SafariZoom

This application changes the behavior of standard "zoom" button in the Safari web browser. Default behavior of this button is to modify window dimensions basing on the size of content page.

It can be useful for some applications like "Finder" or "Pages", but many people consider such behavior to be annoying when applied to "Safari". Most often you click this button to see the whole page content and the best representation in this case is screen-wide window size, like in FireFox. After SafariZoom installation, Safari would maximize its window size on "zoom" button click. Second click on "zoom" button will cause window to restore its previous size.
You can disable or uninstall this add-on any time your wish from Safari Preferences window.
