Ranorex extension not appearing in Firefox Addins page

[JimLin]

Hi,
I'm running Ranorex version 7.2.1.

I am having problems installing the Ranorex extension in Firefox. The wizard says that it's installed it successfully, but it doesn't and the extension doesn't appear in the list of extensions/plugins in FF. I have tried doing it with FF running as admin and restarting it after the supposed install, but nothing has solved it. I have searched for the Ranorex extension in the main FF addins page, but it doesn't appear there. Does anyone have any ideas, what the problem is?

Regards,
James

Hi, sorry, I was being stupid, I had thought we were well above FF 50, but it turns out I was on 47. The Ranorex extension installed and activated perfectly after I upgraded FF.
