Hi,

I have a Mac with Sonoma. Somehow a while ago I ended up with Firefox ESR, which I was told that will not be supported after September.

I am a non-technical user. While I do have Safari and Chrome, I would prefer to continue using Firefox.

Could you please let me know the steps to execute to somehow switch from the ESR version to the current normal version without loosing settings, bookmarks or ending up with problems? Thanks in advance.

The inbox had about 18 months worth of emails. I deleted three emails that had been flagged by Thunderbird as spam. Then I went to the trash folder and permanently deleted the trash that included many other unwanted emails.

When I returned to the inbox, the full list of emails was present but after clicking on any email there was no email content shown. A new email came in and the content was shown for that email.

The sent folder still shows all the sent emails.

After looking for solutions on the web, I selected the inbox, right clicked and opened properties. I then selected "Repair Folder". Now, the only email shown in the list is the new email that came in after the issues started.

I have looked for crash reports and it says there are no crash reports.

Suggestions....? Thank you, Peter

Good morning Windows 10, TB 115.11.0 32 bit. Multiple email accounts, some gmail, others like sfr, lol and free. All accounts use POP. All working before weekend, shut down the PC. Monday morning, opened Windows, all seems there except TB which has a screen with an Account Setup tab inviting me to set up an existing email address. Close that tab and the attached screen image appears, open tabs blank, no accounts pane on the left, no emails, no local folders. Nuffin. Restart TB and Windows, twice, still Nuffin. Look in Profiles, yes, under Mail all profiles appear to be present and the correct size. Going to gmail’s on line email system shews account open and receiving email normally. I had a problem a month ago after a TB update when all accounts were present but no emails were displayed. I changed the password to 0auth and recovered my emails. That took three days to resolve and I lost a business client through the delay in responding. Today I must file several court documents or I shall be in deep poo. Any suggestions how to recover the left hand accounts pane and see the accounts and folders will earn my undying gratitude.

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

I created a signature years ago. With the last Thunderbird update, the signature font (and image) shrunk in size. I would like the signature to match the font size of the message text, like it used to. I can't find any information about that, or any explanation as to why it shrunk.

I'll be staying with a friend whose ISP is Spectrum. Spectrum claims they have no idea what settings I need to change in Thunderbird in order to go through them to get to my ISP's mail servers. I'm assuming that there ARE settings that have to be changed because a few years ago, when staying with different friends in NY, I had to call their ISP (Verizon) to find out what needed to be changed in Outlook Express' settings. I no longer recall which ones.

My goal is to get an autocorrect to work in my emails (which are in both French and GB English) so that my 'deja' becomes 'dejà' and my 'cna' becomes 'can'.

I have searched and searched and can find nothing which offers me this possibility and without it, I'll have to give up on Thunderbird and go elsewhere - it is REALLY that important for me... so any/all help would be grateful received :-)

For info, yes I have installed British English 'Language pack' and '.. Dictionary, Forked by Pinto' (which is, seemingly, the only one that works with v38.3) as well as the French versions; so yes, I get my red underlines and my spelling suggestions, however I need them to autocorrect as happens in Word or Outlook.

Please and thanks in advance to anyone who can help ! :)

When I try to send I get the following error message:

An error occurred while sending mail. The mail server responded: 5.3.4 554 5.2.0 STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied; Failed to process message due to a permanent exception with message Cannot submit message. 16.55847:69000000, 17.43559:0000000060010000000000000200000000000000, 20.521. Please check the message and try again.

I've tried numerous times. No problem receiving e-mails.

I assumed that the program had become corrupted and so tried to uninstall it through the Control Panel. However it wouldn't uninstall. So I opened Thunderbird in Program Files(x86) Uninstall folder but did not find an uninstall.exe file, only a helper.exe file.

My version is 52.2.1 running under Windows 10

106.0.2 locks up Windows Explorer (Not Responding) on my Win 7 machine as soon as it starts. After restarting Explorer, it seems to continue working. I have seen this issue reported earlier.

I think that this problem arose only with the most recent update to Thunderbird, which I installed yesterday or today (April 22). When I hit the Enter key Thunderbird automatically doublespaces, which is fine for text as it separates paragraphs. However, I also will sometimes type my name, address, and telephone number at the end of the message, using Enter for each to line, and I cannot find a way to make Thunderbird singlespace at that time. Word processors usually have a "line" option that allows for this (at least WordPerfect, which is still the best word processor, does). I'd much rather have Enter do only a single space; I can always hit it twice to double space between paragraphs (I've been doing that since I first used an electric rather than manual typewriter).

As of Sunday, Thunderbird can no longer reach my ATT server to download email. It has behaved for ten to fifteen years. Last time someone at ATT fixed it. I have been on the phone or on screen with ATT most of my waking hours since Sunday. (In the process I lost my internet, my landline, my cell connection, etc.) Everything is restored except the connection between Thunderbird and ATT. Everyone thinks changing my password will do it. Done it four times. It gets me into the ATT mail. I have replaced the password in Thunderbird settings with it to no avail. Is there anything you can think of? Not only is Thunderbird more attractive than ATT, I have thirty years of mail boxes there, a continuation from Eudora. I will appreciate your wisdom.

I am using TB 31.7.0 on a MacBook Pro running the latest version of Yosemite. I use BusyCal as my calendar software (although I think that is not relevant to the problem I am experiencing).

When people send me an email with an ICS meeting invitation attached, the attachment does not arrive. I get the email but there is no attachment. So I always have to send a reply and ask them to manually type the meeting details into an email, and then send it to me. It appears that this problem occurs when meeting invitations are generated with Outlook. (That's a guess on my part.)

I've read through the forums to try to find a solution to this problem, and I haven't been able to find it.

Any suggestions?

Hello,

Thunderbird keeps crashing. That is about all that I can tell you. It started this morning (/when I got to work I fist noticed it). I have not used any add ons. I have been submitting crash reports. Crash data avaiable on request. I uninstalled and re installed, same result; crashes immediately on start up.

Please assist.

Thank you

From the article "Microsoft OAuth Authentication and Thunderbird in 2024" there is a screenshot showing a OAuth2 option for the SMTP server setting with STARTTLS connection security. It does not appear for me. There are only the five options, as shown in the screenshot. How do enable the option to be available in the drop-down list or set it?

The available options are:

No Authentication Normal Password Encrypted Password Kerberos / GSSAPI NTLM

I am on Thunderbird version 115.12.1 (64-bit), Windows 11, version 23H2, build 22631.3737

I was looking for an item that would be a couple of years back in my history, only to discover that my history now only goes back a year and 3 months… Exactly, as of today, I don't know if that's meaningful. Does anyone have any idea what might've happened, and how I can restore the rest of my history? Thank you!

I'm on a Mac using Mojave, with Firefox version 115.8.

I have Thunderbird Version 45.8.0 where after composing a message when I click Send, the message disappears nicely from the screen and the message is off.

However on the latest version 52.1.1 (32-bit) when I do the same action, Click to Send.. the message stays on the screen for a while and I have to wait for it to disappear before I can do something else.

Is this a case of different versions or is there a tweak in the new version that I can set up in order for the Send function to behave the same way as the older version?

It is getting quite annoying sitting and looking at the screen for the message to disappear after clicking Send.

Thank you for your help.
