• When executing docker run for an image that contains a browser please use the flag --shm-size=2g to use the host's shared memory.

The tag structure is as follows:

selenium/standalone-firefox-<Major>.<Minor>.<Patch>-<YYYYMMDD>

Also with browser version and browser driver version

selenium/standalone-firefox-<browserVersion>-<browserDriver>-<browserDriverVersion>-<Major>.<Minor>.<Patch>-<YYYYMMDD>
