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: 
```
What worked for me is to reset the fiddler https certificate and recreate it.

Fiddler version V4.6XXX 

Fiddler menu-> Tools-> Telerick Fiddler Options... 
Second tab- HTTPS-> Action -> Reset All Certificate

```

Once you do that, again check the check box(Decrypt HTTPS certificate)
I had the same problem, when i disabled chrome extension called **ZenMate Proxy extension** that fixed the problem
