Rated 5 out of 5 stars

An indispensable tool for any web designer! I have used this extension for years and it has worked flawlessly. Alas, I have not been able to install due to lack or SeaMonkey support but that does not diminish the awesome abilities added to your browser and how it makes web design and layout a lot easier. Worth every dollar of support asked by Kevin and highly recommend financially supporting this extension if you use it!
