Is there a light weight selenium web driver for linux?

I had this question, found a privated reddit post, so I figured I'd ask again :)

I'm basically trying to figure out a minimal container that can load pages via selenium and take a screenshot.

"I am presently using a firefox gecko driver with python in ubuntu for my auto testing. The problem is it uses a very high memory about 150-350 mb and also cpu for a single site. Is there any lightweight selenium web drivers which uses less system resources? Can you recommend any? "
