Hi everyone

I used Refresh Firefox option and it created "Old Firefox Data" folder on my desktop.

Awesome stuff. Sadly I cant get rid of it, here is why:

1. At first it said that the folder is used by another program and I cant delete it because of that. Cool, I decided to uninstall Firefox and make a clean install, so I have space to delete the folder too.

2. Long story short, it didnt work. I removed Firefox and tried to delete that folder, but wait for it, yeah I cant because I need permission from MYSELF. Awesome stuff.

3. I decided to use safe mode, so I used run command to run msconfig and I changed it to boot in to safe mode. But wait for it! YES! Its bugged and I cant login in safe mode, because pin is useless and it doesnt give me option to use password, so after hour of various things I got back to my normal mode via CMD commands. THANK YOU MICROSOFT.

4. So now Im stuck with the lovely "Old Firefox Data" folder, which cant be removed normally, neither in safe mode and wait for it! NEITHER WITH ADMIN CMD, not even the takeown /f "Old Firefox Data" /r command. THANK YOU MOZILLA!

So is there someone knowledgeable enough to help me to get rid of that folder pretty please? Like really a lot please.

I just updated Thunderbird and any email earlier than 2/22/25 is gone. My sent items folder is empty and my address book is empty. Any email containing a link. The link will not work.

I hope there is a way to recover my missing data.

I recently installed Thunderbird on a new installation of Ubuntu 24.04 using the "Installing Thunderbird manually" instructions. Everything works fine except that Thunderbird doesn't want to use the Thunderbird icon in the dock. Thunderbird opens and runs fine when I click on the Thunderbird icon, but it then puts a new default icon on the dock that looks like a gear instead of just "using" the Thunderbird icon to indicate that the application is running. I've attached a screenshot. When I close Thunderbird, the gear icon disappears.

Having just re-installed Thunderbird I receive the following error message when trying to set up my gmail account, which had been working fine before

400. 

That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

The password is correct as I can login from my browser and I have easily setup my other email accounts - not gmail. Also have re-started PC and Thunderbird.

Help please, regards, Haydn

I hope I’ve chosen the correct category. I believe this qualifies as a bug following the recent update.

When I opened Thunderbird today, it notified me about the update. While Thunderbird successfully fetches new emails, it fails to display them correctly.

As shown in the screenshot, the area where the email content should appear is completely white. Additionally, it incorrectly displays an attachment from an old email that has nothing to do with today’s email (10:13), aside from the fact that both were sent to me.

When I click on other emails in the same inbox, the content area doesn’t change—it remains blank. However, if I switch to a different inbox, everything works fine.

I’ve also double-checked using my phone’s mail app, and I’m able to open the email in that inbox without any issues.

I’m unsure how to fix this. Could someone more knowledgeable help me out?

Dear All,

I think that is a compability problem of Citadel with Thunderbird email client.

After several steps to try to solve the problem I found that Citadel is not compatible with the last version of Thunderbird.

I tried Linux (Centos 9) and Windows Thunderbird. I tried my affiliation network and with my mobile hotspot.

I can send emails with my Android email client.

I am thinking to make a downgrade of Thunderbird. I have there all my emails from always.

But first I have to backup everything of Thunderbird. Time consuming task.

Some help is needed.

I just upgraded to 128.2.2esr and cannot receive or send messages after the update. I have restarted the computer and tried again - still nothing. I'm unable to use a tool that is critical for my daily needs.

Trying to send just says "Connected" or "Sending" but never completes. Worked fine before the update which was just in the past hour or so.

Same issues with downloading new email or sending email for all accounts. :(

Anyone else having problems? Ideas?

Thank you!

Hi, after an update, i have the newest version of Thunderbird installed. Upon starting, it says: "Unable to use profile when you launch an older version of Thunderbird." I cannot start the program. But it is the newest version... What can I do? Thanks Lukas

New to Thunderbird and to macOS. I need to create 3 separate profiles. I have successfully created one account, but I need two more, and I must not mingle the email accounts in a single profile. I have followed instructions to open ProfileManager but Terminal reports that the path does not exist. It doesn't seem to matter whether I quit Thunderbird, because the Terminal Response is the same (I have tried the command both ways, and restarted the computer after installation). The Thunderbird Help files point to Thunderbird 115 with macOS, but my installation download created version 128.2.0esr. Troubleshooting Information in Thunderbird Help shows the Application Binary as "/Applications/Thunderbird.app/Contents/MacOS/thunderbird" and that is what's indicated in the instructions to open the ProfileManager except it cannot find the -bin -P.

As additional background on my plight: I have only set up one user on the computer, and I am logged in as that user so Terminal opens in my user directory. I was pretty comfortable in a Windows (up to 8.1) environment, and am struggling with my move to the Mac, so it may be that I don't have permissions or some other setting set correctly to do this, but I don't know what to look for.

Any help would be much appreciated! Thanks!

I downloaded Thunderbird, set it up with 3 email accounts played around with it all afternoon, closed it then when I try and open it back up it's like it's not there at all. It takes me back the the 'thanks for downloading page and opens the bit for me to set up a new email. There are no folders there at all. All I can do is start afresh and enter the email addresses again. This can't be right???....

Hi,

I am running Thunderbird 128.2.0esr (64-bit) on Ubuntu 24.04.1 LTS

Since around the beginning of September, I find that my Local Folders, which still seem to be storing new emails ok in Thunderbird, are no longer mapped to my "~/.thunderbird/<profile name>.default/Mail/Local Folders" directory tree.

Thunderbird seems to have changed its behaviour in this regard around the start of September.

Has anyone else experienced this?

Any idea where the "Local Folders" emails might now be stored on disk?

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

I have a IP intercom that only works with Firefox 127.0.2 Now Firefox automatically upgrades to the latest version and I'm unable to prevent this. I'm unable to manage my intercom with the latest version. How do I turn off automatic updates.

I converted as advised and then updated to the newest version. I lost everything except the messages: the Address Book, Tags, Message Filters, and Folders are all gone. This is a disaster after 15+ years with Thunderbird. It started when I copied the folder "profiles" from my laptop to my PC for the 1,000th time. Is there a simple step-by-step solution? Without the history or apologies etc. etc? Just "do this?" My solution now is to do all my email on my laptop. Ugh!

I uninstalled thunderbird and when I try to reinstall it I get a "cannot find temp archive" message.

I've installed thunderbird for another user on the same computer and had no trouble.

Can anyone help me? Thanks so much.

Had to re-install Windows 10 Pro 64 bit. Saved Tbird Profiles folder to USB thumb drive. Re-installed Windows then installed latest Tbird version (same one I was using). Opened Choose User Profile > Selected Create Profile > Selected Use the selected profile... > Exited Choose User Profile.

Then went to the thumb drive > Opened a profile folder > Copied everything > Then pasted it into the new profile folder I had just created. Opened TBird but it didn't have any of my settings or emails.

The thumb drive had 3 profile folders in it so I repeated these steps for each folder. But still didn't get my settings, etc.

What am I doing wrong?

I was automatically updated to 128.2.3esr (64-bit) and immediately I have lost the ability to create new subfolders in any part of my folder tree or on any of the accounts I use. Rt-click -> New Subfolder has always opened a little dialog box to name the new folder. Now nothing happens. I have seen a similar user issue reported, but the answer was long and incomprehensible and seemed purely to relate to spam boxes and certain user account types . The issue is still not marked as resolved and is a real pain. Is there a simple way to roll back to the last version while you figure it out?

Best Regards
