Affected build: Firefox 40.0a2 Aurora, build ID: 20150529004007, Dutch Affected platforms: Windows 7 32-bit, others unknown STR: 1. Open Firefox using a clean profile; 2. Open a newtab page; 3. Observe the newtab page tour. Results: Text for the "Continue tour" button on page 1 of 3 is cut-off on the right (lacking 2 characters.) Considering string lengths for other locales *, it would be nice to have some wider buttons for both options ("Skip this" is the other one) or make their widths adapt automatically depending on their string lengths. * https://transvision.mozfr.org/string/?entity=browser/chrome/browser/newTab.properties:newtab.intro.continue&repo=aurora
