To turn on the email notifications in Outlook, open the app and go to “File > Options > Mail.” Now, enable the Display a Desktop Alert checkbox under the Message arrival section. Click OK to save the changes.

Thank you Willjoe. Perhaps I should have made it clearer, - I am referring to Outlook Web Mail in, not the Windows 10 Email app. I have the Windows 10 Email App (notifications are set to:- on banners and sound), but I'm not using it for my main email because of problems with it, so I am relying on the web mail in FF and I need reliable notifications.

In any case FF should not be altering my settings, that is down to me!

This is not a browser issue, but more of a cookies issues. You will need to tweak your cookie settings to allow live.com to store cookies. see screenshots I made a the changes and after closing and reopening my browser, I noticed that the setting stayed on.

Thank you Jonzn, I have entered Outlook Live to the cookies/exceptions in FF, as you suggest. I dont know if this will solve the problem though as I have never deleted any Outlook or MS cookies, although I have done this with Bing cookies. I will have to wait and see.

What are your settings for cookies when Firefox is closed. I just logged in to my computer and Hotmail to verify that the setting is still on and it is.

In case you use "Clear history when Firefox closes" or otherwise clear history.

• do not clear the Cookies
• do not clear the "Site settings"

• Settings -> Privacy & Security
  Firefox will: "Use custom settings for history":
  [X] "Clear history when Firefox closes" -> Settings
• https://support.mozilla.org/en-US/kb/delete-browsing-search-download-history-firefox

• using "Clear history when Firefox closes" in Firefox 102+ honors exceptions and keeps cookies with an allow exception, previous versions removed all cookies
• clearing "Site settings" clears exceptions for cookies, images, pop-up windows, and software installation and exceptions for passwords and other website specific data

To Jonzn - I'm not sure what you mean by checking cookies when FF is closed. How can I check FF cookies or settings when FF is closed? I am using Windows 10 and Windows 10 Mail & Calendar app- but as previously stated I am having some problems with that, so for the time being I am using web mail in both FF and MS Edge. Web mail settings I would have thought, are in the "cloud". Therefore I would have expected that whenever notifications are turned on or off, that the setting should remain the same, regardless of cookies, until I change it. Any such changes made, would be applied in all browsers and on all the devices that I access Outlook web mail from. It seems from what you have posted, that this expectation is incorrect, but anyway, as below I do not delete any cookies involved with email.

To Cor-El -As above I do not have FF set to clear cookies when it closes. I never clear all cookies, although I do sometimes clear cookies for certain sites I visit, for privacy/security(spam avoidance etc.), but never cookies for Mozilla or fo rany of the email providers that I use. Thank you both.

Thank you all for your responses. I tried the solutions you suggested. The problem seems to have gone away, at least for the time being. I'm not sure whether this has happened because of the adjustments made or which of them has caused th solution. Anyway, Thanks again all, Steven Kiernan.

Mark you post as resolved and have a good day.  ;-)
