Since updating to FireFox 3.6, I notice that the browser is adding 1 pixel of spacing around a flash movie which cannot be removed by CSS properties:
border
outline
margin
padding
float
position

You can see the problem here: http://89.16.185.23/ (please note that this URL will change in the near future).

Many people are reporting the same issue:
e.g. https://support.mozilla.com/en-US/forum/1/568476#threadId621132

In my example above, the flash movie is being inserted using the flash satay method.

I am not sure if the problem is limited to the Mac OSX version of FireFox 3.6 or not.

This is a very important issue to many developers since we are experiencing complaints from clients who cannot understand why we can't fix the issue.

Reproducible: Always

Steps to Reproduce:
View flash movie in web page using FireFox 3.6 Mac OSX
Actual Results:  
1 pixel of spacing is added around the Flash movie

Expected Results:  
No spacing around flash movie

I confirm, this bug (as i think) appeared right after updating to 3.6.
I have a <div> and an <object>, both of the same size, and FireBug confirms it. So <object> exactly fits the <div>. I use box-shadow property on the <div> element. On version 3.5.X the shadow was exactly around my flash, but in 3.6 there is 1pixel top-left offset between flash and shadow. But FireBud doesn't show any changes in the layout.
An example can b found here: http://video.interzet.ru/video.php?id=14064 You have to click on the monitor icon under video description and flash will appear.
The issue appears only under MaxOS.

I confirm the bug as well, using FireFox 3.6.9 on MAC-OSX 10.5.8.  One pixel left generated next to flash player.

Unfortunately, in spite of your report, the bug has not been corrected in version 3.6.10. There's still that ugly pixel on the left of the swf. I'm starting to suggest my Mac costumers to migrate to Safari, at least to view their own site.

none of the links work for me, so lacks testcase.
if you still see this problem please add a testcase
