Chrome: Google's web browser supports a huge library of extensions, but digging through menus to disable them when you need to is a pain. SimpleExtManager simplifies managing your add-ons.
Click on the SimpleExtManager button in your tool bar and you'll see a list of all your extensions. You can disable them with a check box, or use the shortcuts to quickly jump to settings or uninstall the ones you don't need anymore. The add-on also lets you group extensions together if you have a few you know you'll always want to keep and others that you only need sometimes.
