Great Add-on, new version buggy Rated 5 out of 5 stars
As a follow developer I think this product is great. I think your latest version has some major bugs though, I'm having the same exact issue as StelSi. It's completely messed up my firebug.
Upgrade to 1.5.6
There was a bad windows path bug that has been resolved in version 1.5.6. It is not public yet, but you can download a copy here: https://addons.mozilla.org/en-US/firefox/addons/versions/7943
