Ancestry Utils is a Greasemonkey script that customizes the way Ancestry.com, particularly Member Trees, display and behave. This script requires Firefox with the Greasemonkey add-on. I understand that Chrome and Safari offer some support for scripts like this, but I believe I've made use of features only available in Firefox.
To install:
- Install Firefox and/or Greasemonkey
- Come back here, using Firefox, and click the download button in the menu on the left
- Follow the Greasemonkey prompts
