Great add-on - I'm a noob at this stuff but this saved me so much trouble!

This is such a great app. Couldn't image designing on Squarespace without it. In fact, I couldn't.

I highly recommend this extension! I design client websites exclusively on Squarespace, so it's a must have! I'm really glad it was developed for Firefox users. I recently reached out to the developer, Heather, with an issue because the extension wasn't working properly. She responded and fixed this issue SO quickly! Overall fantastic extension and great customer service!
