When I open Write mode the font is too small and it doesn't change when I change the size to Large or the larger ones in Settings/Composition/HTML Style/Font/Size.

Thunderbird 140.7.1esr (64-bit) Windows 10 Home.

Thanks for your help,

Frank

Does TBird support plus addressing?

Scenario: I want to reply to email sent "To: markfilipak+joe@...". To do that successfully, in the "Write" dialog, I have to click on "From", scroll down to "Customize From Address...", click it, and add "+joe". (There is a menu alternative: "Options","Customize From Address...".)

If I forget to do that, then my reply does not have "+joe"; it goes out "From: markfilipak@...".

The Issue: When Joe replies to _that_ message, it does not have "+joe", so Joe's reply is trashed. (It's trashed because a filter I wrote automatically deletes messages that do not have "To: markfilipak+<something>@..." in the header.

The sensible way to handle plus addressing is for TBird to recognize plus addressing and to automatically make my "From" header from Joe's "To" header. That way, "+joe" will always be there.

Is there a way to do that?

Thanks Folks! -- Mark.

For some time now, TB (147.0.1 (64-bit)) has been VERY slow loading, the first thing in the morning. If I close it and re-open, it opens at the normal--and desirable!--speed. Any thoughts? Regards, Dave

Every since updating to Thunderbird 147.0.1, I have noticed that every time I start Thunderbird, it creates a directory called "Thunderbird" in my home directory! This didn't happen before the update and I have a '.thunderbird' directory in my home already! I had a search in the settings for the term "directory" but did not find anything that seemed related. But it seems to be caused by some new setting that has become activated with the update.

I am on an Arch GNU/Linux operating system, if any further information is necessary to help debug this, please let me know. Thanks a lot in advance :-).

Hi. I recently had to change email providers and at first chose Proton but had to change again for reasons. Before I moved to proton, I shifted a whack of email to local folders on the advice of someone. I backed up my profile folder before making the move to proton, but didn't realise (I know, 'duh') that local folders didn't move. It wasn't untill I moved again that the local folders in the new install were empty.

All 3 accounts—original, proton & new—had the same email account name/domain but I want to know how I could create another instance of it to port all my old email from the original service—which has all the email still in their original folders (not local) so I have them 'non-local' again and can go through and organize them anew.

The alternative is to connect the local folders to this new instance but I'd rather the first scenario.

I'll only still have access to all 3 providers for another couple of weeks so this is feeling urgent.

Any help/suggestions most welcome. Thanks!

Bonjour à tous et toutes, Je ne dois pas être le seul à demander ou redemander, cette question auquelle je ne trouve pas une seule solution éventuellement proposée, qui règle le souci Explication J'ai donc thunderbird avec 5 comptes de mails d'opérateurs différents dont, l'emmerdeur FREE En effet, en plus du logiciel, j'ai un vpn sur mon pc et mon mobile pour le travail et autres Si par malheur j'interroge mon mail free avec mon vpn actif soit sur pc ou sur le mobile, tout se passe correctement mais trés rapidement dans la nuit cet emmerdeur de free bloque mon mail, annule le mot de passe car il a détecté le MAL !!! et bloque toutAlors les ennuis commencent avec thunderbird Je m'arrache les cheveux, car à peine déclencher evidemment il interroge free et là !! bim !!! refusé ! et c'est le caca !! la fenêtre de connexion pour free, n'arrête pas de revenir bloquant tout, tout !! tant qu'il n'aura pas un bon m d passe ! et je ne veux pas supprimer le compte mail pour débloquer, car cela fou la merde avec tous mes dossiers de mails free enregistrés dans thunderbird , et c'est pénible de tout remettre et relancer et reconfigurer comme on le souhaite Je voudrais savoir pour les ingénieurs et leurs grandes antennes de thunderbird, ne font rien pour ce souci a priori réccurent et connu On m'a dit de décocher des cases pour essayer de "sauter" free mais aucune solution ne fonctionne C'est une vraie plaie à l'appréciation de ce logiciel. Alors svp une vraie réponse de pro claire façon tuto et fonctionnelle svp pitié !!

I'm not sure if I'm doing something wrong but in the last 3-6 months sending email from TB using Yahoo SMTP server is very slow and fails completely one out of three times. If I keep trying it eventually works without me having to make any changes.

My SMTP configuration is using port 465, OAuth2, SSL/TLS. Is that wrong?

I've been using Yahoo for a very long time without any problems but changing to OAuth2 seems to have slowed things down.

I have a fast internet connection and nothing else is causing any issues.

(Login to server imap.videotron.ca with username (username....)failed) shows up continually and I don't know how to make it stop. It is stopping me from sending or opening emails. Can someone please give me a solution. I've just switched it to a new computer and I am getting the same messages on both computers. Thanks

I can't login to one of my email addresses. It says login to server with username failed. I tried all of the suggestions (using a pop server for example) and none of them seem to work. Please help.

Since a few weeks ago every time I try to drag an email from the inbox to a folder (I'm not ever trying to drag it out of Thunderbird), if I falter with the mouse or try to drag it a second time I get dialog box asking if I want to replace a file that already exists in the "mozDraggedFiles" folder. e.g.:

 CONFIRM
 /var/folders/4g/sjfdskjgdsklfi098ds09jsejre/T/mozDraggedFiles/<subject_of_email>.eml Already exists do you want to replace it? Y/N

Clearly a temp folder for stored copies of emails before they get moved/copied somewhere.

There's a similar bug reported here: https://bugzilla.mozilla.org/show_bug.cgi?id=1983616

Which links to another couple of bugs, but all are talking about dragging files to desktop or other location but not about dragging them within the program.

Presumably once a dragged email reaches it's destination the copy in the mozDraggedFiels folder ought to be cleared right? I wonder why that has changed recently, I'm pretty sure I haven't had this issue before.

Also to make matters worse when the dialog box comes up, it is only displayed locally to the machine to screens connected directly to it and if I am remoting in with share screen or something like jump desktop the machine essentially hangs/disconnects until the dialog box is closed!

Anyone else getting this ?

I'm on OSX 15.1 and Thunderbird143.0.1 (aarch64) R.

thunderbird Is working fine, but this message crops up every few minutes, and requires 4 - 8 Cancel clicks. I've tried "Open anyway", I've deleted and reinstalled the app several times, and tried the terminal command "xattr - cr" and dragging the app into the window. Is there a proper fix for this. V. grateful for any solution. TIA Brian

Hello, since friday, 6.2. thunderbird does not launch new (and also not completely all older) Emails anymore. So I can't see all my recieved and send E-Mails. In all my 3 Mail-Accounts froms different providers it does not work anymore, without changing anything from my side I know. But from my handy, where I use google-Mail, it works.

I already checked synchronization settings and repaired the E-Mail-folders.

So, are there any technical defects or problems with thunderbird, an update for instance that caused trouble for instance? And what can I do, to make it work again? Atherwise I would have to quit thunderbird and change my Host.

Looking forward to your response and already thanks for support, all the best, M.

Problem with recurring events in the caldav (external) calendar. If you delete one instance of an event (today), events for previous days are automatically created.

Thunderbird ver. 140.7

The Hilton hotel reservation produces the following .ics file (with some edits for privacy), which fails on import. Deleting lines like the second block will import correctly. I can make this edit when needed, so this is more of a bug report than a question. I have not tried to narrow it down more, this is something I do once every couple of months.

Hello,

Need To Know:

I have used Thunderbird (TBird) for many years. Recently, I moved TBird data from a Dell Inspiron 530 Win 7, to Alien Arora 1250. Unfortunately, the passwords would not go, so I copy and pasted the data for 10 email addresses. All worked well, until 5 days ago when I could not log into the ISP.

Since then, 12 ISP tech support people gave me 12 different was to fix the login problem. The 'logging in' kept trying to login. The only way to stop it is to close TB and restart it. The same happens with all 10 accounts - can't login.

I followed instructions to the letter and nothing worked. Later, a tech at ISP said they have had a lot of complaints from people with Tbird and said it's Mozilla's fault. They all said they don't support Thunderbird. They only support webmail. One even suggested I delete all my cookies. Of course I'm not going to do that.

You would not believe the amount of crazy ideas I was given.

Here is the core problem:

I used both Pop and IMAP depending on the email account. TBird was great with POP and IMAP either.

I changed all the passwords as instructed. I followed the Step-x-Step settings on the ISP web site

The ISP, Rogers, took over Shaw. Rogers, I'm told, dropped support for 3rd party email clients and requires customers to create a new email on their Webmail host. Webmail is WEBmail because it is not Email.

Testing Out TBird:

1. On the old Win 7 TBird (Ver. 68.1.1 (32-bit)) Email works with both POP and IMAP settings.
2. On the new Rig, Tbird (V. 147.0 (64-bit)) worked for a while.

What Happens: -- Due to the issues, I set Tbird to not:, -- Check for new messages at startup -- Check for new messages every -- Automatically download new messages -- Fetch headers only

The two ISP are Rogers Rogers and Shaw <--- just redirects to Rogers. But webmail.shaw.ca still works.

My Rig with the issues: Alienware Aurora Desktop 1250 Intel i9 Ultra Nvidia RTS 5080 Memory 32 GB DDR5 Storage 2 TB SSD + 2Tb HDD Thunderbird Version-147.0 (64-bit)

Is the ISP correct, that Thunderbird may be the core problem?

Thanks for your volunteering - where would we be without you, ~r

Add outlook email account in Thunderbird app on Macbook does not strictly go through microsoft 2-step verification process. In stead, microsoft verification window flashes away instantly and Thunderbird window takes over. Although OAut2 is specified, the set up is not right. Sending email from outlook account takes about one minutes. Sometimes if it takes longer time, sending email will fail.

I have been using ThunderBird on Linux Mint for some time now. I am using Outlook.com for emails, calendar and contacts and I sync with another laptop and mobile phone. All fine until a few days ago when I noticed calendar events were not syncing with my phone. I found one calendar event in ThunderBird had an error when I manually synced with TbSync. The error report did not say anything specific. I deleted this calendar event and TbSync ran successfully uploading 2 events that it had not uploaded due to the calendar sync error. I then wanted to manually recreate this calendar event in ThunderBird. When I clicked on "New Event", the Calendar New Event pop-up window did not appear. When I minimised the ThunderBird window, the New Events was not behind it. The ThunderBird icon pinned to the panel had a "2" in the corner. When I hovered over the ThunderBird icon in the panel, it showed both the ThunderBird window and New Event window preview. When I selected the New Event preview window in the panel, it still did not become visible. All I could do with with New Event preview window in the panel was click in the 'X' to close it. I checked for Lightning Calendar Tab add-on updates. It was up to date. I check the settings. All OK. I disabled and enabled this add-on. Still not working. My Windows habits made me shutdown and restart my device. Still Not working. When I checked the other ThunderBird functions, New Event pop-up windows appeared for Emails and Contacts but not Tasks which had the same symptoms as the Calendar.
