Now sure if this is specific to my system or a general change on YouTube's end, but for Firefox the icons used by the extension to perform clicks on have changed to a div elements with a webkit-mask property which contains a URL to the icon.
For Chromium/Google Chrome the extension works just fine because in those browsers there still is a SVG element present inside the new div container.
This breaks the extension completely on Firefox. To fix this the extension needs to check for multiple possible icons.
The above was situation was caused by inproper uMatrix rules.
However, YouTube/Google did update the icons which need to be added in the extension.
In the future issue #16 will allow adding arbitrary icons so users can add support for new or different icons manually while waiting for a permanent fix.
