Found as part of bug 1302570. I think the problem has been introduced in bug 1230638 but I'm not sure. Interestingly my test gives different output for Windows and non-Windows here. On Windows I have: missing chrome://pocket/skin/toolbar-lunaSilver.png referenced from chrome://pocket/skin/pocket.css On Linux I have: missing chrome://pocket/skin/toolbar-lunaSilver.png referenced from jar:file:///builds/slave/test/build/application/firefox/browser/features/firefox@getpocket.com.xpi!/chrome/skin/windows/pocket.css On Mac I have: missing chrome://pocket/skin/toolbar-lunaSilver.png referenced from jar:file:///builds/slave/test/build/application/Nightly.app/Contents/Resources/browser/features/firefox@getpocket.com.xpi!/chrome/skin/windows/pocket.css I've finally understood that the error on Windows is because the file is packaged with an uppercase t (*T*oolbar) but used in the CSS file with a lowercase t (*t*oolbar). The Linux/Mac errors are because chrome://pocket/skin/ doesn't point to windows/ folder there, so we can silence the error by using a relative path.

I created https://github.com/mozilla-partners/pocket/pull/5 . Shane, can you review/merge? How does this reach central?

Comment on attachment 8791227 [details] [diff] [review] Fix m-c isn't the canonical repo for pocket, but figurative r+ because I just wrote the same patch - though I added a semicolon.
