You can use Extension Manager to manage extensions developed for Dreamweaver, Flash Professional, Photoshop, InDesign, InCopy, Illustrator, Adobe Premiere Pro, and Prelude. Make sure your version of Extension Manager matches the version of the products you are extending. For example, use Extension Manager CC to manage extensions in Photoshop CC. To manage extensions in earlier versions of the products, use the version of Extension Manager installed with those products.

Launch the Extension Manager

  1. Launch the Extension Manager from the Start menu in Windows or the Applications folder in Mac OS.

    You can also launch the Extension Manager from Dreamweaver, Flash, or InDesign, etc. by selecting Help > Manage Extensions.

Manage installed extensions

In the Extension Manager, do any of the following:

  • Sort installed extensions by clicking a column heading such as Name, Version, or Author.

  • Enable or disable an extension by selecting the Enabled checkbox next to the extension.

    Note:  If you installed large numbers of extensions, you can selectively enable and disable them to help manage the performance of the application.

  • Remove an extension by selecting an application from the Products list, and then selecting the extension and clicking the Remove button. Removing an extension uninstalls it from the application.

    Note:  Do not manually remove disabled extensions from the Disabled folder. If you do, necessary changes to your configuration files are not completed.

Manage extension sets (CS6 only)

Extension sets let you manage extensions as a collection rather than individually. Different extensions can be enabled or disabled in a set, and the same extension can belong to many sets. You can rapidly enable and disable multiple extensions by simply switching sets.

  • To configure extension sets, select Tools > Manage Sets, then create, rename, or delete an extension set.
  • To switch extension sets, select a different set from the pop-up menu on the upper right.

You can also export an extension set as an XML file and then import it on another computer.

  • To export a set, click the Export button and select one or more sets to export.
  • To import a set, click the Import button and select the XML file.

Obtain information about an extension

  1. Select an installed extension listed in the Extension Manager and review the information in the bottom portion of the workspace. The information appears in the following tabs.


Describes the extension and where to find it in your product. Developers provide this information when they create the extension.


Includes signature and dependency information, if any.


Preferences include settings to warn you about extensions and configure whether Extension Manager can access Internet. To access Preferences, choose Tools > Preferences.


Includes an option to display a warning when installing an unsigned ZXP extension. A signed extension includes information about the extension’s publisher. If Extension Manager can determine the extension’s publisher, the extension installs silently and you can view the signature information in the Advanced tab. Otherwise, a warning appears and you can decide to continue to install or cancel the installation.

Access Control

Specify whether Extension Manager is permitted to access Internet. By default this option is set to true. If this option is unchecked, Extension Manager will not be able to use Adobe Exchange to submit extensions, access online help and forum, etc.
