Inline media uploader broken

[greuben]

Using FF4, on add new posts screen click on "Add an image" meida button, the "select files" button is missing and there's a javascript error.

c.defaultView.getComputedStyle(a, null) is null

The button appears if I reload the media uploader iframe

If we init the JS later, perhaps at body.onload instead of document.ready, would it bypass that bug?

Tried it, no change.

A silly hack to bypass this bug would be changing display: none to visibility: hidden. See 17329.diff​

The js error is fixed in jQuery 1.6.1rc1 but the "Select files" button is still not displayed with jQuery 1.6.1rc1

Seems fixed in FF 4.0.1, all thickbox popups with iframes work properly.

I'm using FF 4.0.1(Ubuntu), the problem still exists.

Confirming this error occurs in Firefox 4.0 on Win7.

A little less creepy hack is to use negative offsets instead of display: none. See 17329.2.diff​

Think the reason for this happening is that the swfobject DOM ready event fires before the jQuery one. Tried adding some delay in swfupload.swfobject.js that seems to fix this.

Add some delay to allow the flash uploader swf to load in FF4, fixes #17329
