Unable to open the summary file for [Gmail]/Sent Mail on myemail@gmail.com. Perhaps there was an error on disk, or the full path is too long.

I am plagued with this error message on various accounts. The folders have opened before and it exists on the Gmail website application.

The SSD is fine with plenty of available space. Over twice needed by the system.

The profile folder is 65GB. Can Thunderbird handle that much data storage?

This appears EVERYWHERE: emails unreadable (blurred). BUT if I select (left-button + mouse movement), a whole section (NOT the whole message) becomes crystal-clear. I have saved many such incidents, but one is below:

I am having severe problems downloading and syncing my emails with TB 142.0. I opened TB this morning, for example, and it took more than 20 minutes for it to download my emails. When I go to the next email, it takes a couple of minutes to load it. I have had some issues with slow syncing before, but this is very bad. I note that the emails work fine on my phone. Also, this happens on my main Gmail hosted account, but also on my other Siteground hosted accounts. TB seems to be lost in some kind of loop when syncing.

Under no circumstances is thunderbird loading a profile (existing or newly built).No crash report. Completely empty. New installed program and/or new installed post boxes + copied Mail-folders from existing profiles into a new profile will work once or twice or a few more times. At least next day TB starts only complete empty. I tried to fix it many times - using corresponding different forums.

Hi,

I'm on a fresh Windows and the CPU usage is waaaaay too big. When TB is out of focus, it uses about 10% of my CPU. This can go up to 15% when the window is active. It's not doing anything, not downloading or compacting or anything.

Thanks !

I've been using Thunderbird for many years, and its up to date. I've had more and more problems with choppy response times lately. It "freezes" for short periods where the interface stops responding for half a minute, or a minute or so before I can do anything. It always comes back (never crashes, shuts down). Today was some of the worst where it was minutes before I could start using it.

My junk and trash folders are empty, and I've done a compression and run the cleanup operation on a bunch of folders. My Inbox is empty. I only have 2 pop accounts. Its not when its retrieving or sending email though.

Imagine having more than 30 Accounts to be added on a single profile my concern is how will Thunderbird handles file size if it's using one file (MBOX) and if the file has no solution, can I create files and keep mails on them until they reach max size?

Hello,

I habe been using Thunderbird for many years and I always considered it was a wonderfull software. But it seems that since Thunderbird revisions 128 replaced revisions 115 XXX, this software became less performant and less reliable than before: very (too) often it takes a big time just to open a received e-mail, it is longer and longer to send a new e-mail, even without attached file. Sometimes the software seems locked: nearly all commands are unavailable, in a "grey" state: "the program does not respond ..."

Somtimes, when you run Thunderbitd you see a huge disc activity, as if the software was re-indexing the databases after each launch.

Even if you re-install the software, from scratch, and you re-index all the files the behaviour does not improve.

Theses problems have begun since revision 115 XX was upgraded to 128. We have been told that Thunderbird sofware had been widely "redesigned" but as a result, right now, it is less good than before.

Looking on forums I see that I am not the only one to signal these problems ...

Can you give us some more informations about what is going on with Thunderbird ? It is going to be "stabilized" ? Does this last major evolution of Thunderbird is going to arrive to a more stable state ?

Thank you by advance.

Regards

Thunderbird 128.5.2esr (32-bit) Odd problem in that just one folder was being identified as not being able to be compacted because of Disk Space....not true, plenty of space as I keep it regularly cleaned. I can clear the issue by making another folder of a different name, copying all messages to that folder then running COMPACT on the new folder and nothing is amiss. Run it on the original problem folder and no issues. Delete the original folder and create another with the same old name and transfer the messages to the now new originally named folder. Delete the TEMP folder. Then run a COMPACT on the problem folder and no issues.

Then run compact on the whole message tree and sure enough the COMPACT issue has now moved to a different folder. I suspect you could chase this thing till the cows come home but won't resolve, just moves it from folder to folder.

Now I could just kill Thunderbird and reinstall but this is intriging. Not sure if that would help. Ran TROUBLESHOOT MODE clean with out the only extension I use and no change. Stumped.

Thanks!

I've been using Thunderbird for probably 10 years or more. My current version is 140.1.0esr (32-bit) - unsure when this was updated from previous version. My pc is a 64-bit pc so I'm unsure why I'm running the 32 bit version of Thunderbird.

Starting today, when I click on the New Message button, nothing happens except the button seems to register the mouse click with a slight change in appearance. Usually this would open up a blank email but I currently can't write a new email until this is resolved.

Turning off Anti-virus makes no difference. I've tried a PC restart also with no effect.

Any ideas what I can try please?

I'm using Thunderbird with a Gmail account (amongst others).

Recently, something has changed, and Thunderbird now re-syncs with my Gmail account every single time I start it. It's a big account and this takes a very, very long time; and is very slow.

I do want it to sync, but only to get new messages and delete old ones.

It's almost as if the mail is not being stored locally, but I have ticked 'Keep all messages in all folders for this account on this computer' for this specific account.

Would appreciate some help, please.

Thx

Greetings!!

I started getting the most bizarre problem over the last couple of days from Thunderbird. Suddenly, for certain emails (not all of them), Thunderbird will start truncating the email. The email just stops loading partway through, and the email is not marked as read as it usually is. There is no progress bar at the bottom to indicate that the email is still loading. But, if I view the message source (via the View menu), the whole email is there. It typically happens with emails with either images or ones that fetch some sort of dynamic content.

I've repaired folders, rebuilt summary files, removed parent.lock, restored a backup of both program and message files from two days prior to the problem starting, reinstalled my current version of Thunderbird, rebooted the computer by holding the power button down for a minute, tried Thunderbird Troubleshoot mode, tried Windows 10 Safe Mode, disabled all add-ons, cleared my cache (under disk space), cleared my startup cache, created a new profile, compacted folders, and (temporarily) gave it a free pass through my Firewall. Nothing had any effect.

The Thunderbird Error console doesn't show anything in particular different between emails that load fully and those that do not.

To say I am at my wit's end is an understatement. Is there some sort of simple solution I am totally missing, by any chance? Thank you for any assistance!!!

Using v128.14.0esr 32-bit with 6 accounts checked every time - and got this update just a few days ago, not sure what precious versions were - it says though that a v140.3.0esr is available, not sure why I got update v128 that is not the latest

I was used, for more than 12 years, to just start Thunderbird to check if any new emails, and then close it again if none. - was done in 2s

Now every checked account take like 2s and have to wait 12s to close TB again. - yes, you see three messages every account checked, maybe some want that

I would appreciate a setting to empty/check as fast as possible as before, or this new approach? - a simple checkbox, fast check or not

Or is there a way to revert to earlier versions to restore this? - or some registry or setting elsewhere to alter? It's very inconvenient with this serious delay each check feature?

Thanks for reading. Would love to hear how community feels about this too?

I have been having much trouble with Thunderbird. The latest problem is with the Sent folder. When I try to Compact Folders I get the message "The folder 'Sent on Local' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again."

I have plenty of disk space and have Full Control. I tried creating a temporary folder and moving all the Sent messages to it, so that Sent had zero messages. I still got the same message. The file listing showed Sent to have a size of 182 MB even though it didn't contain any messages. I've tried deleting sent.msf to force Thunderbird to recreate the index - didn't work. I tried using Repair Folder. That worked, but when I tried Compacting Folders again it found another folder with the same problem. I fixed that one and then it said the Sent folder was bad once again. I'm going around in circles!

I've deleted and recreated scores of .msf files for various reasons, trying to get Thunderbird to work without errors, but as soon as I get one problem fixed, another one crops up. I'd conclude that it's my computer, except that I'm not having any problems with other programs.

Any thoughts on this particular problem or Thunderbird problems in general? Thanks.

A few days ago, something happened to the Firefox browser. The speed is simply terrible, sites are loaded for several minutes. Reinstalling does not help. Other browsers work fine.

Hello:

My Windows Thunderbird has become unresponsive, taking forever to connect to my various accounts. I suspect the problem is with my GMail account--which is not my primary account--is causing the problem, but I am unable to un-sync GMail's All Mail folder.

I was able to get into troubleshooting mode, but TB was still unresponsive.

I have copied the profile in question to my Linux machine, with TB V140.4.0esr, to try to repair the profile, but the problem is recurring there as well.

Is there a way to manually edit the profile file(s) to remove the GMail account from Thunderbird?

Any insights would be much appreciated.

Thanks

Firefox kept eating my RAM, running dozens of processes. I have gone into about:config and set the dom.ipc.processCount to 1 - then I restarted Firefox and found 5 processes running straightaway before even using the browser. I closed it down and have started it again and now there are 11 processes running with just one tab open. Firefox(9044) Utility(7552) JavaScript oracle Network (15912) Data Decoder (11364) GPU (18744) About pages (12536) Preloaded new tab Extensions (20544) Preallocated (16132) Preallocated (13780) Preallocated (16044)

The problem repeats on three different computers which are not infected with malware. One computer with slightly less RAM I now cant even use Firefox at all (though all other browsers work fine) because the tabs constantly crash due to the high number of processes. Is there any way to set the process limit low in a way that Firefox actually responds to?

Config editor has no printer listed. nothing to reset. Printer works with other applications just not TB. Re-installed the printer. Reset the space limiters, which I found were set too low. Restarted TB and computer

I am running Thunderbird 128 (any version) on a Surface Pro 9 running Windows 11. After sleep/hibernate or going into energy-saving mode, TB hangs for a period of minutes. Eventually it comes back, but it can take 5-10 minutes.

I do not have this problem with TB 115 on the same machine, or TB 128 on other machines (e.g. running Windows 10 or Ubuntu). TB 115 on the same machine can take a few seconds to come back (longer than on my other machines), but that s OK.

I have the same expereince whether or not I am troubleshoot mode. I have created a new profile with no add-ons (and less acounts) and I have the same problem. I was wondering if it is something to do with the fact that I have 8000 folders, and somehow TB is hanging while it checks all the folders. That account is a fastmail IMAP connection, but I have experienced similar on a backup Microsoft Exchange account (again an IMAP connection) with similar number of folders.

Any help would be appreciated.
