We are currently aware of an issue with firefox browsers that do not allow for users to log out, when your browsing in our main website sections and not the forum.
We are working on trying to fix this, and we do not currently have an ETA of when this will be fixed.
We also kindly ask if you experience this issue to let us know by either our support section, or live chat or by replying to this thread!
We are sorry for any inconvenience this has caused.
