FAQ: Error when using the SiteRemote File Manager with Firefox 50
Due to a change in Firefox 50 (see  “In version 50, options must be an object.” in the “Browser compatibility” paragraph here: https://developer.mozilla.org/en-US/docs/Web/API/Document/createElementNS
) it can happen that you get an error when opening the File Manager in your SiteRemote team in Firefox 50 (Error message: Source: undefined / Message: Session.OpenItemAsync).
Although the Mozilla web page announces, that they will change the behavior with Firefox 51 to be compatible again, we adjusted the affected script, so that it works with Firefox 50 again.
This applies to our server at www.siteremote.net and to future releases of the SiteRemote installer.
If you cannot update Firefox or your SiteRemote Server installation for any reason please contact us via e-mail to get the adjusted script file.
