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

Chosen solution

I tried restarting Firefox in Safe Mode and I can access all features of Outlook correctly. = I see multiple Ads now, but disabling the ADP did not give me this level of capability within Outlook.

I will have to save all my extensions and refresh Firefox, then install only the extensions that I want at this time.

Thanks very much jonzn

I have just updated firefox to v104.1 and my experience with Outlook is the worst that it has ever been. Outlook would not load, I cleared the cache and logged in. I tried to delete 1 message and outlook got stuck, no further interaction. Total time: 1 min of use.

Outlook is un-usable on FF104.1 Number of cookies: 111 Size of Cache: 27Mb

I disabled Ad Blocker Plus (ABP) and restarted Outlook. I am seeing a difference in the behavious within Outlook for the first 5 min. I can delete messages, and Outlook still works - something that was not happening after the upgrade.

I initially whitelisted live.com, with some issues. I then disabled the ABP plugin and retested Outlook. I am still monitoring the situation, but things are not good.
