Sure!

Do you have a local build of Firefox already? If not, you can find instructions [here](https://firefox-source-docs.mozilla.org/setup/index.html).

As discussed in comment 4, we are initially only looking to change the value of the [apz.gtk.pangesture.delta_mode](https://searchfox.org/mozilla-central/rev/0b55b868c17835942d40ca3fedfca8057481207b/modules/libpref/init/StaticPrefList.yaml#593) pref, to 2 (pixel mode), and only on the Nightly branch. You can see an example of making a pref value conditional on Nightly [here](https://searchfox.org/mozilla-central/rev/0b55b868c17835942d40ca3fedfca8057481207b/modules/libpref/init/StaticPrefList.yaml#4539-4543).
