I just updated to K-9 mail 12.0 on CalyxOS 6.10.20 Which is an Android version 15 K-9 mail crashes on startup. Clearing cache does not work. I'm asking here before i clear all data and try again

I have Thunderbird 146.0.1 on a Win11 system, using POP. This setup has been in place from Windows 7, apart from the Thunderbird client version, and has worked up till the end of 2025. About October last year, I opened Thunderbird, and whenever I selected an email, or a number of emails, Thunderbird seems to get stuck trying to process something. The moving blue bar on the bottom right hand side of Thunderbird shows activity, but never stops. Taskmanager shows that Thunderbird is running, and that something is happening, but I cannot do anything with Thunderbird. I can only shutdown Thunderbird using Taskmanager. I have Norton AV installed, but I have turned it off, and the problem persists. I have removed all the emails from my inbox, and moved them to local files, and the problem persists. I have deleted and recreated my profile, and the problem persists. I have deleted the Thunderbird client and reinstalled it, and the problem persists. It doesn't matter if I select one, or twenty, emails, Thunderbird gets locked whilst processing something, and the problem persists. There is no issue with my Email provider, as I have checked using a webmail client. Emails are being processed and delivered from my email provider, and are received by Thunderbird. I would appreciate any suggestions as to the cause, or more importantly, a possible remedy. I have successfully used Thunderbird for many years, and I actively support them, so I am very keen to resolve this problem. Thank you in anticipation.

Ich habe Thunderbird auf meinem MacBook Air von Anfang 2015 geladen auf dem MacOS Monterrey läuft. Sobald ich einen eMail Account einrichten möchte stürzt Thunderbird ab. Was muss ich tun, um diese Abstürze zu vermeiden?

Just updated my MacBook Air to Sequoia 15.7.3. Since that update, Foxfire will open, but when trying to open an article in Foxfire, Foxfire locks up and doesn't wan to shut down even with "force quit." What can I do?

Good morning,

I want to install my account (GMX) in thunderbird on a mac book air (´11 2015 macOS Monterey 12.7.6) but thunderbird crashes every time, after I put in name, email and password and press enter.

Can anyone help me please?

Hi, Windows 11, 32GB memory. Firefox crashes regularly when between 1.6 and 1.9 GB is consumed It happens when watching YouTube. What is the solution, please? Thank you.

Hi - I'm trying to install Thunderbird on my mac to get away from a google workspace account. I've downloaded it a couple times and it crashes immediately after the login screen. Same thing in Troubleshoot mode. It's a work computer so it might have something installed preventing the desktop app from working. Thanks for any help you can offer.

Firefox crashes whenever my computer goes to sleep. I am running windows 11 and have been for years. This problem showed up a few months ago. The crash then screws up other apps and I have to restart my computer to fix it.

Hello, Here is what I consider a new bug in TB. It goes this way: While I am reading a message in the message pane of the standard window (not in its own window), if messages arrive (with a small ding for me), the message pane I am reading goes BLANK and the message I was reading is deselected. I have to reselect the message I am reading and scroll down to where I was. This behavior is very annoying and did not exists in previous versions.

I hope this helps. Thank you , Alain Damlamian

I've been using Firefox all morning. Now, for some unknown reason, every time I start it up, it immediately crashes Windows. I mean, within 1 second or so. There's no time to do anything. After the fourth crash in a row, I just restarted Windows again. It was humming along happily for 10 minutes or so, and then crashed as soon as I started Firefox. After the first crash, the first thing it did was update, but that didn't fix anything. I'd love to share data with you but I'm forced to use Edge right now.

Right after typing my email address and pressing "Continue", Thunderbird crashes. I wanted to give it a try after many years of not using it, but then it crashes right at the start.

Here's the crash report:

Over the past 2 or 3 weeks, I've noticed that firefox tabs are crashing more often out of nowhere.

https://crash-stats.mozilla.org/report/index/4a42f4cd-2203-40ba-a40c-616590251210#tab-details

Here's one of the links for the most recent tab crash. Other crashes pretty much were all the same. I can't read or understand this, so I was hoping someone who can is able to tell me what is wrong.

I fear that it might be hardware related, as I've had tabs also crash on Edge and on a new install of Firefox Developer Edition (which I downloaded simply to test if things crashed there as well.) I've also noticed programs like Discord & Elgato Wave Link sometimes randomly crashing as well - but I'm unsure how to pull logs for those, Firefox was the easiest.

My laptop's hardware specs are as follows:

Lenovo Legion Pro 5 - 16IRX9 Processor: Intel Core i9-14900HX (2.2GHz) Installed RAM: 32 GB GPU: GeForce RTX 4070 Laptop GPU Windows 11

If you need more information, please let me know.

Here are some previous crashes that I've reported as well:

Thunderbird 145.0 (64 bit) with Windows 11 Pro.

In the message editor window, new message or reply or forward, when I want to insert a hyperlink using either CTRL+K or via the Insert menu, a popup window to insert the link into does not appear, and the write windows hangs. Becomes unresponsive. The only way to close it is by ending the task in Task Manager. I notice a crash helper in the Thunderbird group in Task Manager. Everything is on 0% CPU though.

What went on before this is that I modified the property editor.link_color in the config editor (because links are not readable in dark mode, but that's a different story). I then did reset it to default and restarted TB, then pc and TB, that did not help.

In troubleshooting mode, there is no problem. In normal mode, I deleted the only plugin I had (a theme) I cleared cache, refreshed Thunderbird, to no avail. It's not set up to generate crash reports yet.

I have TB on another machine (W10 Pro), I can copy my profile folder over quite easily.

Any suggestions please?

(I'm on Central European time, it may be a day or so before I respond to replies from the US.)

Hello,

I have today encountered a reproducible issue with Firefox 145.0.2 (64-bit) on my system (CachyOS Linux). Whenever I press the "Print" button in the printing dialog for a PDF file, the browser freezes and no longer reacts to anything. I had to kill the process manually and try again. I have then downloaded the PDF and opened a different application to print it - that worked fine. Is this a known issue with Firefox? Does anyone have an idea how to fix this?

I already tried resetting the printer settings in the browser, but that did not change anything.

Thanks, Stefan

For about 2 weeks, EVERY time I try to write an email, after typing a few lines or so, the whole window 'grays out' and becomes UN-responsive. I get no error message. Waiting for it to respond doesn't work and I have to close out and re-start Thunderbird. Sometimes Thunderbird will have saved some portion of my email in my 'Drafts' folder, but not reliably, so I have to frequently 'Control + S' - save it to avoid having to re-type the entire message again. Troubleshoot Mode doesn't help, nor does clearing the cache. I've been hoping an update would come up that would solve this, either from Thunderbird or Windows (11), but not so far. Please tell me how I should resolve this - I have used Thunderbird for years (and regularly contribute too) and don't want to have to change to different email client.

Confused. Version 144.0.1 | Released October 16, 2025 Says 32 bit. I thought I downloaded 64 bit.

Problem: Freezes when I click anywhere on TBird desktop

How do I address the freezing problem?

Thanks Robert
