Thunderbird Support Forum

when I try to start Thunderbird, I get a window that says "Your computer must be restarted to complete a previous upgrade Thunderbird. Do you want to reboot now?. I've rebooted several times now, scanned with PC Matic, rebooted again, tried to uninstall in Control Panel, and get the same window. How do I fix this?

I have Thunderbird 125.0 (64-bit) on Win 11.

Everything works perfectly, BUT..

If I select File->Exit then it just goes into not responding mode and I have to end task to restart TB.

If I just click X then the window closes but If I click my thunderbird icon to bring it back up, nothing happens.

I often have multiple TB processes which I have to kill.

On system restart, everything is fine unless I try to exit TB.

In case it matters, I have private ISP email acc, and 1 hotmail and 1 gmail acc.

Any thoughts appreciated.

Thanks Steve

My mail is hosted on Hostpresto. Yesterday 'someone' (it wasn't me. I was in bed) gained access to my cPanel and email and deleted my only email address, then installed their own. All my mail gone. I was stupid though - I opened another email address with the same name as the old one and started Thunderbird on the pc. Of course, it synchronised to the empty folders!

Luckily I have another instance of TB running on another machine and it's all there - I am not internet connected there!

How do I bring the folders containing all the old mail from the 'safe' machine's appdata/roaming/thunderbird location to what will be my 'working machine' without it immediately synching to the server and deleting it all?

Thanks Andy

When I receive emails from addresses that are cell providers, ie. (tel #)@vzwpix.com or (tel#)@mms.att.net, the text is in an attachment that I need to open separately. Is that an issue within Thunderbird settings?

The height of the viewing panel for emails is far too small. I can only see a couple of lines of text at the most and am unable to reduce the height of the incoming list of emails as previously in order to increase the height of the viewing panel. I have been helped to increase the font size of the overall layout so that I can now read it better but the green button to declare that my problem has been solved tells me that the page isn't working!

I do not write code nor do I understand it. I am only a user of 20+ years and I loved it until I updated to Supernova. This is my latest question.

I have an email string of 20+ emails with a single client. When I open one of the emails, all 20+ open in separate windows. Additionally, I now have to search for emails that are responses to the original. Every time my client responds, the most recent email gets added to the string somewhere within Thunderbird, other than in my inbox. This makes no sense.

How do I get back to opening one email at a time when there are multiple responses to an email. Attached is a screenshot of what I found during my search for one particular email. What is the icon I have circled? It is the first time I've seen it.

Supernova is extremely disappointing. Is there any way I can downgrade to a previous version? Is there any tech support other than the community?

Any support would be appreciated. Again, I don't understand code, so you may have to dumb it down some for me.

Thank you.

Hello

I have been using Thunderbird as my email service and not had this before. Yesterday, I had to change my password for emails with BT. I changed it on Thunderbird too but now I am receiving emails OK on Thunderbird it is refusing to send any for me and shows the above message. I can send OK from my web based BT email but prefer Thunderbird.

I haven't a clue what I need to do to solve this.

Can you please help? Please tell me is very simple steps I'm not very computer savvy.

Thank you

I am using Supernova 115.4.1 and wanted to see if there was a way to make the very small "cloud" download mail icon at the top of the folder pane bigger, or change it to a more visible icon. I removed the general "Get Message" bar that was at the top of the Menu Bar since that one downloads mail in ALL mail accounts on TB - which I don't want. I want to have the icon that downloads just individual account - but I'd like it to look like the the larger one.

Images below - first is what I want, but for it to be at the top of the folder pane next to the new messages bar and replace the little cloud in the second image.

Is there any way to do that?

Thanks!

I had version 102:15:1 up and running after I had new terrible version 115 removed. Now during an update TB/Mozilla reverted me back to 115. Now I do not seem to be able to downgrade back to 102:15:1 again. WHY Help would be gratefully received. Thanks

In my left tool bar I have:

xxxx@cox.net pop server followed by about 40 folders. This was the Cox email that is no longer in use.

xxxx@gmail.com followed by folders

xxxx@cox.net this is the new imap cox.net using yahoo.

Is it possible to move the bottom cox.net to the top, followed by gmail, followed by the no longer in use pop cox.net?

Thanks

This bug was reported 28 days ago and has yet to be resolved. https://bugzilla.mozilla.org/show_bug.cgi?id=1857734

The temporary fix for the unpopulated unified folders including the Sent folder, and the issues with missing messages, some showing up in individual folders and not the unified folder and vice versa were just that, temporary fixes. Yesterday, the Sent folder was back to being unpopulated, and the individual folders containing my important and starred messages were all open for some mysterious reason. How this happened out of the blue is also a mystery, because I was not notified of an upgrade. If upgrades are installing on my computer without my permission, this is completely unacceptable. This is a subject that needs to be taken seriously at this point.

from today I cannot download my gmail to Thunderbird, I'm getting always here below error code:

“400 invalid_request” or “Access blocked: App sent an invalid request,” it means the app uses an authorization method that Google doesn't allow. Google has safe ways for you to sign in and share your Google Account data with third-party apps and sites.

Please let me know how to proceed.

Thank you

I drag-n-dropped an account (POP3) folder "inbox" to the "Local Folders". How can I return the "inbox" folder back to my account folder ? Drag-n-droping back does not work.

Hi, I am looking for some help. I am using Windows 10, Comcast internet, and a VPN. I get error message when my VPN is on saying that my IP Address has bee blacklisted and I can not send or receive emails using Thunderbird. I also get an error within Thunderbird. My VPN Service says its either Comcast or Thunderbird. Been working with Comcast on the issue. Could it be a Thunderbird issue? My VPN Service says to reinstall Thunderbird but no guaranties that will help. Please let me know if there are any solutions I can try. Otherwise I may need to pay more for a dedicated IP Address. Thanks Marc

When I want to print an email I want the body of the email and I do not want the header information. How do I remove this unwanted script at the top of the email? I have tried ticking and unticking the tick-box for headers and footers in the print dialog to no avail. This question has been asked before but was archived.

The font size for the whole display is far too small. Also the viewing panel for each email is far too narrow but the text when writing emails is huge. Should I go back to an earlier version?

Please find attached screenshot. I have added 10 email accounts for 5 domains. Most of them are unified since I used the "unified [folders]" option. Unfortunately, Thunderbird ignores several email accounts. This seems like a bug to me.

I have been trying to use Paypal to donate to Thunderbird. It just keeps giving error message "something went wrong" The Contact Us link on the Donations page didnt work either so I had to fiddle around getting to this page. Also sent question to an Admin. Very frustrating
