Forget the popup problem, not being able to post in FF and all the rest; NOW I can't even logon with FF. When I try I get the following: The page isn’t redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies.
I really think unfortunately it's a Firefox thing that we can't control. Hate to say it, but I've been using Chrome more and more.
Every few years one browser or another has an update and we have this issue. This year, it's Firefox. Typically they will release an update to the browser and the issue will be fixed. until then your choices are: 1. Use a browser other than Firefox. 2. Change your account settings at the forum to use the Standard Editor Toolbar instead of the Rich Text editor You can do that in your (account) preferences Scroll and hit save after... Note that making this change will result in a simplified reply editor.
