Chrome: If you have a few browser extensions you love to use, but they cause problems on specific web sites or you don't need them enabled all the time, Extension Automation is a simple tool that automates extensions based on the site you're visiting.
With the extension installed, you can set up extensions to only run on specific sites by adding them to a list. This keeps the extensions from slowing down Chrome and clogging up your toolbar. It's also handy if you have a couple extensions you love to use but they cause problems on certain sites.
