* '''Release Ubuntu's snap to the main ESR population.''' This can be done by going to https://snapcraft.io/firefox/releases and dragging the candidate version onto the stable channel on the corresponding ESR track. In the case that there are two ESR versions during the extended support period (for example 102 and 115), Canonical would need to create a new branch for the oldest version. The builds will be updated on the new branch by Canonical. When ready to ship, you must use Snapcraft CLI to release this version. Using the example of ESR102 and ESR115, ESR115 would be released to the stable channel on the esr track using the WebUI. After confirming that all builds are built on the custom branch, you would run the following command  snapcraft promote --from-channel=esr/candidate/102 --to-channel=esr/stable/102 firefox : If for any reason this '''cannot''' be done on the WebUI, here are some manual steps. Supposing you have docker installed on your machine, run the following commands:

: $SNAP_REVISION is a number (ex: 370) that can be found at https://dashboard.snapcraft.io/snaps/firefox/, it is not the esr release number. Closing "esr/candidate" will move the users to the "esr/stable" channel. They will get back to "esr/candidate" the day we reopen it.
