Ads only sometimes load

For the past few months on all my sites my google ads only load sometimes. I thought it was only me but my friend says it happens on my sites also.

On the toolbar it just shows the site to continue loading and leaves a blank space where the google ads should be.

You refresh and they usually show, refresh again and there gone, vice versa.

Really annoying, heres an example of one of my sites - http://texaschainsawmassacre.co.uk/

Any help is appreciated

 

It works fine for me
Maybe it due to less matched ads

 

Hi mate, I have opened your site and It was working fine with your website.
May be it was due to ads may not available for you in that time . In that case google will show gaps , if you have selected or social related ads.

 

Maybe you changed browsers or you have adblocker?

 

Thanks for checking guys.

It must be my browser(mozilla) which is causing the issue. I think im going to change to google chrome.

 

Ahh it must be because firefox has been freezing up on me and doing a lot of other stuff now. I switched to chrome and everything works now.

 

Maybe its something to do with your browser or Internet connection
