Preview in Browser doesn't display content correctly in web browser

The updated security settings enforced in the recent Flash Player 23 release impacts Flash content played from the local filesystem, using the web browser. Therefore, to preview the web gallery in the browser, you need to add the location where the web galleries are generated to the list of Trusted Locations in the Flash Player security settings. For more details about this update, see the section Disabling local-with-filesystem access in Flash player by default in Release Notes | Flash Player 23 AIR 23.

Preview in Browser is supported on Internet Explorer, Firefox, and Safari web browsers. 

Workaround

1. Go to the Flash Player Settings Manager:

   1. (Windows) Control Panel > Flash Player

   2. (macOS) System Preferences > Flash Player

2. In the Flash Player Settings Manager dialog, select the Advanced tab.

3. In the Developer Tools section, click Trusted Location Settings.

4. Click Add.

5. Add the following folder location:

   1. (Windows) \Users\[user name]\AppData\Roaming\Adobe\Bridge CC 2017\Adobe Output Module\MediaGallery

   2. (macOS) Users/[user name]/Library/Application Support/Adobe/Bridge CC 2017/Adobe Output Module/MediaGallery

   3. Note: On Mac OS X 10.7 and later, the user Library folder is hidden by default. To make the user library content visible, see Can't see user library files in Mac OS X 10.7 and later.

6. Click Confirm.

7. Once you have added the Media Gallery folder to the Trusted Locations, navigate to the following folder and double-click index.html to preview:

   1. (Windows) \Users\[user name]\AppData\Roaming\Adobe\Bridge CC 2017\Adobe Output Module\MediaGallery\previewInBrowser1\index.html

   2. (macOS) Users/[user name]/Library/Application Support/Adobe/Bridge CC 2017/Adobe Output Module/MediaGallery/previewInBrowser1/index.html
