1312276 - Flash - wmode="transparent" is not transparent anymore

Status: RESOLVED FIXED

(Core Graveyard :: Plug-ins, defect)

Description

[Toad]

Attachment: file-wmode.zip

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:49.0) Gecko/20100101 Firefox/49.0
Build ID: 20161019084923

Steps to reproduce:

This piece of code used to work fine in the previous Firefox versions (and still works on Chrome, IE, etc.) but it is no longer the case as the wmode="transparent" is not taken into account:

<object data="file.swf" width="100%" height="527" type="application/x-shockwave-flash">
<param name="quality" value="high" />
<param name="menu" value="false" />
<param name="wmode" value="transparent" />
</object>

Please see the attached file by running the html file in Firefox, then Chrome. You will see the difference in a second.


Actual results:

wmode="transparent" seems to not work anymore and so, the background color is not transparent.


Expected results:

wmode="transparent" should set the swf background as transparent.
