Thunderbird-Hilfeforum

In the last two days all of my messages have been immediately marked as read (i.e., unread messages do not show up in bold). In options I have chosen 'Automatically mark messages as read after displaying for 10 seconds', and in the past this has meant the incoming message showed as bold until I opened and read it, and that the main display indicated how many unread messages I had. I am using Firefox 78.13.0 in Windows 10, but this did not happen after an update: it simply happened overnight. Just now I sent a message from my Gmail account to my Firefox address and have not opened it in Firefox: on my iPad it shows as unread, but on my PC it shows as read, even though I haven't touched it. This problem applies to all three mailboxes in the Firefox account: when I look at the main Firefox display, there is no bold to indicate that any of the mailboxes have new messages.

 This is very annoying in terms of business--I can't immediately see whose messages I have not yet read, and whether any new messages have arrived in a particular mailbox since I last opened Firefox (it is too distracting to keep it open all the time).  Many thanks for any help.

My question was why does cursor disappear in Mozilla Thunderbird email. I did not find answer in forum, but worked it out... Open Windows start menu. Type mouse. Open mouse / Advanced Options. Find "Hide cursor when typing" box... uncheck it. Fixed. Hope that helps someone!!!

How do I change "POP" server to IMAP server? Verizon default to AOL requires an IMAP address. Putting new IMAP address in doesn't work unless the server type is changed. You can't delete it and change it in "server" settings. This 77 yr old needs more guidance please.

Outgoing SMPT doesn't need a change. Thank you.

Emails arrive in duplicate, and when deleted they come back again, and again. This is a recent development although I recall having this happen several years ago, but I don't recall attempting to fix the problem, so it must have corrected itself. Assistance would be appreciated to correct this problem.

Thunderbird adds a double-space when you hit Enter in email messages. Is there a way to make it single-space? I've looked around on Settings, etc. and can't find one.

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Connection refused - OXSUS003_101 - https://postmaster-oxsus.vadesecure.com/error_codes/#_101.

Following a change of password with my service provider, I can receive emails but cannot reply or send new emails. Tis is the error message: " Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) mail.btinternet.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'."

Efforts to check or edit my Outgoing server (SMTP) password have proved a waste of time. Despite following all available instructions, screenshots, and online comments, I am unable to change or check my SMTP password. I am able to select 'Password' authenication, but not able view or edit the password. I have deleted that particular account and set up a new one with the same email address, but authentication problem remains. I have spent too much time trying to resolve this issue, so now I have no choice but to use annoying 'Windows Mail'. If I cannot resolve this issue, I will have no choice but to bid a sad farewell to the otherwise reliable Thunderbird which I have used for years.

I'm getting the following message when trying to delete multiple messages at a time. Sometimes it actually puts them in the trash folder but doesn't remove from Inbox. I've emptied the trash & did a compact folder. Still have problem.

The messages could not be moved or copied to folder 'Trash on cindyr@neo.rr.com' because writing to folder failed. To gain disk space, from the File menu, first choose Empty Trash, and then choose Compact Folders, and then try again.

Deleted messages used to stay in my Deleted or Deleted Messages folders until I manually deleted them. (I kept them for several months in case of late disputes with correspondents). However, they are now vanishing after a few days. Retention policy on each is 'Use my AC settings' and 'don't delete messages.' Any advice please?

how and where do I set up "Safe Senders" in Mozilla Thunderbird? Have looked at some previous anwsers but they all refer to using Options setting which isn't available in Thunderbird tools tab
