I had already post this problem recently, but in spite of Thunderbird already had two interim point releases 102.1.1 and today's 101.1.2, this problem remains.

This situation did not occur in older versions, and I cannot use pop3 access to AOL email account with "normal password" (encrypted). For the time being, I am accessing AOL web mail using Firefox.

I tried unsuccessfully all other authentication methods, so no authentication method is working with AOL.

This is the Thunderrbird error I get when using OAuth2 authentication method:

"The server does not support the selected authentication method. Please change the 'Authentication method' in the 'Account Settings | Server settings".

It is not true, AOL does support the OAuth2 authentication method.

I have been using Thunderbird as my default email for years and have run into my share of issues. Out of nowhere, starting this morning, I am unable to send emails from Thunderbird at all. I spent about 2 hours on the phone with my service provider trying to figure it out. The unfortunate conclusion I have come to, is that unless you can fix this issue for me, I will be using Outlook going forward. Let me be clear, I HATE OUTLOOK! but I am running out of options other than to throw away the email address I have been using since about 1990.

This is the message I get when the email does not send. This particular one was to trs.ky.gov, but it doesn't matter who the recipient is, the only ones that don't get this message are those I send to myself.

Your message contains invalid characters (bare line feed characters) which the email servers at trs.ky.gov don't support. reb Office 365 julie.soard Action Required Recipient

Bare line feeds unsupported

How to Fix It It appears that your email program added invalid characters (bare line feed characters) into your message when you sent it. Try using a different email program to send your message. If the problem continues send this non-delivery report (NDR) message to your email admin for assistance.

More Info for Email Admins Status code: 550 5.6.11

This error occurs when the email program or device used to create or send an email message adds bare line feed characters into the message. When bare line feed characters are included in a message, the SMTP protocol chunking feature is required to transmit the message between email servers. Chunking uses the SMTP protocol BDAT command, but the recipient's email server doesn't support the BDAT command.

To fix the issue, the sender should send the message using an email program or device that doesn't add bare line feed characters to messages. Most modern email programs don't add bare line feed characters.

If the sender is using a device like a fax machine, printer, or scanner, it's likely an older model that doesn't support the SMTP protocol BDAT command. To fix this error, you'll need to replace the device with a newer model that supports the BDAT command. The industry standard recommendation to support SMTP chunking was published in 1998 so most devices manufactured during the last decade support this feature.

Another option is for the email admin at the recipient's domain to upgrade their email servers to servers that support the SMTP protocol BDAT command. Most modern email servers support BDAT; however, some free and older email servers don't support it.

I cannot make calls via Firefox on Facebook Messenger. In the second window that normally loads tells me that something went wrong. (in Dutch tells me "Er is iets fout gegaan" This happens on both my computers, Windows and Linux. Even when I start Firefox in troubleshoot mode it is still not working. However works absolute perfectly in Google Chrome. The problem started today by my knowledge for no apparent reason. I tested the camera in Firefox, works. I tested the microphone in Firefox, works, no problem. Also I granted Facebook permission to use the microphone and camera.

I cant connect to face book messenger i get this message: Something went wrong

Try restarting Firefox or restarting your computer. For more troubleshooting suggestions, visit our Help Center.

I have a filter to mark certain messages as read upon arrival (through Tools => Message Filters). This used to work fine until the last major upgrade of Thunderbird. Now the messages do get marked as read, but I am still getting a taskbar notification for a new message, which defeats the purpose of not being alerted to these messages.

Is there a fix or a way around this? I just need 'not to be notified about certain messages', something that used to be achieved by marking them as read automatically, but that doesn't work anymore.

Thanks for any help! Gigi

My camera was working with this browser before and now it won't work. I have got to get some documents notarized and it requires facial recognition with my camera.

Hello, in summary my scenario is written below; Earlier when someone used to call me on Facebook Messenger, I could see someone calling (the messenger call sound and interface appeared) and receive the call. However the problem now is, this whole feature is gone JUST for FIREFOX. I tried checking on Opera, Edge and Chrome, all works fine. Only on Firefox this is gone. So now I have to rely on my android device to attend this calls which is too much problematic as I mainly work on a PC. Can someone please find me a troubleshoot to this problem? Thanks in advance.

On Aug 14 2022 I was receiving email just fine via Thunderbird. As of Aug 16 2022 I am getting the error UID Fetch Failed. I saw a few similar posts but nothing resolving the receive message error. It shows the number of unread messaged on my optimum account but cannot return them to the Thunderbird Inbox

Hello,

Since the last update, I've been having an issue where after about an hour or two of using firefox (it varies), video players on some websites will stop working. I've noticed that Tumblr and TikTok's video players are affected by this. Restarting firefox fixes it, but it's very annoying to restart firefox every couple of hours, and seems like a problem.

The following things didn't fix it: clearing my cache, disabling my addons one by one, turning off hardware acceleration, trying to watch the video in a private window, or reinstalling firefox. I don't know what's left to try.

Please advise, thank you!

all other browsers work fine apart from firefox since the latest update , I have been a firefox user for 20 years and if this continues then I will have to quit using it . Tried everything i can think of and it still doesn't work

Facebook voice and video chat quit working - 8/12/22 AM using Firefox. Works fine, same computer on Chrome? When calling or accepting a call the screen goes to "Something went wrong"? Same symptom on two desktops, two laptops, and one notepad. Windows 10.

Not receiving confirmation code email. I have checked the spam folder, am checking emails on three devices and have added the Firefox email to my contacts. Have tried 6 times.

Hi There,

My email keeps getting hung up on 'checking mail server capabilities' when checking or sending emails, I have searched for this problem online however none of the solutions seem to fix the problem, having done some digging it seems that the pc invloved (running windows 10) has recently added 2 updates from microsoft released 09/08/22 and ever since then it has stopped working, has anybody else come across this?

error message: Sending of the message failed. An error occurred while sending mail. The mail server responded: See http://pobox.com/~djb/docs/smtplf.html.. Please check the message and try again.

When I use the "webmail" it goes through. There a conflict in formatting with TB and Network Solutions which just started this morning.
