Question below.
I switched on #Android successfully from Fennec to #IronFox (formerly Mull, https://gitlab.com/ironfox-oss/IronFox), because they now have an option to disable the forced light theme (see screenshot). When they were still called Mull this was not possible to change.
This is exactly the reason whey I have problems switching from #Firefox to @librewolf. The reason for this are my bad eyes and my autism (light sensitivity). So for me (and a lot of others) this is a disability feature (also Darkreader or similar is mandatorily for me). I also think this can't easily be used for fingerprinting, because the amount of people using dark mode on their desktop/laptop is probably very large.
Fortunately #LibreWolf describes how to disable RFP (Resist Fingerprinting) and switch to regular fingerprinting protection (https://librewolf.net/docs/faq/#what-are-the-most-common-downsides-of-rfp-resist-fingerprinting). Although it would be much better if they add a setting like IronFox does.
My question is if disabling RFP and adding those strings to about:config is the best way to have dark mode? Or are there similar forks for desktop (Linux) as IronFox?
