T-Bird is Freezing (Hang?) from start to freeze was 5 minutes and a few seconds. Have turned off hardware acceleration and now it freezes at just under 5 minutes. Have put on updates. Currently 153.0.1esr (64-bit). I have captured profile, and re-installed and picked up the profile. Still freezes. Turned off AV. Still freezes. I have compressed and "repaired" all folders. Still Freezes. I forced folders to get rid of anything older than 30 days. Still freezes.

I have been running the task manager, and T-Bird in frozen state is only using 4.3% of CPU at most. I do not see any slowdowns for any other program. So this is not a CPU constrained problem. And it certainly is not memory constrained.

All this started within the past month and I think it was after I put on an ESR update (don't remember which one).

I can kill T-Bird and start it and it will get mail if any, and will function for about 5 minutes and then freezes (or hangs). The system is set to fetch mail on start up and then every 27 minutes. I am not using Account hub (and don't know what it does).

One oddity -- This is a W11 Home system, and Mozilla keeps saying it is a W10 system. Could this be the problem? Wife is running a lesser laptop. It is also running T-Bird, but her O/S is a W11 Pro and she is not having this problem.

Hello Folks, We are a team of 15ppl using thunderbird from last few year and it work flolessly in these years but from last 1week i have been facing a serious issue of : INCOMING EMAILS TAKING A LOT OF TIME TO OPEN AND READ, fresh email when received and after clicking it takes a lot of time of open, having a 100mpbs ILL speed, out of 15 / 12 ppl are facing same issue, even after repairing the inbox the issue remains same, mails are getting downloaded very slowly...we are using google imap server for the same, need help to resolve the same...is it the bug in the latest update 153.0.3 (64-bit) Meadow badge

I have had Thunderbird from the time I acquired my Mac computer. This week it started to do something new. After a restart I opened Thunderbird. A box came up that says across the top System Integration. The cursor balloons, and hasn't stopped for the time I powered the computer, as least fifteen minutes. You know how the program icons are in a dock across the bottom. With other browsers open, hitting the Thunderbird icon doesn't bring its window into the forefront. This needs either a reset, or possibly a backup first. Is there a quicker way to fix this? Thanks in advance. I am not using a VPN; but I also have Thunderbird on my Windows 11. You might have seen a more recent thread on that installation. I included a screenshot. It was easier here to do that than on the Windows 11. On the Mac, I just had to use Activity Monitor to close out of Thunderbird in order to get its version.

I've done EVERYTHING.

New install of latest version. edited profile to point to saved data on USB external drive DELETED every instance of lock files terminated task numerous times. rebooted 3 times...

What now???

Hello,

Every now and then Thunderbird pops up the notification in the screenshot. Can anyone tell me what it means and if I should do anything about it?

Alan.

hi :-)

My Thunderbird uses between 19 and 34 GB of RAM. It's cyclical (with a period of about 10 minutes).

What do you suggest?

Do I need to perform a performance diagnostic? https://support.mozilla.org/en-US/kb/profiling-thunderbird-performance

Do I need to follow all the steps listed on https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems#Diagnosis_Steps, or can I skip some of them?

I am using Linux Mint Cinnamon 21.3 and Thunderbird POP3 email. I have 10 email accounts.

What I have noticed is the Thunderbird 128 series startup email check and/or "get all messages" is quite slow compared to previous versions.

Thunderbird 102.15.1 took only 4 seconds to check 10 email accounts, Thunderbird 115.18.0 took 5 seconds, but Thunderbird 128 and 136 series takes 15 seconds. All of these have used the same user profiles.

There is no antivirus software active. All messages are deleted from all accounts. No messages to download and checking for messages is still slow.

I have tried the Betterbird 128 series, a fork of Thunderbird, and it too behaves the same. Betterbird 115 series work fine, just like the Thunderbird 115 series.

Is this slowness in the 128 and 136 series by design?

Every time I shut down my Windows 11 PC (25H2, x86-64), it gets stuck and states "This app is preventing shutdown", listing Thunderbird as the application that is the cause for the hold. If I don't react to this and force close Thunderbird at this point, my PC does not shut down. (Annoying if I hit "shut down" and walk away expecting the shutdown to complete.)

If I close Thunderbird before shutting down, Windows proceeds correctly.

How can I diagnose why Thunderbird seems to hold Windows active?

Whenever I have just 1 Window of Firefox and just 1 tab open, task manager ALWAYS shows 14. Why is this? I have refreshed Firefox and lost some of my settings, it did nothing. Have I been hacked and someone else is controlling my browser?

Screenshot shows one firefox with one tab and yet 14 next to it in Task Manager

I recently moved from macos to linux and noticed that Thunderbird always reloads one account on startup -- by that I mean that, when I open TB, three out of four accounts display immediately, but the fourth one takes a moment, and then all its folders start appearing in the left-hand-side column. I had a look around and saw something about the .msf file being broken, with a solution being to delete it and let it be rebuilt. I headed to my profile folder but I now see that, in the ImapMail folder, the three accounts that appear immediately have their respective folders and .msf file, but not the account that reloads every time. I tried clicking on "repair" on the (unified) inbox, I tried checking the settings, but am not seeing anything that helps. Any ideas?

My Firefox is set to auto-update and did so Wednesday night, so it's currently 152.0.1 (64-bit). Since then, it’s been virtually unusable on my home computer (a 2017 iMac Intel Core i5 running Ventura 13.7.8).

I’ve changed nothing about the way I browse, yet having multiple tabs open at a time makes the application either non-responsive and I have to force quit or makes it crash (from today: bp-3c95c176-fde2-40e4-a61c-c5c080260619 bp-7ebe2fc9-0be2-4db2-b0e3-675df0260619 bp-bfe86698-eaf0-4cd2-96c3-ed20b0260619

It crashed four times yesterday as well, but I inadvertently submitted ALL previously un-submitted crashes, so I'd have to dig through to find ones from June 18th).

I can't get most websites to load. I cleared all my browsing data this afternoon in the hopes that it would help, but now I'm having trouble logging into sites like Facebook, Instagram, etc.

Videos on any platform will not load, let alone play. Instagram, YouTube, Peacock (which I think was having an outage last night), Twitter, BlueSky, etc. YouTube BRIEFLY loaded and played a video last night but there was no audio. I tried searching a word’s pronunciation in Google, no audio. It will not play audio on any music sites (SoundCloud and Bandcamp; they both show that the music is playing, but the indicator bars do not move on either site, and again, no audio).

I believe this is an update issue because work computer (MacBook Air, 2017 running Monterey 12.7.6) is using Firefox 151.0.1 and everything is working as normal there (fortunately I leave Firefox open all the time on that computer so it hasn't auto-updated). It had also been running fine BEFORE the update.

Any ideas on a fix?

All folders are shown ticked but they do not appear. I can view one folder at a time with Go>Folder>my account>Inbox(say).

Using IMAP. Firefox 151.0.4 I don't know what I could have done to cause this.

Hi all,

I've been using Thunderbird for eons but yesterday morning it started freezing up constantly.

It freezes up ("Thunderbird is not responding") every time new emails are received or any time I take any action while the Inbox folder is open. So, if I delete an email it freezes for a few minutes. If I do anything pretty much, it freezes up for a few minutes. Then it comes back and I can do another action, and it freezes again. This only seems to be happening when I have the Inbox open - if I go to other folders it seems to function normally.

Things I've tried without success: - Troubleshooting mode - Adding exceptions for my profile folders to Windows Defender - Compressing Inbox (and Trash and Junk) - Repairing the Inbox index

This doesn't appear to be a memory issue - right now, memory use for my entire system seems to be hovering at just over 50%. But Thunderbird is still freezing.

My Inbox folder is very large, but it's never been an issue before and nothing significant was added yesterday when it started failing.

Any suggestions appreciated!

Thanks

I have 2 Windows 11 laptops running Thunderbird. Retrieval of POP3 account email takes 10 times longer on Windows 11 as compared with Windows 7. I have 13 different email accounts. If there is nothing new to download, my windows 7 computer takes 5 seconds to check all account. Windows 11 takes 50 seconds for the same task... clunking along very much slower. I have tried many approaches to tracking down the cause of the slowness. Antivirus software (Norton 360) and various Thunderbird and system settings. Nothing makes any noticeable difference. I'm at a loss for what to try or even to finding anyone discussing the same issue. I have been using Thunderbird on at least 4 windows 7 pcs with no such issue. Both my windows laptops have the same clunky slowness. I want to move to windows 11, but this is holding me back. Is this just inherent to Windows 11? Any ideas would be appreciated. Thanks

I have several Windows 7 computers running Thunderbird and have 13 POP3 accounts to retrieve. These computers work fine. It takes about 5 seconds to check all 13 accounts if there is nothing new to download. I have two Windows 11 computers that take about 50 seconds to go through these same accounts under the same conditions (nothing new to download). I have done a lot of searching for answers, but nothing helpful has come up. Any ideas on what might be causing this? Seems like it would be a common problem as both Windows 11 computers do the same thing. Both are Windows 11 Pro. Thanks for any guidance.

TB has started to exhibit terribly long latency lags

I'll be working on TB, and then it hangs for 5-10-15 seconds, if I click on a new feature, the screen goes gray until the latency resolves. Also get the Windows timeout error notice (see image)

After 10-15 seconds, TB resolves on its own and works OK for a little while, but then goes latent again after maybe 1-2 minutes. This is consistent last couple days. I've rebooted, cleaned caches, etc.. and the rest of the Win 11 PC is working fine, fast, no latency in any other program.

I asked my email providers if they were having IMAP issues, but everything OK on their end.

Ideas? TB v. 140.11.1esr (64-bit)

Hey there since a week when I brows with Firefox on Windows desktop the RAM uses jumped from around 60% spiked to 92-95% RAM and that changed just come a long a week ago. If change brows like Chrome different story, back down at 65. So you can also see a massive number on Firefox system running.

Question: Whats the reason for the change? What happend?

Best, Janosch

I just wanted to point out that the browser on Android has too many processes running in the background—I’ve never seen anything like it before, and it doesn’t seem normal to me. I’ll attach some screenshots of the processes on my phone.

Once I delete a message, T-bird (147.0.4 on W11 Pro) begins compacting, and then I'm stuck until it's done. This is new behavior. Previously the system compacted occasionally, but now it's every single time I delete something from the inbox (which happens frequently during the day, of course, sigh).

Anyway, many thanks in advance for help/guidance and if it matters, I'm one of those who contributes monetarily for use versus freeloading. Also, no, we don't believe updating to the latest version is productive for our situation so I hope this is not the solutuion. -- Regards,
