Code review comment for lp:~rpadovani/webbrowser-app/settings-page

Thanks for the suggestion Olivier, I implemented that.

BTW, we should take a look to the function looksLikeAUrl(). It checks if tld.length is < 5 (.match(/\.[a-zA-Z]{2,4}$/))
Now TLD could be very long[0], so we should remove that restriction (also if they aren't used so much at the moment, the only one I know is com.google)
