Previous version, if I added a new bookmark, I would be presented with options on Where(Folder) and Tags. This is no longer offered, and bookmarks are just added to unknown within bookmarks Q. What has changed, and how do I get this option back?

I noticed of late that the Firefox Taskbar icon is no longer recognizable on the Windows 11 Taskbar! It is no longer a circle showing a fox but is a rectangle with a dark square like thing in the middle with very tiny dark spots in lighter areas. How can I get the original icon back that is recognizable as Firefox?

Thanks

Chase bank online is now requiring a later version of Firefox than my Mac will support. I currently have Firefox version 115.30.0esr. Now I am unable to access my account on line to see purchases. What is my work around? I thought there was software that could be installed to "spoof" chase into thinking I had a later version of Firefox. Both of our computers are from 2011 and 2012 so neither one will accept the latest version of Firefox. Many thanks in advance for any advice.

Bonjour, J'ai un problème pour imprimer depuis Thunderbird. Lorsque je tente d'imprimer, mon imprimante Brother s'affiche momentanément, puis un message d'erreur apparaît indiquant "L'imprimante choisie est introuvable". J'ai supprimé mon profil de Thunderbird pour paramétrer à nouveau le logiciel avec mon compte de messagerie et j'ai réinstallé proprement mon imprimante Brother. Je précise que je peux imprimer en dehors de Thunderbird. Est-ce que vous auriez une solution à me proposer ? Ci-joint, une capture d'écran du message d'erreur. Cordialement. Cyril.

Hi

I need to block some sites through the OS Hosts file, Other browsers ( Edge, Chrome, .. ) are honoring the HOSTS file rules but Firefox bypassing them !! , I disabled the DNSOverHTTPS and all other available suggestion and options but still not honoring the hosts file !

as you can see in the attached file, the Firefox DNS Section is now blank ! but still doesn't follow the OS host file

I even made a custom policy file but still doesn't work, these are the things I disabled but still not working :

{

 "policies": {
   "DNSOverHTTPS": {
     "Enabled": false,
     "Locked": true
   },
   "Preferences": {
     "network.trr.mode": {
       "Value": 5,
       "Status": "locked"
     },
     "network.dns.native_https_query": {
       "Value": false,
       "Status": "locked"
     },
     "network.trr.uri": {
       "Value": "",
       "Status": "locked"
     },
     "network.trr.bootstrapAddress": {
       "Value": "",
       "Status": "locked"
     },
     "network.trr.exclude-etc-hosts": {
       "Value": true,
       "Status": "locked"
     },
     "network.dnsCacheEntries": {
       "Value": 0,
       "Status": "locked"
     },
     "network.dns.disableIPv6": {
       "Value": true,
       "Status": "locked"
     },
     "browser.fixup.dns_first_for_single_words": {
       "Value": true,

Yesterday, I thought I had my original problem with TB fixed by installing v140.5.0. Well, things just got worse.

While trouble shooting it today, it AUTO UPGRADED to v144.0.1.

Hi there,

I need to export my thunderbird account over to outlook.com. I'm hoping to just sign into outlook.com and add my current thunderbird email details for j.childs@mhslimited.net.

When trying to add this as a POP or IMAP I get an authentication error once applying the incoming/outgoing server and port details.

Can you please help with what details I need to do the above.

Thanks

11-14-25 I have a Dell Precision M6700 laptop running Outlook 2007 under Windows 7 64 bit Pro. I have a Dell Precision 7720 laptop running Thunderbird under Windows 11 64 bit Pro. So far I have been unable to export the Outlook.pst file from the M6700 and import it into the 7720. I have tried to find a free version of a pst to eml converter, but the free (or trial) versions only seem to convert a few files in each folder. So assuming pst to eml conversion is the first step, I need recommendations for reliable but reasonably priced conversion utilities so that I can export the files from Outlook 2007.

I have tried to import converted eml files into Thunderbird, but the Thunderbird import software seems to be looking mainly for a profile which I don't know where to find. And besides, it appears that Thunderbird is designed to do the export/import operations on the same computer, not two computers as in my case. Anyway, I get an error no matter what I try. If someone has insight into these various steps, I would greatly appreciate some help. Thanks!

Hi everyone,

I'm trying to add my school email address to Thunderbird, but I keep getting a "Unable to log in at server. Probably wrong configuration, username, or password." error. I know that the username is right, and for the password, I've tried using the right password vs. leaving that field blank. For the configuration, I don't know if that's right.

The auto-configuration finds a configuration in the Mozilla ISP database, but that configuration leads me to the aforementioned error message. If the configuration is wrong, how would I go about finding the right information?

Alternatively, might it be the case that my school (the organization) has disabled using Thunderbird for our email. For any help looking into this, it's a @berkeley.edu address.

Thank you for your help!

I'm not able to log into yahoo e-mail via Linux Firefox (145.0 (64-Bit)): The error message is "We were unable to log you in. Please try again from another device." I can log in with Chrome (Linux and Windows) and Firefox (Windows). My issue is to switch from POP3 to IMAP in Thunderbird. There the same error message occurs.

My email provider is terminating the existing email domain name, and replacing it with a new domain name. I want to retain all existing Thunderbird folders and emails for use with the new email. Example: username@q.com becomes username@myclk.com. (Yep, it's Centurylink.)

Can I change my existing Thunderbird account name and email and retain all existing folders and emails in the account? Some server settings would also be changed.

Or, do I need to set up a new account?

Thanks

Hi, I'm using Thunderbird version 140.0 on Windows 10 and trying to change the background of the message pane. I've tried:

1. messagepanebox {

   background-color: #e6f3ff !important; 

}

but it only changes the upper part and I can't find a way to target the whole flex container or the lower part. There is a forum response (titled Message preview pane background) that targets the message pane:

1. messagePane {

background-image: url("file:///C:/path to image/image.jpg") !important;}

and that fills the message pane when its blank at startup but it disappears when selecting a message from the list.

I can add the background-color statement to :root in Developer Tools and that only works for the current selected message. How can I change the background of the entire Message Pane - the upper and lower part that contains the contents of the message - for each message that is selected? Thanks, David

How do I make a backup copy of my Thunderbird email client, saving all the subfolders? I would like to then uninstall Thunderbird and then reinstall it, as a new user, and without losing any of my old user folders. Thanks. After I do this, will I be able to reload all the old subfolders and read those messages?
