iCloud Calendar Won't Let Me Edit on Firefox

Hi,

I noticed recently that I can't edit an event in iCloud Calendar using Firefox (version 118.02) on my MacBook Air (OS Monterey). Even if I've misspelled a word as I'm creating the event and want to delete a letter, it won't let me. The "delete" key doesn't seem to work. It will also not let me edit after I've saved the event.

But, if I log into iCloud Calendar on Safari no problem editing. I can also edit the event on my iPhone and it seems to correct the entry.

This is an issue for me because Firefox is my default browser and I'd like to be able to use the online calendar without having to correct errors on Safari or on my iPhone.

Any ideas??

Thanks!
