There seems to be something indicated on the toolbar with a "3" that might mean 3 files were blocked. Can you click that button to see what is going on there?

More generally, if you open the developer tools (Command+Shift+i or F12 function key), there are two places to check for loading issues.

(1) Network Monitor (the Network tab in the developer tools)

Reload the page to start tracking the success to requests. Any problems loading the CSS files?

(2) Web Console (the Console tab in the developer tools)

Does Firefox give any explanation for not loading or not applying CSS files?

The site shows quite differently in my browser so the issue may be related to your browsers settings or extensions.

I am aware it works fine on some other people's machines. However, it used to work on mine perfectly. Then, after doing some minor updates on the site, it stopped showing correctly. It has happened before, but cleared after a day or two. However, this has been over 2 weeks now and I have re-installed Firefox and cleared the cache but it is still not displaying correctly.

Can you offer a solution, apart from going over to Chrome or Safari?

I prefer Firefox, need it to work on my own website.

jscher2000, I think you are onto something. I disabled the 3 adblocker warnings, but that made no difference. However the Console tab has 4 warnings:

Any thoughts on what I need to do?

​

If you open one of those image URLs, an HTML page likely will appear with some kind of error message.

Maybe you changed it already, but I'm not seeing "cache" in the URLs used in the page so I'm not sure why your Firefox is trying to retrieve those.

The issue is only on my Homepage as all other pages are viewing OK.

The 4 warnings I had yesterday on the Homepage are now 5 today. I viewed the various Errors, Warnings, Logs etc tabs, it went up to 8 but, when I finished this message it is now have 11 warnings!!

This is crazy! PLEASE can anyone help?

I just noticed a the word 'autoptimise' was mentioned in each in each line of error code. I checked my plugins and found the culprit was the Autoptimise plugin – eventhough it was switched off. When I deleted it, the problem disappeared. Problem seems to have been solved :)
