Page cache inconsistency across browsers

Ive done all my Wordpress development in Firefox and I am using a caching plugin called W3 Total Cache.

The only problem I'm facing is that in Safari and Chrome, my navigation is being reloaded each time a user works their way through the navigation, I understand this is how the web works, that assets and content are being reloaded with each click. But in FF, its perfect, the nav appears to stay in place while the navigation is extended underneath > see http://spunfilms.samuelcane.com/ then http://spunfilms.samuelcane.com/work and then that pages children. Have a look at the site in Firefox and then in Chrome/Safari.

Has any开发者_开发问答one got any ideas why I'm getting this inconsistency across browsers?

Is there a way around it?

Thanks, Red

By using W3TC plugin in Wordpress, I managed to optimize the site to make the page load almost instantaneous. My problem was that the plugin wasn't configured properly. I took a look at some other sites using the plugin and tried to configure it accordingly.
