0 Trouble at the Google Mill

Just when I thought that all of my problems were behind me, I now find that Google will not allow me to leave comments on some blogs. Over the last few days I have left several comments on several blogs only to see the comment disappear when I press the publish button. The blogs that I am having problems with have the reply option in the comment section. Husband, who is a computer wonk, has looked at the problem and can not work out how to get around it. We use Firefox as a browser and it may be that Firefox has instituted an update which is causing the problem. If anyone can explain in words of one syllable how we can resolve this issue I would be grateful. I fear that at the moment Google has gone beyond my computing skills, but I always have plenty of things to do. So maybe I am going to have to occupy myself elsewhere.
