Hello,

does anyone observe an issue that Thunderbird [140.4.0esr (aarch64) / macOS 26.0.1 (25A362)] freezes for 5 seconds after sending an e-mail? This is super annoying...

Just installed TB for Android on Samsung S24 Fe. Works fine but am unable to exit the application other than forcing phone back to home screen. Have installed on a Samsung tablet and the back button seems to be working OK. Anyone know of any issues with this phone and TB?

Latest version on W10 desktop machine.

1. Setting to open message in a new window does not work. Insists on making a new tab instead.

2. When Thunderbird window is active, kills attempts to use desktop icons for other programs.

3. Cannot minimize Thunderbird via taskbar. Have to hit minimize(-) from window.

Can any of these be remedied?

I use Thunderbird on Windows and on Mac. I'm wondering why the startup time on Mac is significantly longer on MacOS. I'm currently on Tahoe 26.0.1 but Thunderbird has always been a slow starter. Can I change any setting to remedy this. At the moment I have two mail accounts configured both Gmail.

I have a message that is still listed after being deleted. When I highlight the messages listed above it and below it, I can see their contents with no problem. However, when I click on the "ghost message" listing in between them, I will see the contents of the last message viewed, not the contents of the ghost message that is highlighted.

Also, when I first open Thunderbird and highlight that ghost message first, the review pane is blank, like there is no message there. Then if I click on a different message, that message's contents will show in the preview pane. Then when I go back and click on the the ghost message listing, that pane is still showing the previous message's contents.

When I click on "delete" message, I get the constant blue indicator light in the lower right glowing and nothing happens.

I have nothing but problems with firefox since the last new updates. Sites hang, gmail can't be accessed, it takes 100x longer for sites to load, firefox uses huge amounts of memory and CPU, etc, etc.

I am so fedup spending valued worktime having to solve firefox issues each time they decide to make updates - which seems to be more and more frequent. How can I roll back to a previous version and permanently disable any further updates?

Each time I click on Firefox from the Windows 11 Task Bar, multiple versions of Firefox appear in the task manager (see photo). Some have an icon next to them that says "efficiency mode".

The attached screenshot is what I got from loading Firefox to ask this question. Multiple scans of my computer using Norton 360 -- including the Startup Scan -- have found nothing awry.

The operating system is Windows 11 Pro Edition Version 24H2 (OS Build 26,100.6584.) Firefox says it is fully up to date.

I noticed that I can't see the end of any longer email messages and realized that the Status bar is missing in the email window, too. Changing the relevant setting in the menu didn't do anything. The Status bar is visible in other tabs. When I hid the Today Pane (Events & Tasks), the status bar came back. When I displayed it, Status bar disappeared again. With longer email messages, it is impossible to view the complete message, because the message window seems to extend below the screen bottom. Hiding Windows task bar doesn't help.

Help, how can I have my status bar and read the messages without opening them in a new window, without having to hide the Today pane?

local folders after a certain amount of folders have disappeared. I have made a new folder today, it displayed, closed thunderbird, re-opened thinderbird, and folder disappeared, the .msl file and file are still in the profile/mail/localfolders directory, just not being display under local folders in program, deleted all .msl files, and restarted thunderbird, and it did not recreate the .msl file(s) as well

When Firefox ver. 143.0.4 (64bit) is opened, I see many tiny groups of black dots withing the whole of the desktop display of this Firefox. From these black dots I see coloured lines traveling across the desktop within the Firefox desktop display. As I move the mouse these coloured lined move, disappear, and move around. Can you offer any suggestions. I am using Ubuntu UALinux Gamepack 22.04, The version of Firefox is an upgrade provided by Firefox updates. I have tried to uninstall this version of Firefox, same effect occuring. I have manually deleted every referance to Firefox, as this worked in UALinux Gamepack 20.04. I have used sudo apt update, sudo apt upgrade, sudo apt --fix-broken install, and sudo dpkg --configure -a. None of these can fix this problem. I restarted my Firefox today with the same problem, and found in the Help dropdown menu, and found troubleshoot mode. When I opened in troubleshoot mode, all these problems are not there any more.

Can you offer any help ??????

P.S. I tryed to take a screenshot of this problem, but the screenshot doesn't show this problem ?

I have only 4GB RAM and that can be an additional factor that causes this issue. When I listen to Youtube Premium in the background (with video window hidden) and switch to Firefox, Youtube Android App is killed. Same thing happen with Youtube Music from time to time. For Youtube, I can workarund this issue by keeping video in Picture-in-Picture (PIP) mode.

Hi,

I am having the issues on more than 1 pc that after updating the firefox esr 128 version to 140 esr version, the firefox does not work properly, specially with xWiki. when i click on xwiki (on-premis server), i can read the contents and all. but when i click edit then it shows the blank page. this is very odd as it happens after updating to 140 version. picture is attached.

Thanks Sheras

On a new tab in Firefox Focus for iOS 26, the floating keypad first appears, and once Dragged to bottom to make the full keypad, it glitches, erases what I wrote, and brings up floating keypad again. I know this is a beta and has bugs, this is just FYSA for iOS 26

Thunderbird very slow to respond when opening the program. On opening any email it freezes for a couple of seconds resulting in a "Wait for the program to respond" or "close program message" . This also happens when performing any action in Thunderbird. This has been happening for the past two or three weeks. Can you tell me how to fix this or is it something you need to do to fix.

Hello. The Thunderbird on my MacBook Air is extremely slow and slowing down the other applications. On the other hand, Thunderbird works perfectly on my iPhone. What can I do?’

On macOS Tahoe 26.0, Thunderbird 143.0.1 does not give control to Finder, when I quit the application. To gain control, I have to click the Finder icon on the Dock, for example. Could someone identify the problem and solve it?

I run Thunderbird 128.12.0esr 64bit on Linux Mint 21.3 Cinnamon.

Ever since I updated to this version 128.12.0esr, T-bird email manager has become almost useless. Constant freezing, constant repopulating at times and of course freezing. Including changing my folder configurations.

Every time I access the calendar it locks up my system. uses 5gb memory and 5% of CPU Freezing & Slowing the system. Often I have to close it to regain control over the rest of my programs.

I have a 32gb RAM, 12th Gen Intel© Core™ i9-12900HK × 14,

Each time open T-bird i am not always able to access one of my 5 email accounts. I have been using T-bird for over 10yrs so I have gone through some up/downs, but nothing like this before.

"It's so bad that I am trying out Evolution to see if I can switch."

I shouldn't ever have any issues with any programs, especially on Linux based on my systems capabilities.

I see a lot of people are having issues with this version and nobody seems to be fixing the problems.

I need some actionable FIXES or to know this issue is being taken seriously before I abandon T-bird and try out something else. I'd like to have a functional T-bird.

Thank you
