Can't connect to any site after Firefox change from x64 to x32

[just-me 3]

I have Arcobat DC installed and a long time the Acrobat PlugIn did not work in Firefox. Today somebody told me that the problem is only in the x64 version of Firefox. So I changed to x32 and the PlugIn works but I can't use Edie  If Edie is enabled there is no chance to connect to www.nsaneforums.com etc.

 

Any idea how to fix?

Looks like a wrong configuration in the firewall
