Mysterious new tabs opened by content affected by rewrites since nsIContentPolicy disablement
In Google Reader:
- View an RSS feed in List view
- Click on the title of an entry that contains a YouTube video to expand it
- Click the title again to close the item
- A new tab automatically opens in Firefox which contains just that video.
This started happening with Firefox 7 and HTTPS Everywhere 1.0.3. This appears to be caused by the Google Services rule, since when you disable this rule, this no longer occurs.
