Every time I try to open Thunderbird mail, I get a screen to install it again!!. Why is this.?? Is there a way to keep it installed.? Or must I jump through hoops each time I need to use email.?

Ever since last maj, windows are no longer resizable. Same Thunderbird version works OK on my laptop running Debian 12, but I cant easily upgrade version Debian 11 to debian 12 on this older desktop, so I wonder whether I could possibly de-install v140.13.0esr and re-install an older version, if then, which one would be suitable and available. If not, is there another trick to resize windows on v140.13.0esr ? Thanks in advance for your help.

I bought a new pc with windows 11 and everything is fine except that I installed thunderbird via microsoft store and when I gave it my email address, I could see my emails but it hasn't created a profile. Therefore when a try to view the profile it says user.../appdata/roaming/thunderbird/profiles... doesn't exist. I am logged on as an administrator. Should I uninstall then install from the mozilla website directly?

Recently I moved from a Thinkpad X1Yoga running Mint and Windows 10 to a Thinkpad P14s running Kubuntu and Windows 11 Pro 25H2. On the Win11 side (which behaves differently from Win10), there are installation issues affecting both Firefox and Thunderbird.

Win 11 Settings lists: under Apps > Installed apps

• . . . (other apps)
• Mozilla Firefox (x64 en-US) 154.0
• Mozilla Maintenance Service 153.0
• Mozilla Thunderbird (x64 en-US) 153.0.2
• . . . (other apps)

under Apps > Default apps

• . . . (other apps)
• Firefox
• Firefox
• . . . (other apps)

That is, Default apps lists Firefox twice (though not as "Mozilla Firefox"), but Thunderbird not at all. This causes two problems:

1. It's not clear which Firefox to choose for browser protocols.
2. There is no Thunderbird to choose for mail-related protocols,

Can someone tell me why the Installed apps and Default apps list differ, and how to set the appropriate defaults for Firefox and Thunderbird?

Thanks, John

Dell Desktop - Windows 10 to Lenovo Laptop Windows 11 I followed the Alternative Manual Transfer between Windows 10/11 Roaming Profile and Local Profile Now on Lenova - Mozilla will not open - Profile Missing - Your Thunderbird profile cannot be loaded. It may be missing or inaccessible. I do not know how to uninstall it or how to start over.

I am encountering a message of "The installation seems to be incomplete. Please check your hardware and disk setup and/or re-install." when trying to run Thunderbird.

This first occurred on a system that had been working for a while. An update may have been installed.

Here's what I've tried. -

Uninstall Thunderbird (along with Firefox and Mozilla Maintenance.) Checked for Program Files/Mozilla folder (all were removed). Run SFC / Scannow Run CHKDSK Installed pending Windows update. Restarted the System Renamed (essentially removed) Profiles folder Turned antivirus software off Downloaded and installed the latest version of Firefox, then Thunderbird. Launched Thunderbird. Still received the same error..

Any ideas on how to resolve the issue?

Version 154 (64 bit) creates a start menu shortcut in %appdata%/Microsoft/Windows/StartMenu/Programs/ with each and every launch. I have Firefox installed to "C:\Program Files\Mozilla Firefox\

Installing a shortcut at launch is undesirable to say the least.

Is there a way I can disable this behavior?

I can't find latest Firefox apk for my android. It only shows play store link. I tried signing up for Gmail account but that requires phone number verification these days. Never in my life was creating a Gmail account so much hard. It doesn't even give option to get code on some other number. The only option it shows is to insert a sim and google will verify itself which is kinda annoying. Please share the latest official Firefox apk link. It's impossible for me to create Gmail account as there is no Sim in my phone.

My Mac last night lost thunderbird (and numerous others things) and it's setting itself up again. I get an error that smpt already exists and I can't go any further! What's going on? Using Comcast Mail.

I am trying to evaluate your product, but i cannot load the program. it appears that this product does not have technical support. If the only technical support is from a forum or community, i will look at other products. i do not know the version since i cannot load it

I installed thunderbird for Windows on PC all was good till it went looking for a outgoing server a red box popped up and said outgoing server is already installed . That ended the install.
