NLB login error

Problem

I registered for a NLB membership recently. I tried using my NRIC to login online at the NLB website, but that did not work. I presumed that maybe I needed a web login. I went to a library the next day and using a E-Kiosk I created an online login. I came back home tried that and I still could not log on.

Solution

To diagnose the problem, I tried the login using incognito mode in Chrome and it worked. By using trial and error I found that it was one of my extensions that was causing the error (and not cookies). Turned out that the Ballloon extension was strangely causing this error. Uninstalling it made my NLB login to work.
