The issues I am facing with outlook mail seems to have occurred within the last 3 months. I have used outlook in Chrome and there is no issue. I have gone to the Microsoft site and there are several complaints that Outlook is not usable with Firefox. On my company machine, I limit my personal email to Firefox. Other web pages seem to be fine, just outlook mail. I use Firefox for most of my testing & personal and Chrome for corporate browsing. The issues start occurring after about 5 min, within the last month. I am a MacOS user and I have v.104. The issues face range from not limited emails listed, missing icons, javaScript drop-downs not working, not being able to delete emails, not being able to restore emails. When I refresh the page, more recently Outlook crashes. My cache for Outlook is around 13-14Mb. When I clear the cache, things are fine for about 5-10 min. When the page refresh fails, I get the following consistent error message:- UTC Date: 2022-08-30T18:49:33.551Z Client Id: 1069883F64C04966AFA704CEF4EF3E78 Session Id: a338a732-ad52-4dee-a388-43aac7dac2b8 Client Version: 20220819006.08 BootResult: cdnError Failed resource: https://res-geo.cdn.office.net/owamail/20220819006.08/scripts/../resources/locale/en-gb/owa.MailListItemThreeColumnView.json err: Error: Failed to load localized strings esrc: InitLoc et: ClientError estack: c@https://outlook.live.com/mail/0/?bO=2&sessionId=a338a732-ad52-xxxx-a388-43aac7dac2b8:341:116883 a/a<@https://outlook.live.com/mail/0/?bO=2&sessionId=a338a732-ad52-xxx-a388-43aac7dac2b8:341:116563
