Shockwave download fails

[CaptainMurica]

When starting Firefox after enabling Shockwave, the plugin installer fails to download, likely due to the issue described in the FAQ section. I am using Arch Linux.

Here is the output of list-enabled-all:

silverlight5.1
unity3d
shockwave

Here is the terminal output when I launch Firefox with Shockwave enabled:

There is an invalid checksum in install-dependency script. Again.

Use "sudo pipelight-plugin --update" to get the new checksums.
