Hi all, pdf embedding is not working on mac firefox v66 64bit now while it used to work in the v65. To be 100% clear you can reproduce this issue by visiting https://pdfobject.com/ In the grey frame where there should appear a pdf embed there is white and there are no errors in the console. I am also the one who reported it broken in windows10 v65 32bit https://support.mozilla.org/en-US/questions/1250314 So clearly the bug that caused this is now propagating to other versions. Can someone please investigate?
