I have had my @yahoo.ca email for many years. I have always used Thunderbird to retrieve my email and read it locally on my desktop. Recently when Thunderbird launched Rogers take over and wants me to lo in to rogers. It is not a Rogers.com email address, it is a yahoo.ca email address.

Why has Rogers taken over my email.

I can still access my email on the web at the yahoo.ca website, but I want it back in Thunderbird as well.

I have used version 145 of Thunderbird "all my life". Until the other day when I installed version 146. I realize of course that development changes things, but I would like to inform you that a 93-year-old has neither the patience, energy or interest in learning the new Thunderbird. I therefore wish that someone would be so kind and send me the installation file for the previous version. (Unfortunately, my own one is in a computer that I no longer own.) Furthermore, I donated 194 SEK on December 26th when I downloaded the program. (And it wasn't the first time.) In summary: I would like to get the installation file for the previous version (for Win11, 64 bit). Best regards Hans Peter Wiehen

Recently, I have experienced an erroneous browser launch, simply by clicking on the title of the message in the list pane. This problem seems to occur when clicking on emails from a particular UK supermarket (tesco.com) and the web page opened has a long and complicated URL, but the page contains only a single pixel which shows up as a white dot on a black background.

Obviously, it is likely that there is something strange about that source, but the problem doesn't occur if I click on the same email in a different email client (in this case Evolution).

I have tried various Settings as advised by web searches and also the solutions suggested in Thunderbird Help (Troubleshooting Mode and Troubleshooting Information).

I am running Thunderbird 140.5.0esr (64-bit) on Kubuntu Linux 24.04.

Hello Thunderbird community,

I’ve been exploring Thunderbird’s integration options and noticed that while email sync with Outlook accounts works fine, calendar and contact synchronization with Outlook/Exchange Online is currently unavailable.

This is a significant limitation for users who rely on Outlook’s ecosystem for scheduling and address book management. I’d like to ask:

Is there an official roadmap for when Outlook calendar sync will be supported in Thunderbird?

Will Outlook contacts sync be added at the same time, or as a separate feature?

I believe many users would benefit from clarity on this, since full Outlook integration is critical for those working in Microsoft-centric environments.

Thanks in advance to the Thunderbird team and volunteers for any updates or guidance.

Thunderbird 140.6.0esr (64-bit) "On Linux LMDE 6" 64 bit, on an Intel platform. An HP small format desktop, using two screens.

I see this issue (below) when receiving digest mail from groups.io See the hopefully attached image. If that didnt come through, I can send you a whole screenshot if needed.

The issue is that the first line is correct. The "sender" is the group "linuxham" and is a mail digest message. The second line "Thunderbird 2025: A Year in Review" is correct.

However.. The third line from the UKMicrowaves group, another groups.io group configured to use "Digest Delivery" mode, is shown as coming from "[edited] @groups.io" Misleading at best! (It is always the linuxham group details that is used, regardless of which group has sent the digest.)

The last two lines are correct.

I see this on all groups.io group mail where what comes to me is in the form of a "Digest" (so as not to flood my inbox.) Does T'Bird handle "Digest" mails differently to one-to-one mails?

This odd labeling of the "Correspondents" started some time ago as a result of a past T'Bird update, but prior to that update, was not an issue. I have "Many" groups.io groups I'm a member of.

Sorry but it's taken me this long to find out how to submit this info and ask the question.

I'd love for this to be fixed, and am willing to test any trial version(s) that may be needed, and/or to provide any other needed system info that would help. I am contactable on [edited from public] @googlemail.com

Oh... I made "Many" attempts over the last year or three to setup a "Mozilla" account to report this, but I now know "Mozilla" has renamed to just "Moz". Sadly, "Moz account creds" are not accepted! to login here.

By accident I found that a Google ID works. Pity that was not sorted some time ago, else I could have reported this sooner. (Better presentation on the T'bird support initial web page would help with such confusion, or is this intentional to filter out lame questions? And lower support costs! I know of others who implement such! ;-)

Anyway, thanks for seemingly letting me in at last. Much appreciated from a long time Thunderbird user of "Many years".

Even with the above wrinkle, it's far the best mail client out there I find. True "Cross Platform" too. (Though I found the Android offering rather "clunky" at best.)

Thanks Again.

Yours...

Dave or G8KBV, yes a "Ham"...

Hi, I am transitioning from Mac, after 30+ years, to Linux. Part of this is making sure that certain heavily used applications can be relied-upon in Linux. A couple days ago I successfully installed Thunderbird and moved my Profiles into the Linux version of Thunderbird. (This really needs better guidance from Mozilla! What I found on the subject was definitely NOT accurate!! Instructions should NOT be identical for all platforms). In a cautious abundance of excess, I repeated the same transfer onto a second Linux machine. Now I have Thunderbird running on my desktop Mac Mini AND on two separate Linux machines. Eventually, it will be removed from the Mac. What I never expected was that every time I received, deleted, read, etc., email, the same action would occur on the other two machines, regardless of on which machine I made changes. All accounts are set up as POP accounts, BTW. How is this possible? are the three instances of Thunderbird aware of each other on my local network? Or, is there some sort of updating processing happening from my ISP? Regardless, I am thrilled that I can potentially use Thunderbird simultaneously on different machines, but... Down Side: Apparently, not everything is mirrored. I just moved a newly received email from the inbox to a local folder inside Thunderbird. That action was NOT copied on the other two machines. Is there anything I can do to keep ALL the folders in sync? Thanks very much.

1. I am getting Mozilla Thunderbird ESR notices pop up when I log on to my PC (W11). I checked my Thunderbird version and I have 146.0.1 and I am on the release channel so why am I getting these notices ? 2. Recently I noticed that when I try to move e-mail messages to a specific folder, I right click on the message and get the prompt Move To and then Recent Destinations where the problem exists. The list of Recent Destinations used to be in alphabetical order and now it is sorted by most recent destination time. This slows me down considerably. Please revert. Thanks !!

my thunderbird freezes at the point of checking mails. when i try to update it, it opens a new application completely and doesn't update my present one. i also can't find the location of the app or the data. pls help!!!

Hi all - I'm running Thunderbird (14.05) on a desktop Mac running Sequoia 15.7.2

In my Local Folders, I have sub folders which in turn have a large number of subfolders. All of those sub folders are automatically listed alphabetically as they're created. In the last couple days, a fairly random selection of six folders from topline folders, sub folders and subsub folders have been shifted to the end of the alphabetized list and I have absolutely no idea why. I can manually move them back no problem, but I'd really like to stop it happening again! Also, I've tried clicking on the topline folder and choosing to sort by subject, but it changes nothing. Even renaming an mis-listed folder to a new name does not make it move to its correct place in the alphabet. Any ideas? Thanks

This has happened to me twice now. I do not delete emails from purchases until the item is received. I leave it in my inbox and often will mark it unread. I went into it yesterday to check to see when I should receive a certain item and the email is gone. I have looked in all folders (spam, trash, archive, all mail) and it is not there. I blamed G-mail originally but now wonder if it is Thunderbird and if there is some way to retrieve it. Is there a defunct setting somewhere that I do not know about or understand? I have plenty of storage. Can someone answer this for me?

Hi. I access a gmail account via Thunderbird. It's generally quite efficient, but recently it has become very sluggish. I have pretty fast internet, wired at 1G, so usually my mail appears almost immediately. In the last week or so it has slowed down dramatically, sometimes requiring multiple login attempts. Any idea what's going on? Thanks. Steve

I've always experience occasional TB crashes. According to my log history there was 1 in July, 3 in Aug, 2 in Sep, 2 in Oct, and 6 in Nov. I never really paid attention since the reboot was quick. But now in December I am losing work and it is a major problem. I've had 30 crashes in Dec and 21 in the past week. I have only 3 add ons and they have not changed, and a Copernic connector. I disable the Copernic connector and it didn't help. I have the same 140.6 on my Surface Go with the same add ons, except for Copernic and it runs fine. On both PCs I use Malewarebytes and WinDef. I have put exclusions for them in their setups. Even with MBAM completely disabled I've still had crashes.

I cleared the Cache and no help. I've even had occasional crashes in Troubleshooting mode. Here are my last 5 crash IDs

bp-070bf941-4e8b-41a3-8b84-3e3440251224 bp-a936f7c2-9ee3-4c38-b304-dab830251224 bp-8be9cf9e-8f2f-49bb-95cf-47e780251224 bp-12f8fc2c-c505-40f0-8c67-44b730251224 bp-9013fb78-086c-4327-9de8-62db30251223

Interestingly I’m also experiencing crashes with Firefox, especially ChatGPT. I cleared the ChatGPT history and that helped but did not solve the problem. I cleared the Firefox cache and in troubleshoot mode still have issues.

Otherwise my win11 PC seems to be working fine. I’ve run chkdsk and all is ok. Also scannow is ok.

Is my next step a profile rebuild?

Win 11 and Thunderbird 140 not working and I have tried all the things I found on the internet and none of them work. I have tried cleaning my registry and deleted directories and uninstalled thunderbird re-started and it will still not work.

I guess I have to forget thunderbird. It is a shame.

Have TB on my laptop (146.0.1 (64-bit) on Win11) all set up the way I want it. Would like to "clone" those settings/profiles to my desktop. AI site said, "Copy profiles folder and profiles.ini to the new machine." Didn't work. Asking me to set up from scratch. Laptop is on "standard" edition, think desktop is on beta. Is that the problem? What do I need to do?

for some reason a few random emails will come to my iphone, but not Thunderbird on my Windows 10 PC. Not in spam, not anywhere but on my phone. Anyone else having this issue?

I use a private email server (mail.ragan.us. I have set up Thunderbird on Linux Mint 22 with the same email server settings I use on Outlook in Win 10 and Apple Mail on IOS 26 which both work fine. I created the account in Thunderbird and it showed success. When I try to get mail for gary@ragan.us,Thunderbird shows connected to mail.ragan.us, but will not download mail from that server. Any suggestions? Thanks.
