Thunderbird was sending and receiving emails with Charter.net but not stopping working with error 'timed out'. I have checked and rechecked the entered info and also called Charter and they have been verified as correct. Thanks!......Candy

Yesterday Thunderbird worked just fine. This morning I tried to respond to several emails and got this error message: Sending of the message failed '"An error occurred while sending mail. The mail server responded: [VO=1] Message blocked due to spam content in the message. Please check the message and try again."

There was no spam in the person's email... just text.

Next I tried to send a freshly created email with just a YouTube video... then the last half of the error message said: An error occurred while sending: RBL restriction: Blacklisted by Internal Reputation Service - 195.181.168.179

What is going on??? The SMTP settings are correct: Port 587 STARTTLS Help!!

This is the 3rd time I have had to post this. I am getting very frustrated. I DO NOT want the search engine within my address bar. Nothing anyone from you "community" helped to disable the search engine in my address bar. Opera, Edge, Chrome, the user can disable the search engine in the address bar. Why is Firefox so different? And difficult?

For months I was experiencing the problem of "Thunderbird not responding" occasionally. It was a short duration issue (a few seconds to a minute). I reinstalled Thunderbird several times without success. I read almost every comment available online about this problem and I tried many ideas and recommendations I found without success. Most recently the problem became so serious that it was not a nuisance any longer. It was nearly impossble to work waiting for minutes to open an email or to continue typing while preparing a message and being interrupted by the problem I am describing. I ran Thunderbird in safe mode and determined that none of the add-ons is causing the problem. I turned the firewall OFF and determined that firewall was not causing the problem. I then decided to run Thunderbird in Offline mode and found that the program works normally. Then while in Offline mode I decided to download more messages and the program asked me if I wanted to switch to the Online mode. I said yes. New emails were downloaded and without going back to the Offline mode I was able to work normally without any occurrence of the "Thunderbird not responding" problem. I have been using this workaround for several days now. I download a number of eamails. I try working in Online mode and I cannot do it. I switch to Offline and work fine. I switch back to Online mode and I don't see the problem any longer for the whole day. Do you have any idea as to the origin of my proble? I am running Thunderbird 115.10.2 64 bit on Windows 11. I had the problem originally using Lenovo T490s and more recenlt Lenovo X1 Yoga

for some reason my youtube tv claims it needs to be updated so can not watch tv in settings it claims to be the latest version 115.29 but google claims it is 144.01 so have no clue how to update if that is why I can not watch tv trying to ask mozilla is pointless with there b/s excuses which is part of firefox

Functionality and usability issue: I use the Thunderbird for Android app as an adjunct to my desktop installation. Recently I had occasion to reply to an email in Android to one "to" recipient and needed to add two "cc" recipients, but found no way to add the cc recipients without deleting the existing cc recipients and having to input the entire (dynamic) group again, but then was also stymied by that. How best to handle this issue?

Other than that issue, the lack of desktop contacts synching, and the lack of spam filtering, Thunderbird for Android has been a huge help, so thanks to the developers for their dedication and hard work.

Von der Erstinstallation war ich gewohnt, dass von oben nach unten die Darstellung der Ordner wie folgt war: Posteingang / Entwurf / Gesendet / Archiv / Spam / Papierkorb / Local Folders /Postausgang / Unbekannt Nach der neuen Installation, die erforderlich war (Rechnerneuinstallation) ergab sich folgendes Bild von oben... Lokale Ordner / Papierkorb / Local Folders und dann alle meine selbst erstellten Ordner am Ende dieser Aufstellung kam die Zeile mit meiner web-Adresse xxxx.xx@web.de dann Posteingang usw. siehe oben aufgeführt Damit liegt der Posteingang am Ende meiner Ordner Auflistung und das ist über den unteren Monitorausschnitt hinaus, diese Situation ist für mich untragbar und deshalb werde ich wohl auf ein anderes e-mail Verwaltungsmedium umsteigen müssen. Eine Kopiermöglichkeit um die Ersteinstellung zu erreichen war kläglich gescheitert und jetzt ist das Durcheinander noch größer beste Grüße B. Bein

Firefox 136.0.1, Linux 6.8.0-55, have set Okular as default pdf application, however Firefox will not open pdf file when downloaded nor will it open the file when selecting Open File from the Download Icon on the toolbar. Only was I can get to file is to select Show in Folder option and open from within Dolphin.

When ever I open an e mail from an originations the Images (pictures) do not appear only a box. Some time when I click on the box it will open something. Tere is nothing in the boxes to indicate what it is. See attached screen shot.

Hello, Sorry to disturb but its been two days and I am unable to access my Google accounts (work and private) through Firefox in anyway. I have done all the basic fixes I can think of but with no success. I have deleted caches, checked plug ins, rebooted Firefox went through the trouble shooting mode, followed advice in the community forum, tried logging in from Google linked accounts. Spoke to our internal IT support at work but nothing has solved the issue as yet, spoke to Google support.

My assumption is that it has to be the browser as I am able to log into google with another browser but Firefox is my preferred browser and would like to use it again as such.

Please advise.

Thank you Cait

I am trying to whitelist a domain name. TB won't let me do that. This company has a plethora of emails. I don't want to whitelist every single one of them. That would take me days. It is impractical. I want to whitelist the domain name which is concentrix.com. I want to ensure that all emails coming from that domain name land on the inbox folder. How can I do that on TB?

the default font for writing texts is too small for me to easily read. Yet when I send the message the text size too large, How do I control these font sizes independently

I am trying to upgrade from ESR to Release. I saved my profile successfully, went to the install page and clicked Download. Got a request to donate, which I did. Then I got a page saying Thank you, Finish installing and enjoy Thunderbird. But there is no way to finish installing and I never got a download file. I've tried multiple times, nothing happens. Help!

When I go to see a firefox bug such as the following, https://www.mozilla.org/en-US/security/advisories/mfsa2026-10/

There appears to be more details in https://bugzilla.mozilla.org/show_bug.cgi?id=2014390 located at the bottom. When I try to view the details it asks me to log in. I do not see any reason I should have to log in to view the issue as I only intend to view the bug. Why does it require a login ?

I just got a new computer running windows 11 pro. I downloaded Thunderbird, which I used on my old computer(windows 11), and followed the steps to set up my email. I know my email address and password are correct as well as the server settings and I keep getting the following error "Unable to log in at server. Probably wrong configuration, username or password". My email is .verizon.net which is handled by AOL. My husband also uses Thunderbird and verizon email and I checked the configuration against his computer and everything matches. I was able to get my gmail account added so it must be something with aol or windows 11 pro. Any help is appreciated.

Hi all,

I have tried on K9, and Thunderbird Mobile.

On my tablet, with K9 mail, I exported my fully working accounts, and imported to my phone. All worked, except one account, where it only has an outbox. No inbox, no sent folder, nothing.

I then Installed Thunderbird mobile, and used the QR code link in the desktop app, to sync to it. Same issue. All other accounts work fine, but not that one account. Only an outbox.

I've logged into the web version of that account, and no restrictions are on folders. And it's only on my phone. On tablet it's fine.

I can't even choose folders in settings, for sent, etc, as there are none to choose.

Any help would be greatly appreciated. Thank you

I am using Firefox nightly on Android. About two weeks ago I noticed that my toolbar got moved to the bottom after some update, while address bar is still at the top. I tried looking for it in settings but couldn't find anything about toolbar, that's weird since I was able to customize it a few years ago when I installed Firefox for the first time. So I looked it up on the internet and they say that it's in Settings/Customize/Toolbar, but in my browser settings instead of Toolbar there is Address bar settings. Has toolbar's settings been moved somewhere else? It looks like in previous versions it was under Customize section.
