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: 
1. Use Help > Troubleshoot Filters to make sure the traffic isn't getting hidden unexpectedly.
2. Look in the **Log** tab to see if there's a note about Chrome Group Policy hardcoding the proxy.
3. Update your question to mention whether other browsers' traffic is captured.
4. Visit `http://localhost.fiddler:8888/` in Chrome; What if anything do you see?
5. Visit `http://127.0.0.1:8888/` in Chrome; What if anything do you see?

If you find that steps #1 - #4 don't show anything, this means that Fiddler is unable to set your system proxy information; this might be caused by security or VPN software. (Group Policy can also prevent setting, but Fiddler will *usually* warn you if this is the case).

When Fiddler is capturing, click Tools > WinINET Options > LAN Settings and see whether the proxy is set properly (should point at `127.0.0.1:8888`). If not, you might try running Fiddler elevated (as Administrator) to see if it makes a difference. It *may* be helpful to collect a trace using SysInternals' Process Monitor tool, filtered to **Registry** operations on the **ProxyServer** registry key.

If step #5 doesn't show anything, this means that you have a firewall or some other software interfering with connections to Fiddler.
Russian, this info for you!
Fiddler didn't capture Chrome traffic because I had installed Antizapret Chrome addon for access blocked by Russian government sites. I removed it and now all works.
