Could be the the ability to comment is being removed, but existing comments will remain.
I don't know what's going on with Firefox, but on Chrome, I could still post new comments. If the ability is eventually removed, like what was done with the unhelpful button, existing comments will disappear. Amazon is justified in the removal, because they've gone out of their way to make the comments sections as useless as possible:
1) No longer is a number next to the comment icon, indicating a discussion.
2) No longer are reviewers and comment posters notified of postings.
The hit or miss ask questions section is allowed to stay. I say hit or miss, as whenever I ask a question, I'm messaged with responses saying "I no longer have it" or "I don't have it" or a response indicting someone's irritated or they don't understand the clearly phrased question.
