Warning: Unresponsive Script??

[ALB]

Hi there,
I just downloaded the phoca gallery and keep getting this message popping up -

A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.

Script: chrome://browser/content/browser.js:7489

Doesn't matter if I click continue or stop scrip, it continues to show up. What does it mean/what can I do?

Hi, not sure what this should mean, do you have a link to live site where this occurs?
