Mozilla added the path of the Firefox binary to the web browser's support page in Firefox 69 to make it easier for Firefox users to find out from where Firefox was started.

Firefox's aboutupport page offers a wealth of information: from links to the profile folder and update folder over information on the multiprocess status and browser version, to modified preferences, installed extensions and Mozilla installed extensions, and WebRender information.
