Rated 4 out of 5 stars

I love this extension. All bugs fixed on github https://github.com/janodvarko/PixelPerfect/commit/0f57f6355f68280c37da6b6f6a8331a40d4e4060
Works with latest version of Firefox and Firebug

This review is for a previous version of the add-on (1.8.0.1-signed). 

Another point of view Rated 5 out of 5 stars

For everyone who loves this extension and still wants to use it but leave the last updated firefox as is I have a solution that works for me.

1. search on google for a portable firefox version, prefferably old than actual, for example version 13.0.0 you can try with some newer if you want. This doesn't require install or downgrade your current version of Firefox, just run it and when you are done exit. Is the portable version, you can even take it on your usb stick.
2. install pixel perfect and other extensions that you want
3... done :) happy coding

Yes, I know there can be some changes from an old version to the last version of Firefox... but in the visual part firefox is the same, not big changes, I am right?

Doesn't even work. What a waste of time! Frankly, this pisses me off. It shouldn't even be listed in the directory if it doesn't work.

It's really a long time to wait for the new version.I'm using another tool http://dainiel.github.io/1px/ instead.

Sometimes updates to this plug-in take long to be published, but it's great!

Maybe its time to delete this plugin from firefox if you can't fix some issues?

It doesn't work. Overlays can be selected from the filesystem, but they don't display.

Fix for no "Add Overlay" button in newer versions of Firebug Rated 4 out of 5 stars

I've found a fix posted posted here:
https://github.com/openhouseconcept/PixelPerfect/issues/48#issuecomment-7194152

Seems to have worked fine for me. Good luck! Hopefully some day the developer will update the plugin. I saw new versions of the plugin available on GitHub, but these versions had an entirely different (and much worse, in my opinion) interface and didn't seem to function at all.

Don't work Rated 1 out of 5 stars

Still pretty buggy Rated 3 out of 5 stars

Unusable for me but I'm giving it a three because when it works it's really helpful. Not working in ff 15.0.1, firebug 1.10.3, OSX 10.8.1. On installation, the overlay panel is visible and I successfully added an overlay (which was successfully added to the proper folder in the extension's file tree) but the checkbox to use the overlay is uncheckable. On restart the overlay image (and any added manually through the filesystem) are not listed and the "Add Overlay" button does not appear.

Poor man's pixel perfect from the console (edit the image path as necessary, uses jquery):

markup = '<div class="db"></div>';
$('body').append(markup);
$('.db').css({ 'z-index' : 999, width: '100%', height : '900px', opacity : '.5', background: '#fff url(/gfx/overlay.png) center top no-repeat', position: 'absolute', left: 0, top: 0})

Can't Add Overlays Rated 1 out of 5 stars

The add overlay section of this add-on does not appear for me - and despite searching I'm unable to find a hack that fixes it.

So...pretty much useless unless this very common problem is fixed.

How to add overlay manually Rated 4 out of 5 stars

To add overlay manually:

The 'Add Overlay' doesn't appear in version 1.10 of Firebug. You'll need to roll back to version 1.9.2 to get it working again in this case. Otherwise a pretty useful tool, I have found overlay issues when it comes to working with jquery UI dialog boxes as well as the Pixel Perfect panel not resizing along with the Firebug panel. It would be great if we could get controls to be added to the page overlay rather than having it only tucked into the Pixel Perfect panel

Pixel perfect checker Rated 5 out of 5 stars

I really like this tool because this is the best to check pixel perfect code for my design. I found one of the useful free online tool (http://www.cssprecise.csschopper.com/) to check pixel perfect code for design with great features.

Works great with FF8 with this new version. Very happy.

If it would work when FireBug is in the pop-out mode then it would be a 5/5 plugin
