Hi, thanks for reporting. Can you get some debug logs

1. open Config Editor from Settings page, set mailnews.pop3.loglevel pref to All
2. open Error Console
3. trigger a "Get Messages"

You should see logs like

mailnews.pop3.1: Connecting to pop://pop3.localhost:110 Pop3Client.jsm:125:18
mailnews.pop3.1: Connected Pop3Client.jsm:259:18
mailnews.pop3.1: S: +OK Dovecot (Ubuntu) ready.
mailnews.pop3.1: C: CAPA 
mailnews.pop3.1: S: +OK
CAPA
TOP
UIDL
RESP-CODES
PIPELINING
AUTH-RESP-CODE
STLS
USER
SASL PLAIN LOGIN CRAM-MD5 GSSAPI NTLM EXTERNAL
.
mailnews.pop3.1: Possible auth methods: USERPASS,PLAIN,LOGIN

The part I need is the CAPA response

I tried following your instructions but I do not see Config Editor etc., plus I am afraid to change anything what-so-ever.

This are non-destructive changes, there is nothing to fear.

1. Open Settings
2. type Config into the find field
3. click on Config Editor
4. paste mailnews.pop3.loglevel into the search
5. click the pencil icon on the right
6. Change Warn to All and click the checkmark
7. open Error Console in Tools > Developer Tools
8. trigger a "Get Messages"
9. Check the error console

OK. I did what you said but I the Error page does not provide a copy/paste function so here goes. I see some lines with yellow and white backgrounds but I concentrated on the lines with white background.
I see CAPA. It says "mailnews.pop3.104: C: CAPA". Below that line it says "mailnews.pop3.104: S: +OK".
The "mailnews.pop3.104: C: CAPA". changed to "mailnews.pop3.105: C: CAPA". The number 104 and 105 being the only difference.
I still have it open but can get a new one if you wish.

Note that there are six lines below "+OK" These are:
apop
pass
top
uidl
user
.

Also there are some lines in red letters which say "about:preferences : Unable to run script because scripts are blocked internally"

Thanks, these lines were lowercase in your Error Console?

I will make a fix.

Comment 8

[attride]

Yes. Those six lines are lowercase in the Error Console screen. It does not allow copy/paste. If it did I would have copied/pasted.

Comment 9

[Ping Chen [:rnons] (away)]

Right click > Copy Message or Ctrl + c should do it. Anyway, I know the problem now, thanks.
