jess/firefox: tab crashes due to small /dev/shm

[mviereck]

The recent jess/firefox regulary has tab crashes. This can be reproduced e.g. with youtube videos.

This has been fixed once with https://github.com/jessfraz/dockerfiles/pull/429 that configures browser.tabs.remote.autostart = false. This fix does not help anymore, though.

I found three solutions:

• recommended: --shm-size=4G, found here: https://github.com/D4Delta/firefox-stable
• discouraged: --ipc=host https://github.com/jessfraz/dockerfiles/issues/360
• discouraged: --volume /dev/shm:/dev/shm

Afaik the default size of /dev/shm in Docker containers is 64MB. But firefox needs much more than that.

My previously recommended solution --shm-size=4G does not work anymore.

I am using --tmpfs /dev/shm now.
