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!

ONCE AGAIN, I am having Hotmail issues through Firefox, and ONLY through Firefox!!! I had to go to PALE MOON AGAIN to use Hotmail. This is getting REALLY irritating. I can go to ANY OTHER website through Firefox with no issue, but Hotmaill? Oh no, of course not. Your damn browser refuses to cooperate and Hotmail just sits there for the past TWENTY-FOUR HOURS with a waiting symbol and stalls out, refusing to do ANYTHING to refresh the page, and when I try and open an email, Hotmail says, "We're sorry, we can't display that message right now." But when I use Pale Moon, NO PROBLEMS WHATSOEVER!!!! FIx your damn browser to work with Hotmail CORRECTLY this is YOUR problem!!! Since it works FINE through Pale Moon the problem is OBVIOUSLY with YOU!!! I am so sick and tired of YOUR BROWSER stalling out and causing issues ALL THE TIME! DO SOMETHING!!!

I upgraded to version 115.2.2 (64 bits), on a Windows 10 OS.

I used to be able to reduce the pane of the message list, so that I could expand the contents of a selected message. But now it has a lower limit, where I cannot push the line up further.

Attached is an image showing the line of concern. I could drag it down, but no further up. How could I change this behavior?

Thanks!

Using Thunderbird 102.4.1 - have not upgraded for a few days and program was working fine. Switched on today and inbox was rebuilt - and then all the messages are there but the From / To / CC fields are all blank on the message pane. When I reply to a message all the information is available. The From/To/CC is also visible on the summary pane. Same issue on all messages in every folder. Tried to restart in troubleshooting mode with addons disabled but made no difference. I have Header Tools Lite addon - disabled that but does not fix the issue. On Windows 11 and everything was working fine until this morning.

In Thunderbird 115 (Supernova) is there a way to configure the Message list view so that it has grid lines, or "zebra striping"? I find it easier visually to look at.

Thanks!

TB working fine, then next day opens up as Blank screen and a setup tab Profile shows to be still there as do mail folders .... so need to recreate profile.

Created a new Profile I copied over the folders:

 IMAPmail
 Mail

and the following files

 key3.db
 logins.json
 cert8.db

and all of the pref.js files (1 through to 141)

The profile folder does show new profile active ( as per this pic https://flic.kr/p/2pjRyRz)

I created the 2 IMAP account login details, I now have access to the inbox for 2 IMAP account, but I do not have any the filed mail (local folders) how do I get these back. This is an important item for me as many years of filed emails.

I have Win 10. Sometimes, when people send me emails they go right into the trash folder at the very top.

I have so many duplicate folders I dunno what to do

I will add a ss of what it looks like

I just upgraded to version 102.1.2 and almost all is working fine. However, when I go to my Newsgroups I now need to enter Username and Password.

I have checked the "Use Password Manger to remember this password." It works for that time but then a few minutes later I need to do it all over again!!!

Then when I try to go to Tools>Options>Privacy & Security>Passwords the "Options" link does NOT exist!!!

In all the years of using Thunderbird this has never happened before on a Upgrade to a new version.

Is there a fix for this in another update or is there something I am missing??

Thanks,

Les

When I send a webpage (here's the code for it) -  :javascript:location.href=%27mailto:?SUBJECT=%27+document.title+%27&BODY=%27+escape(location.href); I call it "Send Link" - it does not show up in my sent folder. It used to work but no more for some reason. I'm aware of Tools, Acct Setting, Copies & Folders, Place a copy in sent folder or place in "Other". This does not help me. All other emails go into the Sent Folder. I am perplexed. Thanks for any help. Donna

When typing comments on a web blog, after the spacebar is used, the first letter of the next word eliminates the previously typed space. So what I end up with is all words in a sentence running together. Tried other browsers and they work fine. Changed keyboard as well no joy. Typing is normal in applications like adobe, word, etc..... Only happens during Firefox use......... Uninstalled and reinstalled Firefox, also no help..... How do I fix ?

I have just installed Thunderbird 91.11.0 (64-Bit) on Kubuntu 22.04 LTS.

I would like to have all of my message folders have the following columns:

Attachments, Subject, Received, Size

I can make the change easily enough, but they keep reverting to the default columns. This happens whenever I change folders and return. Sometimes I can actually *see* them change. For example, if I set my desired columns for my Inbox, and then change to a different folder and back to Inbox, I'll see my desired columns - and then they'll change back to the defaults a few seconds later.

I would actually like to apply these same settings to all of my folders. To do that, I have used "Apply columns to..." and selected "Folder and its children" and selected the account at the top of the folder list. I have also tried just applying the view to Inbox.

None of this works. It insists on using the default column list, which I do not want. Ever.

I'll note that this is a new install of both Kubuntu and Thunderbird. This machine suffered major file corruption a couple of days ago from a power loss during an upgrade. To recover, I clean installed everything from scratch into a newly formatted disk.

This machine was previously running Ubuntu 20.04 LTS with an unknown version of Thunderbird (since the machine crashed, I lost the version information). That install did not have this problem.

I would appreciate any suggestions to make a permanent change to the column layout.

I've been running TB38/linux for a long time and have many extensions and .css entries. In order to comply with gmail's upcoming OAuth2 requirement, I just installed TB91 and copied over the contents of my TB38 profile into the newly-created profile.

Imagine my disgust to find that none of my .css entries (mostly involving fonts not dealt with in the preferences) and most of my extensions and colors are inoperative. I've been tweaking TB since it was Netscape .9 and appearance and LEGIBILITY (Arial bold) is really important for something that I use for many hours per day. Quite frankly, I hate this new version. If I have to I will use it in order to avoid losing my SORTED email going back to 1995, but I'll do it resentfully.

It has been my experience that with each update I lose something of value to me -- hence my stop at V38. What is the oldest version of Thunderbird/linux that will satisfy gmail's OAuth2 requirement?

I'm sure I'm not the only one wondering...

I've used gmail (with multiple email accounts) on Firefox for many, many years. I switch back and forth between my email accounts daily.

In the past few weeks, though, when I try to switch from my primary account to the others, it just defaults back to the primary. I've purged the cache, I've signed out and signed in. This does not happen on Chrome, just Firefox, which is why I've brought it here.

If I change the URL of the mailbox

https://mail.google.com/mail/u/0/#inbox

to

https://mail.google.com/mail/u/1/#inbox

It will take me to another mailbox. I can then change that number to get to the others. But it shouldn't be that way. So ... what is going on? How do I fix it?

Prior to FF97 a simply setting to "false" the about:config, print.tab_modal.enabled setting allowed FF to always use the system dialog box when printing. However, in FF97, this is no longer the case. How can I set FF97 to always use the system print dialog box??

I almost always use Preview printing on my Macs to avoid multiple pages of garbage so this is fairly important to me...and it might help to save a few trees...

My thunderbird just upgraded to 115.2.2 (32-bit) - my windows is 64-bit - but I can't read the preview window or emails. Everything is in a gigantic font so I see only 2 lines at a time in both the main email edit screen and the preview screen. I tried changing it to Calibri 12 in Settings (it was Calibri 17) but that makes no difference. I also don't like that I have to go through File menu now to get messages for just one account. Is there a way to downgrade back to my old version? I guess that would be 115.2.1. Thank you!

I had an arrow on the right side of my FF Toolbar for "Other Bookmarks". Recently it went missing. I have many bookmarks under that heading, and can get to them through the Bookmarks Manager, but no arrow on the Toolbar. How can I get it back?

Hello! I have the grey/italic problem that has been reported often here as well. I tried these solutions, but they didn't help: https://support.mozilla.org/en-US/questions/1293067 https://support.mozilla.org/en-US/questions/1246828

I contacted the support of my email provider and he said that the problem is TB and not the IMAP server and I think he is right because logging in on the web the folder structure is fine and all messages are there.

so the final solutions was to reinstall TB. I did this first without deleting my user profile from the folder "roaming", but the problem persisted just the same way, and then I deleted the entire user profiles folder and the issue still exists. this means to me that this wasn't yet a clean new installation so that TB creates the folder structure completely new. To me It seems to me that TB is storing some information still on another location. Might this be?

So, how do I force TB to completely load from scratch the folder structure and it's content?

Best,

Wolfram

Hi,

I did an upgrade yesterday from 91 to 102. This morning, I get a few issues. Some email messages are blank. Some have a lot of header and content code displaying that is not related to the email I am opening but from a different email message. Some emails have no HTML content but others are fine.

On my cellular device, I am using the Bluemail app and all messages are there and are fine so it appears to be related to Thunderbird 102 upgrade.

I have used Thunderbird for years and this is an issue I have never seen? I am running an IMAP account.

Thanks,

Mike
