Hi,

I used to scroll up in current message using Shift+Space, but it stopped working for a few days now. it's not mentionned in moving around TB, so I don't know if it was normal behaviour or a feature added by TB's arch maintainer.

Cannot send or receive email all of sudden in Thunderbird. When I the click the messages icon, nothing happens, and I get "Could not connect to server mail.twc.com; the connection was refused". When trying to send a m,message I get "Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.twc.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again." No settings were changed and everything was fine when I put the computer to sleep. This happens on both a Win 7 and 11 machine Email is a Time Warner (now Spectrum) Road Runner account (twc.com). Spent an hour with Spectrum, and they say this is a third party (Thunderbird) issue. A friend has the same setup, and is having the same problems that started at the same time. Win 11 version 150.02 Win 7 115.18.0 (latest available for win 7)

Appreciate any help....

some time ago my email provider (verizon) sold service to AOL. Since then ihave not been able to get email on thrunderbird. Woud really like to return to using thunderbird. What can I do?

How do I make Thunderbird open a new window instead of another tab? When I open a PDF file, setting, address book, or other, it always goes to a new tab. When I want to close this file, I often forget it's a tab and close the whole program! Annoying! I want these thing to open in new windows instead where I can hit close without shutting down Thunderbird.

Thank you as always. I am using Windows 11 and Thunderbird 153.3.1esr. When I open past newsletters using "Edit as New Message," I cannot create a line break by pressing Enter before the first character of the body text. Line breaks work elsewhere in the body text and in regular new emails. This mainly occurs with group newsletters. If I change the formatting to [Paragraph] and then switch back to [Body Text] with Ctrl+Z, I can create line breaks in that editing screen. Is there a permanent fix?

how much space can i add to Thunderbird if i want to send a video or file without adding a n app r to do it. Where it says add files how much can iput thee can i go like 500 or more

My emails are not downloading even though it says I have messages and they are downloading it just eventually stops and nothing is downloaded. This has been going on for several days. I made sure that my app is up to date and it is. I shut down the program and restarted my computer this also didn't do anything.

I recently installed Thunderbird on both of my Windows 10 PCs.

I have two email accounts:

axxxa1@shaw.ca

and

axxxa2@shaw.ca

The first account worked perfectly upon completing the Thunderbird set up.

The second account does not work and I have spent hours playing with various Configuration options.

It's very strange that BOTH of these email address successfully pass the "Connection Security" test.

I'm out of ideas.

Incidentally, I still have Eudora 7 on my PC and BOTH emails are working fine in that application.

Hopefully, you can assist me to resolve this problem.

Bonjour. Plusieurs onglets correspondant aux messages ouverts dans thunderbird se sont fermés brusquement. Je voudrais savoir comment les réouvrir. Merci de votre aide.

I'm trying to setup Netzero email on Thunderbird. I get the error message, posted in question. Outgoing mail works but can't load inbox messages. I got the following error message when I first started Thunderbird - "The STAT command did not succeed. Error getting message numbers and sizes.Mail server pop.netzero.com responded: POP access disabled"

I have a completely vanilla install of TB fully up to date as of this writing [it is version = 156.0.1 (aarch64) and I checked for updates], no extensions, no proxy, on a new OSX 27.0 (Golden Gate) computer and even when idling it is using substantial resources. The only thing even remotely non-basic is their is the Proton Mail Bridge to connect to Proton Mail for one of the linked email accounts, but that is its own little program with its own threads and takes almost no system resources even when sending or receiving mail (which is not happening currently.) Look at the attached screen shot.

In the screen shot I have left Thunderbird to idle for about an hour. No new mail in that time and other then clicking on or off the window to bring it to the fore I have not interacted with the program at all myself. Meanwhile Thunderbird and its Thunderbird GPU Helper are using substantial amounts of the CPU and GPU, have a combine total of 86 threads (more then any two other things running except the kernal tasks) and are hogging ram (not depicted).

Meanwhile among a few other applications (Apple Music, OfficeLibre, etc...) I also have Brave Browser opened in the background running with two windows and a total of 8 tabs wherein Brave is actively downloading GB of data from MEGA as well as performing other admittedly lighter tasks. Even when doing all this, Brave barely registers on computer resources compared to Thunderbird and Thunderbird GPU Helper when they are just idling.

Is this all proton mail's fault with the Proton Mail Bridge? If not is there anything I can do to quell the hunger for computer resources of this voracious beast of an email client that is TB and uses resources as if it were a video game even when idling?

My email account is handled by a university that uses Office 365-based Microsoft system for email accounts. My institution now requires that email client programs us MS Graph for authentication. Does Thunderbird 156.0.1 have this capability?

I use Thunderbird on multiple computers, sharing an NAS. One is Windows 10, one is Linux Mint. Both have Thunderbird 153.3.1esr installed. The email Profile and email file storage is on the NAS. The "home" folders on both machines have a profile.ini file that points to that shared profile. This worked fine for many years.

For perhaps 6 months i've only accessed email from Windows. Now i'm trying again to access from LinuxMint. It no longer works.

From Linux, at startup, Thunderbird complains that i'm trying to open my profile from "an older version of Thunderbird". A popup dialog claims "A newer version of Thunderbird may have made changes to your profile which are no longer compatible with this older version. " It offers to create a new profile.

First, the same version last edited the profile as is reading it. Second, i don't want to create a new profile, as the existing one has multiple email accounts at multiple domains, with multiple sigatures, and custom storage paths, etc. I tried profile manager, but it just takes me back to this dialog.

How do i get Thunderbird to use my existing shared email storage ?
