SpellBook

Bookmarklets, unlike extensions, can be used on mobile browsers and they are more secure as they cannot modify web pages in the background or insert ads automatically.

SpellBook collects your bookmarklets scattered in the Bookmarks folder, places them all in a special Bookmarklets folder and you can then execute any bookmarklet from the right-click menu.

The bookmarklets menu is auto-updated as you add or delete bookmarklets in the browser.
