I used to use Foxmail as my email client. When writing emails with oversized images, I could right-click the image and select the "Auto resize it to proper size" option to make the image easier to read. However, I can't find the same function in Thunderbird. Do I need to use an extension, or is there another way? Can someone please help me? It's really frustrating.

After first pressing "Mark" (K), the shortcut keys for "Mark as Junk" (S) and "Star" (S) are the same. Previously, the shortcut key for "Mark as Junk" was (J). Please make the necessary corrections.

最初に「マークを付ける」（K)を押してから、「迷惑マークを付ける」（S）と「スターを付ける」（S)のショートカットキーが同じです。 以前は迷惑マークのショートカットキーは（J)でした。

修正願います。

Hello! I don't understand what's happening with the folders... I've been using Mozilla Thunderbird with this setup for a long time. I had a RedMine folder and a filter configured to move messages from the Inbox to it. But recently, the filter stopped working because it couldn't find the folder on the server, even though I could see it in the folder tree and in the web version of Mail. I deleted the folder and created it again. I enabled the filter, and the messages moved, but they weren't moved to the new folder, but to the one in the Trash, and the new one remained empty. Yes, I restarted Thunderbird, and messages started moving to the new folder, but I don't understand why this happened in the first place—why did I have to delete and recreate the folder?

Установив цветовую метку и после обновить, то данные пометки сбрасываются и сообщения снова становятся белыми Проблема возникла примерно после 12 часов по МСК и продолжается до сих пор

Можно воспользоваться кнопкой "Получить сообщения", после ее нажатия также слетает цветовая метка (скрин)

I had to recently change my password on my shaw email account. Now thunderbird won't download my emails. I changed the password in the account settings to match the shaw email account password but I keep getting an error message: "Host contacted, sending login information..." and then after a long delay the error message reads "Login to server pop.shaw.ca with username ... failed". Any idea what I'm doing wrong by simply changing the password? I think this happened before and some wonderful human on this forum told me I had to put something before the password or click/unclick a particular box, but I can't find that old answer to my previous question. Thanks in advance for any help someone can offer!

I want to configure an automatic response to emails that have been forwarded to me from a particular address. I have created a template for the response and it is saved in the Templates folder. I then attempted to create a Filter Rule to send the response. I believe there should be a Reply with Template option in the Perform these action pull-down, but there isn't. I've attached a screen shot to illustrate this.

I'm using Thunderbird 154.0 and Windows 11. Is there a new way of achieving my objective?

I have a smartcard with email signature and encryption S/MIME certificates. I recently updated the signature and encryption certificates on my card and was having issues getting TB to read the encryption certificate. Both the signature and the encryption certificates check out fine with the certificate issuer (IdentTrust), can be read by Windows, Edge, and Firefox Certificate Managers, and works fine for authentication to websites. I am wondering if I accidentally deleted the encryption certificate in the TB Certificate Manager, as the signature certificate (having same issue date and email address) is visible but the encryption certificate is not found. To see if I could restore access I have tried replacing existing profile files having dates prior to the new certificates for:

cert9.db
content-prefs.sqlite 
key4.db
permissions.sqlite
pkcs11.txt
prefs.js
SiteSecurityServiceState.bin

This restored my settings for my previous (now expired) certificates but still does not allow me to view the encryption certificate in Certificate Manager. I also tried removing the logins.json and logins-backup.json files which had no effect on ability to view the encryption certificate, and tried adding the certificate ID .

I'm hoping someone could explain what the TB Certificate Manager does when when accessing and deleting a certificate from a smartcard (it can't electronically delete it without the middleware - in this case ActivClient, and the missing certificate still remains as other apps can still access the certificate in question). I surmise that the name must be stored somewhere, and hopefully by editing the appropriate preference setting I can restore access.

I tested out the incoming and outgoing security server and they both are successful at SSL/TLS but I still cannot send email. Is there anything else I should check?

I bought a new pc with windows 11 and everything is fine except that I installed thunderbird via microsoft store and when I gave it my email address, I could see my emails but it hasn't created a profile. Therefore when a try to view the profile it says user.../appdata/roaming/thunderbird/profiles... doesn't exist. I am logged on as an administrator. Should I uninstall then install from the mozilla website directly?

This past week I started having a problem accessing URL's embedded in my emails from the Thunderbird interface. When clicking on the URL reference, nothing happens. I have not changed anything in my settings recently. Running Windows 7. I know my email server is working since this works when using my AT&T mail handler. I did have an issue with a Trojan virus that was cleared up with Malware program (i hope). I checked all the parameters of my mail handler and saw nothing that might cause this problem.

Have used Thunderbird for years and never had this issue before. Just upgraded to Thunderbird 115.18.0 esr and my calendar is now blank. Did the upgrade erase the data or is a pointer off somewhere? Can I get my calendar back?

How to search Desktop Thunderbird with multiple accounts for email message that were sent/arrived during a specific date range, a "Global" search which covers multiple accounts. All of the guidance I have found online result with me needing to pick a particular account.

I recently (unwisely) refreshed my Windows 10. I had to relaod Thunderbird, but when I tried to reinstal my previous profile, I couldn't do so. I've tried using profile manager. but it only seems to recognise two of the six or so profiles that exist in my profile folder. This means I can't access several years' worth of emails - I need to access these for invoice and work purposes. What is really frustrating is that I can see the profile I need in the profile folder, and all the emails seem to in the Mail/popmail/Inbox folder (all with a much smaller MSF. file of the same name). I've tried importing the profile into Thunderbird, but that doesn't work, it just imports the mailbox with no subfolders. A responder called David has already kindly provided advice (many thanks, David), but unfortunately the solutions haven't worked. Can anybody help?

What are the memory limits for Thunderbird. Currently, I get this message when I try to save and email "Unable to save your message to local folders. Possibly out of local file storage space." Please see attached screenshot.

I am not out of storage space.

Any suggestions?

Thank you.
