loading a hi res picture on firefox causes this white background that fills from the top to the bottom. Now my internet is really good but on 4chan (with 4chanx) even 1 mb pics do this but it's like a split second so it doesn't bother me that much atleast on chromium browsers since it's transparent not a white background. I read that this has been a bug for years on firefox but couldn't find a fix (at the very least make this whit shit black but transparent is preferred). I should mention that transparent pngs load like in chromium
