I recently did a new install of FF. I was originally on 51.0.1 x86 and decided to go with 59.0.1 x64. Youtube playback of videos is as per norm, nothing changed. However the IDM drop-down no longer shows MP4, only MKV. I use IDM to get ethnic videos for my Mum to watch on the TV in lounge room. Had no issue before with sourcing these videos in MP4 via IDM, but now it just doesn't wanna' work. I have asked for assistance from IDM support. They gave me some tips, but no dice. 1 - Update IDM 2 - Use the idmmzcc3.xpi extension 3 - Tick "Use advanced browser integration" I thought I'd ask on here if anyone has noticed the disappearance of MP4 (I have seen MP4 in "some", but before it was in "all") in IDM drop-down on latest FF (I think). Here are some of the links that I have seen in MP4 before this week... watch?v=wo9pvAUGF7U watch?v=Fzk3f_McOC0 watch?v=LDfmn3w1-TY Thanks for any replies...
