I am using Beta Version 118.0b5 (64-bit) Deletions of even 5 emails takes several seconds where the screen dims and I get the timing circle, saying Thunderbird is not Responding. If I am deleting an entire Junk folder, it takes several minutes. This never happened in the Release versions. Is this something the Beta team might be working on?

After transferring my email to a new computer with Windows 11, I encountered a printing error when trying to print a received message. When attempting to print a message that should fit on a single page, the email program prints many more pages, leaving about 80% of each page blank where the text should be. I have attached an example in the sent attachments where one printed page is turned into multiple printed pages. I've tried various methods such as changing the text encoding and scaling, but nothing seems to help. Please assist.

Hello,

since Saturday, 9th Sept. 2023, ca. 14:00 GMT my Thunderbirds are producing error messages.

I have added four different outlook.com email-accounts, each with IMAP+TLS+OAuth2 as incoming server and SMTP+STARTTLS+OAuth2 as outgoing server configuration. The error messages are only regarding these outlook.com-accounts. A gmail.com-account with the same settings is not affected.

I encounter constantly popups with the following error messages: - "...user ist authenticated but not connected" - "the server is offline" - something like "authentification error while connecting to server outlook.office365.com"

Also the Page where i should enter the password to create the OAuth-Token keeps opening and closing before it could load completely.

The most astounding thing is, the synchroniziation seems to work nonetheless. It's just the messages that annoy me.

Here is an entry from the Thunderbird error-log: "mailnews.oauth: Error response from the authorization server: invalid_grant; AADSTS50196: The server terminated an operation because it encountered a client request loop. Please contact your app vendor. (...) https://login.microsoftonline.com/error?code=50196"

The problem occured more or less suddenly on 3 different PCs: - Two Windows 10 Pro 22H2 machines with the Thunderbird versions 115.2.0 and 115.2.1 - A Fedora Linux machine where Thunderbird 115.2.0 is installed via Flatpak

What I already tried with no success: - De- and reinstalling Thunderbird with deleting _all_ user Data - Upgrading Thunderbird from 115.2.0 to 115.2.1 - Revoking the access for the Thunderbird-app in the Microsoft.com account OAuth-Settings and granting it again when creating a new token by logging in with Thunderbird

What my inquiry has delivered yet: - Thunderbird seems to have problems to remember the OAuth-Tokens. When I look in the privacy settings at the saved passwords I can see that the passwort seems to change constantly. In contrast, the Google-gmail.com-account keeps the same passwort. - It seems to be especially triggered by closing thunderbird and opening it again shortly afterwards, though it does happen without doing so too. - The error messages pop up and the password-page opens mostly when I click on a folder (presumably because Thunderbird is trying to sync it then)

My accounts seem to be fine. I have no problems accessing them with OAuth2 via K-9 Mail on my Android 13 phone. I can also log in via the Web Interface.

Thank You for your Time!

This is a recurring problem. I have just been on to Vodafone who have tweaked my router as my speeds, download and upload, were very erratic, and upload speed often zero so connections failed. Sometimes my phone speeds were similar but not always. The Speedtest by Oopla desktop app also showed erratic results but often when they were OK the web-based test on Firefox was much worse, with upload speed zero. When I started this Firefox showed upload speed zero. Now Firefox shows upload 18Mbps. This variability keeps happening and is driving me spare, as even emails often fail to go through - I use Thunderbird. I shall see how things go tomorrow and tell you how it is going.

Updated yesterday to the latest version of Supernova 115.2.3. It added two new Local Folders, both Bin and neither added by me. I deleted ... without additional issues that I am aware of.

How stable is this new release ... should I revert to pre 115?

On a site with a menu along the top the rightmost item is missing, and only in Firefox, not Chrome or Edge. It happens on various pages with the same menu setup. I cleared cookies & cache, turned off extensions, no luck. See attached image. What could the problem be ?

i'm working on it from three hours and have read many solution on firefox support or others website, no one works...

I'm using Android 13 and Firefox is updated to the latest update. When I Google something and select an image, Firefox freezes and I either have to reload the page and the image will load or I have to close & reopen the app and switch to the Images tab. This is on the main Google search page. Images selected in the Google Images tab work as expected.

I have the problem that Firefox does not correctly recognize when I want to scroll up on a web page. This often causes me to accidentally refresh the page. Usually this should only happen when I'm already at the top of the website and then swipe down again and not in the middle of the website. I have even tried Firefox Nightly and Klar, but the issue occurs with every browser. Is there perhaps some trick or hidden setting that causes the browser to scroll reasonably again instead of constantly refreshing the website?

Hi All, Since update of Thunderbird to version 115.2.3 (64-bit), I keep getting 2 instances of Thunderbird that vie with each other to retrieve IMAP messages. I keep getting error messages until I close one of the 2 instances (Thunderbird windows). I found a workaround. If I click "Help | Troubleshooting information" and press "Clear startup cache…", then "Restart", Thunderbird restarts normally with only one instance. But this is only temporary. It happens only once after I have cleared the startup cache and restarted Thunderbird. When I restart Thunderbird later, it systematically launches with 2 instances. Thank you for any more permanent solution.

Hi, I have had TB working for a decade without a (serious) problem, now it suddenly stopped working and slowed down creating a lot of problem to the whole PC. It wasn't useful to reinstall or moving mail from the inbox or rebuild the index, so now I've decided to purge it all and uninstalled it, then I need to know exactly all the remaining folder and file to delete, as well as registry keys involved by any modification. Other info: Win 10 pro 22H2 completely updated, no particular AV, rather firewall on the router plus Defender on the PC (intel 7 9gen + 16GB ram). I have 4 gmail accounts, 1 Italian free mail and 1 registered mail, that works very well from the relevant web sites. Just for the sake of curiosity, what kind of problem it could be? Most important of all: does such problem can repeat starting from scratch? I don't want to face again such kind of mess. Thank you for your time and consideration Best regards Vincenzo

In thundertbird 102.11.0 (32-bit). unread messages remain unread aftrer selecting the message. I have to opeen the message in order to mark it read. This is different from what happened beforew. just selceting the message would make it Read. This is slow as I dont always need to open messages In Settings > General, Reading and Display, Automatically mark messages as Read ius checked, and Immediately on Display

I have a mail provider that has a funny folder hierarchy like inbox

   trash
   sent
   ...

Basically, all folders are under "inbox".

• • Before version 115.2.3**, smart folders were handling that properly.

Now, when I add that "inbox" in the "inbox" smart folder search, it appears for a few seconds there, then disappears until I actualize" again the inbox smart folder. Sometimes thunderbird crashes/

I use Gmail and TB is continuously downloading over and over.

Why? How do I stop this from making the program unresponsive for 20-30 minutes throughout the day?

Everything was working fine on Firefox up until a couple weeks ago when my searches started lagging.

What happens is - if I type a search into the main URL/search bar on the browser, it loads just fine. But if I type a 2nd search into a website search bar, such as on google.com, there is about a 12 second delay between me hitting enter and the page actually starting to load. The page freezes during this time and is unable to be interacted with. This issue does not happen in any other browsers outside of Firefox.

Things I've tried so far: Troubleshoot mode/safe mode, clearing cookies and cache, uninstalling and re-installing Firefox

Nothing has helped... wondering if this was caused by an update?

I am a POP user using Thunderbird Version 115.2.3. I retrieve the mail headers first, then when I click on a message to see the contents of the actual message Thunderbird skips to the next message. The message I had wanted to read now becomes the previous message. I then have to go back and click on the message to see its contents. Please correct.

Hello, The latest version of Thunderbird is now automatically spamming many of my emails that are not spam. When I unspam them those emails are being deleted for ever and I can't read them. The systems message indicates they are being rerturned to Inbox, but they are being permanently deleted instead. How can I stop this? Thankyou for your attention. Stuart Amyes

Having used Thunderbird for some time, I installed it on a new PC, and found that virtually all my emails on a particular account seem to have been deleted, despite the app being set up to retain them. I checked on the webmail (BT) and they have gone. The account is set up as IMAP - as is another account on the same server, which seems OK. BT won't engage with me on this as they "don't support third party apps" I assume that 3 years worth of important client history is gone for ever? Can anyone suggest what I did wrong, or is this a software failure?
