Thunderbird on the Linux Fedora-40 workstation: unknown version (the workstation has since totally failed), but it was up to date as of the end of March 2025.

Thunderbird on the win-10 box: 137.0.2 (64 bit).

On my Linux Fedora-40 workstation, I backed up ($HOME)/.thunderbird (the whole thing) to a USB stick. Now I need to get all the Lightning calendar data (tasks, holidays, and so on) into Thunderbird on the win-10 box. I want the Calendar data only. 1. What do I need to copy? 2. Where in my win-10 box do I put the files that I should copy? 3. What other steps do I need to do?

Thank-you!

Hello, I can't install - or rather trnsfer - Thunderbird to my new mobile phone despite it works allright on my Laptop. Can you possibly help me? Regards Uffe Nellemose [email protected]

Sometime last week, my snap thunderbird package updated to version 128.9.1esr. After that update, clicking on the Thunderbird icon in the dock starts thunderbird under a generic icon that appears on the right side of the dock (showing the dot indicator under it), rather than showing the thunderbird icon with the running indicator under it.

I am using X11, fully updated Ubuntu 24.04.2, with Thunderbird installed as a snap. Work correctly until last week. If I start the application manually from the command line, same generic icon appears. (If I start firefox snap from the command line, the firefox icon shows the "running" indicator under it as it is supposed to.

Note: Thunderbird IS running and running fine - I have not found any other issues, just this potential regression.

Anyone have any ideas? I thought I would post here before filing a bugzilla bug report. I was not able to find any mention of this (or a similar) problem in the last year.

Thanks.

Hello,

We are trying to automate updating Firefox ESR from 32bit to 64bit. There seems to be an issue with getting user's profiles to properly migrate for ESR. If we do a plain 32bit uninstall and 64bit installation, a new "default-esr-1" profile gets created (which is expected behavior from these Mozilla docs for new installs). But, when we set the MOZ_LEGACY_PROFILES=1 policy, this reverts to using the "default" profile instead of "default-esr" profile that was previously in use.

Are there any known ways around this which does not require user intervention to manually change back to the "default-esr" profile?

Thank you

I just tried to download Thunderbird on my computer today but it did not end up listed as an installed app, nor was I taken through any of the installation steps.

I have been using Firefox for a few years, and have received my primary mail account through Firefox. I noted that a Thunderbird app was already installed on my computer, so I tried to find a way to use it for my email. I was not able to do so, and thought that it would be best to delete it and reinstall it. But I can still not find a way to find its icon much less view my email in it. Please help me understand what I have been doing wrong.

‘I need Firefox Browser on my Huawei Tablet. Mozilla keeps showing me links to Google playstore that is restricted for Huwawei devices. How can I get Firefox onto my tablet?’

I am already a long time user of Firefox on this, my PC

I tried the link to the Firefox in the Huawei App store but it is effectively dead with no options to download the browser

Thank you for any suggestions!
