Can't use Firefox browser when I want to participate in the forums

When I'm using the Firefox browser-which I prefer-the bottom of the page in the forums states that I can't post or reply, etc.
I have to use Microsoft IE to participate.

Does this also have to do with the website update?

Thanks

Hi; I 'm replying from the bottom of the page (Quick Reply) and using Firefox which I prefer it as well (actually I can't use anything else). But I experienced what you mentioned once or twice. It should be update related.

Should have been fixed with new forum.
