Campaign Calendar View - Chrome vs Firefox

Interesting - When I use the Campaign Calendar View in Chrome and Edge, my evening campaigns show up on the scheduled date. However, when I use the Campaign Calendar View in Firefox, the campaigns show up on the following day (i.e. scheduled for 8pm on a Thursday evening, will show as Friday in Firefox, and Thursday in Chrome and Edge). Why is this? I have been mostly using Firefox because of the issue of my saved brand colors not showing when using Chrome. Not having the calendar display properly is annoying.
