突然、どこにもメールの送信ができなくなってしまいました。 受信はできます。 KDDIを使っていますが、問い合わせしましたが、サーバーに問題ありません。 Webメールでは送信できます。 Thunderbird側の問題のようです。 添付のようなメッセージが表示されエラーになってしまいます。 解決策を教えてください。

Suddenly, I can no longer send emails anywhere. I can still receive emails. I use KDDI, and I contacted them, but they said there are no issues with their servers. I can send emails using webmail. It seems to be an issue with Thunderbird. The message shown in the attachment appears, and I get an error. Please let me know how to fix this.

Firefox just updated a few days ago to version 149.0. Prior to, no issues. Now every time I enter a search term and hit enter. A new tab opens and the page is blank. It only happened after the update. Closing the tab and doing the same thing again opens a new page correctly.

I followed the recommended procedure to transfer the TB profile from an older W10 computer to a new W11 computer (both using POP accounts ), via a USB Flash Drive. The folders are all listed on the USB profile copy and observed during the scrolling detailed view while being copied to the new computer. Nevertheless, they are NOT listed in Local Folders on the new profile. Instead, ALL the messages (approx 700 of them!) are presented as UNREAD in the inbox folder. How can I restore the original folder sorting?

As long as I've used TB, which is many years now, I've had no complaints. I have absolutely no desire to change to a different program.

That being said, I'm at wits' end with the recent issue of Notification Sound Alerts (NSA) upon delivery of a new message. Simply stated, beginning about 6 or 8 months ago, the NSA seem to simply work whenever they want to. I can go a month or two at a time and receive the NSA, and then suddenly one day, NSA will stop functioning on its own. This "pause," we'll call it, will last 4 or 5 months, then then suddenly begin to work again.

I have attempted every imaginable fix as recommended in this forum. There's no need to list them all, because I've made every suggested adjustment that's been recommended. But there's no rhyme or reason to why the NSA will work as programed for a period, and then decide on its own to stop working.

I don't know if this is a glitch in TB that is simply beyond my feeble attempts to rectify, or if any other TB users are experiencing the same issue. I have even gone so far as to attempt to find an Add-On that will supplement the NSA. However, none that I have uncovered, particularly those suggested in this Forum, seem to be compatible with either the version of TB or Windows 10. I understand that Win 10 is not longer supported in the forum, but please! I do not want to migrate years of email files to another program. I want to use TB but simply need to be "Alerted" when new messages hit the Inbox.

Any assistance or suggestions (except those basic adjustments that proliferate the forum, i.e insure the sound mixer is not muted, etc, etc) would be greatly appreciated and thanks for listening.

I run TBD 140.8.0 esr (64 bit) under Debian 12 Linux. Until recently I could automatically enter a special address from the pertaining addressbook, this does not work anymore. helpfiles do not show a solution thus I am here.

The addressbook is full of addresses however I have to transfer a special address via past and copy into the addressfield of the mail I want to send.

Thanks for a quick answer Jörg Kampmann

In Firefox version 149, there is an issue with print preview behavior for HTML <select> elements. When opening print preview, all <option> items inside a dropdown are displayed and included in the print output.

This behavior differs from Firefox 148, where only the selected option is rendered correctly during print preview.

Steps to reproduce:

- Create an HTML page with a <select> dropdown containing multiple <option> elements. - Select one of the options. - Open print preview (Ctrl + P).

Expected result: Only the selected option should be visible and printed.

Actual result: All options inside the <select> element are displayed and printed.

Impact: This issue breaks the layout of printed documents and makes forms difficult to read, especially when dropdowns contain many options.

I installed Mozilla Firefox on my phone, but I cannot log in or create a new account. When I try to sign up or log in, it does not work properly. Please help me fix this issue.
