When opening a Microsoft Office file via Edit in Office with the Confluence Office Connector, Firefox throws an Out of Memory Error.



  • Browser: Firefox

Diagnostic Steps

  1. Go to your Firefox Add-ons
  2. Go to the Options in your WebDAV Launcher
  3. In the settings you may not see any configurations, or you may see that the application path is incorrect for the version of Office you are running
    1. Quick reference for Office Versions

      Directory PathOffice Version
      Office11Office 2003
      Office12Office 2007
      Office14Office 2010
      Office15Office 2013
    2. Office 2016 is not currently supported. See  CONF-38024 - Getting issue details... STATUS


The WebDAV plugin configuration does not reflect the correct path to the Office executables. In most cases the add-on will automatically configure itself based on information from the system registry. However, issues can occur after an Office upgrade, or the automatic configuration may not work.


Adjust the Firefox WebDAV Launcher's options to properly reflect the correct version of Office for the file extensions you are opening with the Edit in Office functionality

  1. Go to your Firefox Add-ons
  2. Go to the Options in your WebDAV Launcher
  3. Follow the directions in our Configure the WebDAV Connector article, and ensure the settings are configured properly
