Thunderbird Community Forum

I'm on Windows 11.

Moving Thunderbird to the system tray was working correctly in previous versions, but since the latest update to Thunderbird 1560.1, clicking X sends Thunderbird to the taskbar instead of the system tray.

Thunderbird is not pinned to the taskbar.

I have also tested the setting with the option disabled, restarted Thunderbird completely, then enabled it again and retested. The behaviour is unchanged.

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 been through all the steps and configurations and everything is set correctly but suddenly Thunderbird does not communicate with Gmail. I have tried everything. My passwords are correct and IMAP and STMP configurations are all correctly set. Now what?

156.0.1 RSS subscriptions function normally Clicking on "Manage Subscriptions" button in "Account Settings - RSS" does nothing. Running in Troubleshooting Mode doesn't help.

Thanks,

Steven

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?

win11 :Thunderbird will not launch, It appears the issue is a Background Process labelled "Thunderbird" which is unresponsive to "end task" in Task Manager. Will launch after reboot.

I have no clue as to how Tbird into this state, but it has happened more than once

Thunderbird Version 156.0.1 Build ID 2026092215180

I am using Thunderbird on Windows, and I want to hide the yellow “Your privacy is protected” notification bar but still have the privacy protection enabled.

I tried to use a userChrome.css in my Thunderbird profile; here is the path; (C:\User\AppData\Roaming\Thunderbird\Profiles\lz1po89m.default-release\chrome\userChrome.css). I also set toolkit.legacyUserProfileCustomizations.stylesheets to true, but the customization does not work.

If anyone can please help and/or advise me on the correct procedure or CSS selector for this version I would be very much appreciated.

I was having trouble with Thunderbird outgoing mail. I changed some settings and it still didn't work. I tried to log in to Thunderbird and now cannot log in at all. I have 25 years worth of email in this account!

When several Lightning Calendar Reminders are in a popup window list, addressing one Reminder is causing some, or all, other Reminders in the list to vanish. This happens whether Snooze or Dismiss are selected for an individual Reminder.

Hello.. I was deleteing some mail in my inbox and then the program burped and said there is no more space. I tried to download new mail and got the no space message when I noticed that the whole inbox was gone.

I managed to recover the inbox folder and now I'm trying to put it back into the email program through windows explorer but when I try to paste it into the folder with the index.msf file I get the error that I don't have permission and must have administrative permission to copy the folder. I went through the properties and security tab and gave "everyone" full permission for the inbox, but it still won't let me past the folder back where it belongs.

How can I get the Inbox with it's mail back into my Thunderbird program?....

I'm using a Lenovo laptop with Windows 11.

thanks, David

Repeated attempts to log in using the window presented continue to fail. My password is correct and I am able to log in on the spectrum website without problems. I have two email accounts in TB ; one with Outlook.com and the other with Charter.net. The Outlook account logs in without problem but the charter account continues to give me the message that the login failed (image attached). When I go too the account server settings in TB for charter and do a test connection under security settings, a connection is made without a problem (image attached).

I believe the previous version (156.0) was working but there seems to be a rapid succession of changes coming down the pike lately. I have had intermittent problems of this nature in the past 4 or 5 months so it's difficult to keep track of which versions are successful.

Help please. I am not thrilled with spectrum but I do not want to change my email address.

Hello,

There is apparently a bug in the latest release of Thunderbird, which has broken the callbacks for Yahoo! IMAP email using OAuth. Potentially, it may actually be a problem with Yahoo!, and how https://api.login.yahoo.com is attempting to reopen Thunderbird after logging in, as the process has changed. I've already reverted back to the ESR Thunderbird channel once, but on a recent update the issue was reintroduced. Screenshots are included.

Thanks for any assistance.

I had to reinstall Thunderbird after doing a clean install of Windows 11.

Since installing, the expected login popup for Gmail doesn't appear. I get the attached error message instead.

Yahoo worked fine after a few tries. What is the problem here, and how can I fix it?
