Sure. When you navigate to the "about:config" URL, you will be presented with an interface for changing Firefox preferences that aren't otherwise accessible. The one you need to change is `gfx.webrender.all`, and you need to set it to `true`. So the steps are:
1) Navigate to "about:config".
2) In the field at top where it says "Search preference name", type "gfx.webrender.all".
3) In the row where "gfx.webrender.all" appears, there will be a button on the right-hand side with two arrows. Click that button and confirm that the test in the middle of the row now reads "true".
4) Restart your browser.

That should force your browser to use the hardware video path, which will reduce your CPU usage for your use case. It may also cause visual problems for some web content, which is why your driver is on our blocklist. You also should update your driver if possible which will in general give you a better experience with visuals in Firefox.
