It has never worked since I started going to icloud.com/#photos a few weeks ago to manage my photos and videos online. Everything else on icloud.com works though, just the Photos is the problem with NS.
I keep getting this pop up error saying "Photos has stopped responding", here's the screenshot of that pop up.

I know NS is causing this issue since as soon as I disabled it and restarted Firefox, my iCloud Photos worked just fine, for the first time ever. That, and it works fine using Chrome too, but I don't like using Chrome.
It has to be something in the Options/Settings that's causing this glitch. Please tell me what I can do to resolve this issue.
Thank you,
Lee
