Firefox doesn't recognize Webdav Addon

[Matthias Born]

We try to use "Edit in office" from Firebox.

But every time we try to open a document, the webdav addon tries to install again. Again and again.

Has somebody an idea, what the reason can be?

Regards!

Matze

Ps.: It's a confluence 5.9.4 and latest firefox (tried installed and portable allready). Operating system is Win7, it's seems to work in W10...

I find an Issue with a workaround:

https://jira.atlassian.com/browse/CONF-46040

Atlassian. please add this workarounds description to addons.mozilla.org and your own Webdav Addon and "Edit in Office" documentation

I can confirm that! With Firefox version 50 and above, the WebDAV Launcher 1.1.0 no longer works

We have this problem by using notebooks with Win10.
