What is the Firefox Gecko equivalent to Chrome's --disable-dev-shm-usage flag
Try to use a volume in the docker run execution with the flag -v /dev/shm:/dev/shm
This should work for chrome and firefox execution without any flag in the capabilities
After looking into the documentation (https://developer.mozilla.org/en-US/docs/Mozilla/Command_Line_Options#How_to_use_command_options), there is no such flag for Firefox.
