I have been using my HP laptop and XP for many years and about 6 months ago I switched from Internet Explorer to Firefox as my default browser. All was good until a week or so ago. Now when I try to access LinkedIn with Firefox, LinkedIn doesn't recognize me in any way. I don't even get an error message saying that either my email or my password is wrong. It just gives me a new LinkedIn sign-on screen as if it was the first time I was signing on. If I use IP, it works fine and I can access LinkedIn just fine. Help!!!!!!!!
