Thunderbird Support Forum

We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?

I've been using Thunderbird for years and have never had this problem. Since the upgrade today, after I run Thunderbird once and close it I can no longer start it up again. I have to reboot or use Task Manager to kill it in order to run it. This is on Windows 11. Please help - not an acceptable workaround for long. Optionally, how do I downgrade to previous version? I should know better than allow automatic upgrades.

Adding a couple images below, when it has started successfully it shows as one of the Apps in Task Manager. When I close it, Thunderbird drops into the Background Processes but doesn't end. I have to kill it here in order to start it again.

Start new Windows session. Start Thunderbird and works OK. Shut Thunderbird down and try to re-start during same Windows session and it will not launch. Reboot Windows and try to start Thunderbird and works OK. Alternatively, going into Task Manager there will be a number of Thunderbird processes running. If I manually end them all (while Thunderbird is NOT active) then I can restart as normal too. This all began with 124.0 Beta 1. Never had the issue prior.

Also, Thunderbird crashes if restarting within the app. By this I mean clicking the X it appears to close (excepting those persistent processes running) but "Restart Thunderbird" such as to launch Troubleshooting mode or from the "Restart to update Thunderbird" config crashes the app with 100% consistency.

Hi, I installed the latest Thunderbird on OS X Monterey for a friend and am using an Imap email account. Sending and receiving emails is working correctly. The problem is viewing what is in the inbox, it shows a certain number in the inbox but not all of those messages are showing up, some are missing. I've played around with the settings but I didn't see anythng that could help me out. On my own computer this works correctly, when I see a number in the inbox, it does show all of those email messages. Not sure what is going on, maybe it's simple like a setting not done correctly, or I missed something. Anyway, any help would be appreciated.

Thanks

There is an email account profile on my Thunderbird email program and I simply cannot get rid of it. I have tried everything including running the program as an administrator and nothing works. None of the instructions to remove an email account anywhere on this forum works. When I go into the account settings, there absolutely no selection for me to remove a particular email account/profile from Thunderbird. I have removed Thunderbird, wiped out all traces and profiles for Thunderbird, reinstalled Thunderbird and this particular account keeps coming back. I bought a new computer, installed Thunderbird on that, and this particular email account suddenly appears on the new installation on a new computer. I can't get rid of it. I brought both computers to a technician and they scanned for viruses, trojans, etc., etc., etc., and there is nothing there, but this email address account keeps coming back on any computer I have installed Thunderbird, including new computers that are new out of the box. The email account I want to remove is clogged with spam and tying up my internet connection and the ISP (Charter Communications) will not help me by eliminating this particular email account. I have followed multiple instructions I have found on this forum about how to remove an unwanted email account from Thunderbird and not a single one works because the selection to do this does not exist in Thunderbird. All I get is asked for a password for the email address that the ISP says doesn't exist, but it is being flooded with hundreds of thousands of emails that get sent to this email address in my Thunderbird program. Every time I run Thunderbird, it locks into this particular account and downloads emails until my hard drive is full and crashes. Is there a way to get rid of this email account on Thunderbird or do I just remove the whole program from my computer and use something else?

Windows 10 22H2, Thunderbird 115.5

Thunderbird periodically loses my saved passwords (11 accounts) necessitating the re-entry of said passwords. This has been happening for about six to eight months.

I have searched for solutions and have tried deleting the pkcs11.txt and secmod.db files but the problem reoccurs. There is no rhyme or reason as to how often this happens. If I new where the passwords were stored, I could copy the good password file back into the thunderbird directory.

Any suggestions would be greatly appreciated.

Thanks.

Running 115.5.0 and want to export my contact list to be able to use it in a spreadsheet. The export function in the Tools dropdown only allows for export of "accounts, messages, address books and settings to a ZIP file." What happened to the ability to export just the address book separately to a csv file? Please help. Thank you.

After trying to change the name of a large folder with a lot of important information I cannot access anything and when I do the following message appears:

Unable to open the summary file for Accounts on david.vasmer@gmail.com. Perhaps there was an error on disk, or the full path is too long.

Any idea how to restore my access?

Thank you to anyone who cam help

On opening Tbird I have started getting a Google pop up asking me to sign in to Google to continue to Tbird. This is just annoying as I can access all my email accounts without signing in to Google. I just have to close the annoying pop up every time I open Tbird. How can I stop this happening?

Numerous users of Thunderbird have expressed their total dissatisfaction with the recent upgrade, especially the new font and layout in the email lists. Why has the Mozilla team ignored requests to return to the previous load to restore the font and list displays? Do you expect users to support your product when they totally do not like the new version?

Hi Folks. About a year and a half ago I some how got hacked in communication with a help desk somewhere. From that point on , I have not been able to use my Thunderbird email. It asks for my password that I do not have. I have spent hours trying to reset it. I have tried a clean reinstall, but it recognizes me and asks for my password. I have my email addresses saved and would be happy to do a fresh install, but I have not been able to figure out how to do this. I am very much obliged for any help you may offer.

Dear support,

I installed recently Thunderbird 115.5.0 (64-bit) on my laptop running Debian 12.

I have a problem with the font size settings in the message view.

By default, the font size is very small. I can increase it by tuning in the top Menu. Tuning the Font size to 26 pt I get a readible text, see Picture 1. When I move to the next message, the font size becomes small again. Picture 2 shows when I moved and came back to the same message. The menu is shown, and the Font Size appears to be 26 pt in both screen shots.

I have set layout.css.devPixelsPerPx to -1

I have a userChrome.css, but it does not fix the font size in the message view. I wish I could know how to do that!

Thank you in advance for your help! Eric CM

I have spent the last TWO HOURS trying to find an answer to what should be a simple problem, and it seems not to exist!

I need to find out WHERE Firebird lists my email account PASSWORD.

I do NOT want to reset my password.

I simple need to know WHAT my password is, and since I set up the account [actually a few accounts] several years ago, my notes are evidently null and void, because none of those passwords seem to work.

My email is through verizon.net, which is one of the problems because they gave all of their email coltrol to AOL, which thouroughly sucks, and they seem not to have anyone who speaks fluent English who can assist me in FINDING the current password!

If ANYONE can help, it would be most greatly appreciated!!

Need to set up Thunderbird to receive emails from yahoo. Cox is transitioning emails to yahoo presently have two addresses : cliven@cox.net and daciaandclive@cox.net

I use dark mode (Windows 10 Pro, Thunderbird 115.4.2 (64-bit)). Fresh installation, fresh profile. When I reply to some emails, the reply text is not visible. The examples I saw were with a light (white?) background, but I'm not sure if it also happens with other backgrounds. But it's not all white backgrounds either, some emails with a light background I can reply to just fine.

The reply area can be dark with a dark grey font (slightly different color), or it can be white with a white font. In both cases, obviously the text I type is not readable.

Any idea how to fix this?

After decades of using Thunderbird it has amassed contacts. Even for my own contact it saves a contact like "lynn@szetosolutions". incomplete email addresses, or associated with DMV...just for my own email it has saved 7 versions and or affiliations. I want to clean up and remove the excess, inaccurate email addresses that keep auto filling my emails and reduce the constant annoyance. Can someone help me? I'm so grateful for any help.

I just got the new "supernova" update and now I can't find the stettings to place my tabs bar at the top of the screen. The old version had the tabs right at the top, just as a browser would typically have it as well (see new and old schreenshot for comparison). But I'm just unable to configure it that way.

Can anybody please tell me how to configure thunderbird to use all that wasted space at the top sensibly?
