Dear Firefox Community, I can't create subject or new post on AMD Community forum. I mean this website: https://community.amd.com/ This can be problem with firefox because before update to version 91.0 I had not any problem. I think that this is problem with cookies because when I open community.amd.com website in private mode I can create only one subject or new post. If I want to second subject or post I can see information like this: "Post flooding detected (user tried to post more than 1 messages within 600 seconds)". Like I said when I want to create second subject or post this is not possible. To solve this problem I must log out from the website next exit the tab and open new one in private mode, log out again and I can now create again but only one post/subject. This can be also problem with new version of firefox 91.0 because before update to this version I had not any problem. I think that this is problem with cookies. Can you tell me if you have also this issue? Thanks.
