After updating from TB 102.7.0 to TB 102.9.0 on my Mac OS 10.15.7, I cannot send mail on one of my mail accounts and getting the following message: "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtphm.sympatico.ca was lost in the middle of the transaction." With the previous versions of TB, I did not have any issue with this problem. The settings of this SMTP server is: Port 587, Connection Security SSL/TLS, Authentication method = Normal password. These settings worked perfectly in the previous version of TB! Any suggestions? Thanks.

Thunderbird has become unusable for me with the latest update on March 28th. It takes about 10-20 seconds to respond to clicks to delete emails. As you can guess, this makes it impossible to work with and I've had to switch to Outlook.

Whatever the issue is with this change, it needs to be resolved.

I'm unable to find away to revert back to the older version. Is there a link to older versions?

I have a 3:2 laptop whihc means that it has more vertical estate that your regular laptop, but still the message header is way too big for the amount of information it has to deliver.

I have looked at all the options and there are only ways to make it *bigger*...

Since it's all CSS behind, do you how to override the padding/margin of that element ?

I currently have Spectrum internet and now a new fiber optic company is installing their product in my small rural town. I would love to have them and no longer have to deal with Spectrum's outages, etc. However, they do not offer an email service and suggest that I use gmail or yahoo or other web based service. I do not like either of those and have used Thunderbird for many years. Can anyone Than tell me if it is possible to continue using Thunderbird and how will I do it? Thanks for any help. I just want to add that I am 75 years old and really don't do the technical stuff very well. I am willing to try though.Thanks, Jennifer

Previously if we crafted an HTML email we could use the @media print CSS section to force a page break before or after an element. With Thunderbird 102.9.0 the CSS for forcing a page break is being ignored in HTML emails.

If I save the message source as an HTML file and open it in Firefox the print preview shows the correct page breaks, but in Thunderbird the content all runs together.

Any idea how I can fix issues with the subject and other fields displaying an unreadable font? If I highlight the areas, the font is readable and sometimes it is fine. See attached example - subject line should read: "Use Color-Changing Sequins to Tell Time"

Guys I'm looking to install Thunderbird beta on my Mac in parallel with release version. The only instructions I can find on the web seem to relate to the Windows version.

Or is it as simple as running the installer and choosing 'Keep Both'?

Any assistance is appreciated.

Hey. I have countless issues with Thunderbird, but two I need to solve now:

1. TB doesn't respect setting called "Sync last x days of emails" and sync everything. That causes it to consume lot of resources and my PC is very slow and fan has to run full blast. 2. I have changed login info on my CalDAV calendar so I wanted to remove the old ones and add the new one. However the old one wasn't somehow properly removed from my Ubuntu online accounts and TB keeps ghosting me to enter login info of account that doesn't exist anymore.

Version: latest Platform: Ubuntu 22.04

Tbird tries to save a lengthy email as a draft, I assume after a certain about of time passes, but fails to do that and I have to keep acknowledging the failed draft save in order to continue.

I never save drafts and don't want it doing this. It just started doing this after the latest update. I have four accounts and it only does it with one account, although I don't write time-consuming emails with the other accounts, so maybe it would do the same.

This account has another problem, too. It doesn't save a sent email in the sent folder for this account. The other three accounts all do, and all the settings look the same. Again, this happened after the latest update. I'll have to change email clients if this isn't resolved as I need to retain copies of sent email from this account. That would be sad for me, as I've used TBird for probably 15 years or thereabouts.

I have wondered in the past, why the Inbox file (without extension) is so big. Today I moved all subfolders and remaining message from the Inbox. So there is literally NOTHING in the Inbox, but the Inbox file is still nearly 3 GB. How is this possible?!? Are there invisible files, settings, etc. saved in it? Is there a way to reduce the file size?

Also the Drafts folder/file is 1 GB but there is nothing in it. I just emptied the Junk folder and it still shows up with nearly 1 GB. This is very strange.

Please advise! Thanks!

Since one of the last updates the behaviour for the tab re-sizing got messed up.

When there are only a few tabs with full size, those as well as the additional plus icon is shown. But when there are more tabs and they are re-sized, then the right side gets cut off. First the new tab icon dissapears and then also the last tab get's cut off.

I attached a screenshot with three firefox browser windows showing the problem, as well as a forth one with only 3 tabs open, which are shown in full size including the new tab icon.

This is a new problem as the tab resizinng and the new tab icon used to work perfectly fine no matter how many tabs were opened.

Hello. I un-installed Microsoft Edge and Office 365 and now Firefox has stopped working (on another computer not this one).

This is the same problem that someone reported in 2021, but that thread has been archived.

https://support.mozilla.org/bm/questions/1356550

The advice then was to re-install Firefox and to download Visual C++ \ Visual Studio files ( especially VCRuntime1401.dll).

My problem is that I don't have a browser on that computer, I am completely cut off from the internet and can't download anything.

Is it possible to download the necessary files on this computer and transfer them to the one that has the problem? Thanks.
