Since switching my default browser from Safari to Firefox on my iPhone, I’ve noticed that deep links aren’t working like they used to. For example, an Instagram link that I received through a WhatsApp message used to open the Instagram app, or a LinkedIn link I received through Gmail would open the LinkedIn app. But now they open Firefox instead, which asks me to log in to the web app. I don’t see a Firefox setting to get deep links working again. The “Block Opening External Apps” setting is turned off.

Can someone please help? Thanks.
