README: Revise some "issues inherited from Mull" + related things

By replacing RFP with (hardened) FPP as described in https://gitlab.com/ironfox-oss/IronFox/-/issues/20 (commit https://gitlab.com/celenity/Phoenix/-/commit/fa1a52aba4229fb8bad5132b8939037c314021ae), two "Issues inherited from Mull that still apply to IronFox" mentioned in the README become obsolete and can be removed/crossed out:

  • Dark mode for websites is disabled due to resist fingerprinting. Please do not disable RFP.
  • Multitouch gestures will not work due to resist fingerprinting. Please do not disable RFP.

In fact, both work well in the recent IronFox. The first entry somehow still applies, since "The browser's default theme is now set to light mode for added fingerprinting protection" as mentioned in IronFox!3 (merged) / the release notes, but it could be added to "Issues originating in IronFox" or a separate category (see my comment below) as:

  • Browser's default theme (and hence webpages' color scheme) is set to light mode for added fingerprinting protection, but it can be changed in Settings > Customize > Theme (see release notes v134.0.2, and issue IronFox#20)

[Edit]: perhaps this entry is not even necessary, if you link to https://codeberg.org/celenity/Phoenix/wiki/Features#fingerprinting, where this is already mentioned.

Besides, I never understood the entry:

  • Dark Reader is known to be incompatible with IronFox's changes and will cause significant breakage/slowdowns.

Dark Reader always worked well for me both in Mull and IronFox. If you confirm, you can drop also this entry.

Another thing regarding the list of (solved) issues in the README:
Behind each element, you could also add the related PR/issue/release link to provide some context.

Another thing:
Your description of new changes or features in the release notes is very rich and informative. Perhaps you could consider adding those also to the README in a separate category as collapsed list, documenting how IronFox differs from upstream Firefox more prominently. The list will be long, but very informative.

[Edit]: Those related to Phoenix are already well-documented in https://codeberg.org/celenity/Phoenix/wiki/Features (which also should be linked there) and don't need to be repeated; all remaining things could end up in IronFox's README.

Last thing:
Big thanks for creating and maintaining IronFox and related projects! ❤️
