Question: Happened to come across an e-commerce website today, [Harrods.com](http://www.harrods.com). I thought the scrolling effects that they are using (non-mobile site) are really cool. The content and backgrounds seem to scroll at different rates. As you scroll the navigation selector moves under the appropriate category as well.

I tried going through their source to figure out how they are doing it but didn't have any luck. I saw that they loaded up the background images in a `homeImages` variable, but never found it used in a script. Is this something that can be accomplished purely with CSS? Is there a name for this effect I can search on?

Answer: 
I had the same issue with Firefox. The solution was to set the proxy settings to "system proxy settings". Fiddler can only capture traffic that goes through its proxy server. Capturing was stopped because a few days ago I was tinkering with the Firefox proxy settings for another project.

It follows that using Chrome you should also check the browser proxy settings in case of problems with capturing traffic with Fiddler.

I too faces similar problem, but once I did the below settings, everything was working fine(While working on other application, I selected 'No Proxy' setting in browser which I forgot to revert.Hence, got this problem)

* In Fiddler, Goto **Teleric Fiddler Options->Gateway** , then select 'Use System Proxy (recommended)' radio button and click on 'OK' button and restart Fiddler
* In your Browser(for ex: firefox), Goto Options->Advanced->Network->Settings then select 'Use system proxy settings' radio button and click on OK
* Now try accessing any URL from that browser, and observe they are being recorded in Fiddler(If you have applied filters, even they will start working)

Hope this helps..
