I've been looking into this, as far as how I can run selenium browser instances in the background. I found some things about using a virtual GUI instance, or something like that, but it was all for Windows.
I'm using Ubuntu linux so I'm wondering what the easiest way would be to suppress the actual browser instances showing up for the user who started the selenium instances since I am threading like 25 of these, at the moment, and its kind of strange / annoying having all of them open.
Thanks for any advice.
