I’ve used both Mull and Iceraven on phone, Librewolf on desktop. I went back to stock FF and tweaked it on desktop because it was tuned differently than I wanted - Particularly when it came to dark mode support. On phone I always settled for Iceraven but it’s miles behind chromium forks when it comes to tab management (ironically, FF is miles ahead when it comes to tab management on desktop).
But what if they aren’t happy to chat on their coffee breaks either?
What you’re suggesting is basically just hitting the snooze button. “I’m sorry but I’m just the type of person who don’t do small talk.” in a polite but firm manner have worked wonders for me before.
