Thunderbird Community Forum

Starting over the weekend, I have been unable to load my Thunderbird messages, it just says:

Home - Mozilla Thunderbird (Not Responding)

I wait, but it doesn't load.

Could I have too much stored in my email folders on my pc?

What can I do to get it to work again on my pc?

Online web browser works.

I cannot get Thunderbird to launch. It acts like it is stuck on perhaps one account and circles keep spinning as if it never can get a few of my tabbed emails open. It keeps saying it "isn't responding." Since this began happening a few days ago, I've stopped the Thunderbird task through Task Manager, I've shutdown and restarted my whole system multiple times, I've updated to the latest Windows platform and made sure my drivers were all up to date... I can't update my thunderbird (if required) because I can't get in in the first place. I have hundreds of emails in multiple accounts under my current Thunderbird. I can't afford to lose all that history. I don't know which version I'm using because, again, I can't get the desktop app to launch. What do I do?

My email on Thunderbird no longer loads on my laptop. It's fine on my desktop. It just stays a blank screen. "No message found" it says. I have to shut it down and when I do it says "Thunderbird is not responding." Can you give me a step-by-step on how to fix this?

I have/had two different problems with the same results. In the first case I get the login window. I enter the password hit return and that window goes away and some times you can scroll to different opened emails before it says "Not Responding". The only action that works is to exit the app. Usually after a few days or weeks it will start working and does so for a few days or weeks. Lately the login window does not appear when the app opens and it displays the "Not Responding" message. It shows that it is "Loading Message". I have tried all of the options from the troubleshooting window and reinstalled Thunderbird with no change in response> Where do I go from here?

How do I deselect multiple folders selected it didn't happen until today and now I can't use thunderbird. There is no way to deselect multiple folder and I did not select that option need to move through different emails account and my local folder where I have emails sorted and I need this at I have emails pertained to forms I need to complete in order to submit request for pension. It work perfectly well yesterday prior to recent update. I need access to my emails

Was kann ich tun? Habe Probleme mit mozilla. Bei derAuführung der Programme Thunderbird ( ständig ) und Firefox ( manchmal ) kommt es zu Abstürzen wie Programm keine Rückmeldung, einfrieren so das keine Eingaben mehr möglich sind und ich jedesmal das Programm schließen und neu starten muß.

Thunderbird is installed on an iMac Retina 5K, 27" 2019 computer running macOS 15.7.6, but just this week, when it starts, it only opens a window with tabs and does not finish opening the app. The window shows the tabs, but they just have a bouncing dot from right to left, and anywhere I move the mouse on the window's control bar, I get a swirling color wheel. I restarted the Mac (no change), deleted the app and downloaded a new one, and nothing changed. Force Quit says it's 'not responding'. What do I do next?

T'bird 153.5.0 esr on Windows 11 25H2.

Main Inbox folder (using POP3) is about 13 GB

Thunderbird crashes and/or becomes unresponsive on opening. This happens in both normal mode and safe mode.

Typically, there first is this error message: "The account is being processed. Please wait until processing is complete to get messages." I click OK on that message, and after a while, Tbird becomes "unresponsive."

I've tried deleting Inbox.msf, but that didn't help.

Sometimes, I get this error: "Unable to write to the mailbox. Please ensure the file system allows you write privileges and you have enough disk space to copy the mailbox." There have been no changes in Windows accounts, so it seems highly unlikely that there is a permission issue.

The hard drive on this system has about 233 GB free.

Where do I go from here?

I received a message with a password-protected attachment, and opened it in Thunderbird (in Windows 11).

I found that the password I'd been sent did not work with the attachment. I inadvertently closed the Thunderbird app with the password prompt still open.

When I tried to open Thunderbird again it tried to load the attachment and then just hangs indefinitely. Using safe mode has the same result.

Please can you suggest a solution?

Thanks

Even when it opens correctly a message appears:

The certificate for mail.capsense.com is not valid for that server. Someone could be trying to impersonate the server.and you should not contijnue.

Today TB froze during start up. No problems yesterday.

I deleted global-messages-db.sqlite and restarted TB. Now it is frozen with a "Loading messages". Maybe it is rebuilding indexes and this takes a long time and I should be patient.

Maybe my In and Sent mail boxes are too big? If so, how can I safely prune them?

TB is becoming increasingly unstable for me. It was very reliable before about a month ago.

I doubt my AV is the culprit because AV has not changed today.

Thank you one and all.

Greetings,

I've lost the ability to receive e-mail, Suddenly Thunderbird just quits on me with no warning. Apparently I can still send mail but cannot receive. This is the second time this has happened to me in as many months. How do I fix it? How do I prevent it?

Thanx

I have down loaded the latest version of Thunder Bird. The program still has my settings to access my e-mail. For some reason every time I try and read my e-mail the program locks up and I have to do a Task Manager to stop the program Any and all comments would be appreciated. Thanks Dave
