There are two settings, and the MDN page that you linked to says there's a single default setting for each setting.

Quoting the page's notes on these default values:
> **Use hardware acceleration when available**: [...] This box is checked by default but the feature isn't available for all graphics processors. 
> **Content process limit: [...]  The default is eight. Having more content processes can improve performance when using multiple tabs but it will also use more memory. You can reduce the number of content processes if your computer is running out of memory.

(Note that we're actually changing the content-process behavior soon, in an effort we're calling "fission"; you can read https://hacks.mozilla.org/2021/05/introducing-firefox-new-site-isolation-security-architecture/ for more on that.)

Hopefully this answers your questions. I'm going to close this bug as INVALID since it doesn't sound like there are any issues with Firefox itself (no bugs or code changes needed here).
