Resolved Firefox Bug with Flash Upload Button

[Wes]

Due to an issue with Firefox 49.0.1 and Flash (including the latest version), the upload button on the forum posts appears blank white when you're using Firefox to post a new topic.This happens with all of our forum styles. The ability to upload files is not affected. Hopefully this will be fixed by Adobe and/or Mozilla soon. I'm looking into ways I can fix it from our end too.



Also please note that on XenForo, you can copy-paste images directly into your posts!

Aha, I found a temporary patch:

OK here's a quick fix without editing the SWF Uploader file:

Edit the template attachment_editor.css

Find:

.swfupload
{
position: absolute;
z-index: 1;
}

And add (in red):

.swfupload
{
position: absolute;
z-index: 1;
width: 0px !important;
}

Save and the problem goes away.

Reverted changes to attachment_editor.css and implemented other workaround by adding to EXTRA.css:

.swfupload { opacity: 0; }
