Reproducible on: Firefox 38.0.5b1-build1 (20150510205200) Affected platforms: Windows 7 (x64), Windows 8.1 (x86), Mac OS X 10.9.5, Ubuntu 14.04 (x64) Steps to reproduce: 1. Launch Firefox. 2. Open a Reader View-compatible page, e.g. http://www.bbc.com/news/world-europe-32685942 or http://bits.blogs.nytimes.com/2015/03/30/the-path-toward-tomorrows-internet/?_r=0 3. Check the Browser Console. Expected result: * The example pages can be successfully displayed in Reader View. * There are no error messages thrown for this action. Actual result: * The example pages can be successfully displayed in Reader View. * The following error message is thrown by ReaderParent.jsm:95:12 in the Browser Console: > ReferenceError: CustomizableUI is not defined Additional notes: * Nightly is NOT affected, as of 40.0a1 (2015-05-10). * Aurora is NOT affected, as of 39.0a2 (2015-05-10). * This issue might be a regression, I'll follow up with a regression range as soon as possible.
This sounds like bug 1158960, which was just uplifted.
This rebased mozilla-release landing: https://hg.mozilla.org/releases/mozilla-release/rev/3e9805c11aa3 missed the CustomizableUI getter addition that in Nightly is blamed on the patch for bug 1155523 ( http://hg.mozilla.org/mozilla-central/annotate/d264b461947f/browser/modules/ReaderParent.jsm#l16 ), which is therefore now not present on either beta or release. I'm assuming we're overwriting beta with aurora later today? In which case, we just need to add that line on mozilla-release.
Thanks for catching that Margaret and Gijs for the investigation. I checked mozilla-aurora and the line isn't missing there. I'm not sure how it got there but not on mozilla-release. Must have just been a mistake in a merge conflict.

Looking at this more, without this fixed users won't be able to add the current reader view page to Pocket from within reader view.
