When I downloaded and sync Gmail to thunderbird, I encountered the following issues:

1. The number of emails on ALL MAIL folder is not the same as that in my Gmail. Thunderbird has more than 800 emails compared to my Gmail.

2. When I randomly check my emails through the search function, the emails can not be found on the location it states thy are. Ex. location=all mail , but when I search ALL mail , the email in not there.

3. SAME Email but the timestamp in Thunderbird is 1 minute less than the time stamp in the Gmail. Ex. In Gmail time stamp is 11:04 am , in thunderbird it is 11:03am

4. Also can I change the Date Pattern in Thunderbird from DD/MM/YYYY to MM/DD/YYYY?

Thank you!

Hi, I have two Win10 computers both with Thunderbird installed. Each computer has a different email account that Thunderbird controls. While they are separate accounts (i.e. different user names) the mail service (domain name) is the same. How can I move both accounts on to a new Win11 computer using Thunderbird? I've read the instructions on how to move Thunderbird from an old computer to a new computer but I wonder if I use those instructions I will overwrite one of the accounts. thanks

Hello all,

I have several machines we use thunderbird and gmail connection on.

We can only get the accounts to link if the authorizations is set to "normal password"

From what I have read on the forum, we will need to change the authentication to oAuth2 for our accounts to work after May 30th.

Following the steps to do so, and authenticating (and allowing access) in the browser, I am unable to send/receive on the thunderbird side. Switch it back to normal password and it will again work properly.

Is there anything I missed here? Not understanding why we cannot get Oauth2 to work.

Current Settings

IMAP enabled in gmail Cookies allowed in thunderbird Less secure apps off in gmail (trying to get ahead of this before May) private/public windows defender firewall off

Thank you

I am using Mozilla Firefox on Samsung Galaxy A5 phone (Android version 4.4.4) since 2016. I last used Firefox on my phone yesterday. Today, when I wanted to browse internet, I noticed that Mozilla Firefox app has been removed from my phone. When I visited Google Play Store, the app was unavailable in search. Since the app has has vanished from phone, I tried to open the download link on Mozilla.org website in Chrome, it is not working (https://app.adjust.com/2uo1qc?redirect=https%3A%2F%2Fplay.google.com%2Fstore%2Fapps%2Fdetails%3Fid%3Dorg.mozilla.firefox&campaign=www.mozilla.org&adgroup=mobile-android-page) I am in a fix! Please provide resolution on priority.

Why is firefox automatically downloading strange files I've never seen before? (MEUIVFJ-.htm and 3tHMwYhc) They look a little untrustworthy. My download dropdown suddenly showed me that one had been downloaded, and then a while later the other one was downloaded. Are these actual Mozilla files? Or are they some kind of scam/trojan/spyware? I just realized that two were downloaded last month as well.

Came out of Win10 mail, moved to Thunderbird. (Good decision). After much screaming and kicking I managed to get my address book info out to a text file, formatted as CSV. Very simple, 3 fields: firstname,lastname,emailname@emailaddrs comma delimited.

Used the Import function, aligned 3 fields with the input data, done. It created a file called "email contacts". All of the addresses came in. Then it got kind of strange. When I open the that file it only shows 2 columns. Col1 is "NAME", Col2 is "EMAIL" Col2 is correct but Col1 shows the emailname only snipped off of the full email address. If I open any entry in the address book with the EDIT button, the first name and last name are there, so the import worked. So the question is: How do I get the top level of the address book to display the firstname, lastname? Did I do something wrong on the import? I can't seem to find any way to add columns or re-arrange the display. The "select columns to display" menu doesn't have any choice that I recognize. I can re-format the source file any way I need to, is there a better structure for import? Advise needed.

I need to install a mailbox on a new machine. I have got as far as the second screen on manual configuration, ie the one which starts with IMAP etc but I can't remember what to enter in some of the boxes. I don't know the port number (or even what that means) and on the host name for the outgoing server I think it began with relay but can't remember the rest. My ISP is refusing to help so please can you? JW

I just downloaded the latest version of firefox. When I tried opening it the message said it is not compatible with Max OSX 10.11. I now need to download a later version of firefox. Which version is compatible with Mac OSX 10.11? thank you!

Hi, I'm struggling to access my address book from my old PC, which died.

The hard drive still works so I have been able to access the old profiles (why are there 2?) and replaced in the install of this new machine:

"Your Thunderbird profile cannot be loaded. It may be missing or inaccessible."

So.. that didn't work then. I cannot even load Thunderbird now, just gives that message.

The original machine was Windows 7. I cannot run it, so cannot tell you what version of Tbird it was but it was reasonably up to date. Current install is the very latest.

So... what to do next? I can put a copy of the profile back... OK, can start Tbird again, but how to access the old profile with many years of address book?

Manually copying the profile files into the profile folder doesn't seem to work, even after removing the (new) originals. Rather than using the old ones it's just saying it can't find the newer ones, so I presume there's some way of telling it to use those older ones?

Thanks!

I got an email to update to version 100, and downloaded and installed, but now I have no bookmarks or anything else, just a blank version. Please help me! Thankyou!!

I followed [guide] to move my Thunderbird profile from my old computer with Windows 10 to my new computer with Windows 11, but it is showing up as an empty window with no emails or folders/accounts. It also doesn't show my tabs/session. If I try to write a message, there is no "from" email address. I do get email notifications though, and I saw in Gmail that my forwarding filter worked as well. There is no error message or anything. I tried starting it in Troubleshoot Mode, but the same thing happens, except that the background color is different. I attached a screenshot of it in Troubleshoot Mode. Could this problem be due to Windows 11? Is there anything I can do to fix it?

Hi Support,

Trying to migrate from Thunderbird 91.8 on an iMac with iOS 10.13 to a MAC Mini M1 with iOS 12.3.

Following all the instructions, but every time when I copy the old profile to the new, T-bird will start with all of the accounts in the proper order, When I go to download mail, it asks for security certificates for every account and will nor download email.

When I exit Thunderbird and restart, about half the email accounts show up, The other inboxes are no longer marked as "Favorite Folder" and none of the Sent, Trash, or SPAM folders appear.

I am out of ideas. My next step is to load a clean T-bird 91.9 and manually move al 40 email accounts and I really do not want to do that.

Anyone with a solution?
