Impossible to give an answer in a certain thread

I can't reply to this post https://community.adobe.com/t5/back-room-ideas/automatically-lock-posts-after-a-no-activity-period/idi-p/13077104#comment-on-this

I hit the reply button and the page move to the top, not much ?

I use FF, on W10 uptodate both. I hit reply in different Adobe's forum with no trouble, including this actual thread, but not possible in the link named above ?

any idea ?

Thank you for looking into this, John.

I believe there is something rather strange going on in Firefox:

First I was unable to post so I posted here;

then I was able to, and posted here;

then I was unable to again, and posted here again, and found out that I was unable to post in another thread, to;

then I opened a new Firefox window and was able to post in both threads.

I am still unable to post in the original Firefox window which has 8 tabs open.

I believe I shall just have to close it.

Somehow I am back to being unable to answer in that thread again.

For a while I have tried in vain to post a reply to Claudio, and alternatively to the OP.

The OP has given a rather strange answer to Carlos.

Jacob, the Reply button works for fine me in that thread, both in Firefox/Mac and Safari/Win.
