Rewsponding to an answer to my question

A little over a week ago I logged on asking a question related to the inability of the download I had made of the current version of Firefox to install on my new windows 11 Pro laptop. There were a couple of answers, the last of which was posted by James, who is identified as a Moderator. I made not of his response, logged out of the forum and followed his instructions. I found that he had accurately diagnosed the problem and had responded with a very successful answer. Over the following week I attempted several times to log back onto the forum and replying to his response to thank him for his assistance and let other forum members know that his effort was appreciated. At no time was I able to return to my question, find his response and properly thank him for his effort. Each time I returned to my question I was blocked from doing anything other than reading my question. I could not even access the replies.. That is not in the interest of the forum's users and is an insult to the hard working moderators whose efforts must be duly acknowledged and lauded. I suggest that some changes to this website are due and whomever the powers may be that make stupid decisions which maybe harmful to its users should be given the heave-ho and be returned to that unspeakable place from which they evolved. Thank you James. You did an excellent job and should be commended!
