Running a browser from your VM will allow you to do the same things that you could do with a browser installed in the hosting operating systems.

If you had access to a container that could run from a browser, you could use that as well.

That would be containerisation running on top of $\_\_\_\_\_$ and this concept is entirely possible because a VM in this case is simply an abstraction for a computer $($which could be a server, your laptop, etc.$).$
