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
- Go to Help > About Firefox
- Make sure Firefox is version 43.0 or higher
- Uninstall the WebDav Launcher
In Confluence
- Go to a page with a Word document as an attachment
- Click on the Word document
- Click ... > Edit in Office
- Click Ok for the Download box
- 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
- 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
- Go to about:addons, then Cog Menu > Install Add-On from file and select the .xpi file
- Click Install on the pop-up box, then Restart
Workaround 2
- Go the location bar and enter about:config
- Click I'll be careful, I promise!
- In the new Search field at the top enter xpinstall.signatures.required
- Double click the entry to make it false
You can also put this entry in user.js in the firefox profile directory
user_pref("xpinstall.signatures.required", false);
The plugin will now work.

[CONFSERVER-40289] WebDAV Launcher Office Connector is broken in Firefox 43.0
Hi team,
Eagerly awaiting a fix for this as we have 40+ agents who we recently deployed this feature out to, only to have the latest Firefox version break it after only a few weeks of use.
I have been trying to find a way to automatically deploy the user.js file to users profiles on login. The file works and the xpinstall.signatures.required setting is changed to false, however the add-on itself is still disabled in the settings, and there is no way to enable it. So we are completely stuck for now.
Regards.
Hi,
I could verify all of the above steps on my install (5.9.2).
Typical, once I get Let's Encrypt working Mozilla tries to stab me in the back
Regards
Oliver
