Ubuntu 12.04 and Firefox 23 - how to turn off JavaScript?

Question

My browser updated yesterday and today I've noticed that the option to turn off JavaScript is no longer there. Did they relocate it somewhere? Help.

Solution

The option was intentionally removed in Firefox 23, on the logic that blocking all javascript makes a significant fraction of sites unusable, and so blocking all javascript, everywhere, is seldom desirable behaviour. As the bug report linked by edwin notes, this was a controversial change.

You can blanket disable javascript by going to page about:config and setting the key javascript.enabled to false.

However, if you want to block javascript an extension like NoScript which gives you fine grained control over which scripts run is a better choice.
