Thunderbird Community Forum

I have TB setup to allow customstylesheets with userChrome and userContent.css files generated. I have userChrome setup to my liking. Now I want to modify the userContent.css file so that I can set the background color of almost all elements is #222226 except for email text, hyperlinks, and imbedded images. I have this setup now in userContent.css:

body { background-color: #222226 !important; }

{ color: white !important; /* Changes font color to white for all content */ }

This changes most elements the way I want but it also flips the color of other HTML content, embedded images for signatures and other html content so its inverted to unreadable white content with white text. Is there a way to set it up so that HTML content and images are not inverted?

TB version 140 Debian Edition on Linux Mint Cinnamon 22.3

I haven't updated Thunderbird since version 52.9.1 because of the interfaces which are painful for me and I don't see much. it still works well but does not support encrypted emails. I would like to install a recent version of TB but how can I make it look like the older, much more configurable versions? Please tell me if this is even possible.

On January 1 my desktop version stopped downloading my GMAIL but my other non gmail are still downloading

I use Windows 10 and the version of Thunderbird is 147.0 64 bit

What can I do to fix this?

I quite often get this message, though it tends not to be a problem later "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox"

One of the solutions seems to be Compact a File. How do I do this?

I keep getting a certificate error on my Thunderbird. The certificate refers to an email account i no longer have (Personal domain) and i have removed the account in thunderbird, and also removed previous certificate exceptions.

I have been through all menus and settings, and cannot find anywhere where it refers to that domain (and subdomain) I have also removed one entry with that FQDN in the outgoing server section.

What to do?

Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks

My problem is that JPEG attachments don't open, though PNGs do. I've got Original HTML actioned. Defaults are set to Fastone Image Viewer. Right click shows options but "open" doesn't work. Any ideas?

Good day,

I have installed the latest version for win64. Every time the software is downloading emails (I use POP3 for gmail), if I am concurrently doing something else with it (e.g. selecting an email with the right mouse button to delete it, or creating an event for the calendar, or just selecting something from the menu bar), the software gets stuck. I then have to kill it and restart, sometimes it takes multiple kill and restart sequences.

I am using Thunderbird from the very beginning o fit, but this issue is pretty annoying. Any advise?

Thanks and BR M

Have no idea to whom I was chatting a week or so ago, but outlook.office365.com was recommended to me as the incoming server setting for Outlook.com. Set TB that way and used it for a week or so. TODAY got a "failure to authenticate" error from TB (have had many such errors before). Went directly to Copilot, as I thought it would be the most authoritarian place to clear up Microsoft problems. It provided the informaiton below: Official Outlook.com Thunderbird Incoming Server Settings (2026) IMAP (recommended) Settings Server name: imap-mail.outlook.com Port: 993 Security: SSL/TLS Authentication; OAuth2 Username; Your full Outlook.com email address

Why this is the correct server Outlook.com, Hotmail, Live, and MSN accounts do not use outlook.office365.com .

Set outlook account incoming server to imap-mail.outlook.com and reset TB Immediately got: Mozilla Thunderbird Thunderbird Authentication failure while connecting to server imap-mail.outlook.com.

Can someone please tell what's going on?

I have a Fedora laptop which has run Thunderbird on KDE Plasma for years.

I typically put the Thunderbird window on my big monitor where everything works as expected.

When I move the window to the laptop screen (or unplug the laptop and use it without the big screen), I can navigate the folder list in the left-hand pane, but the list of emails and body panes on the right do not display, only the Welcome screen.

When I put Thunderbird in Help > Troublehoot Mode, all works as expected.

The only special add on I use is the Get All Mail button.

I recently updated the computers at my shop. My shop uses an older program Mitchell 1 to process and organize invoices. I have used Thunderbird to email invoice pdfs for the longest time but now after updating I get “ERROR SENDING EMAIL. MAPI RETURNED -2147467259” it’s my understanding MAPI is outdated but I figured Thunderbird would still support this function.

Hi,

I’m experiencing an issue while trying to print emails to PDF in Thunderbird. Instead of opening the print preview or print dialog, Thunderbird sends the email straight to the default printer. Because of this, I don’t get the option to choose my PDF printer or adjust print settings.

This started after updating to a newer Thunderbird version, and earlier versions did not behave this way. The menu still shows Print…, which normally indicates a preview or settings window, so this feels like unexpected behavior.

Has anyone else faced this issue, or is there a setting or workaround to restore the print preview before printing? Any help would be appreciated.

Thanks!

Filters *unreliably* sort the mail into their target files. I have reconstructed the filters from scratch twice, both times with identical, unpredictable results: each filter works properly on the inbox when tested, but each filter only works *sometimes* in the normal course of getting (IMAP) and sorting mail. When getting a batch of mail, some messages are sorted, while others are not. When testing the same filters on the same (still unsorted but already picked up) messages, those same messages are recognized and sorted correctly. The question is: Why are the filters not working reliably during message pickup?

The mail server is running "Debian stable" Dovecot. It seems to work well; I'm not *missing* any messages, but they're not always getting into the right folders. Instead, some messages, and sometimes quite a few messages, may remain in the inbox. I surmise that the problem is in Thunderbird, where somehow the downloading process somehow undermines the sorting process. A queuing issue? A communications-with-Dovecot issue? (The server is in Paris and I'm in North America, but there doesn't seem to be any undue latency that I can detect. The server is not very busy, that's for sure.)

In case it helps: I filter mostly on `DKIM-Signature`, `Authentication-Results`, and `Received` header entries. In a couple of cases, I use `Body`. I'm almost always using "match any" (as opposed to "match all").

Hello! I want to set up TBird to: 1) Get all my messages and attachments stored locally, and... 2) Remove *most* of the above from gmail's server to avoid the data limit, but... 3) Keep, perhaps some months or a year of activity on gmail's server so I can access recent items from wherever.

Questions: 1) I have 10s of thousands (more?) of msgs, many with attachments. Is it better to just set up TBIrd and let it grab all the messages, or start by using Google TakeOut? 2) I presume I use IMAP vs. POP? 3) To preserve messages on my harddrive, I could archive to a local folder. Then I could safely delete those same messages on the gmail web interface? 4) If this turns into a disaster, can I just remove the entire account from TBird without suffering a loss of my entire email history? 5) Any insurance maneuvers to prevent the disaster of accidentally losing my entire email history while attempting to set this up? (Obviously will need to be religious about backing up my own system, though keeping a year of email on the gmail server offers a bit of insurance once the set up is successful.)

I am really hoping to avoid creating a unholy mess of my email/spending a week trying to fix it. (Indeed, I have avoided this project for years for this reason, but I really, really want to do this.)

Lately, when I try to click on a different mailbox or message , nothing happens. repeating clicks sometimes works, and sometimes i have to first click on what I was previous viewing to get what I want to highlight, or click on different areas of a message or mailbox to get it to work. I am on mac tahoe 26.2. Did not have this problem before. What can I do to fix this problem?

Thanks Dan

My Spectrum-TB connect was functional yesterday but is not working today; NO password or setting changes! Contacted Spectrum and was able to successful send an email from Spectrum's online webmail to a gmail account.

Hello,

since some years I use the facebook calender url in the calender tab.

Since some days the are no entries shown anymore.

The same calender url is correctly used in google calender (web & app)

The facebook url is as followed:

https://www.facebook.com/events/ical/upcoming/?uid=100001094911980&key=XXXVO6gUO0v9U63j

It would be helpful to have a solution or at least an explanation for this problem.

Sorry - I feel as though I'm monopolising this forum at the moment!

In my Menu bar, I have Delete, but, using this, I can only delete emails from the Unified list, not individual accounts. I CAN delete from individual accounts if I select the email, right click and select delete. Seems odd

My Computer in Spain worked perfect wit my Emails until about 5 years ago when you upgraded thunderbird

Since Then it will not recognize my LOG IN passwords for both my Google email and my Plusnet email

I have had to access Gmail via there website but I like your set far better

I have had to access plus net via web mail which is very basic

Both Passwords work perfect in England

I have now set up another Computer and this time Thunderbird does recognize my Gmail password but still tells me my Plus net Password is not correct

I contacted Plus net last December from England and they confirmed that the Password is correct Have you any suggestions as to how I can solve this problem

I use windows 7 ON ALL MY COMPUTERS

Yours sincerely
