+# Local development workaround for Firefox.
+#
+# Once you build this extension (with `npm install` and `npm run build`, as per <README.md>), to
+# load it, visit Firefox special URL about:debugging#/runtime/this-firefox. Click button "Load
+# Temporary Add-on..." That button shows a file/folder picker.
+#
+# Problem: The file picker does allow you to select `manifest.firefox.json`, BUT it will not load
+# it. It loads `manifest.json` (from the directory where you selected `manifest.firefox.json`)
+# instead. (Indeed, a Firefox defect - but life is too short for us to waste it on Mozilla's
+# bugzilla....)
+#
+# Firefox doesn't allow to use symlinks to workaround the above problem (see
+# https://bugzilla.mozilla.org/show_bug.cgi?id=803999 - symlinks are a security problem).
+#
+# Workaround: This script
+# 1. copies manifest.firefox.json over manifest.json
+# 2. prevents that change from being accidentally committed to GIT.
+
+# Enter the directory where this script is (in case we call it from somewhere else).
+cd "${0%/*}"
+
+# Invoking `/usr/bin/cp` directly, in case there's an alias that warns about overriding existing
+# files.
+/usr/bin/cp manifest.firefox.json manifest.json
