About once per week, I'll be using Firefox and it will stop working. I'll close it and open it again and it gives me an error message "The application "Firefox" can't be opened."

If I download Firefox and reinstall it, everything will work fine for another week and then it will do it again. I'm not doing the same thing when it breaks. It does it on both my Mac Mini (macOS 14.5) and my Mac laptop (macOS 12.7.5).

It just started happening in May on both. Nothing has changed on both that I can think of.

I am trying to setup an Outlook account on Thunderbird and I get an error: "Unable to log in at server. Probably wrong configuration, username or password." I have an existing Outlook account which I am able to use on the Outlook app on Windows, the Android app and the web version on outlook.live.com I wish to have an e-mail client on my Linux Mint machine from which I can access my Outlook e-mails. To do so, I went to the 'Account Setup' page on Thunderbird and used these to set up my account: Your Full Name: <My Name> Email address: <email-id>@outlook.com Password: <My Microsoft password which I use to sign in to Outlook> Under Manual configuration: INCOMING SERVER Protocol: IMAP Hostname: outlook.office365.com Port: 993 Connection Security: SSL/TLS Authentication method: OAuth2 Username: <email-id>@outlook.com OUTGOING SERVER Hostname: smtp.office365.com Port: 587 Connection security: STARTTLS Authentication method: OAuth2 Username: <email-id>@outlook.com

I am sure that the password I am using is indeed the correct password. I still get an error as shown in the screenshot on the Account Setup tab. How do I resolve this issue? Thanks a lot!
