Iceraven has had this capability forever, no big announcement required.
If you want to use Firefox on android and don't want to deal with these artificial restrictions and excuses for bad behavior just get iceraven and call it a day.
"Note that Iceraven Browser includes some unstable code written by Mozilla, with our own added modifications on top, all shipped with the stable version of GeckoView engine."
I wouldn't use iceraven if security was a priority.
Fennec on the other hand is much closer to FF , quoting their page :
Iceraven is FF for Android, with tracking and telemetry removed, some redesigned features (ie tiles) and about:config, and mostly an attempt at supporting desktop add-ons which were removed when Fenix/GeckoView came to life in 2019.
Stability and security is not a priority though. Updates are slow.
I use it primarily for compatibility with my favorite add-ons not available on FF Android: I don't care about cookies, Cookie AutoDelete, Translate Web Pages, etc.
Mull is another FF Android fork may be worth taking a look at.
