On ac, we don't manage cookies when downloading, GeckoView owns the cookies. I'm not sure how it manages cookies internally :owlish could help us to clarify. What I'm aware of it's that we are not indicating to the `GeckoWebExecutor` (the piece that does the download) that we are on a private mode. I can see a flag [FETCH_FLAGS_PRIVATE](https://searchfox.org/mozilla-central/source/mobile/android/geckoview/src/main/java/org/mozilla/geckoview/GeckoWebExecutor.java#97) but it's package private. Another thing is that we are on the middle of moving away from this api see [AC #8312](https://github.com/mozilla-mobile/android-components/issues/8312). I'm not aware either how cookies are manage with this new api.
