A "Quantum" is so TINY, photons push it around, randomly.

Mozilla remotely disabled my Firefox 56 (2017) extensions !
So I'm customizing the latest version of Firefox, "Quantum"
( a "Quantum" is so TINY, photons push it around, randomly ).

When my hacks go wrong, because Quantum doesn't want "hackers" (people)
tampering with their precious product ( blocking their ad revenue ),
I use either "-safe-mode" ( the command line switch ) or Google Chrome.

Getting everything to open in a new tab is VERY difficult;
" Tab Mix Plus " doesn't work anymore, thanks to TINY Quantum;
so I'm using the (flaky) "Open In New Tab" extension on
" *YouTube.COM " and " *Google.COM ".

While I enjoy "hacking", it's time consuming, and I sometimes give up;
if you have less experience than me, as most do, you'll give up sooner.

Using my custom console, "X.EXE", I run:

/__/EXEs/YouTube-DL --embed-subs --write-auto-sub --no-playlist
--buffer-size 222k -f "bestvideo[height<=720]+bestaudio/best"
-o "../MKV/-- YouTube Recent/%(title)s -- %(id)s .%(ext)s"
YouTube.COM/watch?v=diPrOl4QZ_E

" YouTube-DL ", which works on hundreds of sites, outputs:
