Thunderbird Support Forum

Every morning when I open Thunderbird I receive the notice that "Thunderbird can't update to the latest version." but I am already running the latest version (91.9.0 as of this writing, screen capture attached).

None of the following have worked to resolve this issue yet:

• Download and install from "Download Thunderbird" link in notice.
• Uninstall and re-install from fresh download.

Any thoughts what I'm doing wrong, or what else I can try?

Thank you.

Have been trying to upgrade for quite a while now but 68.12.1 is the last version that works. Any newer TB is mostly blank, settings can't be opened, the hamburger menu on the top right doesn't work. Account manager can be opened and shows accounts correctly.

Versions I tried: 78.5.1, 78.10.2, 91.7.0. None of them work.

Remedies I attempted to no avail:

• Delete global-messages-db.sqlite
• Create a new profile
• Delete AppData\Roaming\Thunderbird completely (with backup)

I'm on Windows 10 (64bit 21H2). Downgrading to 68.12.1 restores full functionality.

My main motivation for upgrading is for a potential fix to the RSS address cannot be found bug.

Is there any chance I can get a newer version running?

Hi,

I had to update from an older version of TB to the latest due to the gmail security changes. I had an security/authentication issue that was brilliantly solved by a contributor here.

I have now realised that the update caused another problem ... my address book is empty. I have been doing much searching and reading about this and it seems that the problem is that there was a failure to convert the old .mab address file to the new .sqlite address file that the newer TB version uses. What I could not really find is the definitive answer.

I do not have any .mab.bak files in my profile folder. I have:

• abook.mab(44KB and filled with addresses)
• abook.sqlite (256KB and filled with zeros)
• history.mab (77KB and filled with addresses)
• history.sqlite (256KB and filled with zeros)

From what I read, the option open to me is to downgrade TB (all the others appear to rely on the .mab.bak files), export the address book, upgrade TB again and then import the exported address book. What I'm hoping is that someone here know a simpler way in which I can get the new TB to convert or "see" the old .mab file.

Many thanks.

Hi folks. I got a popup today advising me to upgrade Thunderbird to the newest version. I thought, "hey why not, I've been using Thunderbird for YEARS, I like it it's great"....so I did I can no longer connect either of my gmail accounts or my icloud account. Is this a known problem with the upgrade? If I wait a bit will "it fix itself"?

Any ideas?

Thanks!

Mozilla says it can't upgrade existing Thunderbird version and wants me to replace it with new version that I must download, as if from scratch.

If I do that, what happens to my settings vis-a-vis Gmail, which is where I fetch my mail?

Can some of you share experiences you've had using thunderbird with office 365? I may migrate a small business' email to office 365. I know 365 + thunderbird is possible as long as imap is enabled and that wouldn't be an issue. Mainly I would like to know how smooth it has gone for those that have tried it. I don't think the people at this org use the calendar feature of thunderbird. They would need email and contacts. I've used thunderbird + gmail many times and that combination works well.

I bought a new laptop because the old one died. Now I tried to transfer my TB data into the new computer. I managed to do it BUT... only one of my two MAIN folder data is there.

Last time I needed to do that when my laptop died it worked. Now despite me using the EXACT profile path/name (eg, C:\Users\XXX\AppData\Roaming\Thunderbird\Profiles\XXX) in TB's local directory at my new computer only one MAIN folder's data is present.

Does anyone know how to solve this issue?

Thank you!

I have re-installed Windows 10, and Thunderbird. My address book information and messages are missing. Can these be found somewhere and saved.

thanks

I'm trying to help an elderly friend move from Eudora OSE to Thunderbird. I found this closed thread on the forum - and I want to know 'how to back up the Eudora OSE Profile' - or any other help you can give re migrating from Eudora OSE to Thunderbird. (She has thousands of old emails.)

The tech person said,

"May I suggest, back up your OSE Profile, and give it a try.

And the other replied: "I took the tech's suggestion Backed up Euroda files and simply installed Thunderbird VOILA ! When I launched Thunderbird it simply accessed the same files and file structure (and settinge/etc) as Eudora and I didn't have to do anything ... awesome !"

I have used Eudora for years, about 20 or more. Now I find myself with a dilemma. A secure email program I signed up for must have ports assigned to incoming and outgoing servers. Alas, not possible with Eudora, but possible with Thunderbird.

However, after reading several of the threads of migrating to Thunderbird from Eudora, it appears to be problematic--new addons, missing mailboxes, etc. It's hard to tell whether that's the norm or the exception. One of the threads I read was https://support.mozilla.org/en-US/questions/1228297 "Migrate Eudora mail to Thunderbird mail", which suggests starting with Thunderbird 17.0. That thread is from 3-1/2 years ago. Is this still the best way to migrate? Or is one of the Thunderbird migration tools a better and safer option.

I have literally thousands of saved emails and dozens of separate mailboxes and I don't want to lose them.

Really annoying, looked through all the threads, tried the various "fixes" nothing works. It should be possible for the Thunderbird app to be in light mode, while the rest of the system is set to Dark.

I have used Thunderbird for quite some time. It recently crashed and had to be reloaded. When I did the install I checked the box for it to not be the default browser, it still loaded and became default. I deinstalled and installed several times with the same result. There is something Im missing. Any ideas?

I made the mistake up upgrading to the latest beta, not realizing it would convert my datafile to a different format and you can't go backward. I have done recovery over the years, but all the help refers to the old formats. Opening TB just causes it to hang. I have a large thunderbird file with a lot of files. I thought maybe a folder that I use a lot was too large so I tried splitting it in 2 but it has been unable to sync those since I moved them. Instead my whole computer hung and it turned out 400+MB was being taken by a folder which gets created when a folder can't finish compressing, but I had no choice but to delete that because my computer wouldn't function. In the past when a folder wasn't working right I would delete the folder index file and it would rebuilt the index and re-built that folder. Now all of my folders have mozmsgs but only some have sbd's. And the new folder isn't even there, although it's showing in my TB app when it opens.

I need to know what types of files I should delete in order to have my folders re-sync to the server.

Thanks!

Hi Team, I love TB and have been using it for a very long time. Until recently I was able to access my profile from both windows 7 and Ubuntu 20.04. The current versions are 91.9 on Ubuntu and 78.4.3 on Windows 7. I have 2 users (my wife and I) and somehow seem to have got into a real mess. My wife is asked all the "new install" account stuff from either windows or ubuntu. For myself I can open my profile successfully (bizarrely) with 91.9 on ubuntu but hit the install issue on windows 7. I have in the past messed around with profiles.ini with some success, but so far I havent been able to massage my configs so that I and my wife can access our old profiles.

I have looked though some of the existing issues but am hoping some kind soul will explain to me: a) can I use latest code to access the same profile b) how to configure the magic, please?

regards, Paul

Many years ago, I had two computers receiving email. Both received a copy of each email.

I am attempting a move from my old Thunderbird (38.5.0 in Windows XP) to a new 98.9.1 in Linux Cinnamon Mint. I sent an email to the mailbox. It was received only by the new Tb. I shut down Tb and restarted it. I sent a second email. It was received only by my old Tb.

The server settings are: Check at startup, Check every 10 minutes, Automatically download, Leave messages on server, Until I delete them."

I can find no option to allow the email to be downloaded by two Linux versions of Thunderbird, though surely that must be routine for those who receive their email both on a computer and phone. I need a POP solution, since I can be away from either version of Tb for some time.

Help, please!

I let Thunderbord fill out the first forms page, and the encrypted P/W is green. I also attempted to populate the "att.net" settings, tested it, and the P/W is green. After doing all this, I do NOT see a "Create Account" field. Not sure what to do now.
