Failure of last Firefox update

Firefox 更新失败
Robert Comba
Robert Comba

I had renewed my subscription for MS365 on Tuesday the 30th when I got a popup inviting me to update Firefox to the latest release. I agreed and the download appeared to have worked. However, I soon found I could not access any of the MS365 apps. I restarted and found Firefox had also disappeared. The icons are present in the list of apps but clicking on them gets no response.

I have deleted and reinstalled Firefox and downloaded a new MS365 with no change.

I have Norton online antivirus and the MS365 comes with continuous Defender using Malwarebytes. (I am running down the remaining Norton subscription). I have also used both to do a sweep on each but no problems were found.

I have Outlook which has not been affected.

I am coming to the conclusion that I may need to do a full deletion of both. Can anyone suggest any other way to deal with this?
