I also browse with disabled JS by default, enabling it on selected sites for selected JS sources. It has several advantages:
1) Web is much faster.
2) Often JS makes continuous CPU load, raising speed of CPU fan to noisy levels.
3) Sometimes JS is used for animations, i hate animations on web pages.
4) Sometimes JS is used to auto-play videos (although recent Firefox with proper settings ca block that even with JS enabled in most cases), i hate auto-play videos. That was my primary reason to switch to disabled JS in the past.
5) Often cookie and other pop-ups are implemented with JS and do not show when JS is disabled (while the web still works).
