I have faced with the following bug linked to messages displaying in thread in any section of Thunderbird (i.e., Incoming messages). See the screenshot - there is just thin white stripe instead of text of the message. This bug repeats only for some random messages. Restart of Thunderbird resolves this bug temporarily.

When I use a html signature with graphics, the recipients who can not receive Html, do ot receive the grafics, obviously, but also not any other attachment like a PDF file. The same is sent but not received! in other words, our customer complain that we forgot the attachment, but we did not. If I resend without the signature, they receive the PDF file. If I reply with an attachment and have a previous signature with grafics in the feed, the attachement also disapears. The only solution is no grphics in the signature, but that is not a solution, just a quick fix. Thank you very much for your replies.

When I open firefox it opens on the "success" page it should open on my selected page Yahoo.com

this happened after I ran the "refresh firefox" option

trying to get email - got this error; How do I fix this?????????? Happening last few days.

my email: [edited] @yandex.com

Sending of password for user pizzipie did not succeed. Mail server pop.yandex.com responded: [AUTH] login failure or POP3 disabled, try later. sc=75IVcg0DLKo0_290005_

So my firefox recently started freezing while watching live streams on both youtube and kick. It'll freeze and buffer forever until I either refresh (kick) or hit the grey "live" button on youtube and the whole freezing thing repeats again after 2 minutes. Add-ons and internet speeds attached

I am using Thunderbird v 115.5.1 on a Windows 10 system. I am using an "@hotmail.com" email address. I seem to be able to receive emails just fine, but face an issue sending out emails. When I press "send", it gets stuck on "sending message" for quite a while, then I see the error message:

=

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. Try again.

=

My SMTP settings: Server Name: smtp.office365.com Port: 587 Connection Security: STARTTLS Authentication Method: OAuth2

Appreciate any help! :)

I have just switched to Thunderbird from Gmail. Have tried several times to send bulk emails but always get this message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: We have detected an unusual amount of suspicious mail originating from this address. Please try again later.. Please check the message and try again.

I have a need to send emails frequently to more than one address and this is going to be most inconvenient if it can't be fixed. Is there a setting somewhere?

Thank you.

Was just updated to version 115.5.1, and I had held off posting this question until after the update, hoping the issue might be resolved... but it's as bad as ever.

Tbird abruptly became very slow to delete/display messages; not with the last update, but a couple of updates previously. I have been in the habit of working my way up the list from the oldest to the newest, and as I hit "delete" and "up arrow" to view the next email, it's a slow, laggy process. Both emails remain highlighted for a second or two, the old email continues to display, then the deleted email drops out, and shortly the new one displays, the whole process taking a bit over two seconds... to move from one email to the next, a process that used to be nearly instantaneous. No idea exactly when that changed, but it seems to be a process that's getting worse with time.

Any ideas on what I might be able to do to get my original level of performance back? For what it's worth, this is a new machine, insanely fast compared to my older one, and Tbird is the only app where I'm encountering this kind of slowness issue. Everything else is astonishingly faster by comparison... but Tbird remains laggy and slow and I've no idea where to start looking for reasons for this. Don't even know what kind of information to post here that might be useful in diagnosing the issue - - tell me what's needed and I'll do my best to get it. Thanks in advance! I *really* don't want to change email clients after all this time!

TRYING TO OPEN A SAVING ACCOUNT WITH BANK OF MONTREAL https://www.bmo.com/main/personal/bank-accounts/ CLICK ON THIS ONE: Savings Amplifier Account AFTER CLICKING THIS WINDOW APPEARS: https://www.bmo.com/main/personal/bank-accounts/getting-started/?rg=BMO&spc=7880184&ofid=SAASTAND001&lang=en IT TELLS ME TO USE ANOTHER BROWSER LIKE Firefox..... BUT I’M USING FIREFOX. I DON’T USE ANY OTHER BROWSER. HOW CAN I SOLVE THIS ISSUE?

I am using Windows 7 and Firefox 115.5. When I close Firefox, it stalls and after a minute I get an error message saying Windows Explorer is hung up. Then if I can get an option to close the program. I have tried many ways to exit Firefox but nothing helps this. Thanks.

Firefox has crashed repeatedly when I've switched tabs to my gmail in the past ~15 minutes. It happens in "troubleshooting mode" as well. I'm running firefox on a linux computer, and my ubuntu installation and firefox are both up to date.

Here's my crash id: bp-b079d597-fb83-4a69-ab65-896370231129

On Nov28 changed to Rel 115.5.1, my thunderbird can receive messages but can not send. I am getting an error message saying that my password is in error. However when i go to Mail.aol,com my password works fine. again this just started on the 28th.

The latest updates sucks. Trouble with log -in pages, even Mozilla's own page doesn't seem to like the new cookie settings... Had to get onto tis forum through chrome of all things...

Anyone aware of fixes or some way to revert to an older release?

Hi. I'm using T-bird v 115.3.2, and since the upgrade to 115, I've been seeing weird behavior regarding opening messages vs their getting marked read.

I'm referring to actually opening the message in a new window (I do not use the preview window--it is turned off).

My usual reading behavior is to open a message, read it, then press <F> to go to the next message. In either case, most messages immediately get marked as read. However, some random messages do not get marked as read immediately--after a delay, the message gets marked as read. It seems to be related to messages from some specific senders, as opposed to random messages. For example, marketing messages from Southwest Airlines always seem to have this issue, as do the daily newsletters from "The Hustle."

What are the criteria for T-bird to think a message has been read? If it matters, I'm seeing this on mailboxes where I use IMAP access. I have not seen it occur in the mailbox where I use POP3 access, but almost all of those messages are plain text.

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.gmail.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

What can I do?
