How to run multiple Selenium Firefox browsers concurrently?

Trying to run multiple processes concurrently on the same machine, which use Selenium. What would happen is something like this:

python my_selenium_process1.py &
python my_selenium_process2.py &
python my_selenium_process3.py &

As far as I have been able to test, this results in Selenium opening the Firefox instances in sequence, which is not the desired behavior.

Additional note: According to this question on superuser about multiple Firefox instances, the way to do this would be to use the --no-remote start up flag for Firefox. This seems like a good way to go, but I'm not sure if there is a simpler way to do it or if this is even what I'm looking for.

Edit: The purpose, more than speeding up a particular test case, is to allow multiple Selenium processes to run concurrently.

Thanks very much! Any suggestion will be appreciated!

Have you considered implementing a selenium grid?

Selenium Grid will help you scale by running tests in parallel. Just setup a hub and node with the following commands:

For the hub

java -jar selenium-server-standalone-2.30.0.jar -role hub

and for the node

java -jar selenium-server-standalone-2.30.0.jar -role node  -hub http://localhost:4444/grid/register
