I use firefox and it seems to work OK.

What might help is to flush out your cache. Also delete the history.

Tools Options Privacy Clear your recent history - Cookies etc.

The cookie used by NE on your PC to identify you might be corrupted or whatever, and need replacing. Clearing it, then re-logging in will replace it. Cookies can all be deleted or individual ones.

That may help.

Also shutting down and re-starting a PC often helps with all sorts of problems. Simple but true.

Let me know if it does not improve after a day or two.
