Thunderbird ஆதரவு மன்றம்

When I upgraded from MacOS Ventura to MacOS Sonoma, Thunderbird stopped working. Getting it to work the first time required me to use Apple's 2 Step Verification process to create an app-specific password. After the MacOS upgrade, that process was no longer available. Apple switched to 2 Factor Authentication, which is apparently different and incompatible with 2sv. The other websites and applications on my iMac have already switched to 2fa, and I'm not sure I can have both methods active on the same computer (but I've asked, Apple, anyway).

Is there a recent change in Thunderbird that would allow me to use 2fa instead of 2sv to access Thunderbird?

I have many years worth of emails in Thunderbird that I can no longer access. I can see the directory structure, and some of the email lists, but not the content.

Thanks for the help!

Thunderbird update 115.3.1 self installed now nothing works.

When I first opened program after update and tried to retrieve mail for one account (of5) got a window telling me password not accepted by pop server (at zoho.com) and asking if i wished to enter a new one. Said no and went to passwords in config to check if they had transferred properly. They had.

Tried again to download messages with same results (password not accepted)and clicked to enter new one. Instead window popped up for next account telling me password not accepted by server and did I want to enter a new one. Same results for every account in order without ever letting me access one. Rebooted - no change.

Downloaded copy from mozilla and re-installed thinking it may reconfigure what was wrong. No luck. Now when I try to retrieve messages I don't even get password not accepted only "done" in bottom left corner where it usually shows download happening.

I have used Thunderbird practically since it came out and have installed configured and transferred accounts across many computers and never had any problem like this!

My thunderbird just upgraded to 115.2.2 (32-bit) - my windows is 64-bit - but I can't read the preview window or emails. Everything is in a gigantic font so I see only 2 lines at a time in both the main email edit screen and the preview screen. I tried changing it to Calibri 12 in Settings (it was Calibri 17) but that makes no difference. I also don't like that I have to go through File menu now to get messages for just one account. Is there a way to downgrade back to my old version? I guess that would be 115.2.1. Thank you!

Thunderbird layout - how do i enlarge the classic view current message pane window? it's too short/compressed, and i can only drag it up a little, then it stops. In the prior TB versions, I only saw the last 3 or 4 messages in the upper message list portion of the classic view layout. Now I'm seeing almost 10 messages in my messages list. Meanwhile, the actual current message viewing pane is now horizontally compressed so that the ratio of message list to message view is closer to 40% message list, 60% actual message text plus the header info. I have tried click and drag the upper border of the current message being viewed, towards the top of the screen, but it stops, and still shows me 10 most recent messages in my list, which is really useless. I only need to see the last 3 or 4. The rest of the viewing pane should be more of the text area of the current message being viewed. Is there a "config editor" tweak to reduce the messages list to 3 or 4 messages, and increase the actual current message viewing area? Or some other fix for this?

Hi, I stupidly 'upgraded' from V102 to V115, which I immediately disliked. I managed to re-install V102, but it then said the profile was for a newer version. I had a backup from a few weeks ago, and copied all the top-level files over. So I got all my setup bacvk and all seemsed fine, but have just seen that my address book is messed up.

I had lots of important 'contact lists' (about 10), they have all disappeared. I only see "Outlook Express..." (imported ages ago) and "Collected Addresses", the main section, and the sub-lists are all missing, and I have lost years of addresses for my business.

I have the abook.sqlite backed up on 13th Sept, but can't open or use it to check what's in there. I tried importing, but got as 'fail'

Thunderbird 115 forcefully migrated my older profile and did NOT leave a way to go back?

That is NOT the way to do this.

You need create a NEW profile for the NEW version and LEAVE THE OLD PROFILE ALONE!

You must also have an alert, and explain the process, transparently giving the owner of decades of e-mail the opportunity to safely upgrade AND have the opportunity migrate back if they so desire.

How DARE Mozilla treat users and their data so casually.

This is NOT the way to do this.

Currently FURIOUS that this trusted tool has left me NO way to downgrade back to 112 except to rebuild my profile (and all the various e-mail accounts) from fucking scratch.

Hi, I run TB on 2 machines. On one (running Win10) Supernova downloaded automatically, odd as I thought you had to opt in to get it. (The other running Win11 is still on v102). No problem as it looks good. (I'll make any suggestions separately.) But I'm concerned about migration as I have a lot of messages, both archived and in live folders. Judging by some forum responses version 102 should still be lurking in the background. Is that right? And if so what's the migration plan once Supernova is out of beta? And as I was about to move storage location from C: to D: for space issues, is it best to hold off until Supernova is fully live?

Thunderbird is completely unusable in the latest release. Attempting to set up a gmail based account results in

"Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to 192.168.1.250. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details."

That's it. No options, no explanation, no KB articles, nothing. It just doesn't work. But why is Thunderbird trying to open a web connection to my local machine? If it's trying to talk to itself, why can't it? This is clearly an issue with trying to authenticate to Google as it happens after auth, but come on, this is a given requirement these days. If your app doesn't work out of the box (MacOS 13 btw), it may as well not exist for the OS, so this is very confusing.

Trying out older versions was a real comedy of failures as well. Too old and it's just a disaster. Too new and it just self updated to 115 again which doesn't work. So kinda seems like this is not a functional app anymore, at least not on Mac. Baffling. I guess it can only be used with legacy style email systems.

After the automatic upgrade to 115.2.2, I have lost access to all my folders, emails and calendar entries. But I can still see my addresses by using Tools/Address Book, and my filters by using Tools/Message Filters.

When I started Thunderbird for the first time on 115.2.2 I got to the usual message page which had all the tabs of the "open" emails I had when I last closed Thunderbird. But there was no sign of my folders and I couldn't get to any other messages (See first screenshot). I also had a second occurrence of Thunderbird running (I could have hit the icon a second time) that didn't show the tabs I had on the first screen. (No screen shot)

On a previous post here https://support.mozilla.org/en-US/questions/1424153 it was suggested that I try Troubleshoot mode. That made no difference and at that time I had no folders showing, and just two tabs. I suspect after that I deleted the tabs.

Now I get a completely blank page in what is usually the message/folder area. Also the button for the address book above the message pane has now gone disappeared (Second screen shot), and I can find no way of accessing my previous (10years+ of messages).

It looks to me as if something is wrong in the profile.

Where do I go from here?

Following an automatic update the other day, everything in Thunderbird is oversized. There are in fact some things I can no longer see at all! The program has become very difficult to us to read/write emails. See the image below, a full-screen capture showing the problem . There must be a line to edit in the fonfig file to make the display look normal again. Please help me find that line!! I am visually impaired, and life is difficult enough already! tnx, Paul pgschreier@swissonline.ch

Hi, I got the (unwanted) Update on Thunderbird 115.2.2 (64-Bit).

I use a notebook 14" with full HD. With the new update I have trouble reading the texts in Thunderbird, mail, etc. because of the font size & layout. I wear glasses and I'm 50+ ......

HOW CAN I GET BACK THE OLD LAYOUT AND TEXT SIZE ??

I'm really pissed :(

Thanks, Martin

Thunderbird updated on its own without notice to version 115. When I tried to open Thunderbird, I received login errors for each account and all my messages were missing. I tried uninstalling it and reinstalling version 102 and now it says that my profile is incompatible. My POP account and local messages are all gone. I don't want version 115. It is clearly incompatible with my computer and accounts.

I just upgraded to Mac's latest OS 14.0 (Sonoma.) Thunderbird will not load. When I run the application I get a beachball and an "application) is not responding" message. I have tried rebooting and all the "typical fixes.)

Is there an update coming? Something that I can delete to make Thunderbird work?

I recently noticed that Thunderbird quietly updated itself from 102.15.1 to 115.3.1 for me today. (I'm on Win 10)

After this, none of the emails in my imap.gmail.com mail account are viewable: My 'Inbox' shows 2 email accounts underneath and selecting the gmail one shows a big list of messages but opening (double-clicking) any of them just opens a new tab that remains entirely empty.

Emails for the other Inbox account do correctly show messages in a new tab when opening, as things were previously.

The Tools > Developer Tools > Error Console shows the following errors (after having first cleared the log and then restarted Tb) - NotFoundError: No such JSWindowActor 'DevToolsFrame' Assert failed: Calendar manager initialised calendars before loadCalendarComponent ran on the first 3pane window. This should not happen.

calUtils.jsm:127:15

NotFoundError: No such JSWindowActor 'DevToolsFrame'

I found recent posts for similar sounding issues (but not quite the same). One suggested deleting 'folderCache.json', 'session.json', and 'xulstore.json' files from my thunderbird profile folder and restarting. I tried and it had no noticeable effect.

I can't be sure whether it was there before but after the problem update, I notice I have 2 instances of my gmail address showing under the 'Sent' tray/group. Under sent it lists 2 x my gmail.com account and my other account. Again, the other account's sent mails can be viewed just fine as before but the first '...@gmail.com' account list most (perhaps all) of my sent emails, but opening any of them just brings up a totally blank new tab again.

Interestingly, however, the other (new?) duplicate '...@gmail.com' under the Sent group also shows a big list of sent emails and this one does correctly show all messages when viewing any in a new tab. The properties of both of these identical-looking 'sent' mailboxes ('x'-ing out my email) are - 1st - Location: imap://xxxxxxxxx%40gmail.com@imap.gmail.com/Sent Showing 267 sent messages Doesn't work. Viewing any of the messages just shows a blank tab. 2nd - Location: imap://xxxxxxxxx%40gmail.com@imap.gmail.com/%5BGmail%5D/Sent%20Mail Showing 283 sent messages Works. Viewing any of these opens a tab that correctly shows the message. To my knowledge, I've not added the second almost identical 'sent' gmail account.

The location of the newly broken @gmail.com Inbox is - Location: imap://xxxxxxxxxx%40gmail.com@imap.gmail.com/INBOX

The fact that one of the gmail.com sent lists/view works and the other doesn't suggests something might be wrong with the 1st 'location' format. I've not touched either for as long as I can remember. Could the upgrade have diddled the 'location' in such a way as to cause this behaviour or also duplicated a subtly different gmail.com 'Sent' folder?

The main Tools > Account Settings does not appear to have a field that directly specified any of the 'Inbox' or 'Sent' Location fields that I can see; it just list my 2 email accounts, with my now broken gmail.com one listed first, with server settings - - Type: IMAP mail server - Server Name: imap.gmail.com - User Name: xxxxxxxxxx@gmail.com - Port: 993 - Connection security: SSL/TLS - Authentication method: OAuth2

Can anyone explain where the subtly different 'Sent' gmail entries might have come from and whether either of the 'Location' fields look invalid? Also, since my gmail Inbox 'Location' looks to have a similar format of that of the broken 'Sent' item/folder, does anyone know whether it is invalid and can be fixed with a different location field?

Somehow, Thunderbird updated to a new version. I didn't download or install a new version. I just closed and reopened it and it updated. When I tried to roll back to the new version, I lost all of my emails and addresses! I literally had tons of business emails and contacts and now they are gone. Thunderbird is treating this like a brand new install and I am having to set up all of my accounts all over again! Is there some way to get all of my stuff back? Or has the new install/rollback somehow written over all of my previous data?
