OK I did an upgrade on Firefox, now when I go to this forum, I click on a topic from the top menu and it doesn't open it.
I sign in, then when I open a topic by clicking on it (below the aforementioned top menu), it opens the topic, but I am no longer logged on.
I log on and it kicks me back to the front page. Click on a topic and it logs me off.
Internet Explorer works ok, so I know it has to be an issue with Firefox.
Any ideas?
