Recently, I have experienced an erroneous browser launch, simply by clicking on the title of the message in the list pane. This problem seems to occur when clicking on emails from a particular UK supermarket (tesco.com) and the web page opened has a long and complicated URL, but the page contains only a single pixel which shows up as a white dot on a black background.

Obviously, it is likely that there is something strange about that source, but the problem doesn't occur if I click on the same email in a different email client (in this case Evolution).

I have tried various Settings as advised by web searches and also the solutions suggested in Thunderbird Help (Troubleshooting Mode and Troubleshooting Information).

I am running Thunderbird 140.5.0esr (64-bit) on Kubuntu Linux 24.04.

После недавнего обновления браузер перестал открывать сстраницы или открывает их очень медленно. Я очистил кеш, отключил производительность и ничего не помогает. Как решить это проблему? Пс. Хром работает отлично на этом же ПК.

Many of my emails received are auto marked/shown as having been read. This means I never know which of my many emails received are new and which I have already read. Particularly annoying as I have a number of aliases and a number of folders to put them in. I am actively considering going back to MS Outlook, which would be regressive.

I've been running TB for 10-12 years, generally with no problems. When I logged in on 5/13/26, I saw that Windows had run an overnight update:

    2026-05 Security Update (KB5089549) (26200.8457)

Thunderbird (version 147.0.2.0) was not running, although it had been when I slept the PC the previous night.

Now, when I try to start TB it gives me the crash report dialog. Selecting the Restart option just brings me back to the crash report.

In searching for possible causes, I see that this may be caused by a bad profile. So I open the profile folder with (run) %APPDATA%\Thunderbird\Profiles\ which in my case is:

  C:\Users\<user_name>\AppData\Roaming\Thunderbird\Profiles

This is an empty directory. But if I go up one level to \Thunderbird there is a profile.ini file which contains (actual user ID replaced by <user_ID>:

[Install8216C80C92C4E828] Default=E:\Thunderbird\Profiles

[Profile0] Name=<user_ID> IsRelative=0 Path=E:\Thunderbird\Profiles Default=1

[General] StartWithLastProfile=1 Version=2

"E:\Thunderbird\" is the correct location of my TB installation. In that directory is a profile.ini file that contains:

[General] StartWithLastProfile=1

[Profile0] Name=default IsRelative=1 Path=Profiles/<user_ID>.default

Directory "E:\Thunderbird\Profiles\<user_ID>.default" is present. But all of it's files are dated 2010 except Mail, dated 2016.

Directory "E:\Thunderbird\Profiles" contains the ImapMail and Mail sub directories totaling about 25GB data.

I don't know what the Thunderbird startup process is or if this all looks correct. Can someone give me a sanity check? If this looks normal, what else could be corrupted?

Thanks in advance.

Hi,

I searched the web for deleting the item "Weitere Lesezeichen" in the sidebar. I found only solutions for the firefox 85. In Firefox 85 should be a field for hiding this. Although in Firefox 150 it can`t be hided or deleted. I don`t need and I don`t want this "Weitere Lesezeichen". Any solutions?

Hello. When I opened my browser, you forcefully opened a tab about VPN and how to install this. However I cannot find the mentioned "get started" button.

This is the page that automatically opened: https://support.mozilla.org/en-US/kb/built-in-vpn?utm_source=www.firefox.com

Co żeście spieprzyli w tej przeglądarce? Claude AI zawiesza całą przeglądarkę. Od kilku wersji coś jest fundamentalnie zchrzanione bo nawet Pikvm nie serwuje obrazu. Do tego popsuliście coś z profilami, że nie można wrócić do starej wersji przeglądarki. Cała masa błędów. Na siłę próbujecie udaremnić działanie wtyczek blokujących szpiegowanie użytkowników?

I have filled in an un-correct password a number of times due to incorrect language setting of my keyboard. Then the popup window for this disappeared, and I cannot find a place to enter password. What can I do? It is the password for outgoing email.
