Well, Youtube is finding a way around Enhancer now as well. I got it installed, and it worked for a few days, but I’m getting that popup again. Have you had any problems as of late?
Nope. I also use uBlock Origin adblocker and for really pesky websites, YesScript2 javascript blocker
uBlock is available for all browsers - https://github.com/gorhill/uBlock#ublock-origin
YesScript2 is firefox only - https://github.com/log69/yesscript2
I use Waterfox, a privacy based version of Firefox
