Web Developer Tools are a great set of options for those developing web sites with a Inspector, Web Console, Debugger, Style Editor and more. Pale Moon supports the W3C Media Source Extensions and playback for MP4 and WebM video can be toggled. Furthermore, several options are available from the Preferences to set different levels of security by blocking addons, password management (protected by a master password), HSTS, HPKP and an optional do not track setting. With support for themes and layout customization, it's quite possible to have the browser looking the way you want it. From what we've seen, it adheres to web standards without a hitch. Though Pale Moon used to be heavily based on Mozilla's Firefox, it has since come a long way by developing its in house Goanna layout engine. It is optimized for usage on modern processors which includes a number of enhancements over the traditional set of browsers many are used to.

Pale Moon is a free and open web browser on the layout and rendering engine Goanna. Fast, stable and free web browser with addons, customizations and a developer tools with a familiar user-interface.
