True for my laptop and desktop for Firefox, but not Chrome. Some sites won't give access to ad-blocking browsers and I find it a hassle to unblock. Easier to just copy the URL, open a Chrome window, and paste it there.
You much prefer subtitles to dubbing in foreign language movies because the dubbed speech is almost always horribly stilted.
Sort of true. I think they have improved the dubbed acting very much, compared to what it used to be. But I use CC most of the time, so I'm used to reading the words and usually use that.
