Great idea, well executed, just not convenient for many users. It would be much easier (as many have already said) if the extension was configurable so that users may choose to block nothing until they encounter a problem site (and then block JS if they want).

So I will be uninstalling this and installing Quick JS Switcher instead. Just use the search box to find it.

The hostile comment by anonymous was not a helpful contribution. People can have different ideas to you. It is allowed. :-)
