I’m seeing some recurrent issues where downloading Firefox ESR from the Mozilla services hangs. After 10 minutes, the build times out and is marked as “errored”.
I am using the following build configuration snippet to install Firefox:
addons: firefox: latest-esr
I am seeing it happen more often when multiple builds are running concurrently. Is it possible that Mozilla is blocking or rate limiting Travis IPs? Should Travis be caching the download instead?
