I have seen a custom css workaround solution to add category colors into calendar events. That solution still relies on calendar events having to be categorized in order to support color functionality.

How is it the year 2024 and Mozilla Thunderbird Calendar doesn't support event colors, independent of categories? This feature has been standard in most major calendar apps for literally decades now. All my Nextcloud calendar events are color coded (without categories), and won't sync to the Thunderbird app.

Can Thunderbird please add this functionality?

I FOUND no close TOPIC.

Google calendar allows color-coding of events - but the display is highly inadequate. T-bird 128 calendar apparently HAS no option to color events. But events are FAR easier to see WHEN color-highlighted. Would this be a difficult option??

Hello,

I am in the process of linking my mail account via Thunderbird on my computer. However, I can no longer see my normal folder structure. However, if I link my account via my Android phone using the Thunderbird app, I have the option of selecting so-called special folders (see attachment screenshot 1). If I then select INBOX, my usual folder structure can be accessed again in the linked mail account on my phone (screenshot 2). Why don't I have this option in Thunderbird on my computer? Perhaps I thought I was using an outdated version of Thunderbird on my computer, but I cannot see the version number and cannot check whether I can update Thunderbird or not.

Hi everyone,

I’m having some trouble with Thunderbird and could use some guidance. I’ve been trying to install the latest version, but I keep running into issues. The installation either fails midway or gives an error message I can’t figure out.

Also, for the times when I’ve managed to install Thunderbird, I’ve noticed that updates don’t seem to apply properly. The program either doesn’t update automatically or prompts me to download the full installer again.

Could someone explain the proper steps for installing Thunderbird and ensuring updates are applied correctly? Are there any common pitfalls or settings I should check to avoid these issues?

Any help would be greatly appreciated!

Thanks!

Up to a few days ago, when someone sent me a meeting invitation by email, I could accept it on my Thunderbird email app (on my windows 11 laptop) and it would be added to my Thunderbird calendar. When I would open an email invitation, there was always a line/bar that would appear below the subject line that would say "this message contains an invitation to an event" on the left side and then buttons with "accept" "tentative" "decline" on the right side of that line. This line/bar no long appears in email event/meeting invitations. On my windows 11 Laptop with Thunderbird version 128.2.1esr (64) bit, that line/bar no longer appears and I can no longer accept event/meeting requests sent to me by email. I could do this before, and I have an example from my old windows 10 laptop using Thunderbird version 115.15.0 (32 bit). Did something change with a new Thunderbird update? Or do I need to change some setting in my Thunderbird version 128.2.1esr (64 bit) app? See attached example of meeting requests received by email on both versions of Thunderbird. The email from the 115 version shows that event line/bar the email from the 128 version doesn't. Any advice? Thanks in advance.

Well. Had my own mail server for going on 25 years. But i decided to switch my mail over to proton mail using my domain. I just cannot justify the server cost for only email. So anyway in Thunderbird i had google smtp and my servers smtp so i could send mail from different accounts. when switching over to proton i went to delete my old server smtp server info leaving only the google smtp server. Then i tried to add a new smtp server with the data protonmail provided and clicked save and it refuses to add a second smtp server. I am stumped as i tried to readd my old smtp server and it will not allow me to add that either. any ideas ?

Hi I have problems after my Thunderbird latest update to 128.5 esr(64bitd). The picture file of my signatures has changed to a larger size, and none of the instructions issued to change this are working or are not there.

Hello I have an application that shows forms where the input fields are inserted on table columns. When the column contains two fields sometimes the second field is showed not in the same line.

It must be said that the second field is added after the creation of the form.

Whit Chrome and Edge the form is showed correctly. At this Link the behavior can be seen. Thanks

Dear Support Team,

I am experiencing an issue where the "Send to -> Mail recipient" option is missing from the context menu in Windows, despite having Mozilla Thunderbird set as my default email client. Steps to reproduce the issue:

   I have set Thunderbird as my default email client in Windows 11.
   MAILTO links work correctly when triggered from a browser or PowerShell (e.g., start-process "mailto:test@example.com" opens Thunderbird as expected).
   However, the "Mail recipient" option is completely missing from the "Send to" context menu.

Additional troubleshooting:

   I have verified that MAILTO is associated with Thunderbird in the Windows default apps settings.
   The registry keys under HKEY_CLASSES_ROOT\mailto\shell\open\command are set to:
   "C:\Path\To\Thunderbird\thunderbird.exe" -osint -compose "%1"
   I have recreated the Mail recipient.MAPIMail shortcut in %APPDATA%\Microsoft\Windows\SendTo pointing to Thunderbird.
   I have reinstalled Thunderbird and checked MAPI compatibility, but the issue persists.
   Running rundll32.exe url.dll,MailToProtocolHandler test@example.com successfully opens Thunderbird.

Observations:

   The issue seems isolated to the context menu functionality.
   The "Mail recipient" shortcut does not appear in the context menu at all, even after manually creating the Mail recipient.MAPIMail file in the SendTo folder.

Could you please help me resolve this issue? Are there any additional settings or configurations I need to adjust to restore the "Send to -> Mail recipient" option for Thunderbird?

Thank you for your assistance.

Best regards, Ondrej

How do I mark something as NOT spam . It seems over zealous now

I keep having to remove things back to inbox but I used to be able to say NOT SPAM on the previous site

samovar@igelbau.com

In the last few weeks when i look at the Washington Post "The Seven" newsletter e-mail there are words missing from the description of each item. Only the words that are underlined are shown. I have found that if I mouse select the text the missing words show up as white text on a blue background. But if I look at the same e-mail directly on AOL (my mail server) there is no problem. The picture shows what it looks like after I do the mouse select. I don't know how to fix this. Please help. George Mells

Back to the topic.

MT new installation - does not remember passwords despite checking the "checkbox" in the IMAP account. This also applies to Google accounts for calendar (non-IMAP account). The password manager is empty. After restarting MT, the same.

I have the same problem as asked in: https://support.mozilla.org/en-US/questions/1440873#question-reply (I can no longer reply to that thread as it has been archived, so I am asking again now in search of an answer).

To reiterate the problem, draft emails are save correctly into the 'Drafts' folder in both Thunderbird and the Gmail web app, but only Thunderbird will correctly delete the draft once the email has been sent. In the Gmail web app, the draft email remains in the 'Drafts' folder.

Why can't Gmail automatically delete draft emails that have been sent? Is there a solution?

I am using Thunderbird 128.5.1esr (64-bit) on Windows 11.

Przenosząc maile do pod folderów (robię to, by mieć porządek na poczcie), giną te maile w powietrzu. Przez długi czas ich nie ma, nie widać. Jeśli potrzebuję się odnieść do przeniesionego maila, to nie mogę, bo go nie ma. Proszę o pomoc, bo to trwa zbyt długo i bardzo utrudnia pracę. Również maile, które się wysyłają, nie zapisują się automatycznie w "wysłanych". Muszę zaznaczyć zapisz w lokalne foldery wysłane. Ta poczta to jakiś dramat, same problemy od samego początku!

I moving from classic outlook to Thunderbird and I am having trouble finding how to change fonts and color in signatures for my emails. I do not do html it is a simple signature; name company name and phone numbers. I search and found no help. Is there a way to change color and font in the reply to an email? Sorry I know this sounds simple but I have been using outlook since it came out so this is similar but just enough to give me trouble. Thank you for any help, rick

I'm unable to send any email with Thunderbird on my new Windows11 laptop. I've used Thunderbird for years and years on the old Windows10 one, but it won't send anything with the new one. The version info it gives is "128.5.1esr (64-bit)" Whenever I try to send an email message, it waits a long long time and then gives a popup saying "Login to server smtp.mail.yahoo.com with username bill.marshall@verizon.net failed." It gives me an option to enter a new password, and if I click there it doesn't let me enter the password again, just re-tries, again waits a long long time, then gives the same error popup. When I cancel, it gives a new popup saying to check the password and verify the 'Authentication method' in Account Settings. Authentication method looks fine, but the password (Settings->SavedPasswords) is empty (?? But I entered the password when I started Thunderbird and asked it to save it).

I have a large amount of emails stored in a mail server (almost 22G), and the service will expire next month. So I want to use Thunder Bird to keep these emails in my local drive for later access. I am new to this software, and have a few questions. 1. Should I use IMAP or POP3 for my purpose? 2. Because it is a huge volume, I guess it may take several days to download all emails. Then, can I turn off Thunder Bird while it is downloading or pause the download process and resume later? What if the downloading process be interrupted due to internet disconnection, power failure or other reasons? Can the software resume where it leaves and ensure the integrity of all emails? Thank you for any help!
