legacyBackend = true and WindowsJumpLists are not enough any more.

Sure. These are bithack changes for unpacked installation for browsers. Purpose is to make it run on Windows 7, 8, 8.1.

Changing requested DLLs (imports) or changing minimal Windows version (from 10 to Vista (6.0)) could be done with software CFF Explorer.
Changing the same or similar bytes in browser critical files could be done with some Hex editor. I prefer HxD.
Additional DLLs are mostly from Blaukovitch's projects - genius which bithacks newer Chrome, Chromium-based browser and Firefox, too.
Other DLLs are downloaded from dll-files.com site, since it exists in Win 10/11 but not in Win 7/8.

This gist is result of comparing of original:
https://download-installer.cdn.mozilla.net/pub/firefox/releases/135.0/win64/en-GB/Firefox%20Setup%20135.0.exe
and bithacked version from:
https://github.com/Blaukovitch/Mozilla_Firefox_Windows_7/releases/download/Tor4/135.0.0._x64_Firefox7.7z

It helps me to do similar changes to another browser of the same major version to make it works on Win 7.
Example: LibreWolf and Zen browsers can work on my Win 7, too.
