      Description

      NOTE: This bug report is for Confluence Cloud. Using Confluence Server? See the corresponding bug report.

      Summary

      The WebDAV Launcher Office Connector is not signed correctly and so does not install or run in Firefox 43.0 or greater. This is a recent change in Mozilla policy for extension signing.

      Environment

      • Firefox 43.0 or higher
      • WebDAV Launcher 1.0.8.1-signed
      • Windows, Linux or Mac

      Steps to Reproduce

      In Firefox

      1. Go to Help > About Firefox
      2. Make sure Firefox is version 43.0 or higher
      3. Uninstall the WebDav Launcher

      In Confluence

      1. Go to a page with a Word document as an attachment
      2. Click on the Word document
      3. Click ... > Edit in Office
      4. Click Ok for the Download box
      5. Click Allow

      See error

      Expected Results

      The document should load in Word

      Actual Results

      The Firefox add-on is not added. If it is already added, it will not work. The Add-on shows

      The add-on downloaded from this site could not be installed because it appears to be corrupt.
      

      The WebDAV launcher is disabled with the message

      WebDAV Launcher could not be verified for use in Firefox and has been disabled.
      

      Notes

      This is a change in Firefox with Add-ons that are not signed correctly.

      Workaround 1

      1. Download the plugin directly from mozilla (using Chrome so it doesn't auto install) https://addons.mozilla.org/firefox/downloads/file/259818/webdav_launcher-1.0.8-fx.xpi
      2. Go to about:addons, then Cog Menu > Install Add-On from file and select the .xpi file
      3. Click Install on the pop-up box, then Restart

      Workaround 2

      1. Go the location bar and enter about:config
      2. Click I'll be careful, I promise!
      3. In the new Search field at the top enter xpinstall.signatures.required
      4. Double click the entry to make it false

      You can also put this entry in user.js in the firefox profile directory

      user.js
      user_pref("xpinstall.signatures.required", false);
      

      The plugin will now work.
