Hello.

In environments with old versions of VMware vSphere there is no other option than to use a old browser that supports Adobe Flash.

Personally I use the following combination, but only to manage VMware vSphere, to surf the internet I use a more current browser.

Firefox ESR 38.8 (32bits)

Adobe Flash 29.0.0.113

Both the browser and the flash player must be configured so that they are never updated
