Question 1 - Is this a real version? (as dlsplayed in troubleshooting information) Question 2 - How can I upgrade to version 115,, or do I have to delete and start again? Sub question - if I have to delete what is the best method? I just spent a few days installing and then installing 5 gig of settings and mail from Windows 10; I would hate to do it again.

Hi, hope someone can help please

By mistake I set up my 89 year old aunties TB using a Beta version. All of her emails are in that profile. I then installed the stable version but I'm told that the stable version is an older versions and can not import from the Beta.

Specifically the Beta version is 127.0b4 (64-bit) and the stable vesrion is 115.11.1 (64-bit).

Is there any way to recover the emails (and if possible the settings) from the Beta profile to the stable release

Thanks in anticipation

I don't lnow. That is why I am asking for help. 1). I have installed Thunderbird on my PC and have your Icon on my desktop. I have a Domain, 'handmadebooks.co.uk hosted by Go Daddy.I want to move my email address chris@handmadebooks.co.uk to the Thunderbird’ icon.

2)I haven't used Thunderbird for sometime. I used to click on the icon and a standard window would appear featuring messages, new and oldbut that doesn't happen anymore. I don't want to find the original page because I will probably lose contact again My IT skills are very limited thanks guys, Chris’

Hello.

I read that thunderbird works with Microsoft 365 and modern authentication. I tested with Microsoft 365 accounts and it worked fine. The problems come with an accounting of Microsoft 365 operated by 21vianet service.

I configured according to https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 with the IMAP and SMTP settings from https://support.microsoft.com/en-us/office/settings-for-pop-and-imap-access-for-microsoft-365-operated-by-21vianet-ca51235d-afc5-4d7d-843c-3616a37d5771

It complaints "The IMAP server partner.outlook.cn does not support the selected authentication method. Please change the 'Authentication method' in the 'Account Settings | Server settings.'"

In SMTP settings there is no option to configure OAuth2

If you are one to search around for Thunderbird releases, you may have stumbled onto 127.0 from an unofficial site. I recommend you NOT use it. It is a beta, but not on the beta release channel. It is not intended for general use. Please ONLY use official releases from https://www.thunderbird.net/ If you do install this version, you will be presented with a warning message (see attached).

I've been using Thunderbird for years with no issues but suddenly this week it froze and although I could send e-mails from my Mac (running on Sonoma 14.5) I couldn't receive any. There was no message error, just nothing happened: it was frozen. So I finally opted to disinstall and then reinstall Thunderbird and now have incoming messages again but everything else I had: all my tags, e-mails older than a day ago, my address book have all gone. I've tried doing "import from profile "default" then choosing to import accounts and settings, address books, and mail messages but just get a message that "import failed unexpectedly, more information may be available in the Error Console" but I've no clue how to find the Error Console in question. Can anyone walk me through how to fix this issue and recuperate my old Thunderbird account without using all sorts of technical terms? I'm not IT-fluent! Many thanks.

So After today update i lost my session, all the tabs gone. All i can do i going through miles of history. No recent closed windows no session restore. Had it on my phone - managed to get one (no option to send all to device, only one by one) but the moment it synced gone there as well, apart the one i sent to device, of course. 127.0 64bit.

A firefox support article told me to reinstall firefox from snap on ubuntu, without mentioning anything about the profile, settings, and bookmarks. Now everything is gone.

Is there any way to recover my local profile?

I don't think it was synced properly with my other devices

Hi folks,

I'd like to obtain some clarity on provenance aspects of Firefox released as a Flatpak.

I see in this article that one of the options is to use flatpak package: https://support.mozilla.org/en-US/kb/install-firefox-linux

Is this article produced / reviewed by mozilla? Is flatpak an officially trusted, backed by mozilla, means of installing firefox on a system?

On flathub one can observe the "Verified" seal which indicates that such package is developed and maintained by original package developers (in case Mozilla). One can also observe in multiple forums here and there that mozilla is the one that builds and maintain this package.

Though a seal is nice, and users opinions are ok, it would be good to have artifacts that would evidence better this relationship. Also, would be good to have this officially stated in mozilla's website, under "Download options and other languages" section, something like "you can also safely install firefox through the flatpak package available on flathub which is developed / maintained / signed by mozilla itself".

Or maybe all of this information is around and i am just not able to link it together.

Thanks

I get the infamous "Unable to connect to your IMAP server. You may have exceeded the maximum number of connections" error in Thunderbird. I just moved to a new Windows 11 laptop but have signed-off the old unit and old phones, leaving just two devices in Google / Security. Obviously, I have reduced the IMAP connections to 1 on the PC. Still, I cannot get emails on this new PC; before reducing the devices, I could get emails on the old PC, the new phone, an iPhone, and an old phone. Turning off the fire wall does not help. I have done many variations of uninstalls / reinstalls on likely combinations of devices. I won't repeat those here but the net outcome seems to be: uninstalled / reinstalled Thunderbird - no effect

shut down new computer and fired up old computer and Thunderbird retrieved new messages immediately

downloaded and installed eM Client - immediately connected and retrieved new messages

downloaded and installed MailBird - immediately connected and retrieved new messages

started Thunderbird and received the too many message.

I just finished a round of installing / reinstalling Thunderbird but with all the AppData/Thunderbird/ folders / profiles deleted. The Wizard failed to identify the server information, which I supplied based on the three sets of working parameters (Tbird, eM, MailBird) but the error this time was a could not connect due to the Username and Password not agreeing.

I don't want to give up Thunderbird but I am out of patience. Please advise if there is some hope for a software fix. I have wasted too much time on this already pursuing a universe of possibilities. Thanks, Don

All of a sudden, I can't download any attachments, no matter what file type it is. I've reset Firefox to it's default, restarted, everything suggested. I don't have the first clue as to what this is.

I'm using Ubuntu 24.04 and just reinstalled for unrelated reasons. I'm trying to copy my Firefox profile over from my backup to the new installation.

I used the Ubuntu Snap store to install Firefox and put my old profile in -- this is the one that I was using on my previous Ubuntu 24.04 installation just a couple days ago -- and everything seems fine, but I do see this error message:

[ERROR error_support::handling] suggest-unexpected: Error opening database: Incompatible database version: 18

It gets printed when I type things in the search bar, so it seems related to some sqlite database related to history and autocompletion.

Is there a way to fix this? I'm fine with just deleting it, so long as the other parts of the profile remain.

(This is a strange error, since after all I was using the exact same setup -- Firefox on Ubuntu 24.04, installed via snap -- just a couple days ago, and it was, as far as I know, up-to-date.)
