Yeah, a script that removes parameters would conflict with a script that adds parameters.
Having a look at the script, it adds the '&gl=ca' parameter. What this does is set geographic location to canada, so it downloads videos from servers in canada.
If you want to keep the gl parameter, you can change:
var youtubeParams = /&(feature|src_vid|annotation_id|[gh]l)=[^&#]*/g;
to
var youtubeParams = /&(feature|src_vid|annotation_id|hl)=[^&#]*/g;
I wouldn't have thought it would remove all and every parameter, just unnecessary ones.
Anyways, that fixed it. Thanks!
Interferes with the "Youtube Auto Quick Buffer" script
Interferes with this script: https://greasyfork.org/en/scripts/7924-youtube-auto-quick-buffer, because of the params it adds to the URL which makes the page refresh over and over again nonstop.
