Created attachment 8750772 [details] Cannot_Select_or_Copy_text_in_debugger_popup.png User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:48.0) Gecko/20100101 Firefox/48.0 Build ID: 20160508004021 Steps to reproduce: Hover over String variable in Devtools Debugger, then try to select the text. Actual results: Text is not selectable and cannot be copied. See screenshot Expected results: Make the text selectable so that it can be copied using Ctrl+C. I needed this a few times where I wanted to paste the value (String) of a variable to a fellow developer, but it was not possible. I had to retype the whole String by myself by hand.
