I have 2 email accounts on TB, one is a hotmail account and one is an msn account. MSN account works fine. Hotmail account on my iphone works fine both sending and receiving messages. On Thunderbird my hotmail account receives messages but if I try to "reply" to a message or if I try to send a new message using the hotmail account I receive the following message. When I checked my version it says I'm using Mozilla/5.0 Windows NT10.0 WOW 64, rv: 52.0 gecko/20100101 Thunderbird/52.3.0

An error occurred while sending mail. The mail server responded: 5.2.0 STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied; Failed to process message due to a permanent exception with message Cannot submit message. 16.55847:BD0B0000, 17.43559:00000000A0000000000000000000000000000000, 20.52176:140F4D8011004010F1030000, 20.50032:140F4D8081174010F1030000, 0.35180:140F4D80, 255.23226:F1030000, 255.27962:7A000000, 255.27962:0A000000, 255.27962:0E000000, 255.31418:80030400, 16.55847:98000000, 17.43559:0000000068010000000000000000000000000000, 20.52176:140F4D801100F01F140F4D80, 20.50032:140F4D808117F01F2C000000, 0.35180:7D110000, 255.23226:00000000, 255.27962:0A000000, 255.27962:32000000, 255.17082:DC040000, 0.27745:00000000, 4.21921:DC040000, 255.27962:FA000000, 255.1494:140F4D80, 0.37692:AD000000, 0.37948:AD000000, 5.33852:00000000534D545000000000, 4.56248:DC040000, 7.40748:010000000000010B31373A44, 7.57132:00000000000000003A633962, 1.63016:32000000, 4.39640:DC040000, 8.45434:00010200C901F8B500000000000000001A010480, 5.10786:0000000031352E32302E303037372E3031373A444D35505231374D42313038323A63396231653232372D663432632D343833612D613332612D34353732333736386438306200F90F05000780, 255.1750:80030400, 255.31418:140F4D80, 0.22753:80030400, 255.21817:DC040000, 4.60547:DC040000, 0.21966:2C000000, 4.30158:DC040000 <00a4d544-836b-0fd1-cc78-480e216372c2@hotmail.com> [Hostname=DM5PR17MB1082.namprd17.prod.outlook.com].

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

I have used TB in Linux Debian for several years. Three days ago it was fine. Now suddenly when I try to get messages from my Hotmail account, I get a black window saying something to the effect that the server may be offline. (It disappears too quick to be able to quote it accurately.) But the messages are downloading OK to my smartphone (not using TB). And I have connected directly to the Microsoft Outlook server, and my Hotmail account is up to date. It seems to be a TB problem! I reset the Hotmail account password in TB as suggested on one of the TB sites, but to no avail. I also disabled my firewall, again to no effect. Please can someone help? (Incidentally, when reseting my Password, I stupidly failed to set the option to record it in the TB Password Manager, so it no longer appears there. I would be grateful also to know if the pw. can be added retrospectively to the PW Manager in TB, and if so how it is done.) Tom.

I have noticed a bug with how the Firefox icon appears when launched in the Windows 11 taskbar when the never group option is enabled. When Firefox is launched and is the only application open in the taskbar, there is no label present next to the icon like other programs have when launched. There is the little line underneath the icon though indicating it is launched but that is it. As soon as I open another application though, the label will also appear for Firefox. This is only a minor annoyance but is definitely as bug at least for me and should be pretty easy to fix. I will attach screenshots of the behavior. In the first screenshot, you can see that Firefox is open but has no Text label like it is supposed to. The second screenshot is as soon as I open a second application.

I am on Windows 11 Home 23H2 Build 22631.2792 Windows Feature Experience Pack 1000.22681.1000.0 Firefox Version: 120.0.1

Hello,

After upgrading my Thunderbird install to version 60.2.1 on my Xubuntu 18.04 machine, I cannot access my mail anymore, because there seems to be a problem with passwords.

Symptoms:

- When starting Thunderbird, I get an "Enter your password" box for each of my accounts even though I had my passwords saved.

- When I go to Preferences -> Security -> Passwords -> Saved Passwords, the list is empty.

- When I try to enter a password and save it, it does not actually get saved and Thunderbird will ask again soon after.

- The following line is logged to console a whole bunch of times:

JavaScript error: jar:file:///usr/lib/thunderbird/omni.ja!/components/crypto-SDR.js, line 179: NS_ERROR_FAILURE: Couldn't decrypt string

Other findings:

- Downgrading Thunderbird to 52.7.0 fixes the problem. The old saved passwords just reappear again and Thunderbird has no problem logging in.

- Starting Thunderbird 60.2.1 on a Windows 10 box with exactly the same profile folder works fine. It can read the passwords and access my mail accounts.

Can you please tell me what to do to fix this, so I don't need to keep using an old version of Thunderbird just to access my mail?

Thanks,

Dear reciever. After years of using TB and what we do think is a productive mail-tool that works for the benefits we are looking for has worked. However, the last 115- constantly freezing and shuts down. This is very annoying. It freezes at some folders from the main email-client- as we have deleted older folders integrated with this. But the problems remains. . We have done everything in our knowledge of the program but still no approvement. . At this point we are using Outlook..would be grateful to have some answers and possible sollutions for this issue. . Thanks in advance and keep up the great work U are doing. :-)

It has been one year, and you still have not fixed the multiselect functionality that was ruined with your Supernova "update" (which is worse in almost all aspects btw). Can you at least tell us WHEN you plan to release the fix since you locked the comments to block the countless negative ones? Is it so hard for your UX team to understand that removing multiselect functionality is like removing Ctrl+C, and Ctrl+V and set the correct priority???

Hello, I've been using Thunderbird since it first came out may years ago and have been a satisfied user. Sometime in the past year, after one of the Thunderbird updates, Thunderbird became EXTERMELY slow to open. It takes over a minute. I have looked for solutions here for the past year...no luck (I've read through most all of them here, that have to do with slowness of Thunderbird opening, as well as on Reddit). I've tried basic troubleshooting e.g. clearing Thunderbird cache, increasing cache to huge size. I've seen references to the slowness being related to "multiple calendars". I don't use calendars on Thunnderbird and went as far as to delete/disable the default one that was there. Still no improvement. I know its a Thunderbird specific problem since:

a. I don't have this slowness opening any other program on my Mac (opening it or using it) b. I don't have a problem with performance of Thunderbird once it finally opens c. It all started in 2022 immediately after one of the Thunderbird updates.

I am on: Mac Air M1, Ventura 13.2, 16 GB Ram Thunderbird 102.14.0 (64-bit)

I hate to ditch Thunderbird after using it all these years and being a very early user since it came out, but I am at wits end. Any help is appreciated. Thanks for any help in advance!

It used to be a rare occurence, but now every single time I close TB and shortly thereafter, during the same session, I try to re-launch tb I have to call up Task Mgr and kill thunderbird.exe. It is an annoyance which I would like to get rid of. Any suggestions? Thanks!

Dear Support,

suddenly my INBOX file has a size of 480GB - the mails in all my IMAP folders online is less than 4GB.

How can that happen?

Is there a fix or should I just re-create the account?

Best wishes, Johannes

I have not been able to connect to www.paperbackswap.com for 2 days using Firefox. I get this message - The page isn’t redirecting properly-An error occurred during a connection to www.paperbackswap.com. This problem can sometimes be caused by disabling or refusing to accept cookies. This is a persistent problem happening every few days. I have sent messages before to PBS and Firefox with no response. I have cleared cookies and added PBS to Firefox as a site to always accept cookies. I can access the site using Chrome but I would prefer Firefox. Is there anything that can be done?

I'm not familiar with how all this works, but excited to learn! I was going to wait to get the mobile client for Thunderbird once they launched the "Thunderbird" version, but didn't want to wait anymore and got K9 Mail. 😅 After setting up my account, none of my previous emails came through. Is this the expected behavior? I went through all the K9 docs and didn't see a mention of this. I've also gone into the settings and used the fetch mail option and tried to refresh the feed multiple times but it just spins forever. Have closed and reopened the app multiple times. It's been over a day and I only have about 2 weeks worth of email to fetch so I figured it can't take that long to pull everything in, right? I even got an email since setting up the account but that one didn't come through either. So confused 😵‍💫

1. Web pages load in gibberish, they aren't legible. 2. Web pages load with neon green blocks. 3. Firefox isn't allowing me to download an entirely new download.

I understand the gibberish could be a font problem but when I use right click for inspection options, I can't find any font info anywhere. Even if I could, what would I do then? Green blocks, have no idea. I used to use Firefox and have just now started again but would prefer a brand clean copy. Mozilla isn't giving me that option. Thanks.

I have a very good PC (5800X3D, 7900XT, 32GB DDR4 3600), but Firefox (either the normal, canary and nightly version) can't play smoothly any 4K video (like the Borderlands trailer: https://www.youtube.com/watch?v=lU_NKNZljoQ ). 1440 and lower resolutions are fine, as are 4K videos on Chrome and Edge. FWIW, my CPU during 4K playback is barely used (1-2%), and my GPU's video codec (VCE) is used by around a third. Disabling HW accel makes things better, as it still stutters but it's (barely) passable. I already tried creating a new profile, but still it's the same.

I updated Thunderbird to the latest version and now I have a problem that continues to remain after closing the process.

Thunderbird 115.10.0 64bit (Build ID 20240412173147) OS Windows_NT 10.0 22631

Hello,

For an unknown reason, my firefox sometimes is really slow to startup.

It can take up to 10 minutes before the webpage start to load. My hardware is not that bad. I try to use the "performance" to capture the issue : https://share.firefox.dev/3x2rgHj I don't know if there is something to see because, the tool is also slow.

It happens on 3 different computers on linux.

I try to disable all extensions and without telemetry but nothing change. I'm reporting the problem now but it's much older

If you have a idea to fix this issue please share because it's really annoying.

I say crashing - it will not open. The closest I get is that it will say 'running troubleshooter mode', and then immediately close again before I can even see the actual browser. This issue does not occur with Chrome or DuckDuckGo, so it is not an issue with a Microsoft Family account. This issue is not related to missing or corrupted redist files, as I have installed all of the latest files there. I would like to switch to Firefox, as I use it on my phone.
