Instead of building firefox using `//browser_patches/buid.sh ff-beta`,
one can use `//browser_patches/repack-juggler.mjs ff-beta`.
The script will download the last Playwright build, and repack
Juggler and preferences there.
With this change, the script is now 2-stage:
- first, prepare browser build with `repack-juggler.js --prepare`
- afterwards, run the script to repack tot juggler version with the
bubild
This patch adds a new script -
`//browser_patches/firefox/repack-juggler.mjs`
This script lets you test Firefox changes if they are Juggler-specific
without firefox checkout / compilation.
The `repack-juggler.mjs` script does the following:
- downloads the latest build of Firefox-with-juggler
- finds an `omni.ja` file with Juggler files inside
- replaces juggler in omni.ja with the current juggler files in the index
