In some places bookmyshow.com gives you Content Encoding Error. I am using firefox 3.0.11, but still not able to open the site. To open the webpage you have to remove content encoding in firefox. Just follow the below steps:
1. Type about:config in your browser
2. in the search bar there search for “network.http.accept-encoding”
3. Right click on the key and select modify and remove the data and leave the value compress.
You done with the things just type www.bookmyshow.com in your firefox.
