I've been using Thunderbird for many years with no problem. I'm now on v. 115.4.2 (64-bit). Suddenly, I can no longer send email. This is the message I get:

Sending of the message failed. An error occurred while sending mail. The mail server responded: <sy777@maine.rr.com> sender rejected. The email address you are sending as must match the email address you used to auth. Please check your SMTP settings. AUP#Out-1500. Please verify that your email address is correct in your account settings and try again.

I contacted Spectrum and received their recommended settings. The only difference I have is that my Authentication is set to NONE and theirs to YES OR CHECKED

My incoming email works fine.

Please help!

Hi. First, I have more tech problems than I can shake a stick at and I m dealing with concussion and screens (monitors, cell phone, etc) aggravates and I don't track as well online as usual, so I'm asking for help sooner than I would hoping y'all can break it down very smply for me. Thanks for reading.

Thunderbird v.59.2 on Windows Vista desktop. Yup, Vista :-) Cable provider died, so years of emails to addresses using isp-provided email addresses are in Thunderbird but can't use emails.

In short term got TMobile 5G wireless and it is hideous, beware! For now I use my cell as hotspot to get on internet on old desktop.

I'll list what I've tried in a sec, but here's my ultimate goal: I want to get AT&T fiber installed and hooked up on new desktop (Windows 11) and install latest thnder bird there and bring over old files. Before installing at&t I have to formally cancel with former cable provider (it's in an odd limbo). I've assumed it's better to cull all email addresses related to those email accounts before severing all ties.

What I tried: Followed this thread https://support.mozilla.org/en-US/questions/1255223

I can't upgrade to v60 with Vista. I modified advanced config and added strict config Boolean setting and set to false and added check compatibility 59.2 setting and set to false.

The email crawler add on still gives me not compatible error. I restarted Thunderbird and that didn't help, unfortunately.

What can I do?

Again, my two main concerns are 1) harvest email address on my dead email accounts so I can send notifications of my new email addresses and 2) prepare to move all Thunderbird stuff to new desktop once I have working wireless internet to facilitate.

Thank you for your patience with my explanation and any help you can provide.

Hello, While the display size is correct on my MacBook Pro 2021 screen is OK, it is huge and unusable on my second monitor (see images). My layout.css.devPixelsPerPx is set at 2.5. If I set it at default (-1), the external monitor display is OK, but the internal monitor is so small that it is unreadable (to the extend that it was actually hard to figure out how to revert back to so I moved the window to the external monitor). This is a bug. There should be a setting per monitor or the default should follow the System Preferences setting for all monitors.

Please fix this quickly!

Thank you, Alain Damlamian p.s.: I tried to upload two pdf images but they were refused (why only accept jpg ?)

I have used Thunderbird for more than 15 years and have always liked the way it works and promote it to anyone needing an email client, but the latest version 115 Super Nova is terrible. I don't like the font or anything in the update. Now I just found a new problem. Since last update messages show all previous messages from same sender with current message at the bottom of list. I have looked for a way to change this but have not found anything. It used to work so good and now it sucks.

Thunderbird layout - how do i enlarge the classic view current message pane window? it's too short/compressed, and i can only drag it up a little, then it stops. In the prior TB versions, I only saw the last 3 or 4 messages in the upper message list portion of the classic view layout. Now I'm seeing almost 10 messages in my messages list. Meanwhile, the actual current message viewing pane is now horizontally compressed so that the ratio of message list to message view is closer to 40% message list, 60% actual message text plus the header info. I have tried click and drag the upper border of the current message being viewed, towards the top of the screen, but it stops, and still shows me 10 most recent messages in my list, which is really useless. I only need to see the last 3 or 4. The rest of the viewing pane should be more of the text area of the current message being viewed. Is there a "config editor" tweak to reduce the messages list to 3 or 4 messages, and increase the actual current message viewing area? Or some other fix for this?

I upgraded to 115.3.1 from 102.15.1 this week. I do not understand the large increase in version number, but I have not done any searches. I have a number of complains with this new version.

1) I want to move one message to a Local Folder, and I get the message at the bottom "nn messages moved from Inbox to Tr.ash". The one message I wanted to move remains in the Inbox, and I have to move it again. When I try to move them again, the folder displayed is NOT the one into which I had just tried to save. I have no idea if any messages were moved from Inbox to Trash, and I have no idea how I would find them.

2) The font size in the window is smaller than it was with 102, and there is blank space on the right. Is there a way to increase the font size?

3) I read one mail message and I process it (delete it or save it in a Local Folder). Most of the time, the next message in the Inbox is opened. But sometimes the window advances to a message further down in the Inbox, and I then have to go back into the Inbox to access then next message I was planning on reading.

why do you stalk and bother the users? i do not want to update! without warning you alter things i do not want you to alter. you take things out so people have to use risky 3rd party addons.

Since the last FF update (115.5esr, Windows 8.1 Pro) I keep getting the following error message when I try to access one particular website:

The page isn’t redirecting properly An error occurred during a connection to www.doordash.com.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

I have tried virtually all the solutions suggested online. I have cleared my cache, deleted cookies and site data, and I have tried to access the site using Troubleshooting mode, all to no avail. I contacted support for the particular website and they have no difficulty accessing the site with FF.

I can access the site in question with the Chrome browser, so the issue would appear to lie with Mozilla. I use this particular site frequently and would much prefer to continue to access it using it with FF, as I have done for over a year. I just installed Chrome on my Windows 8.1 Pro PC solely for the purposes of accessing this one website.

Help in resolving this issue would be greatly appreciated.

My apologies if I am being a numpty, but I have been using Firefox for many years without issue, and recently (possibly after an update, but I cannot be certain), it has started to randomly freeze. I am running Ubuntu 22.04, and Firefox 119.0. I have demonstrated to myself that if I open a web page with links (but not always), and click on the link, I may still scroll up and down the page, but the mouse cursor never seemed to recognise the hotlink, and doesn't jump to it. The links will work on Chromium. I initially tried resetting the browser, thereby losing all my open pages, but that didn't work. That also removed all extensions ("all" two of them) and that didn't work. Firefox is now pretty much unusable. Any help to resolve this would be appreciated, as I cannot find any solutions online, and it seems I am not alone with this issue! Many thanks,

Hi.

After upgrading to TB 115, I have a little problem. I have my mail lists sorted by date ascending. Before, when starting TB, it always showed the lists at the very bottom. With 115, it does not. I have to press <ctrl> <end> in almost every subfolder to get to the new mails. This remains in effect during the session, but on restart, the same thing. Is there a configuration thing I have overlooked?

Hello,

I am getting a frequent freeze in the Android app and then shortly after a crash. Info: - happens on FF, FF Beta, and FF Nightly,and reinstall/phone reset didn't fix. - Samsung Galaxy SM-G965U running Android 10. - every error starts with java.lang.OutofMemoryError. - it never happens just on startup, just on auto fill, or some of the similar crash reports I've seen around here. - it does appear to be site-specific, but sometimes the site works and sometimes it does not: if I close the last tab after a crash, it will usually work for awhile. - Sync and disabling Add-ons doesnt fix it, although perhaps its worse with uBlock Origin enabled (not conclusively)

Thanks for any suggestions.

For the past few weeks, I've been having a problem with Thunderbird's buttons. When I have an email open, I can usually click the "delete" or "junk" button to send it where it needs to go, and the next email will automatically appear. But recently, those buttons only work once: if I click "delete" or "junk" on the second email that comes up, nothing happens. I have to close that email and delete or junk it from the Inbox. Am I the only person having this problem? I tried deleting the Trash files in the profile, but that didn't help.

I have been receiving the following error code 'PR_END_OF_FILE_ERROR' on several website on my Firefox browser. Sometime, not all the time, I get the same error message while trying to use YouTube, while other times the site loads but says that I am offline and no internet connection. I have done all of the fixes that they say to use online and nothing seems to work. YouTube will occasionally work but none of the thumbnails will show up. Then there are other site that work fine.

Hello,

I have a problem retrieving my favorites/bookmarks. I changed computers (all of them, even the hard drives).

I would like to recover my favorites/bookmarks but cannot do so because I am asked to look for them in folders that I no longer have, because they are on the old computer.

Does Firefox not save any information about my favorites/bookmarks? Have I lost them all? Do I have to redo my whole life?

Sincerely, Shinsengumy

Ever since I decided to have a password to use thunderbird I do not receive any messages for alan.green27@ntlworld.com even when I am told that a code has been sent there. Why are they being blocked? I do get messages for leananger27@gmail.com which is not the lead e-mail.

Hello,

I'm new to Thunderbird and I was checking out the features of the Thunderbird app on my Windows 11 PC. I'd like to understand somethings with the passwords feature.

I see that the password of the added email account in the 'Saved Password' dialog box at Settings > Privacy & Security > Passwords, when shown is displayed as a long coded line, rather than the actual account's password.

Q1. Could you please let me know that is this done as a format to encode the original password?

It seems the app itself automatically does this, as I checked with this 2 times, by deleting the password and again approving the 2FA login credential when re=validating my email account.

Q2. I would also like to know that what is the real point of not displaying the actual password to the user when the 'Show Passwords' button is clicked?

Q3. Can you please let me know if there's some reason as to not having it display as masked characters representing the actual email account's password which authenticates with the email provider server, like many of the other email applications have it?
