 In "safest" security level `svg.disabled` is set to `true` in Tor Browser.
 This causes the UI icons in the latest versions of uBblock Origin and
 uMatrix to disappear.

 The author of the extensions declined working on this with a note:

 "I consider this a browser issue, to be reported to Firefox issue tracker.
 Extensions extend a browser abilities, they should not be subjected to
 restrictions which are meant to be imposed on web pages."

 However as this is Tor Browser specific, I am reporting it here.
