_embeds" -> false
   Open about:addons -> Plugins, set Flash to "Ask to activate"

1. Open "data:" URL in the form above

2. Click "Activate Adobe Flash" in any of 2 Flash objects

AR:  No visible action. There's no plugin button in urlbar
ER:  Popup notification (panel) should appear
