I've been using Thunderbird for years and have never had this problem. Since the upgrade today, after I run Thunderbird once and close it I can no longer start it up again. I have to reboot or use Task Manager to kill it in order to run it. This is on Windows 11. Please help - not an acceptable workaround for long. Optionally, how do I downgrade to previous version? I should know better than allow automatic upgrades.

Adding a couple images below, when it has started successfully it shows as one of the Apps in Task Manager. When I close it, Thunderbird drops into the Background Processes but doesn't end. I have to kill it here in order to start it again.

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.

Hello. I have a pretty big sprite image i am trying to display on my web page but mozzila wont display it. The sprite is 78016px by 1000px and im cropping it to be 736px by 1000px. Sprite is made out of a png sequence that was made in 3d software, now the thing is when i put in the non rendered verson of images(3D viewport colors) which windows labels as 8bit (maybe because of less colors) it gets displayed, but when i put the rendered version which windows labels as 32bit image it wont get displayed on Mozilla. It gets displayed on Chrome and Edge without any problems. The only difference beetween the images is that the rendered version has a transparent background behind the subject...they are the same sized sprite. I will drop the first frames of the sprite in the images section so you can get a better idea. Also all of the code and images is stored locally.

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.

1st, I'm old, cant code, tho wish I cld, so am naive and tho being online for over 20 years, just dont get any tech etc on how any of it works (damn it).

My issue, is th incompatibility across 1st O/S's, due to competition but mainly bcoz of the lack of ethics inherant in capitalism.

As my meme has; "cRapitalism - guaranteed to make a$$holes of otherwise good folks!"

But, "that's evolution fo' yo'!

Point is, th web is still a baby, so has a way to go b4 it, thus all operators and users, "evolve" to agreed bases, O/S's, layout standards for all the sites, platforms, apps, etc.

Eg1; Social media platforms? All in their own anazing ways, are fabulous.

But (yeah, an "old Luddite's" problem) skipping from 1 to another, and another, each w its great but own layout, is longterm, long-game, all up v innefficient.

So, IMCO, there needs ASAP to be a meet of both developers AND govt specialists, to begin a project to design GLOBALLY-acceptable layouts etc, for maximum user-friendliness, and other vital factors in sites' designs.

I write this on my phone, bcoz sPOOks have hackrashed every lap and desk top computer, bcoz of my REALPolitiks, so that'll do from me.

Sayin', "sameness" of all parts for online use, like the accepted "QWERTY" keyboard layout, as with Post Offices, I guess, all requiring postage stamps in the dame corner of envelopes, globally, etc, baby internet needs to gwow upsies, above the usually excellent egotrips of each web layout etc., to maximize humanity's communications systems.

Cheers.

But, maybe ending cRapitalism would improve human intelligence faster, so we dont go extinct fighting for our own egotrips to rule?

Hi, I use thunderbird ver. 115.9.0 on Garuda Linux Gnome (Arch based distro). From some time I noticed I cannot copy in app. I cannot copy text from messeges or copy text from popup window with thunderbird version. I try to change theme but it don'y 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.

HI, I'm trying to move the text to below the picture as in the screenshot of the popup (black back ground) on the non-popup pages because the mobile is not in popup, and the text is blocking the artwork as well. Is there a section to move the text outside of the picture? Thank you!

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?

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

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?

Hello. I use youtube website as music player quite often (without premium) and play my favorite list of songs. Meantime, when Google started meddling with youtube due to their new offer as youtube premium I met two most annoying issues like "are You still watching" dialog and the behaviour where youtube just cleared "repeat list" function without my consent. Both issues was resolved with java scriplets I took from community.

Now I run into third issue but not sure how to diagnose it. If Firefox is in the background, or tab with youtube has no focus the playlists stops from time to time. The moment it stops is when next video should start playing. When browsing on different tab, I can see on Youtube tab that title of the video has changed (to the next video) and even the song started (for 1-2 seconds) then video pauses and word "playing" disappears from tab (normally there should be title on tab and "playing" word under title). It is not "are You still watching" dialog issue because if I move mouse cursor on youtube tab (even without setting focus on it) the player will continue - till next song.

The issue doesn't appear if youtube tab is active. I can't use developer tools in firefox because can't debugging website when tab of the site is not active (at least I don't know how). I tried to find solution with community but with no success. I allowed youtube to play video and sound always without exception in firefox preferences but it is not the solution.

Any tips?

All of a sudden two of my aol accounts won't sign in. I get a browser screen that looks like an aol sign in window and says to enter my aol log in credentials, but the URL is something else. Clearly bogus stuff, and surely attempts at phishing credentials. One other aol account still seems to log in just fine.

I have had a few emails that did not show up in the inbox listing, so the message count at the top indicated more messages than were listed. Doing a search showed them, and by moving them from the search results to another folder, and then re-searching and moving them back, caused most of them to appear. But not all - I still have a message count of 20, but only 19 listed, see photo 1. Photo 2 shows the hidden email (from Barry Chandler). So the email is there, it's just not visible!

I have several email accounts; and they are all set up the same way on Firefox, and I have checked that that is so. But on one of the email accounts the "sent" file is missing. I have checked the "place copy in Sent..." In the subscription list "sent" does not show up for this account

Do you need more info ?

What can I do / check ?

Thanks, Dieter
