Webdav Launcher in update.atlassian.com is outdated, and does not support Firefox 5 and above

Issue

When a user tries to open a Word file through the Office Connector (using Firefox), he/she gets prompted to download the Firefox WebDAV Launcher Add-on; If the user is using Firefox 5 and above, he/she will get the following error message, upon download attempt:
"WebDAV Launcher could not be installed because it is not compatible with Firefox 5.0."

Cause

Webdav Launcher in update.atlassian.com is outdated, and does not support Firefox 5, but the Webdav Launcher in https://addons.mozilla.org/firefox/downloads/file/119556/webdav_launcher-1.0.5-fx.xpi supports Firefox 5 and 6.

Proposed Solution

https://update.atlassian.com/office-connector/URLLauncher/latest/webdavloader.xpi should be in sync with the latest version available in https://addons.mozilla.org/en-US/firefox/addon/webdav-launcher/

Workaround 1:

Manually download the WebDav Launcher from https://addons.mozilla.org/firefox/downloads/file/119556/webdav_launcher-1.0.5-fx.xpi

Workaround 2 (This will change the URL that Confluence will trigger the user's browser to point to, to download the Webdav Launcher addon - changing it from update.atlassian.com, to the one in addons.mozilla.org):

1. Shutdown Confluence
2. Go to <ConfluenceInstallation>\confluence\WEB-INF\classes\com\atlassian\confluence\setup
3. Open atlassian-bundled-plugins.zip using WINRAR
4. Navigate (from within WINRAR) to OfficeConnector-1.15.jar\templates\extra\editinword
5. Open up editInOffice.js using your text editor (You must double click on the file, and not drag drop it to your text editor. If it does not open up, you need to set the file association for .js to your text editor, and try to repeat from Step 3 again).
6. Search for update.atlassian.com, you should find a line that looks like the following:

   InstallTrigger.install({'WebDAV Launcher': 'https://update.atlassian.com/office-connector/URLLauncher/latest/webdavloader.xpi'});
   

7. Change the URL to 'https://addons.mozilla.org/firefox/downloads/file/119556/webdav_launcher-1.0.5-fx.xpi'
8. Save the textEditor (WINRAR should prompt whether you would like to update the archive, click Yes, you should be prompted to update the archive twice, in OfficeConnector.jar, and atlassian-bundled-plugins.zip. If you are not prompted to update, this could be because editInOffice.js was not opened through double click as described in Step 5)
9. Go to ConfluenceHomeDirectory, and remove the following folders (they will be rebuilt on Confluence startup):
   • bundled-plugins
   • bundled-plugins_language
   • plugin-cache
   • plugins-osgi-cache
   • plugins-temp
10. Startup Confluence
