XSS Warning Message

I was wondering should I be worried that I had a message appear saying "NoScript filtered a potential cross-site scripting (XSS) attempt from [https://www.google.com]" when I logged into my gmail account and I was in my inbox?

I logged in today over 15 times and every since I have been using my gmail, I have never gotten this message.

I forgot to mention that the error message only appeared when I was staring at my inbox, it wasn't when I was logging in.

I use Gmail and haven't seen that.

Can you open the Error Console (Ctrl+Shift+J) and copy the message here, inside [ code ] tags?

After I got that message, I logged out and close Firefox. The only thing I remember is in the Error Console, there were 2 Warnings that had from DOM somewhere under each warning.

I tried logging in again after I logged out and cleared my browsing history, but I haven't been able to repeat even after 5 times.
