PerfectPixel by WellDoneCode (pixel perfect)

I got a problem using this addon ERROR: Cannot open filesystem.\r\nPlease use Storage…ode.google.com/p/chromium/issues/detail?id=94314 When I try to upload an image nothing happens, it looks like image is trying to upload, but in console you get this error. I tried to remove and add this program, but it didn't help. Maybe someone had the same problem and know how to fix it. because alternatives are not as good as this one ...

This is the most useful extension for my work, our designers demand "pixel perfect" layout and this (and using Google Fonts) makes that possible. Unfortunately I have an issue the developer can't reproduce and therefore can't fix. He is not very communicative about helping me and doesn't seem interested. So every update I have to make a change to his content.js file. Otherwise, this extension is fantastic!

It's a great useful plugin for markup! I improve my markup skills because I can do my work with high accuracy. I compared markup and design by Screenshots and Photoshop before. But 4 years ago I had known about PerfectPixel plugin and its saved me a lot of time. By that plugin, I added a new design and see differences instantly! I definitely recommended using PerfectPixel the plugin to markup design.
