Thunderbird Support Forum

I have a userChrome.css to change the color of unread messages in the "list of messages" pane to orange:

/* Messagepane text */ treechildren::-moz-tree-cell-text(new) {

       color: #34ebdc !important;
       font-weight: normal;

} treechildren::-moz-tree-cell-text(unread) {

       color: #34c6eb !important;
       font-weight: normal !important;

}

This worked fine in TB 102 and prior. When I upgraded to TB 115 this no longer has any effect. I'm not sure if the userChrome.css is being ignored or if the styling elements in userChrome.css have changed.

I'm on Windows 11 and userChrome.css is located in 2 places: C:\Users\$username\AppData\Roaming\Thunderbird\Profiles\$profile.default\chrome\userChrome.css C:\Users\$username\Application Data\Thunderbird\Profiles\$profile.default\chrome\userChrome.css

I was able to send emails till July 14. After that day it's been impossible to send or reply to messages from my Outlook account (I receive emails though). I have made no changes to Thunderbird's configuration since then. Basically it's the Oauth2 authentication that fails. I briefly see a browser page for authentication, wait, wait, wait and then the mail is not sent and I get an error message related to servers timeout (attached). Sorry, my interface is in Italian, but anyway the message is something like: "Unable to send email because of a timeout on the connection to the out server (SMTP) smtp.office365.com. Try again." Is this a known bug? Any ideas? It's quite annoying to use the browser interface to send messages while I am able to receive them in Thunderbird :) Thank you in advance, guys!

Following an automatic update the other day, everything in Thunderbird is oversized. There are in fact some things I can no longer see at all! The program has become very difficult to us to read/write emails. See the image below, a full-screen capture showing the problem . There must be a line to edit in the fonfig file to make the display look normal again. Please help me find that line!! I am visually impaired, and life is difficult enough already! tnx, Paul pgschreier@swissonline.ch

Yesterday I tried the 115 (Supernova) and I was disappointed because of the toolbar on top of the TB window: I think that you should let the user choose where put any toolbar, and I didn't find the way to move in its "classical" place (not at top but below the menu). There is a way to do it? And if not, please consider to give it as soon as possible.

Like many others, I'm seriously considering going back to v112 because I find SO many of the changes in 115 "change for the sake of change," "fixing" things that weren't broken, and breaking functionality that we thought was stable. Not keeping thins like the default font that was selected in the previous version before the upgrade is just plain annoying.

I use Thunderbird to manage many email accounts across different profiles. Not all accounts show up in unified folders, although all accounts are visible in the "All folders" view. Is there any way to "reset" anything to fix this? The Unified folders "Inbox" view in 112 was the best way to see all accounts that had new messages.

Server: smtp.office365.com Port: 587 Connection: STARTTLS Authentication: OAuth2

A browser looking window opens up with a long URL in it (https://login.microsoftonline.com/common/oauth2/v2.0/authorize?response_type=code&client_id=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx&redirect_uri=https%3A%2F%2Flocalhost&scope=https%3A%2F%2Foutlook.office365.com%2FIMAP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FPOP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FSMTP.Send+offline_access&login_hint=xxxxxxxx%40hotmail.com) the windows is just blank and the dialog box for sending opens. The browser window shuts and the sending dialog box just sits there.

It ends up timing out saying it can't connect to the smtp server. I cannot send any e-mails at all. Please help or advise. Thank you!

Hi,

I'm trying to diagnose a random problem I'm having (SOME emails I delete disappear from the inbox and 5 seconds later they reappear).

I can't predict when this will happen, so I'd like to just send logging data to a file. I followed the instructions at https://wiki.mozilla.org/MailNews:Logging and no log file is created.

I set mailnews.imap.loglevel to "All" (without quote marks).

Still no log file and looking at the Error Console, as I gleaned from another reply on this forum, yields nothing whenever I delete an email (whether successfully or not).

Thanks!

Hi, I'm using the latest Thunderbird 115.0 on Windows 11 and use the program with the Preview Pane turned off all the time.

Since I installed 115, when new mail comes in and I click on the notification banner, it brings me into Thunderbird and turns the preview pane back on.

Thanks

After upgade Thunderbird to 115.0.1 version, all my outlook.com email accounts encounter an error:

Warning: Potential Security Risk Ahead Thunderbird detected a potential security threat and did not continue to account.live.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What is the problem? Doesn't TB support outlook.com accounts anymore?

thanks.

Hi,

after updating to new Thunderbird 115.0 menu bar appeared below tool bar and I couldn't find a way how to put it above as in previous versions. Please see attached image. Any idea?

Thank you.

can i go back to ver 102?? can't seem to find how to do this online importexporttool ng is grey out not avail. on new version i save dozens of emails from thunderbird to my computer for 'eternal' storage in pdf format & remove them from thunderbird but can't find an easy way to do this now if i try to save as they all go to a folder with .eml suffix which i don't want, if i try to print to pdf i have to name ea. file & if i try to save them to jpg i have to say 'ok' to ea. file i tried to do 119 files this morning & gave up, hate upgrades that change such important things

The problem affects Mozilla Thunderbird v.115.3.1. I have local folders with subfolders and subfolders within them. Until now, subfolders expanded only after clicking on the folder. And it was very convenient. Now subfolders expand as soon as the mouse hovers over the folder name. This is very uncomfortable. Is it possible to return to the previous solution in the settings?

the hourglass icon comes on whenever I click anywhere in the inbox, and the program makes me wait too long. This is a new problem with the so-called new thunderbird. It is not an improvement; it was made worse. Please fix this bug. And where it says report a bug, I can't report one.

My mother would like to export her very extensive address book in CSV format for safekeeping and eventually for porting it to a new email address. She recently updated to Thunderbird v. 115. I can find help for exporting address books in previous versions. In v115, under Tools, I can only find that a zip file of everything in the profiles directory can be made. Am I looking in the wrong place? Any suggestions besides downgrading to v. 102?

Thunderbird is completely unusable in the latest release. Attempting to set up a gmail based account results in

"Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to 192.168.1.250. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details."

That's it. No options, no explanation, no KB articles, nothing. It just doesn't work. But why is Thunderbird trying to open a web connection to my local machine? If it's trying to talk to itself, why can't it? This is clearly an issue with trying to authenticate to Google as it happens after auth, but come on, this is a given requirement these days. If your app doesn't work out of the box (MacOS 13 btw), it may as well not exist for the OS, so this is very confusing.

Trying out older versions was a real comedy of failures as well. Too old and it's just a disaster. Too new and it just self updated to 115 again which doesn't work. So kinda seems like this is not a functional app anymore, at least not on Mac. Baffling. I guess it can only be used with legacy style email systems.

Hello, I`ve installed TB 115, unfortunately my favourite addon - Display User Agent - doesn`t work. So I`ve downgraded to 102. How long this version will be supported? I`ve searched at google for lifetime of this version, but cannot find this information.

115.2.0 and I am no longer able to receive emails from my outlook.office365.com account. I can send out to other address but can not receive emails from the outlook 365 account. This was working before the version update. Suggestions please.

Just was updated to Thunderbird Supernova. Now when I perform a search with the unified toolbar I get a list of results, but anytime I select one of the results a new tab is open with a Blank message.

I've re-indexed my emails as per : https://support.mozilla.org/en-US/kb/rebuilding-global-database but that hasn't helped.

Anyone else having this problem and found a solution? The only work around I have so far is to use the Ctrl-Shift-F which works, but is a little slower.

Thanks, Robert

After the automatic upgrade to 115.2.2, I have lost access to all my folders, emails and calendar entries. But I can still see my addresses by using Tools/Address Book, and my filters by using Tools/Message Filters.

When I started Thunderbird for the first time on 115.2.2 I got to the usual message page which had all the tabs of the "open" emails I had when I last closed Thunderbird. But there was no sign of my folders and I couldn't get to any other messages (See first screenshot). I also had a second occurrence of Thunderbird running (I could have hit the icon a second time) that didn't show the tabs I had on the first screen. (No screen shot)

On a previous post here https://support.mozilla.org/en-US/questions/1424153 it was suggested that I try Troubleshoot mode. That made no difference and at that time I had no folders showing, and just two tabs. I suspect after that I deleted the tabs.

Now I get a completely blank page in what is usually the message/folder area. Also the button for the address book above the message pane has now gone disappeared (Second screen shot), and I can find no way of accessing my previous (10years+ of messages).

It looks to me as if something is wrong in the profile.

Where do I go from here?
