Created attachment 8589043 [details] screenshot from Windows 7 (x64) Reproducible on: Nightly 40.0a1 (2015-04-06), Aurora 39.0a2 (2015-04-06), Beta 38.0b2-build1 (20150406174117) Affected platforms: Windows 7 (x64), Ubuntu 14.04 (x64), Mac OS X 10.9.5 Steps to reproduce: 1. Launch Firefox. 2. Open a Reader View compatible page - (e.g) http://www.bbc.com/news/magazine-32160231 3. Click the "Enter Reader View" button from the Location Bar. 4. Click the "Add page to Reading List" button from the Location Bar. 5. Scroll to the bottom of the page and reduce the width of the window. Expected result: There's a minimum width set, so that the elements from Reader View's UI are not broken by it. Actual result: Reader View's footer is affected by narrow browser windows, as the remove-from-readinglist button is cutoff.
I don't think we should set a minimum width. I'd rather that we have some media queries that change the layout of the page so it works better in small windows. We could make the toolbar horizontal and stick to the bottom of the window, while also decreasing the font-size/line-height.
We no longer have add/delete buttons, nor do we have a footer, so marking as invalid.
