For some reason, free code camp is freezing everytime I go to the “Profile Lookup” challenge. All the others before it seem to be operating fine. But my mac just stops in its tracks when I get to that page.

Thanks for any suggestions.

It sounds like you may have accidentally created an infinite loop. You’ll need to manually fix your browser by deleting the solution from your browser’s local storage: [http://forum.freecodecamp.com/t/clear-specific-values-from-your-browser-local-storage/19128](http://forum.freecodecamp.com/t/clear-specific-values-from-your-browser-local-storage/19128)

Please let me know if I can be of further help with this.

Dear Quincy

When I open the developer tools window, I don’t see a “Resources” tab. I’ve got most of the others shown in the Chrome example.
