Mozilla FireFox is a web-browser developed and published by Mozilla.

== Vine videos (HTML5 videos) don't play ==
The issue presents itself with a static image appearing instead of a video playing. Vine videos especially have this problem. The problem appears to be at the fault of FireFox's built-in mp4 media player.
'''Solution'''
Disable the built-in mp4 media player:
# Open a new tab
# Type in about:config in the address bar
# If confronted by a page saying "''This might void your warranty!''" click the "''I'll be careful, I promise!''" button
# In the search bar at the top of the page copy and paste ''media.windows-media-foundation.enabled''
# Double-click on the ''media.windows-media-foundation.enabled'' string to disable it
# Restart FireFox and try loading a Vine or HTML5 video
