Essential but feels uncomplete. Rated 3 out of 5 stars

This is an essential plugin but the quality is noticeably lower then other plugins (such as firebug). It still feels Pre-Alpha, although thankfully it wont usually crash your browser. The UI is a bit ugly and limited - it doesn't resize properly with Firebug, If you use it in more then one tab it starts behaving in weird ways, sometimes even requiring a browser restart. For a time the PixelPerfect tab even went blank. Yet I still have to find an equal, free alternative. As I said, this tool is essential, and also popular I guess. It's a bit deceiving and appalling that it's limitations have not been improved yet, and it's been a while.

Thank you for the feedback. Sorry to hear that you're having issues with the plugin.
There are a few things that are not currently supported / have not been properly tested and will be buggy.
1) Only works with one tab
2) Detaching (doesn't work at all)

There is a backlog of improvements (ui, etc), however I am only one person who does this in my free time so updates sometimes take a while. Also if you wouldn't mind filing specific issues on the github page ( that will help me keep track of the outstanding backlog.



Lacking Rated 3 out of 5 stars

I dont know if its my combination of Firefox/Firebug/PixelPerfect, but here, when I refresh the page, the pixel perfect layer comp gets deselected, and I have to select it again to make it visible!
Because of that, if I want to use an overlay, Id rather make myself one as a transparent Div or a faded background image, so that I dont have to keep reactivating it.
Besides, as opposed to other firebug tabs, the Pixel Perfect tab never displays a scrollbar, despite its contents overflowing. Why?
My verdict... hasty implementation for something that could be useful, or at the very least be a cool extension to have.
