Thunderbird Community Forum

cannot seem to send emails to multiple people without going thru mail merge. I can no longer type the persons name in to: field and it will not autofill. I tried to go to calendar function and got a blank screen.

Can I go back to a previous version?

I always keep program icon in tray and when a new/unread email arrives, a separate yellow icon would pop up next to it... Well, after updating from 158 to 159, that new/unread icon is no longer popping up. Now I have to periodically click the main program icon to open Thunderbird and see that there's tons of new/unread mail sitting there, but that yellow tray icon never showed!

I would like to roll back to 158 but it is proving to be quite difficult.

When I launch Thunderbird via icon ( version 158), it always brings me to sign on page for Thundermail.. If Thundermail is by invitation only, how do I get back to the real TB page. I can access webmail, my account, and portal. I only see Version 156 in download folder and only have default-release and default in the profile. I have no clue then what is happening. Will bringing back an earlier version. "ABOUT" shows version 158 and nothing else.

Also, my android email & passwords have remained constant and I did not have to change anything.

I use a number of add-ons that greatly enhance Thunderbird but they keep breaking as new updates are released:

Cardbook is a very useful address book add-on, integrating with my Google address book. However a few months ago it stopped working when a Thunderbird update was automatically installed (I think it was V158). The only way of overcoming this was to revert back to the ESR (Extended Support Release). That wasn't compatible with the database that had been modified by the latest release. Fortunately I had a back-up copy of the previous database which I had to recover.

A couple of months ago a new release stopped Cardbook working. By trial and error I discovered that Cardbook had been updated for compatibility with the latest Thunderbird release so I was able to restore normal operation by updating to Thunderbird V158.

Now Thunderbird has updated to V159 and Cardbook has stopped working again. If I open Cardbook it shows the address book completely empty. The Add-on Manager doesn't flag any compatibility issues. This is disasterous for me as I am totally dependent on using Cardbook.

Lightning Calendar Tabs is another useful add-on, giving access to my Google Calendar through a icon in the task bar. However that has also stopped working under V159. The Add-on Manager shows it as being incompatible with V159.

So why does Mozilla keep releasing updates that stop add-ons from working?. Can I revert back to V158 and stop further updates?

I have had messages about EWS support being ended from 1st October from the Beonex ExQuilla Add-On which I have been using for many years.

So I installed Beonex's new Owl Add-On which supports Microsoft Graph Protocol and migrated my Email accounts. However, this just renamed my existing account with "Old" at the end and created new ones which cannot connect!

The IT provider for the Email Domain will not allow the Owl Beonex App to connect, despite the ExQuilla one being used for many years!

They have now pointed out that Thunderbird natively supports the Microsoft Graph Protocol from Release 154. BUT I am on the ESR channel (as I need stable Email handling) and the latest ESR Release is 153.4.0esr!

So when will an ESR be released with Graph Support, as Microsoft could stop me being able to receive and send Emails any day as it is now past 1st October???? - Please let me know your timeline for the next ESR with Graph support A.S.A.P.

I do not want to install a non-ESR as I see that the latest Release 157.0.1 fixed a bug with the Graph protocol and 155.0 streamlined the manual account configuration. So I want stick with stable releases!

Also, do I have to add new accounts to use Microsoft Graph, or can I just change the configuration of my existing ones?

If the former, then I guess once I am happy I have all old Emails available (as I rely on Emails going back many years!), I can delete the original Accounts from Thunderbird, including the non-working " Old" ones created by the ExQuilla to Owl migration????

Thanks

Firefox said to update to 153.4.0 esr to continue to use Google Calendar. I did and was able to recover the calendar. But the upgrade lost all my emails and folders. Previous answers for lost emails have not worked. Please give me a step by step procedure to recover my emails. Thank you

Hello, So my thunderbird updated yesterday 10/1/2026 and since then it's changed my layout and also making problems in attaching documents etc. Is there a way to revert to the last version? Or does someone have a way to fix this problem?

Ever since the last update 157 when i open a conversation it open every single tab in that conversation and i hate that, cause i have to close every one to go to another email. this stupid updating thing is for the birds. Another thing that i really liked in past versions that whatever color tag i wanted to use would color the subject line now it just does a little symbol all the way on the right side. Can i uninstall a update by chance?

On 28 August I received a blank email with just the sender and subject showing. Since then I have sporadically received completely blank emails, with no sender or subject, while others are arriving as normal. The same is happening when I open Thunderbird on my mobile, but not on my laptop which has an older version installed. It would seem that the issue is caused by update 153.1.1esr, as that was released on 28 Aug.

Can I revert to a previous version of Thunderbird or is there another way to fix this, thanks.

This morning Thunderbird asked me to update which I duly did. Once done all messages started disappearing from inbox. Eventually I found them and moved them back to inbox only for it to happen again

Have now tried 3 times, same result, every single email from Inbox keeps being moved to deleted in Local Folders

All new emails that have come in since appear for a micro second in Inbox before being moved to Deleted

This is obviously not a great situation to put it mildly and as it has never happened before and started straight after this morning's update I can only assume that the update is to blame

Any help would be greatly appreciated

When Updating from v68 to the next version up, the sub-folders I had on my 2nd email account (POP) all disappeared on the left panel but still exists on windows explorer as I can see all the files.

1. Using v68.12 with 3 Email Accounts (POP). I only download 1 email account from Network Solutions for the past 5 years. 2. Email 1 - name2.domain, Email 2 - used when Soccer Coach, Email 3 - everyday email I get downloaded from Network Solutions. 3. When I tried updating years ago, from v68.12 to the v 78s or so, all the local folders I set up under Email 1 disappeared but the folder structure remain on the hard drive. 4. If I move the files out, then in Thunderbird, right click and create the folder again called Email - BW the folder is created and blank. 5. Then I shutdown Thunderbird and move the files back and then when I go back into Thunderbird I see some of the folders. 6. If I repeat this process, I see some of the folders and I don't see other. 7. I am trying to export the data out of the Email - BW folder, but the Using IMportExport NG in v68 doesn't match up with the version with Thunberbird v153. 8. Do I need to try to load Thunderbird 78 and try to import the files? I have the data file. I have the msf file I have the folder.sbd file It just doesn't show up on the left panel? Help Please.

Your last update included a Yahoo signup splash screen. Please remove it in the next update. It is annoying and does not serve any purpose other than ccnect me to Yahoo web mail. If I wanted to use that service, I sign in for it. I am content with using Thunderbird. Or at least give me the option of removing it myself. Thanks.

Just updated to the latest version 153. No drag and drop ... message shown is 'Unspecified Error'. I made no changes when updating to this latest release. Appreciate some guidence. Thanks

Thunderbird did update while Thunderbird was running. Notice no new emails a few hours later. Icon changed to text picture and all folders showing. Received request if I wanted text icon removed? Said yes. Everything gone. Went to program file, x86 file and only file in Thunderbird visable last nigher were update logs. Now gone, everything in Mozilla maintenance folders gone.

Appdata shows 8/10 profile. Mobile email link to Thunderbird down, not receiving.

When I up dated the latest version of T.B.. when switching form the index desk top page to read the email, the page is blank EXCEPT for "SWITCH TO: EXTENSION" displayed at the top of the page

The T.B. icon is not is not displayed

From the release page of Thunderbird - https://www.thunderbird.net/en-US/thunderbird/releases/

I see 153.0 (the first release) is marked as ''esr'. But from 153.0.1, there are both esr and release. I would be great to understand the reason behind this approach.

Thanks in advance!
