This issue has been closed (https://support.mozilla.org/en-US/questions/1283359) but it's still not working in 2022.
Font size in Firefox is not obeying the font size specified in a page, despite "Allow pages to choose their own fonts, instead of your selections above" being set in the settings.
For instance open https://www.w3schools.com/cssref/pr_font_font-size.asp in Chrome and Firefox. You'll see that the font-size of "Example" might be claimed to be 24px in the inspector, but it's clearly smaller than in Chrome.
This is a bug with Firefox.

It is possible that your Firefox uses another font that is smaller than what Google Chrome uses. Did you check this as well ?
This might also be a problem with the Windows DPI setting and the default zoom setting in Firefox.
