User Agent: Mozilla/5.0 (Windows NT 6.3; rv:41.0) Gecko/20100101 Firefox/41.0 Build ID: 20150627030211 Steps to reproduce: 1) Open "about:addons" on Nightly 41.0a1 2) Confirm the version number in addon-list Actual results: The version number was removed in Add-ons Manager from Nightly 41.0a1 Expected results: The version number should not be removed. because... - Have the responsibility to provide accurate and easily viewable information about add-ons, plugins and services. - Properly address vulnerability created by older version. (e.g. Adobe Flash) The version number is NOT UI clutter. It's a issue of UI design. My suggestion are... - Keep version number element in Addons-Manager. - Complete Theme Developer decide the version number visibility and UI design by css. I strongly request a review of this change. Thank you in advance.
