My Thunderbird (version 115.12.2) is running on a Windows 11 system. My profile has multiple accounts configured as IMAP to multiple email services. I also have the Status Bar and Activity indicator enabled. Randomly, both indicators will show busy for an extended period of time. When I view this in the Activity Manager I see one or more folders hung for 10 or 20 minutes downloading one message out of several. This occurs in multiple accounts and servers.

I have researched this and attempted the fixes presented. I have cleared the cache files and compacted and rebuild email folders as suggested, but the slow update still occurs.

Then I decided to try and capture a ProMon.exe trace to see what is happening. What I found was Thunderbird.exe was spending all of the time while hung access the following file: C:\Users\MyUser\AppData\LocalLow\Intel\ ShaderCache\4a5eb0e65e559fc08e65ecb2fa9d650817ae895582a7a7ede162866d3e47a05a, like it was stuck in a loop.

When Thunderbird is operating normally, it is accessing this file but only for short period of times. Research says that it is ok to delete the files in this folder. I did that and it seemed to help for awhile. But it started happening again.

Does anyone have any idea what could be causing this? Is there a Windows thing to look further into? Any help would be greatly appreciated.

При заходе на сайте ya.ru и если на нём имеется строка с видео или поиск с алисой, то начинаются сильные фризы. Это ошибка именно в firefox 142, проверенно.

Hi to all.

I've had one of my TB configured email accounts disabled so I cannot login to it. How can I avoid TB to show me again and again that it's not able to connect that account? I just want to keep the already received/sent emails there in TB but it goes on and on showing that message even if I don't work on that account via TB anymore.

I've tried to unflag the option to check new messages from the Server options, but it didn't work. I've also tried to move all the emails/folder on local folders via TB interface, but this was made just partially possible because TB tried to login possibly due to some still-not-downloaded old messages which where made impossible to move. Moving all to a local folder will let me delete the account from TB and set me free from that annoying message which is also causing TB to be resource consuming, I don't know why, so that the laptop fan goes crazy (in such case, quitting TB causes the laptop fan to be back in peace in seconds).

Thanks. Regards.

Upgraded from Windows 10 to 11 a couple months ago. Since then, TB freezes nearly every time I am composing an email. "Help About" says TB is up to date. Remedies? Or do I have to wait for a new version?

I don’t remember from when, but after some point of an update of Firefox for iOS, whenever I type something in Korean into address bar for quick search, it automatically changes my inputs to English and extra character appends at the front. This will cause great inconvenience for Korean users. I hope Mozilla team fix this problem soon.

I am getting sick and tired of Thunderbird freezing while writing an email, screen graying out, and having to close the program and lose the material without it having been saved in any way. This has been happening for two or three weeks.

Hi all,

I have found a bug with version 10.1 of the Thunderbird email app for Android.

When I go to Sent Items in the Thunderbird app, choose a previously sent email to view it, then choose 'Edit as new message', then make the necessary changes and choose 'Save draft', Thunderbird crashes and the new message is lost (not getting saved in drafts).

I used to have the https-only mode on, but I have since turned it because I'm unable to hit an http only site. However turning off this setting does not work. After disabling, I have tried disabling all extensions and forced an app restart, but I'm still being forced to https for a site I'm trying to use http for. I am not being forced in a private tab, so this makes me think that disabling https-only doesn't work anymore...

Just what it says. Using the latest version of Thunderbird on Windows 11 Pro.

I have had my usa.net account use the same IMAP settings forever; I double-checked my settings and they are correct.

Now, I get a LOT of email on that account -- I typically download it when I hit 10K messages. This usually isn't a problem.

I tried moving all of my current Inbox (already in TBird) to my archives. I was then able to download about 1K messages and then it stalled downloading. Said I either didn't have write access to the disk or had a file permission. I'm not seeing anything on the web interface for usa.net on this.

Now, I have 3 other IMAP accounts on T-bird -- 1 is never used (default from my ISP), a 2nd is very light traffic (mostly I stick with that email provider because they are small and still have private shell accounts) and the 3rd is my business vanity domain--high traffic but not the same as usa.net (where I get ALL my receipts for any online purchases, daily newsletters, help forums, etc).

Any idea what may be going on? Please be kind; I am not a programmer, just a more tech-savvy than the average bear (as in if IT is busy at work people ask me for regular stuff).

If any more info/filedump stuff is needed to see what's going on, please do let me know and I will tag it up asap.

Thanks again, community!

For years, I have been routing all my Gmails through Thunderbird very seamlessly. Then my computer crashed.

Nothing on my hard drive was retrievable...so I had to download Thunderbird onto my new computer. I then proceeded to move all my Gmail to this newly downloaded Thunderbird. I had many different files in Thunderbird on my old computer, so everything was tidy and easy to find. When I opened Gmail after losing my old computer, I was relieved to see that the files, and the way I had them organized was the same. So, I assumed it would transfer over to the newly downloaded Thunderbird that way.

However, when I moved all my Gmails to the newly downloaded Thunderbird, all 3200+ Gmail emails were lumped into Thunderbird's "inbox".

What can I do to get everything back into their folders like they were before?

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:

Hi -- I'm getting quite a few page crashes that seem mostly tied to YouTube, although not exclusively. I only recently swapped over to Firefox from Chrome because I was having similar crashing issues with that browser as well. This is after a fresh install of Windows 11 Pro and a number of different benchmark tests (no known issues with CPU, GPU, or RAM).

Since there are so many reports that all seem different, could someone help troubleshoot? I really can't tell if it's a browser problem, maybe something with my MOBO or PSU or other hardware.

Every time I want to print an email, the default copy number on my printer menu is shown as 2.

I don't know how, when or why this change [from 1 copy to 2 copies] happened.

I wish to 'reset' the default copy number to 1, so I don't accidentally print a second copy and waste ink, etc.

When I want to print documents stored on my PC, the copy number field on the printer menu is blank, allowing me to enter the number of copies I want - so the issue appears to occur only when I print emails.

I have to add a office365 accounts. Everthing works, until Microsoft's popup window requires to sign in to MS 365.

When I click in "Sign In", nothing happens. The button becomes light blue for some seconds, then turns back to blue again.

The credentials are correct, there is no error message, nothing.

Probably a problem with the popup browser window?

Javascript is enabled. Anything else that could break this?

I've been searching for a few days for a solution to Yahoo Mail not downloading to Thunderbird, I've seen other people with the same problem, I've tried different solutions, but at this point I've given up. My Gmail is still downloading but I have to check my Yahoo Mail via a browser. What gives? Why did this happen in the first place?

I have Windows 11, I've updated Thunderbird.

I have have had a Gmail address for a few years and have just created a new Gmail address, I am trying to copy about 20,000 emails from the original Gmail IMAP folders to local Thunderbird folders as a backup, and then copy them to the new Gmail address IMAP folders.

I have tried copying these in smaller amounts as suggested (between 200 and 500 at once) This seems to go well, however, when I have completed the task the original folder has a much higher amount of messages in it than the new one, so some messages are being lost along the way.

Is there a reliable method to do this, such as closing Thunderbird and then copying and pasting data held in the profile folder, or does it need to be done with Thunderbird running?

Many Thanks in advance

I use Thunderbird to access my Hotmail account. I normally work on my Desktop Windows 11 system but have a laptop Windows 11 which I seldom access email with. When I just tried to update the laptop Thunderbird mail I eventually get the Thunderbird message "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox". There is enough free space on my drive and it succeeded writing 10522 messages before it came to a halt. I notice that the desktop is at 140.4.0 and the laptop is at 144.0.1 and help says they are both up to date.

Since the Desktop mail is up to date it would seem the quick solution is to replace the mail folder on the laptop with a copy of the mail folder from the desktop. Will this be a problem since they seem to be at different versions. Version 140.4.0 on the Desktop and 144.0.1 on the laptop.

Last night I updated my iPhone 11 Pro to iOS 26.1

Since the upgrade I'm unable to have Firefox play audio for a music stream I listen to when the phone goes to sleep/lock or if I use the app switcher to switch to another app, like Maps.

This wasn't happening yesterday when I was using my phone and listening to the same audio stream in my car with Maps open for navigation.
