How To Enable & Manage Extensions In Safari 5



With the release of Safari 5, Apple introduced a much-requested feature — extensions.

Extensions are a better way to add those little missing features than the old and complex plug-in approach. Extensions have been available on Firefox and Chrome for a while and finally are available for Safari too.

However, Apple currently labels it as a developer feature, which needs to be enabled before extensions are available.
