Probably. Same processes when you run Firefox. With Firefox if you run command pstree you can see all the Isolated Web Co processes are child processes of GeckoMain process (and Gecko is the web engine of Firefox).

It looks like this with the 'pstree':

Code: Select all

├─lightdm─┬─Xorg───9*[{Xorg}]
│         ├─lightdm─┬─cinnamon-sessio─┬─GeckoMain─┬─Isolated Web Co───26*[{Isolated Web Co}]

it comes from firefox

Hm, from Waterfox I would say, considering that the OP uses Waterfox .
