How can I change which browser the Mac Reminders.app uses to open "this webpage" associations for a Reminder, so I can change the "Open Google Chrome Canary" notification button to an "Open Mozilla Firefox" button?
Given I've created a Reminder for a Webpage on my phone by asking Siri to "remind me about this tomorrow", when the Reminder appears on my laptop running the latest public build of OS X, then I expect the Open button to offer to open it in my default browser, or just not mention the browser and behave as
Instead, what I see is "Open in Google Chrome Canary":
This has me flummoxed: I open that browser like once a year, and my default browser is Mozilla Firefox. I've no clue why Reminders has latched onto it as The Chosen Browser for webpage reminders.
ETA: I have deleted Google Chrome Canary. After relaunching Reminders.app, webpage reminders show, instead of its icon, the "invalid app" default icon with slashed-circle. Clicking that button does nothing. No console logs appear. 💯
