Avast Online Security not available with Firefox 42.0?

Avast Free Antivirus / Premium Security

I am using Firefox 44.0.1, I believe it is the 64 bit version.
If Avast Online Security 10.3.3.13 is enabled it causes causes http://ceploitips.com/shopkick-barcodes-scans
to display the comments at bottom of page incorrectly.
Do you know why?
What is the fix?

You are using an old version of avast - only the latest version of avast (11.1.2253) has a 64bit version of AOS add-on. Latest version of AOS is 10.3.3.39, not as you report 10.3.3.13.

If your firefox is a 64bit then the AOS with your old version of avast and old version of AOS shouldn’t work at all (shouldn’t install).

So I’m somewhat confused if your firefox is 64bit or 32bit.
