If you're having trouble opening downloaded eBooks through Firefox, you'll need to make sure Adobe Digital Editions is the default program for opening ACSM files (which are the download files for eBooks).

If you're having trouble opening downloaded audiobooks through Firefox, you'll need to make sure OverDrive's desktop app is the default program for opening ODM files (which are the download files for audiobooks).

Use the steps below to make Firefox open the download files (ACSM or ODM) with the correct program (Adobe Digital Editions or the OverDrive desktop app).

Windows steps

  1. Open Firefox and click the Menu button near the top-right corner, then click Options.
  2. Click the Applications tab from the left-hand side.
  3. If you're having trouble downloading an eBook, type "Adobe content" (or "ACSM") into the search box and select Adobe Content Server Message (or acsm file).
    If you're having trouble downloading an audiobook, type "OverDrive" (or "ODM") into the search box and select OverDrive Media File (or odm file).
  4. In the drop-down under the "Action" column, select the following programs open each file type:
    • Use Adobe Digital Editions for ACSM (Adobe Content Server Message) files
    • Use OverDrive for Windows for ODM (OverDrive Media) files
    • Or, Always ask (for both)
    Once you've selected the correct program, try downloading a title using Firefox again. If it opens in the correct program, there's no need to continue with these steps.
    If you don't see Adobe Digital Editions or OverDrive for Windows listed, click Use other... and continue to step 5.
  5. In the "Select Helper Application" window, double-click OverDrive for Windows for ODM files or Adobe Digital Editions for ACSM files. Once you've selected the correct program, try downloading a title using Firefox again. If it opens in the correct program, there's no need to continue with these steps.
    If you don't see Adobe Digital Editions or OverDrive for Windows listed, click Browse.... and continue to step 6.
  6. Go to one of the following directories based on your system type and the type of file you're trying to download:
    Note: You can find your system type by searching for System on your computer, then selecting the System option under "Control Panel."
    • eBooks on a 64-bit system: C:\Program Files (x86)\Adobe\Adobe Digital Editions [version number]
    • eBooks on a 32-bit system: C:\Program Files\Adobe\Adobe Digital Editions [version number]
    • Audiobooks on a 64-bit system: C:\Program Files (x86)\OverDrive for Windows
    • Audiobooks on a 32-bit system: C\Program Files\OverDrive for Windows
  7. After browsing to the correct directory, double-click digitaleditions or mediaconsole. Once you've selected the correct program, try downloading a title using Firefox again.
