Rated 3 out of 5 stars
This is a great tool. However, the latest update for either FireFox or this tool has a glitch which will only open the tool results in a tab instead of new browser window. That is a big drawback when trying to compare the results to the actual web page source. Instead of having them side by side I have to flip back and forth between tabs. That's a pain. But, the tool does work well.This review is for a previous version of the add-on (188.8.131.52-signed).
