I went into the Settings, under Calendar, and unchecked "Show week number in views and minimonth"

On the main page, my view is the Accounts on the left, the reading and message pane in the middle, and Events pane on the right.

In the Events pane on the right, it displays the date at the top and CW ##.

I would like to remove that CW ##. If the option I unchecked does not apply to the events pane, can you make another option to does remove CW or make it the option I unchecked work for that also?

See screenshots.

I've inadvertently made some change to 'Open with' so that when I add an attachment I can not open it within the email I'm sending. It opens for the recipient but not for me. When I click on the attachment nothing happens. It doesn't occur for all attachments but it seems to be for any attachment requiring 'Photos' as the option to open. Can you help please?

I have 2 computers, both with Linux Ubuntu. All of a sudden one of them is missing the File toolbar. It was there this AM but gone now. I looked through the menu and couldn't find where it is that you add the toolbar. On this computer, which has that toolbar, you go to 'view" and there is an item for toolbar. But on the other there are none of those menus and I can't find where to add that toolbar.

Hello,

I am a super happy user of Thunderbird calendar since many years.

Now that my kids have a lot of activities I am facing an annoying display issue with the upper part of the calendar in the Week view showing all days event : it is too small to show all events at once and hence proposes a scrollbar to navigate inside it (the attached image shows it for Tuesday May 13)

To solve that, I would be super happy just to select the "horizontal line" separating the all day events pane from the one below and then drag it to increase the height of the all day events pane. Unfortunately this is not possible.

So my question is : how can I increase the height of all day events pane so that I can see all my all days events at once ?

Thank you very much for your help,

In the article https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-firefox-deb-package-for-debian-based-distributions-recommended

https://packages.mozilla.org/apt leads to 404, not a Debian software repository / archive.

Step 4 (is broken)

Next, add the Mozilla APT repository to your sources list:

echo "deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt mozilla main" | sudo tee -a /etc/apt/sources.list.d/mozilla.list > /dev/null

I see it as Thunderbird hijacking the resources of my computer to run Firefox and take me to the donation website. I'm fine with the request for money in the Thunderbird screen, I can navigate away from that. Don't open programs other than Thunderbird before I require them.

I use Thunderbird for email and Edge for my browser. Unfortunately the icons for the two are so similar it's difficult to tell them apart. I'd like to suggest that Thunderbird/Mozilla allow users to substitute their own icons for the running programs if they don't want to use the default one.

currently using FF; I do NOT have any ad blocking software installed ( that I know of) I searched my computer for the word block, and it did not show it anywhere. I also have Mozilla Seamonkey installed, but not using it. Each time I visit a news website I get a popup that claims Im using an ad blocker. I have searched all those adbocker pgms on my computer and none exist. Why am I getting these pop ups. I think I also checked the AVG pgm, but didnt see an adblocker there. How do I fix this situation from continuing

Hello,

The latest version, 128.10.0esr, was recently released, and one of the changes is:

Changed color override defaults with high contrast mode on macOS and Linux

https://www.thunderbird.net/en-US/thunderbird/128.10.0esr/releasenotes/?uri=/thunderbird/releasenotes/&locale=en-US&version=128.10.0&channel=esr&os=Darwin&buildid=20250425031534

I use dark mode, but I prefer to view the email body in light mode, as this is typically the sender’s default formatting. To achieve this, I previously configured: • Settings → General → Fonts & Colors → Colors • Set Text to black and Background to white • Enabled “Override the colors specified by the content with my selections above:” and set it to “Only with High Contrast themes”

However, since this update, this setting no longer works. Now, the only workaround is to manually click the “Turn dark mode off” button for each email, which does work. But it’s inconvenient to do this every time.

Is there a way to disable dark mode for all email bodies by default, so I don’t need to click the button each time?

Thank you!

Yours,

I have 2 instances of Firefox: I use stable for all my professional work, and I use Developer Edition (Aurora Channel) for personal things. The stable branch works fine. In Aurora though, certain key combos will not work. This even persists in troubleshooting (safe) mode.

Specifically, it seems anything using both ctrl+alt will not register alt, only ctrl. alt, alt+shift, and ctrl+shift all seem to work fine, but ctrl+alt and ctrl+alt+shift do not. Again, this works fine in stable, so I am clueless as to why it doesn't work in my other instance.

Another detail is that this happens on multiple websites, not just one. The post prominent one is Google Sheets. In sheets, you can insert the date using `ctrl+;`, the time using `ctrl+shift+;`, and both using `ctrl+alt+shift+;`. Inserting them separately works fine, but both causes only one to insert.

I had set my Ubuntu 22.04 browser to Chromium for a while, but decided that all my cookies are in Firefox so I chose to switch back. Full reset after power-off, of course.

My Environment Variable $BROWSER is now set to Firefox, but Thunderbird apparently has a mind of its own. ;-) It still opens or switches to Chromium with every web link executed.

I've explored the ~/.thunderbird/ directory but see nothing there.

What am I missing that I need to be educated about?

Thanks in advance!

There are 2 questions in the Q&A section without any reply. I have no idea what has transpired since this morning when the dates were perfect. I went out for about 3 hours and on return the clock is showing a 12-hour clock without am or pm. So searching by date and time is a laborious process. I cannot find anything in settings relating to 12 or 24. What am i missing? Thanks

When I click on the minimize "-" in top right corner of Thunderbird it does not minimize to the bottom left task bar as other programs do, but instead goes to the system tray (bottom right). Online help suggested I go to "Settings-General-Language and Appearance" and un-check "Hide system window titlebar". This appears to make no difference. How do I get this back to what it used to be?

For some time now I have had 2 folders for my sent mail. One is called "Sent" and the other one is called "Sent Mail". I have tried to delete one but to no avail. They both have the same files in them.

I also have 2 folders for "Drafts". Same name on both. How can I get rid of these extra files. I've attached a screenshot. I am running Win 11 Pro.

Thanks in advance.
