"URL Replace" is an addon that moves Nitter, Invidious to alternavie frontends. Invidious has an existing addon for Friendica that allows customised settings. If both addons are activated in parallel, this leads to multiple link references, which do not look nice and are a hindrance. In addition, selected URLs can be redirected to 12ft.io.
This addon removes the Invidious link and replaces it with a link for Instagram links to proxigram. Nitter and 12ft.io are still part of the addon.
