Why are there many hundred Chromium based browsers, but seemingly very few Firefox based browsers? - The Lemmy Club

Have you tried looking for โ€œMozillaโ€ based browsers? Because thatโ€™s the engine or whatever Firefox uses and there are many of them.
Iโ€™m pretty sure geckodriver is the browser engine for Firefox, not Mozilla. I think Mozilla is the company that maintains Firefox, along with other projects.

They have forgotten the sacred scriptures!

โ€œAnd so at last the beast fell and the unbelievers rejoiced. But all was not lost, for from the ash rose a great bird. The bird gazed down upon the unbelievers and cast fire and thunder upon them. For the beast had been reborn with its strength renewed, and the followers of Mammon cowered in horror.โ€

from The Book of Mozilla, 7:15
