I always use Mozilla Thunderbird for email. Today, it would not send outgoing email. Any email gives me a failed message: "Sending of the message failed. An error occurred while sending mail. The mail server responded: Spam detected by content scanner. Message rejected (ID 665754780026FB52). Please check the message and try again."

My ISP insists the problem is not with their server, and I need to have Mozilla correct it.

Some mails always end in spam folder no matter which settings I have tried for example collected adresses or check/uncheck spam settings. For a test I have two hotmail accounts. When I from thunderbird send mail from one to the other, it ends in spamfolder. But if I from the same mail account from outlook.live website send mail to the same account, it doesn't end in Thunderbird spam folder. Besides this many other safe and regocnized mailaccounts recently starts to end in spamfolder. Can any thing be done?

Yesterday firefox private window comes up on my browser...I do NOT want that, how to get rid of it?? My desktop is set up with menus for quick reference; I cannot get past this private window

Hi, I´ve some Outlook accounts with two step verification login. Anytime I open Thunderbird I´ve to verify myself by selecting a number on my mobile. Is it possible that Thunderbird get´s directly to my outlook account without that veryfying process? Thanks for answering.

I use firefox (as mozilla) for decades ago. Never had issues, is super easy, fast and ...secure (?) A hacker last week have access on my Firefox, download ALL my saved passwords as CSV... as a plain TEXT and ATTACKS on my entire life!!! And the nightmare goes on and on... Stole my primary Google Account, Facebook, Instagram, Ubisoft, PayPal, Microsoft Account.... and other 20 sites beside this. For GOD sake, didn't you EVER think to place an extra security layer on this EXTREMELY SENSITIVE details??? A master password? 2FA or something else? Are you serious??? I'm so sorry BUT YOU'RE LOST MY TRUST!!!! Period!!! Give a change to your selves and PROTECT YOUR CUSTOMERS!

I can no longer connect to X ray images using your browser. The links are in EPIC. The X ray system is eUnity. If I can no longer connect I will have to switch browsers.

Your browser says: Secure Connection Failed

An error occurred during a connection to webpacs.cei.med.umich.edu.

Our app sends an email advising the specified individual to note a series of images presented in three rows of nine. The rows display in Gmail via Windows->Chrome, via Android, and iOS with a Yahoo account.

But not in Thunderbird. This is a serious issue as I believe I have followed all the correct settings including in-line display, and yet for some reason, Thunderbird does not display the images.

Any suggestions are appreciated as I am baffled since Thunderbird has been my go-to email client for years.

How do I turn on autofill in firefox 125/126? There are help pages that say go to settings>privacy> and turn autofill on. But there is no autofill mentioned anywhere in that page. The only reference that autofill comes up with when typed in the search bar in settings is in import settings. How is this so difficult to enable, its basic functionality 10 years ago. I've also tried going to extensions.formautofill.supportedCountries and extensions.formautofill.addresses.supportedCountries and adding my country (why this is a thing is bizarre as well).

Firefox periodically says I am "forbidden" to enter my Kaiser website (KP.org). I know what Mozilla recommends as a fix, which is to clear data and cookies. But this creates more problems because I have to re-enter passwords and other settings. This is a problem Mozilla's website reports has been occurring for YEARS! Why can't Mozilla/Firefox fix this? Please tell me there is a better way to fix this problem.

I installed Thunderbird and downloaded the mail (IMAP server) to the mailbox, but at the same time the program deleted all the mail from the server!!! I can't find anywhere in Thunderbird how to turn it off so that the program doesn't delete messages from the server. Someone suggested that you should turn off "the selected folder will be available in offline mode" in the Synchronization tab. I did it, but it didn't help and I turned it on again. Now I don't have my messages anywhere, neither on my computer nor on the server. Rescue news from ten years - where are they????

Hello everyone! I am having a pretty strange issue with my [website ], it shows an SSL certificate on all the other browsers, but, on Mozilla Firefox, it shows not secure issue, which is quite pressing. Can anybody tell me what's wrong here?

I have an issue trying to configure a secondary email account, for a non-profit I do some work for. It was ok in the past, though I recall was tricky to set up on TB a couple of years ago. But now it has ceased to function after I migrated TB profile (successfully apart from this issue) no matter what I try. I’d be grateful for any suggestions. As is the case with many non-profits, there’s little tech support, but others can use the email account ok. I think it may be a TB issue as I have been able to set up the account ok with MS new Windows Outlook app (lame, but better than Mail…low bar). I’d rather have this account on my TB client along with the others I use. And the issue is replicated on two of my PCs. TB account set up reports “can’t detect settings from host server”. I found a support thread link text, which says “The failure to detect settings is rather common where hosted domains are concerned. Mostly because everything is done to a price and most of the things around encryption are done in a halfhearted manner. As is the server setups for mail. However by faithfully copying the settings from the provider as to domains server name and ports it should work.” So I did manual configuration – copied the settings from the successful Outlook set up, but no dice – all I get is server time out message. Settings are: IMAP server: mail.XXXX.org.uk Port 993 Security SSL/TLS [earlier working settings were STARTTLS port 143] SMTP server: mail.XXXX.org.uk Port 465 Security SSL/TLS [[earlier working settings were STARTTLS port 587] And using Normal Password for both; I tried Autodetect too but no good. I’ve see a suggestion that turning off the firewall (Norton) might work, but I’m reluctant to do that and doesn’t seem to make sense that would cause the issue. I found another suggestion that apparently works for some people - leaving password blank on setup. https://support.mozilla.org/en-US/questions/1399690. Before I try, are there any other suggestions or ideas? Trivial matter in the long run, but bugging me. Thanks

I am migrating to a new laptop. The new laptop keeps asking me for a primary password. I have never set one up. This issue doesn't happen on the old machine, only the new one. It also won't let me disable the pop-up that asks for the primary password. Please advise.
