When I delete a message from the message list panel, my TB used to reach a state when no message is selected. Now, after a message is deleted in the list [classic view, message list panel], another mail is automatically selected. Is there any way of getting the previous behaviour? Thanks in advance, Max.

Whenever I get an email that says they are including an attachment, the attachment is never there. What is going on and how to I get email attachments. Any help is appreciated.

Thank you

I've been using Thunderbird on a Windows machine for years. I now have an iMac and recently downloaded Thunderbird to start transitioning over. When I try to set up an existing Email address, the configuration is found in the Mozilla ISP database. After I enter the password though (mobile.charter.net), I get an error stating "Unable to log in at server. Probably wrong configuration, username or password". The password is correct and works on the Thunderbird version on the Windows machine. I have multiple Email addresses and I get the same error on all with verified correct passwords. Any help to correctly install would be greatly appreciated!

I have uninstalled and re-installed several times and even the downloader throws this error once it finishes. I simply can no longer use the browser. This is a huge inconvenience since I saved so many links for my work. Please help.

We have a need to change the name on some bookmarks that we push out via GPO but despite updating the ADMX it is not working. Does this only work for Firefox for Enterprise or does the normal Firefox abide by these settings?

My Thunderbird email program ran into problems getting mail from Google. So I deleted the program and then installed it again, now it cannot log in to any email address I have. How do I rectify this? I can access the mail directly thru Google but I prefer you email program.

Hello my FFox is up to date on a new Samsung A07. TF1+ pop up says they can't play their video in my navigator (FF). Have I put on too much security? Cookies for site accepted, No adblockers. Please advise, thanks

If I try to add a bookmark to a folder, none of the folders I have created are listed. I am given the option to create a new folder to add it to; that works, but the new folder has exactly one bookmark in it and there does not seem to be a way to add any more.

Bei jedem Öffnen von Thunderbird bekomme ich mindestens 200 mal diese Fehlermeldung angezeigt. ich habe mit Mail Merge gearbeitet, jetzt jedoch deinstalliert: Dennoch permanent die Fehlermeldung. Wie kann ich den Fehler beheben? Siehe Screenshot

I'm trying to add a second email account from my domain into Thunderbird and on the password test page I get an error. Of course the server exists, my other email account also uses it. How do I fix this or is this a problem with Thunderbird?

I updated to version 146 today on Windows 10 and had to use administrator credentials. I have Mozilla Maintenance Service previously installed. I tried uninstalling MMS and then re-installed FF using full installer and selecting the custom option to install MMS. I cannot see the option in Settings..General 'Use a background service to install updates' (Screenshot attached) How can I fix this issue which has been present for some time?

I'm dealing with a properly updated 'bird: 140.5.0 (32-bit) running on an equally updated Windows 10 desktop. First thing this morning, out of nowhere, I started getting an "unable to write the email to the mailbox..." message when sending, thus I could send but not save. And then I realized I wasn't receiving either, on all three accounts in my Thunderbird. I stopped everything and focused on trying to fix this. It's been an all-day, losing effort. So far.

I tried the various quick checks and fixes recommended here and there: I'm running the program as an administrator. I restarted the program. I rebooted the computer. I think I have enough disk space, but to be sure I deleted some bloat from possibly overly large files. I compacted, even though the program is configured to do that regularly. I temporarily disabled my antivirus program. I went into my webmail and deleted all messages that have arrived since my Thunderbird stopped receiving, in case one of them was corrupted. And probably some other attempts as well. Nothing has helped.

And now a second, even worse issue has fallen from the sky. Thunderbird opens. The folder list is where it always has been. The number of unopened messages in each folder is there in boldface, as always, but...the folders are all blank and I get the dreaded popup: "unable to open the summary file...." Have I lost my years' worth of carefully curated emails?

I've tried folder repair. I've deleted parent.lock. Etc. Nothing. Nothing. Nothing.

I will be super-grateful for any wisdom sent my way.

The minimize, maximize, close line at the top of the screen is missing when Firefox opens. If I click the Firefox icon in the task manager to minimize it and click it again to maximize it, then the missing line at the top appears. This has been an ongoing glitch for a week or more. Perhaps you can fix this minor problem?
