+### Manual Execution of Smoke Tests
+
+To run the smoke tests manually against an arbitrary version of Firefox **where the installer or (for Linux)
+tarball exists on the web**:

+  labeled "Run workflow"
+- Make sure you are running against `Branch: main`
+- Add the URLs to your installers for Windows and MacOS, and the tarball for Linux in the fields below.

+  - **Windows should be x86, 64-bit (win64), .exe installer (no .msi)**
+  - **MacOS should be a .dmg installer (no .pkg)**
+  - **Linux should be a .tar.xz or .tar.bz2 tarball (no .deb)**
+  - **Version numbers less than 128 are not likely to work**
+- Press the green "Run workflow" option
+- In a few minutes, the top workflow should be yours. Click through to watch progress.
