844465 - charset=iso-8859-1 parameter causes blank white page flash

Status: RESOLVED DUPLICATE of bug 844461

(Firefox :: Untriaged, defect)

Description

[geniusjjf]

Every page with <meta http-equiv="content-type" content="text/html; charset=iso-8859-1"> invariably rendered with the empty white flash page before rendering the actual page. Only noticeable on dark background pages.

However, every page with <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> rendered perfectly and instantly with absolutely NO white page flash.

I tested all this on my own websites and it worked every time for any size page. As long as it contained charset=utf-8 all is well; FF19 renders smoothly with NO white page prior to rendering. But if you code your page with a "charset=iso-8859-1 parameter, FF19 invariable displays an empty white page before loading the actual page. So it appears that the v19 core is choking on the "iso-8859-1" charset parameter and spitting out a white page before it renders the page
