Thunderbird Community Forum

Over the last week or so, selecting a link embedded within an incoming email on Thunderbird does not now ensure that the desired webpage will be opened in Safari and other browsers. Shutting down Thunderbird, intermittently enables the proper functional activity of opening the desired webpage. I've discussed this with Apple (iMac; Sequoia 15.7.5) and was unable to identify this as an Apple problem.

Je n'arrive plus à me connecter, voici le message d'erreur "Échec de la connexion depuis le serveur imap.sfr.fr avec le nom d’utilisateur beaudonnat.jean-luc@neuf.fr. Pouvez-vous me dire ce qu'il faut faire pour me connecter. A savoir j'ai changé mon mot de passe mais celui-ci ne me permet toujours pas d'accéder à mes mails.

Hi, as of 14/4/26 my K9 (Samsung mobile) and Thunderbird (Mac Pro) no longer works with my bt internet account. Cannot receive or send emails. Have checked both in and outgoing server settings and all agree with bts advised settings. When I attempt to fetch in K9 I get error “network error readstringuntil():end of stream reached. Read:””while waiting for’’. When I attempt to send get message “unknown error unexpected end of stream. Contacted BT and they told me all my settings were good. I suspect something has changed at the BT server end. They did say they had relocated?? Any one else suffering this?

When I receive an email that includes a live link it does not work when I click on it. Instead I get a popup error message that says "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item."

I can sometime manage to copy the link address and paste it into a browser but this is not always successful.

I get the error "connection to server pop-server.triad.rr.com was reset" when running Thunderbird and then I get no email.

Don't know if it is relevant but I did try VPN beta in Thunderbird some time before the above error happened.

Regards Tom

PS I can't get any email if you respond to me there.

Recently switched ISPs to a fiber internet company. After the switch, now whenever I try access my comcast email tunderbird gives me a message that my IP is temporarily blacklisted. I get two messages. One is a windows notification that says the blacklisted message, and then a popup message from tunderbird that it cannot log in. I have contacted my ISP to ask them what's up with the blacklist, but what's weird is that I can seem to access these accounts fine through Outlook, which would seem to indicate that there is some issue with tunderbird. I'd really rather use tunderbird than outlook. Can somebody help me with this?

The few articles I could find on this all suggest changing the IPv6 setting but I checked that and it is already set to what they suggest.

I tried deleting the account and recreating it in tunderbird, but it won't go through it says it can't log into the account.

When I attempt to access the Add-Ons service through Thunderbird, it brings me to an HTML page (https://addons.thunderbird.net/en-US/thunderbird/search/?q=lastpass&appver=147.0.1&platform=Linux) reading

> addons.thunderbird.net > Performing security verification > > This website uses a security service to protect against malicious bots. This page is displayed while the > website verifies you are not a bot.

with the following footer: > Ray ID: 9d07fae58cabaefb > Performance and Security by Cloudflare

It will attempt to connect to Cloudflare to verify a Captcha, but the Captcha itself never renders, and after a period adds the following to the text:

> Why is this verification taking longer? >This verification can take longer due to an older computer or a slow internet connection. > What to do next: > # Wait briefly. Refreshing the page will restart the security verification and may take longer. > # If the verification still does not complete, refresh this page. > # If you are still stuck on this page after a page refresh, refer to Cloudflare’s troubleshooting documentation for more help.

After another period it then cycles the verification page. This continues as long as the tab remains open.

Opening the link listed above in Firefox opens the Addons page as expected.

Similar Captcha pages open on launch, as well as when accessing support or attempting to create a Matrix chat account.

There is a potentially related issue in that images and some icons are not rendered. I will make a separate post asking for help with that if it is not related, but it seemed relevant to mention.

The problem has existed for a long time, and I have checked existing responses without finding a solution, but I didn't get around to asking about it until now.

I am using Thunderbird v. 147.0.1 (64-bit) for Linux with no extensions installed), connected via AT&T broadband service with no proxy set, running under Manjaro 26.0, kernel 6.18.8-1, with the XFCE desktop environment (that last is only mentioned for the sake of completeness). I am using GUFW for my firewall, but the problem persists when the firewall is disabled (something I do not wish to do regularly in any case).
