User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:40.0) Gecko/20100101 Firefox/40.0 Build ID: 20150410030204 Steps to reproduce: Not quite sure this bug only affects this Janus Proxy add-on or there maybe others as well. 1. Go to https://github.com/mozilla/janus-addon/blob/master/janus.xpi and View Raw to grab the add-on 2. Once installed, the Janus add-on icon is HUGE in Speed Dial. Actual results: Janus Proxy add-on icon is HUGE in Speed Dial compared to the rest of stock feature Firefox icon and some other add-ons Expected results: Same size with other icons in Speed Dial Note: Since this Janus project is halted, should this be Janus problem or Firefox handling problem? Before I updated my Firefox, the icon was still in normal size...
