There are mixed reports in this thread — sees the page stall in Internet Explorer while others (notably ) load it instantly, and and noted browser-dependent differences. That pattern usually means the problem is conditional or environmental (client-side configuration, network/proxy, or a particular resource the site pulls in) rather than a simple HTML bug. The first step is to isolate which side (client vs server) and which resource is slow.

Reproducible checks to run now:

  • Capture a network timeline in the browser dev tools and reload; note any requests that take a long time or never finish.
  • Start IE with add-ons disabled to rule out extensions: run iexplore -extoff.
  • From a command line, compare server responses with different user agents to see if the server replies differently: 
    curl -I -A "Mozilla/5.0 (Windows NT 10; Win64; x64) Chrome" http://example.com/
curl -I -A "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)" http://example.com/
  • Try the site from a different network or machine (or via a smartphone on cellular) to rule out local proxy/ISP/antivirus interference.

What to look for and quick fixes:

  • Any slow request to a third-party host (ads, fonts, analytics) will hold rendering in some browsers; if found, load it asynchronously or add timeouts.
  • Very large cookies or long redirect chains can slow server processing for certain clients — trimming cookies or fixing redirects helps.
  • If server-side logic is delivering different content by user agent, add logging (response times and UA) and serve the same lightweight assets to all browsers when possible.

For site operators: add timing headers or server logs per request, compress assets, defer noncritical scripts, and avoid user-agent gating. These steps turn the “works in one browser, slow in another” symptom into actionable data so the real culprit can be fixed.

I checked out the site in Internet Explorer in addition to in Mozilla Firebird. Just as you said, it loaded fine in Firebird but IE didn't like it very much. The HTML code doesn't look malicious at all, so I don't know why it wouldn't work.

The only thing I could think of is that server-side there is code to display different things depending on the useragent. (i.e. what browser/os is being used to load the page). This is plausable and I've seen it done before. I just don't see why it would be done in this case.

In addition, what gave you the idea this site was in php? I don't see any files ending with a *.php extension?

The site is including JavaScript files when loaded, and they're probably using JS commands that cause an error in IE. HTML seems fine, and even if it wasn't, it would stop the loading after a few seconds no matter how bad it was. It's definitely bad JS, or an outside resource that doesn't like IE. I doubt that they're twisted enough to purposely make IE users suffer.

I'm pretty sure it's in PHP because I did see some pages with a PHP extension. I also saw pages using the PHP session IDs to track user sessions.

Took about a nano second to load. Using IE.
