Thunderbird — Fora społeczności

I have remote content blocked as a default. If I choose to view remote content **for an individual message**, there seems to be no way to reblock it, because the yellow bar with "options" disappears after you allow the remote content for that message. (Whoopsy! Changed my mind! Let's say I don't want the remote content to transmit that I opened the message a second time when I do so.)

Mail Content > Exceptions does not help in this case, since I allowed the remote content from a specific message, rather than allowing a wider permission, such as allowing remote content from a particular email address or website. Copying the message link into Mail Content > Exceptions (as suggested in an old post) doesn't work, either.

So it seems I am now stuck having remote content active each time I need to open that message?

Windows 11 Thunderbird = current at the time of this writing. (150.0.2 64bit)

I always get: "newmsg Trojan:WIN/SuspiciousAttachmentScript.a" and "C:\Users\newb\AppData\Local\Temp Trojan:WIN/SuspiciousAttachmentScript.a" from Mcafee when I open Thunderbird. I'm only getting this in Thunderbird and suspect it's a false positive of some kind. It's still worrying and I'd like to eliminate this. This has been going on for a couple of months. I've run several cleaners and anti-virus programs on the system, but it still returns.

thanks

I couldnt access my email rang a number they gave me and man took over my computer said he found all these problems then wantd $500 or $250 to get thunderbird back I said no and now I have lost thunderbird and all my folders. my email is X@bigpond.com

very recently perhaps with a McAfee or Thunderbird update , I am seeing a message that McAfee stops a threat every time thunderbird does a message retrieval. see attachments. I have checked my outlook account directly and deleted a bunch of messages but it persists.

Hi! I wonder how Thunderbird for Android works regarding security and privacy? If I use a Gmail account via Thunderbird, will I not miss the security features that Google provide, like warning for malicious/fraudulent emails? How can Thunderbird improve my privacy? I mean, Google will scan my emails when they are coming into or leaving the server anyways, I guess. And they will still let AI be trained on emails resting at the Gmail servers, so will there be any privacy benefits using Thunderbird? Please help me understand, because I have really liked Thunderbird for Windows and used it for many, many years when I had a Windows laptop as my main computer!

Hello, I use Thunderbird 140.10.0esr, installed as Flathub flatpak on Fedora Linux Kinoite. I just found out I have a folder in /home/<user>/.var/app/org.mozilla.Thunderbird/.thunderbird/1tniiwpw.default-release-1/storage/default/ called https+++www.googletagmanager.com. I wonder why I have this and what it does in the Thunderbird settings. It has something to do with Google's LLC, but I don't want to be part of that. I removed the folder completely and hope it won't come back, but I wonder. Who can tell me something more about this folder? Thanks.

Hello! No real issues or bugs to report, but I had some curiosities about independent audit documents. I appreciate the dedication to privacy and transparency, as I am sure many do; I've noticed that there are readily available audit documents for the Thunderbird Send and K-9 which is cool - are there any such audit documents for Thunderbird Desktop for Linux, or do the aforementioned documents sort of cover the same thing? If you could help me understand this (or perhaps point me to information or docs I missed), that would be appreciated!

Thanks for your time, --Mark

I have always used the default option to block remote content in emails, and I always see the yellow box. However, I happen to have admin access to a server that sends me certain emails, and it has logged when I opened emails from there.

Is it possible to somehow incorporate a virus/trojan checker into the software that is open source for Windows? I keep getting TONS of alerts from Mcafee that it caught viruses. Also wondering if this could be a addition to Thunderbird in a new release by incorporating something like CLAMAV into thunderbird software somehow?

Thank you for your help and answer. I hope I can continue writing to you in German as well?

I can't find a contact person and the name of my Mozilla account has been changed; is that normal?

Thunderbird Portable Help

Question: A number appeared after my email address, so "email" and "1954". Who is that? Is that normal?

Question: Thunderbird Developer Toolbox: Can you see in the program? Can you see my emails?

Question: Are there any Thunderbird users left who speak German?

Questions: Thunderbird Portable The archive option isn't updating? How long does the backup take?

Different Thunderbird versions display a programmed year date in the archive option. For example, 2021 in one version and 2024 in another. Is that normal? I can't change anything.

It's as if it's accessing some kind of backup and maybe even sharing it, and I don't know what's correct.

Question: Update Channel Ellipse Update Channel esr. Previously, there were different channels. Isn't another channel better? I've read that it's more stable than switching. Is that true? Information regarding the question below?

You are currently on the esr update channel. I'm experiencing stability issues with this one.

Thunderbird 148.0b3 (64-Bit) for Linux (Ubuntu 25.10) E2E encryption is "on" with OpenPGP and a key for this account

How to verify the signature a incoming message with a OpenPGP signature?

I am getting the message that a part of the message might be signed. If I click on the button "open and display" there is a new window with the plain text of the whole message but the signature is not verified. What's wrong?

I just set up a gmail account in T-bird. I can send, but I can't receive. It keeps saying there's no email to get. I use a read-only email app called Mailwasher. I AM getting Gmail email in that app, while it's on the server.

I have gone through the settings in T-bird several times. I even checked on the web. - I entered what you see below (in both Thunderbird and Mailwasher): '"Incoming Mail Server Settings (IMAP) Hostname: imap.gmail.com Port: 993 Requires SSL: Yes Username: Your full Gmail address (e.g., example@gmail.com) Password: Your Gmail password"

I even tried changing the password a couple of times (also had to do this in Mailwasher).

UPDATE: now Thunderbird isn't logging on and wants a new password (which I've done twice already). No reason why.

PLEASE ADVISE. Kami

Hello.

I just installed thunderbird for the first time and i really liked it but there is a problem some of my emails particularly from from Fiverr don't show Fiverr logo at the top within the email maybe that logo has linked wrapped in it on which i can click and it take me directly to my fiverr profile. These are official emails from fiverr. What i have tried: I tried every possible solution that i can get on internet. Show Remote content turning on and off, Turing Simplified view on and off. Turning of the Proxy from auto detect and Turning the DNS off. Fiddling around view settings. Changing settings in Configuration like mailnews.message_display.disable_remote_image, browser.opaqueResponseBlocking.javascriptValidator, browser.opaqueResponseBlocking, etc. But it didn't load the logo image and keep showing broken image place holder. This is also the case with my bank mail, my bank email sometime have an image with warning about OTPs not just text it also don't load. I also tried disabling the spam protection and i only use minimize to tray extension which i disabled to check if image loads or not ans tried to run it in Troubleshoot mode but no luck. I will really appreciate If anyone could help me and fixed the issue . :)

Thanks.

When Thunderbird injects a link preview into a message, it changes the text composition from Body Text (my norm and default) to Paragraph. This styling change persists even after I delete what look like the entire preview.

My fix for the current message is to select all and reestablish Body Text, then clean up left over mess.

My overall fix is to uncheck Settings > Composition > Add link previews when pasting URLs

Clearly HTML is required to create a graphic preview box in a message. I do not recall having turned link preview on to begin with, so I'm feeling opted in. Do Thunderbird updates download with this option turned off? ___

Another reason I eshew link previews is that they appear to establish connections to online assets without asking. How is this safe? As a software developer - and simply as a user - I have occasion to send people links that I don't want to connect with. To pick an easy edge case, what if I'm reporting a phishing or malware site? Just because I type or paste an URL into an email message doesn't mean I want to download anything from that source.

Curmudgery aside, I'm grateful for your help as always. Paul

Hi, somehow thunderbird forced me to use OAuth for caldav and carddav. (v140 on linux) Unless I've probably missed something this approach doesn't seem to have considered that people might use more than one device. In the past I had an application password per device with my mail provider. That password covered imap, smtp, caldav and carddav. The application password I could set with a specific name at my mail provider. If the device was lost, compromised or whatever I just deleted that one application password at my mail provider, problem solved.

Now a regular thunderbird setup has the application password for mail and 2 OAuth records per device under "Connected Apps" at my mail provider. But it is not possible to see anymore to which device the OAuth record belong, as there is nothing device specific coming along with these OAuth records, just an IP.

With that perspective OAuth weakened my security options, as I can only guess which OAuth record I have to delete in an emergency case. Did anyone who implemented that with Thunderbird considered that people may have more than 1 device? Maybe even more than 5 devices?

That OAuth approach looks unmanagable to me. Is there a way to switch OAuth off in thunderbird, until it becomes more useable in >1 device setups?

Cheers Tjareson

Hi, I just noticed that my computer has been infected by a trojan called "HEUR:Trojan.VBS.SAgent.gen", and I can't remove it via Kapersky...The trojan is found in the inbox file in Thunderbird. So it's not a file that I can remove (it's all code). Kapersky stated that these two files are the source of the Trojan (they are not found as an e-mail attachment in my inbox, it's all code in the inbox file in Thunderbird):

P000009384:Emirates_Marble-pdf.gz and P000009384:Emirates_Marble-pdf.vbs

So I'm simply wondering how I should go about to remove this trojan from my computer?
