Hey there! It seems like you're dealing with Firefox popping up and grabbing focus on your Mac. No worries, we can sort this out. To stop Firefox from stealing the spotlight, here's what you can do: Open Firefox, click on the three horizontal lines in the upper right corner, then choose "Options" or "Preferences." Next, head to "General" and scroll down to "Browsing." There, you'll find an option called "Raise Firefox when a URL is opened from an external application." Just uncheck that box, and you're all set! That should keep Firefox from jumping in front unexpectedly. If the issue persists, try restarting Firefox. Give it a go and let me know if that does the trick!
