I am having icloud calendar issues in the firefox browser. Recently apple changed some of how their calendar looks in a browser. At the same time I began noticing icloud calendar events are getting messed up in firefox. Events from the day before are often missing. Events on the current day are 5 hours later. However, if in another browser, like Brave & Chrome, the calendar events are correct. I prefer to use Firefox. If you have any helps for adjusting things on my end please let me know: bygrase@gmail.com. Thanks, Cliff
