I have Thunderbird 17.0.5 and have had several RSS feeds pulled into a folder each day. About three weeks ago, the feeds stopped looking like nicely formatted web pages to raw, unformatted HTML. The images are not displaying (but the HTML is ok.) "Old" files that displayed properly before now don't display, so it's not a problem with the delivered data. I've fiddled with all sorts of settings to get things back to "normal," but to no avail. Does anyone have any ideas how to fix this?
