I have Thunderbird on my Omen 35L on Win 11. Thunderbird CANNOT CONNECT to Comcast to send an email. This was not a problem on Win10. I have done ALL the settings fixes and NOTHING WORKS. Other mail provider accounts send OK (e.g. Site Ground). This is unique to Win 11 and Comcast.

Good day,

On one of several computers we use to access email when we try to 'Get Messages' Thunderbird doesn't even attempt to connect to the mail server on two of the accounts set up. All four other computers access the servers just fine. In trying to resolve the issue on the recalcitrant computer I created a new email account with the host and added it to Thunderbird using the 'Add Account' wizard, and changed IMAP to POP3. Once the account was created it logged in and received the 'settings' email from the host, and I was able to send an email to another account. I could see the activity reports for the new account in the status bar. However no reports on the status bar for the original two accounts. I've triple checked port settings etc and up until a few days ago Thunderbird worked just fine on this machine. No changes have been made to the original settings. Prior to adding the new account, when asking to get messages the only report on the status bar was 'Done' without any information reported about contacting, downloading etc. The Done message showed up immediately upon clicking the Get Messages button.

Adding the new account and it working properly tells me my settings are correct and the install of Thunderbird is working. Thank you in advance for your suggestions.

After running updates and restarting my computer, I am no longer able to open my common websites used frequently. I don't know how to fix this problem. The search bar runs until it times out.

My home desktop computer is asking for a network login to access the internet today, after FireFox crashed. I do not see anywhere to login. Please help. I have a Mini Mac. I am at a library as my internet is not working.

Thunderbird is reporting error "could not connect to server . . . the connection was refused." However, it seems that it reports this error only when there is no new incoming message. And it does not happen consistently.

Thunderbird is version 147.0. Operating system is the current version of Windows 11 on an HP desktop workstation, new 4 months ago.

I have 4 email accounts set up in Thunderbird. Server settings for the accounts are set to check for new messages at startup and at intervals of 5 to 10 minutes depending on the account and to automatically download new messages. I have confirmed the server settings for the accounts match the settings specified by the ISP. When there is a new message to be downloaded it seems that it does, in fact, connect automatically to the server and download when Thunderbird does its check for new messages at startup or specified intervals.

When I have open the Inbox for an account and click on the "Get Messages" icon or right-click on the account name and then click on "Get Messages" I usually promptly see at the bottom of the window the messages "Host contacted . . . sending login information . . . Checking inbox for new messages . . . there are no new messages to download." That is true even if I do that within seconds of receiving the "could not connect" error. But sometimes there is a delay of many seconds before the "host contacted . . ." message, and occasionally I never get that response to the click to get messages. When I click to "get messages" I never see the "could not connect" error even if the "host contacted" message does not appear.

I have set to show an alert and play a sound when new messages arrive. The same sound is played when the "could not connect to server . . ." error is displayed. The result is the sound may be played every 5-10 minutes. I can tell that this issue does not happen consistently because I might go for several hours, or even all day, without the sound and without the error message. The occurrence or absence of the error seems to be completely random and unrelated to what I may have open on the computer.

Since I do seem to be receiving messages without a delay in delivery this is perhaps no more than an annoyance, but I would prefer to avoid the annoyance. This is not happening on other computers here which are using Thunderbird.

My Spectrum-TB connect was functional yesterday but is not working today; NO password or setting changes! Contacted Spectrum and was able to successful send an email from Spectrum's online webmail to a gmail account.

Hi All, I have been sending emails through Android Thunderbird, but they aren't being synced to the server, so I can't see them anywhere else. I've set the Sent folder to sync (as well as the Inbox). Pressing the sync button just spins the indicator, but doesn't actually sync. When I try to move or copy messages, an error comes up saying that messages can't be copied or moved that aren't synconised. How can all my messages (sent, inbox, everything) be synced so that I can see them everywhere? I've just turned on sync debugging, will see the results soon.
