i am thinking that those get blocked somehow by greasemonkey.
can you help me to install those manually?
besides, i found ninjakit for safari 5 which is excellent!
For GM 4+ click "New user script..." from its menu, then paste the script's content there.
could install finally also on tenfourfox by using the latest tenfourfox (which is based on ff45) and the according version of greasmonkey.
as plugins are only possible until tenfourfox (ttf) 17, i had to use nevertheless that version , and downgrade greasemonkey . fortunately the in the process , the viewtube script did not get deleted. so i am assuming this error is somehow connected to the used greasemonkey for ttf17 which is greasemonkey 1.10+ signed.
would like to add for using plugins on tenfourfox 17, on has to enable them first in about:config then sarch for plugins and toggle to true.
The installation issue was caused by the missing viewtube,png image, I've readded it to fix this.
Would it be possibile to enable download from Dramafever as well?
I think this site uses HLS/M3U8 only. I can get the stream but you'll have to use another tool for downloading, like ffmpeg.
