Firefox crashing when clicking on its widgets' mic symbol

There is an issue with the widget from Firefox browser. The widget has a voice recording option (the mic logo). Clicking on the mic results in a crash of the browser.

This behaviour can be observed within Bliss but as well within Trebuchet (so likely not Launcher specific).

Currently, /e/ is currently not able to tread voice commands. Nevertheless, instead of crashing, the click of the mic icon should simply be ignored.
