can not access vcenter server since upgrade to firefox 55

Posted

After updating to firefox 55 I can no longer access VMware vCenter web UI. Note. vCenter uses flash. I have a flash plugin installed and I can access other flash sites ok.

I get the following error when trying to login.

"Connection Error Could not connect to vSphere Web Client. Contact your administrator to fix this issue."

If I try the same from chrome I can login without issue. Also downgrading to firefox 54 allows me to login.
