If I open the Page Info window and go to the Media tab I can see many links for the assets of a given page, and I can select multiple items. However, I cannot copy these items to clipboard as the "copy" option is greyed out on the context menu as well as the main navbar dropdown. The respective keyboard shortcut ⌘C is also disabled and does nothing. I *can* copy a single link at a time - copy function only stops working when multiple items are selected. I'd simply like to copy that list of links to a text editor. How can this be done and why am not not able to copy these links? Based on my earlier question (which went unanswered and is now archived / https://support.mozilla.org/en-US/questions/1209191 ) I have concluded that this is OS X specific and have since tested on Windows and Ubuntu which are both able to copy multiple links without any problem. I've also filed a bug report here: https://bugzilla.mozilla.org/show_bug.cgi?id=1452537 which has had zero activity or response. I'm not expecting anything overnight but it's been 7 months and would really be nice to at least have an acknowledgement that this problem is real and that someone, somewhere might one day roll out a bugfix.
