That pausing glitch also happens for me, but only on the Classic version. I think it may be because Minecraft automatically pauses when it loses focus, so somehow clicking while in a browser causes it to lose focus. I've tried the normal version outside of a browser, though, and the glitch completely went away.

I'd recommend the PC version. I haven't played the Xbox version, but the PC version has a ton of content (not even counting all the mods out there). I personally think vanilla Minecraft sometimes gets a bit too bland, even though the PC version has a lot of content, and I like to play with mods. But you might have a different experience.
