Button is Missing in Firefox

I'm running the latest Make GIS Great Again extension in Firefox 59.0.2 on Mac 10.13.4.

I cannot get the View Image button to load at all during Google Image searches. I see reviews for the plugin mention the same issue, but I didn't know if you watched those as much as GitHub issues.

Here's a video of what I'm seeing. https://www.screencast.com/t/Q3RVmh8YvX

Thanks!

Start by reproducing the missing View Image button during a Google Image Search in Firefox 59.0.2 on Mac 10.13.4, using the linked screencast for the expected failure. Trace the extension's Google Image Search integration and confirm that the button loads correctly after the fix.
