I accidentally started the upgrade to 115 and aborted it. The "What's New in Thunderbird 115" now pops up every time I run the "old" version (102.15.1). It is my practice to close all running apps at night before I have the computer go to sleep mode. Consequently I have this message starting my default browser every time I restart TB. It has become annoying. There must be something I can do to stop this. I looked in all the appdata directories but couldn't find anything obvious. I also looked in the update directory but nothing obvious to me there either. Can you provide a fix for this?

I have not upgraded to 115 because too many people are having problems of one sort or another. I do not want to search for help to patch problems resulting from the upgrade process. When problems settle down a bit more, maybe then.

I have installed TBSync for my addresses/contacts. Syncing works correctly between Thunderbird and iCloud (both ways). However, new entries created in Thunderbird (although correctly syncing with iCloud on the net) do not appear in the Mac Contacts app on the Mac desktop. Strangely, these entries appear on my iPad Contacts app. It is only entries created in Thunderbird that do not sync through to the desktop Contacts app. Yet I can create a new entry in my desktop app and it syncs through to Thunderbird correctly. I can also edit any entry on Thunderbird created on an Apple device and the changes go through to all my devices. It seems that the format used when creating a new entry in Thunderbird is creating a problem in the syncing process between my iCloud account and the desktop app. Any ideas?

TB v115.8.0 (64-bit) Closed the app and went to dinner Came back and opened the app. All the tasks are GONE!!!

I know TB keeps everything in text files, so I found the "calendar-data" folder and opened some files using NOTEPAD.EXE to find keywords I know represent my tasks. Sure enough, the data is there in the sqlite files.

What's the secret code that simply decides to not open those files and populate my task window?

I used the "A" key on a message in my yahoo account and it did not go to any of the Yahoo archive folders. Can't find it in the trash either. Any ideas about where this message might have ended up? Thanks

Prior to about a month ago, downloading worked as expected: - click a link - the save to... dialog opened - choose the folder - the download is off and running

No more. For about the past month - click a link - wait for a long time with FF frozen - the a wheel starts rotating - after a full minute (or more) the save dialog appears.

Something has been broken in the mad-dash to push updates. It's fine for browsing, but the, you need to download. At that point you wish you were using a different browser (any other browser, in fact) since FF is the only oe that has this problem. Downloading works fine in a 8 chromium browsers that I have and in the 5 FF clones (like Waterfox)

It's just FF that's broken. I can no longer afford to set it as default because of this. The others are not perfect (WF won't activate Pocket, foe example) but downloading promptly is critical.

I'm about the 100th person to have this problem, so I have spent the better part of two days looking at all the threads and possible fixes. Like all the others, with no warning, my TBird stopped being able to send messages through Spectrum. It did NOT start immediately after I updated TBird to 115.9.0 (in March) but just three days ago. I have three roadrunner addresses in TBird, and one other one associated with a website I have. All have the same problem. My phone and my iPad send messages just fine.

I tried all the fixes that worked for some. They didn't work for me; I continued to get various, inconsistent Send Message Errors. I have come back to the recommended Spectrum setup for the outgoing SMTP server: mail.twc.com, Security is STARTTLS, Port 587, Authentication is Normal Password, my username is my email address. Of course the problem is not fixed.

What DID work was putting TBird in Troubleshooting mode, using the Spectrum setup above. While that is adequate, I would much rather find out what is wrong. I have Matt's 10/7/23 11:56 AM answer to someone, asking for the Troubleshooting Information. I will be glad to supply that but I need an answer to this message in order to do that. Thanks! Demaris

Hello,

I need your help because i can't find solution to problem. On my macbooks air m1 i experience a very annoying thing: Often while i'm scrolling on websites smooth scroll animation get choppy/sluggish for few moments and lagging. It's like animation is FPS dropping during the scroll. I tried lot of things on both device:

- tried without extensions - created new profiles - use without syncing data - disabling hardware acceleration (gets worst) - disable smooth scroll in settings (get worst) - completely remove firefox with AppCleaner and reinstall it - Reinstall macOS and just install firefox alone. I tried latest Ventura and Sonoma

I don't have clue why this happening but ruin user experience very bad. With Safari everything is fine and smooth. On my wife's device (macbook air m3) have same issue.

Do you have any idea how can i fix it?

I've got a Fastmail account, and have set up CardDav according to Fastmail's guide to get set up with Thunderbird.

Once my contacts synced, I was unable to see my contact lists in the Thunderbird contacts sidebar, nor can I add a list (the button is greyed out). Is this a known issue? Is it Fastmail specific, or a CardDav thing?

Running macOS 14.3, Thunderbird 115.9.0

When encountering a problem with a new release and wanting to downgrade back to an older (working) version - especially if some plugin I depend on hasn't been updated yet. The current version is well marked, but it would be helpful if the older versions had a subject line like "Release 115.x.x (github commit id)" so we can do better than walk back one release at a time. All flatpak examples for rollback show meaningful subject lines, but Thunderbird and other flatpaks I actually use don't seem to.

I always want the address bar suggestions to start with my bookmarks. Is there a way to control the results? I remember there was something in about:config previously.

Hi!

I presumed that the settings for copies to self when sending works for both replies and forwards, but I just discovered that it only works for replies. That is NOT satisfactory, and not logical - if you ask me.

I think it worked until about 2 years ago, when Thunderbird was seriously damaged by "updates", and has not yet recovered fully...

I have attached an anonymized screenshot of the "Place a copy in" settings. The sending email address is behind 3 of the erased areas. Only "Bcc these" is different.

Any solution would be appreciated. Thank you.

I have an email account with IONOS and my wife has an account. We have had these accounts for several years. Recently my wife can not send email. We are configured the same and I do not have a problem. Server: smtp.ionos.com Port: 587 (tried others at IONOS support request) Security STARTTLS Authentication: Normal password. When she tries to send or forward with a simple text (one letter or larger, it does not seem to matter). She gets the following reply: "Sending of the message failed. An error occurred while sending mail. The mail server responded: Transaction failed Reject due to policy restrictions. For explanation visit https://www.ionos.com/help/index.php?id=2425&ip=198.177.53.191&c=hd&r=0MQ4Bx-1rqmFh0x4l-00ErW3. Please check the message and try again." When trying to go to that web page, it does not exist. I have gone to IONOS support and we have both looked at the configuration and can see no differences between my set-up and hers. I have deleted all email address from her machine and reloaded Thunderbird (115.9.0), restarted her machine and added back her email. Same results, she can receive but not send. If she uses her phone, it works, and if you go to the IONOS web site and use there service it works. I'm at my wits end and can not figure it out. I have also opened an incident with the IONOS Postmaster, which I think is their second level support. Please help.

When commenting on 9gag, the blue "post" button disappears. If I choose "Desktop sight", the entire page reformats and becomes different and I lose all of my posting information.

Hello, I use Thunderbird portable. I imported as Imap an existing account at Infomaniak.com but all the personal folders and subfolders were missing. No problem, just right-click on the account and choose "subscribe" ("s'abonner" in French), ticking all the proposed folders. So in IMAP it works, but if you set the account as Pop3, the "subscribe" function doesn't appear. I need Pop3 for an account to be imported into Thunderbird. How can I do this ?

Thanks for your help !

Give that I use TB as my desktop client to access my nyu.edu email (provided by google), and that recently I updated my password as periodically requested by nyu admin When I try to access nyu email a pop up screen come up asking to authenticate with imap.gmail.com. I click next and get a 403 Access Forbidden error (Authentication failure while connecting to server imap.gmail.com.)

Solutions I have tried: 1. Clear cookies, history and cache on browsers and TB; 2. Changed default browsers (Ffox, Ch, Edge); 3. Deleted account in TB and created it again using instructions here https://www.nyu.edu/servicelink/KB0016473 4. Accessed my nyu email on browser to check user name and password. It works. I can access the email.

Nothing seems to work. Still get 403 error. As a result I am unable to authenticate and hence use the email account in TB.

I would like to have a unified calendar that when an event is added to my gmail or outlook calendar it gets copied to the unified calendar.

Is that possible?

I use the mobile version of Mozilla firefox and it choose to "remove" the open in other app feature for certain apps.

If I open youtube.com mozilla would ask to "open in other app" as an option instead of just opening it in the browser, youtube, twitter/X, reddit, etc. are fine, but for certain apps such as Pixiv and Patreon the option just dissapeared entirely, not even in the tripple dots at the bottom right does this option appear, can anyone help?
