CherryPy might be a lightweight HTTP server (according to the README), but it uses tons of energy in Firefox. My laptop heats up significantly, fans spin up, battery drains enormously.

Looking at Activity Monitor in MacOS, I see it's specifically "Firefox GPU Helper" that is sucking all the energy.
I have tried disabling hardware acceleration in Firefox, but then the site stutters.

Can anything be done to reduce the energy usage of the web interface?

FYI, this is not an issue in Chrome, but please don't give me reasons to switch back to Chrome 😉
