I can reliably reproduce the issue, even from outside of Brazil.

I’m seeing the following related logs when browsing to http://www.hsbc.com.br :

So it appears the page is trying to load youtube flash videos (of mime type application/x-shockwave-flash), and oxide transforms that into a download request. Not sure whether this is a bug in oxide, or if this is correct but the browser should ignore download requests for mime types it knows it can’t handle.

The youtube videos are embedded in hidden iframes whose 'src' attribute is set to the flash video player. E.g.:

<iframe id="ytplayer-programa-de-fidelidade" width="540" height="340" src="http://www.youtube.com/v/4ZA2CH7150Y&amp;hl=en&amp;fs=1&amp;rel=0&amp;border=1" frameborder="0"> </iframe>

I linked a branch that fixes the issue, but I’m still unsure whether this is the correct approach, or if the issue could be addressed in oxide (so that we wouldn’t get the download request in the first place). Adding an oxide task to clarify this.

It is the expected behavior from Oxide. At the content level, the resource handler checks if the mime type of the response is a known default one, if not it tried to find a plugin for it and if not it forwards teh request to the download manager.
