I have a client that sends a weekly newsletter using a list called news, it work for a long time. now he gets a error news <> is not a valid email address because it is not of the form user@host. You must correct it before sending the email.

It works on my setup, using my email, same version of TB, different domain name but the same server. I tried rename the list to a email address news@domain.com it acts like it sends, but no one gets the email. reninstall TB on his rig, same outcome. haven't had any luck searching for an answer.

I want to be able to start a live stream in Mighty Networks - all seems to work, except the go live button is blanked out. I tried all the usual up to reinstalling firefox and generating a new userprofile in windows 11 and getting a brand new firefox version running in the new userprofile. With other browsers like chrome it just works fine.

On my latptop running windows 10 firefox does not encouter this problem.

Any suggestions are very welcome, I can of course switch browsers but would prefer to see this issue resolved.

Curious to hear if any other users encounter the same issue,

Thanks for any help provided,

Bart

When using ThunderBird to write an email message, if I delete part of the message, ThunderBird automatically places the deleted text in the Windows clipboard. Is there any way to stop this behavior?

Ever since the last update I have not been able to view messages by email address nor get a listing of messages that I can scroll down and delete one by one or en masse. Is it possible for me to go back to an earlier version?

I'm able to receive messages in Thunderbird from my hotmail account but am unable to send them. This problem started the version before 115.4.3. This use to work. I have not changed any settings. I've tried removing the account and re-adding, but that didn't fix the issue.

The error message is: Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp.office365.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

Attached are images of the servers settings I have.

Help!

I am trying to set up 3 yahoo email addresses in Thunderbird for myself and my family. I was able to set up the first one (mine) successfully using Thunderbird's email setup wizard which uses Oauth, but when I try to set up their email addresses, for some reason it redirects the Oauth login to my email address, so even though my family's email addresses are set up, they end up downloading my emails, so all email addresses download the same emails. I have never experienced this problem before and hope someone can help.

Greetings!

I have recently installed Thunderbird in order to evaluate its performance, with the intention of potentially transitioning from MS Outlook to Thunderbird if all goes well. However, upon connecting two of my email accounts, I encountered a Threat Alert from Windows Defender.

The detected threat is as follows: Threat Name: Exploit:HTML/IframeRef.T For your reference, I have attached a screenshot illustrating the alert.

Thank you for your assistance in addressing this matter.

My folders have disappeared. They are there when I first open TBird, but immediately vanish. I have checked ALL in view, but if I uncheck then recheck, nothing changes.

This only happens when clicking a link from an email in Thunderbird most of the time it is a news platform. I have to copy the link and open a new tab in Firefox to have it work.

Title. I've followed every guide I've found but the issue still persists. I've created a new profile, reinstalled ff after deleting the whole file from my pc, deleted all cookies for a dozen times, disabled all extensions, started ff in that problem mode or whatever it's called and I still can't login to certain websites.

I type my login credentials, press "continue" and nothing happens.

I hate how much information Google gathers from their users but I used Chrome for five or more years and I never had this issue with their browser. Not once. Even now I constantly have to go back using Chrome because with it I have no issues logging in to the sites while on FF I just can't.

What is going on?

I was having trouble with Firefox freezing and needed to close it with Task Manager and reopen it whenever this happened. On one of these restarts, only a few of my windows opened up with the new session. All of the other open windows vanished. They're not in my history or my recently closed windows at all. There are three specific windows of the lost windows that had data I was actively using and don't want to lose. The URLs would be enough. I was also using the other windows, but I can re-find that information easily enough.

Hi I went to my email provider earlier on and Firefox froze saying that a copy was running and to close - which I did. But Firefox will not access any website: just the normal waiting message.

I did a hard reboot. No joy. I tried a download. No joy. I am using Brave at present to access you. Everyhting else, email etc is working fine.

Any advice please.

Got online this morning, and Firefox "upgraded" to a newer version. Now, I have no home page, no bookmarks, no history, etc. This happened several "updates ago, a few years ago, if memory serves. How do I get all those back? Last time, they apparently sent out a "fix". Thanks,

I wanted to bump this as I never received a satisfactory answer for the reason behavior was changed and it is still something that feels like a UX regression.

Anything I open in documents, or pictures If I right click the Firefox Icon in my task bar it shows all recently entered. How do I stop this? I don't want this showing or saved.
