 We currently use [a fork of Puppeteer] with a small number of tweaks
 and workaround to make them run against Firefox.  These changes
 will be upstreamed to Puppeteer when we feel more comfortable about
 compatibility with Chrome.
 
 To update the vendored copy of Puppeteer under _remote/test/puppeteer/_:
 
-	% ./mach vendor puppeteer
-	 0:00.40 Removing old checkout from remote/test/puppeteer
-	 0:00.56 Checking out firefox from https://github.com/andreastt/puppeteer.git to remote/test/puppeteer
-	 0:03.35 Removing unnecessary files
-	 0:03.35 Updating remote/test/puppeteer/moz.yaml
-	 0:03.35 Registering changes with version control
-	 0:03.73 Updated Puppeteer to firefox
+	% ./mach remote vendor-puppeteer
 
 This will replace the current checkout with a fresh copy from
 the predefined remote, which currently is the `firefox` branch on
 https://github.com/andreastt/puppeteer.git.  You can override which
-remote and commit to use with the `--remote` and `--committish` flags:
-
-	  -c COMMITISH, --commitish COMMITISH
-	                        Repository tag or commit to update to.
-	  --remote REMOTE       Remote git repository.
-	  --ignore-modified     Ignore modified files in current checkout.
