Installing Plugins

Google Chrome comes with Adobe Flash and a PDF viewer bundled. However, due to redistribution restrictions, Chromium Portable cannot distribute them, but you can install them manually.

First, you need to download the Google Chrome installer matching your Chromium Portable version. Next, open the installer with an archiver like 7-Zip and go to Chrome.7z\Chrome-bin\VERSION, where VERSION is the version you've downloaded. Finally, extract the following files to Data\App (create this directory if needed):

• Adobe Flash Player: the PepperFlash directory
• PDF viewer: PDF.dll and Plugin.vch

Update Mozilla's PDF.js is included in Chromium Portable as of v26.0.1410.5, so Google's PDF viewer is not necessary anymore. You will have to enable PDF.js in chrome://extensions on the first post-update run, though

Warning! Be aware that many plugins are linked to locally installed programs and will not function correctly in a portable environment. When testing plugins be sure to test them on a system that does not have the plugin installed locally.

To install a plugin, first you need to find where it is located in the host computer. Run a local Firefox or Chrome and navigate to about:plugins. In Chrome, click Details on the right. In Firefox, follow these instructions. You should now see each plugin's details, including the file path. Copy this file to Data\Plugins (create the folder if necessary). If the file name does not start with np, then rename it to include this prefix.

You can now open about:plugins in Chromium Portable to verify which plugins are being loaded and used. Again, be sure to test the plugin on a computer without that plugin installed locally!

Additionally, if a system has plugins installed locally for Firefox or Chrome, Chromium Portable should find and use them automatically.
