What is application virtualization software?

Question

Network administration

Good afternoon!
Need to virtualize several applications (firefox and thunderbird). It is necessary that they open as in Citrix (only their own window).
Please tell me if there are more or less cheap analogues?
I liked Ulteo, but the developers do not respond to the price request (I wrote in via the form on the site\in the facebook group\in the forum).

Answer 1

Is Docker not good for you? I don’t quite understand what specific use-case you have.

Answer 2

Like Ulteo, get the Community Edition
