Thanks Julian.
You were right, I had a translator.js:49 var assign = Object.assign || jQuery.extend;
error that wasn't there yesterday and it turns out that this morning I was back running node v0.10.36, I had forgot to set nvm alias default v6.2.1
since that was the version I used to do my upgrade to nodebb v1.4.2.
Sorry about that! My bad.
Nevertheless, the error regarding the admin panel and the tab's name in Firefox is still there though.
This is what I get when I run a ./nodebb dev
error: Error: listen EADDRINUSE 0.0.0.0:4567

I still have to hit F5 on every admin page in order to get all the text.
