I have had very few notices about Thunderbird upgrades. My records show Setup numbers: 3.0.exe, 8.0.exe, 52.4.0.exe, 52.9.1.exe, 78.12.0.exe, and then 115.5.2.exe. My address book made it through all but the last upgrade. No notice that I should save a copy of my address book ever showed up in any correspondence. I tried reinstalling an old upgrade but the upgrade always wants to update the installation. I did try to reinstall 52.9.1, but the next screen wanted my name and password. It would not accept any name and password that I could remember. So I tried searching for them at Xfinity and Comcast to no result. I did not try my Firefox password because it didn't seem appropriate. Incidentally, my records show 135 upgrades for Firefox for the same length of time as the upgrades for Thunderbird. My fear is that my address book is unrecoverable. I chose Thunderbird because I ofigured none of it would need backup if it became necessary to reinstall Windows 10. Which happened last year. I did not expect Mozilla to change Thunderbird so drastically that I couldn't get every thing back. Sorry but I'm a senior citizen and not computer literate. If I have to try to recreate my address book I may as well use Microsoft's Outlook as it looks somewhat simpler than Thunderbird - which I doubt.

Hi ALL,

First off, once again, thank you very much for the best email application in the world.

Just to make sure, does the latest version of Thunderbird not support showing PDF in line anymore? I did check the settings of attachments to show and I did reactivate the view menu show attachments in line but still no joy.

Thanks a million for any help.

Hello. I was searching my Inbox for e-mails I knew I had, but they weren't showing up! After doing a general search, I found the e-mails in the search results. Then, I clicked "open in conversation" and they were all there and labeled with "Inbox" or "Sent" folder, respectively. So I right-clicked and selected, "open in containing folder", but it didn't work! The "containing folder" opened [i.e., the Inbox], but didn't show the e-mail! So then I searched manually by scrolling in the Inbox to the date of the "hidden" e-mail -- yet it wasn't there!

(In other words, when I did "open in conversation" from the search results, it showed the conversation, but I can't actually see the e-mails in their containing folder!) Besides for this problem, but I think there are a lot of other e-mails that are "hiding" in this way as well. What should I do?

Thanks for any help you can provide!

Sincerely, Jonathan Rosenberg

This problem occurs on My wife's and my machines. My wife has a printer. I do not. When we try to print the preview shows only a few lines or at best a half page. Even if we want to print multiple pages that's all that shows up. We have "print all" as the default setting. The problem started about a month ago. I think it has something to do with the newer versions of Firefox.

I am running a Mac Mini M1, on the latest OS, after upgrading my TB I have just had 2 force quit because of TB. As you will see it is using over 40 GB of memory, normally between 500 - 600 MB

I have turned anti-virus off, checked account settings and checked provider's access limit. I can receive emails in webmail, but not Thunderbird. I don't get any error message in Thunderbird, emails just won't come through.

Suddenly I can not receive my emails on Thunderbird. They do show up on my cell phone. When I send an email, I get the following, "Your message was sent, but a copy was not placed in your Sent folder due to network or file access errors. What can I do?? Ed PS I will get your email response on my cell phone, thank you.

I really like this app. I always use it on desktop also but after a few last updates I noticed that battery usage of this app increased a lot and the percentage is very high. 1 hour screen time on youtube was 4% battery usage but on the firefox side it was 17 min / 11% battery usage. If you fix this It will be perfect for me. Here are the screenshots with different days. And I'm using sync feature and ublock addon. I always close the opened apps and I use deep sleep feature on my samsung device. And I forced to close the app. For now I stop using firefox for test purposes.

I've had long conversations with Apple regarding the setup of iCloud email accounts on Thunderbird. The process must include the generation of an App Specific Password using Apples web page :

https://appleid.apple.com/account/manage

This generates a password in the form aaaa-bbbb-cccc-dddd which is a different password to be used only with one Windows APP. Apple insists this is working with their standard mail server settings preset by all the email client providers. I've been advised to refer to Mozilla Thunderbird and Apple are insistent they can do no more than mail me links to all the instructions I've already read in detail several times. However, I believe the problem lies with Apple but they don't yet know it. I've used separate ASP generated passwords and tried to install an iCloud email on several different email clients: Thunderbird, Mailbird, Outlook and Postbox. All these confirm that the settings seem to be valid but nonetheless the email account fails to load with error messages suggesting the configuration or password (i.e. the ASP) is wrong. The common factor is Apple not Thunderbird. I suggest anyone flummoxed by this awaits the acceptance of this problem by Apple.

Hello,

This is my very first post to a support community so please excuse me for any rookie mistakes and oversights.

T.B. 115.8.0 (64-bit) Windows 10 - IMAP settings with multiple domains and multiple accounts on each.

Problem/Issue: Most searches return the expected results, but in certain cases, and seems to affect mostly the sub directories in Local Folder (have not been able to replicate problems in strings found elsewhere).

Things I have already done: - Rebooted PC - Compacted the folder where the email resides - Repaired such folder - Confirmed that Global search is clicked for such folder - Opened the email to confirm that it does open and is valid (Remember that it's in Local folders so already downloaded)

E.g. Global search string "Re: New Project 25-301-623 needed into Swahili - word count 321" (which does exists in Local Folders) does not produce any results but (Deleted first character of the string) "e: New Project 25-301-623 needed into Swahili - word count 321" produced results for "New Project 25-301-623 needed into Swahili - word count 321" without the results for "Re:...". Additionally, no filters are displayed such as Location, People, etc. (Running the same search within the folder where it resides works fine.) Cutting down the string to only "Re: New Project 25-301-623" still does not find any results. Global search for string "Payable Summary for: August 2022", which resides in the same folder tested is found but no filter data available for Location, People, etc. However a search for "Project delivery for Job: 25-258-813" again residing in the same folder is found with Location, Account and People. I've tested same approach and tests on different folders to rule out Folder specific problems and behavior is the same problem.

Another example that might help in figuring things out. I tested a string of an email subject from an amazon order, which are long in nature do to # dashes, long numbers, etc. Performed a global search and the email was found but no Filters shown. Did the same search removing the end of the string "has shipped" and the email was found once again but with all Filters showing.

I hope I have been thorough enough. If any additional information is needed please let me know.

Thanks to all.

Since updating to Android 14, I have had this issue twice now. I notice that my phone has way less battery than normal at the end of the day. When I check what has used all of the battery, I see that firefox has used over 10% with only like 3 minutes of screen on time. Reinstalling the app seems to fix it, but I don't want to keep reinstalling.

I have Thunderbird, version, 115.6 on my iMac. Up until this morning I have had no problems.

First when I used "Get Messages" this morning it kept telling me there was an error with my server. But after the error was fixed by contacting the server, Thunderbird was no longer able to connect to the server any more. I can send messages ok and they go through but I can't receive them since "Get Messages" no longer works.

My Apple Mail program on my laptop works fine, so the server is back to working properly and I can pick my Thunderbird sent messages there.

How can I get Thunderbird to connect to my server again for incoming messages?

Thank you, Martha

Hi, Please advise how to remove, disable, delete, block the new added "Your browser is being managed by your organization." to my Settings page. I'm home user .Also Please know that this is generating "FALSE FINGERPRINT CERTIFICATES" thank you

I have set up a number of Message Filters to automatically run when new email is recieved. None of the run automatically on new email. This is frustrating on it own however I can’t even run them manually on individual filters for the inbox. I have recently moved to Thunderbird for my primary mail client from Mac Mail and definitely like it better, but filters not working and working perfectly in Mac Mail makes it difficult to switch over completely.

Microsoft Outlook sign in screen does not load on Firefox. Please see the attached image. Every time I need to read my mail I have to open Chrome , which definitely I want to get rid for good. Any solution ?
