YouTube links open in different browsers

Mac
#1

G’day,

Firefox is my default browser. When I receive an email in Apple’s Mail app, and click a link, it opens in Firefox - Except for this morning, when I clicked on a YouTube link, and it opened in Safari.

Odd.

Tried again.

Safari.

Odd.

Tried one of the other links in the same email from YouTube - opened in Firefox! Tried the original link again - now it opens in Firefox.

Cannot figure out why this happened… but was frustrating when it did.

cheers

Some links only open in Safari I’ve noticed, despite setting a default browser other than it. I was sure there was a terminal command to fix this but buggered if I can find it again.
