Every start of Thunderbird 128.4.0esr (64bit) on Windows 11 (64bit) I get a dialog with the message: "Zum Ausführen der gewünschten Aktion ist kein E-Mail-Programm zugeordnet. Installieren Sie ein entsprechendes E-Mail-Programm, oder erstellen Sie in der Systemsteuerung unter "Standardprogramme" eine Zuordnung, wenn bereits ein Programm installiert ist."

Thunderbird is the standard E-Mail programm in "Standardprogramme". Reinstallation of Thunderbird did not change the behavior. User account is not administrator. For installing Thunderbird, the administrator password was requested. Windows 11 is freshly installed. Thunderbird has been installed as one of the first programms. Windows is: Windows 11 Pro, Version 24H2, installed 10.10.2024, build 26100.2033. Dialog appeared right from the beginning, even before a profile was imported, and at every program start.

I post-installed two extentions, but the dialog showed up before and after installation and also if I disable them. The dialog appears right after the Thunderbird window has been created (that is after the master password entry of the profile).

Playing around with settings, I experienced, that switching the Thunderbird language from German to English (US), the dialog and message disappear. Could you please fix it with the German language pack?

For the past month or two, at random times when I open Firefox, I see a message stating, "Looks like you reinstalled Firefox." To be clear I have not uninstalled Firefox in any instance where this message has been displayed.

When this happens, I’m unable to browse the web. To resolve the issue, I have to remove the uBlock Origin extension and reinstall it. Once I’ve done that, browsing returns to normal. However, I then need to reconfigure my filters and adjust settings within FireFox

I’ve tried uninstalling and reinstalling Firefox to see if that would prevent this issue, but it hasn’t worked.

This problem is specific to my PC—it has never occurred on my MacBook.

Any assistance in understanding why this happens and how to prevent it would be greatly appreciated.

Thank you.

Hello,

I'm trying to update to firefox version 133.0. My O.S. is Ubuntu 20.04. I've untarred the tarball to ~/firefox/firefox-133.0/.

If I startup the new firefox, I receive the following error message: "libxul.so, undefined symbol: gdk_window_show_menu".

I also tried firefox version 120.0, except the result was the same.

How can I fix this?

thanks.

My Thunderbird had an automatic upgrade this week to 128.5.1esr 32Bit. Since then, I have not been able to pull down email for any of my accounts. When attempting to pull email from remote servers, the Thunderbird status message is "Checking server capabilities ....". This has gone for hours with no change, or the attempt just stops with no status update and no emails. This occurs regardless of VPN usage. What happened and how do I fix this ?!?!?

I have 128.5.0esr (64-bit) running on a Chromebook, about a week ago it started only showing the top of message boxes and no content. So if you say go to delete an Event from the Calendar you can't as a box pops up but only has the banner at the top saying 'Delete Event' with the close option at the end of it, the rest of the box with the 'Yes' option is missing. Any ideas on how to fix this? thanks

How can I roll back or uninstall this latest update? I'm suddenly stuck with this big stupid empty sidebar and it's an eyesore and distracting and I hate it. Almost worth going back to Edge for it. I want it gone. Nobody wants bezels on their phones/devices, who the hell thought it was a good idea to take up more window on their web browser!?

After an update notification, i downloaded and updated my firefox to version 132.0.1. after the update, i continually get the notification to update. when i try to perform the update again,i get a message that reads "failed to check for updates". please help this notification is very annoying...

Having updated to latest browser version I am continually getting this page

https://www.mozilla.org/en-GB/firefox/133.0/whatsnew/?oldversion=132.0

It is not in my startup URL's I use the default.

I have cleared all browser cache and data with no effect.

Hi, using Mac OS. Have tried the about:config set the auto update configs to false, still it keeps prompting every day or a few hours . There is also a timer setting. They dont seem to work, and these update notifications are very irritating, keep popping up every 8 hours or so.

Not sure the necessity for these incessive updates every day or hours, it uses a lot of system resources and hdd space, can Firefox put back the option when we can just tick 'update only when we want them' , in these, no background timer required they use system resources and there are many of us do not want them.

This question has been answered: see below

I've replaced K9 with Thunderbird (version 8.1) on my Ultrahertz Jelly Star running Lineage 20. Everything works as expected, but I can't get the Thunderbird app to appear in the homescreen apps list on my custom launcher, AOI (version 5.2.4).

The homescreen apps list is driven by a Category setting within AOI, and I have a category called Frequent to surface apps I use all the time. Earlier apps added to the Frequent category appear as expected, but nothing I've tried surfaces Thunderbird in the same way.

RESOLUTION

In the course of gathering information for this question I inadvertently deleted the Frequent category within AOI Launcher. After recreating it, and adding my most frequently used apps, Thunderbird is now included in their number.

Every few days I get a Can't load XPcom error when trying to launch Thunderbird. I know how to fix this problem when it occurs (manually delete T'bird from Programs, download and install latest version), but every few days it occurs again, which is getting tiring. How can I fix this so the error won't occur, at least not so often?
