Why is everything running so poorly? The right-click function does not work. I have also tried to use various features, but the drop-down menus are not accessible. I cannot even mark something as read. The right-click function continues to fail, and I was also having trouble accessing help or using the Help function at all. I had to close and reopen the program just to get here. Something has clearly been wrong in this regard over the past week or so.

The folder 'Outbox on Local Folders' 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.

Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks

Keep getting this message: "The folder "inbox on [email address]' 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 tons of space, but I don't know which folder you are referring me to. Does it have a name? Does it reside in a specific subfolder? Can you give me some hints to locate the folder? Is this really the problem, or does the message indicate something else is amiss.

Thanks, Don

I am experiencing a severe problem with Thunderbird. There are several symptoms: 1) The CPU utilization of Thunderbird is typically 13-19%. 2) Thunderbird declares that it was able to send a message and to save it, but that it experienced difficulty when running filters. 3) Thunderbird is unable to compact a folder. The message received is:

   The folder 'Inbox on william.atwood@concordia.ca' 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.

4) Thunderbird occasionally gives the following error message: Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. You can retry or save the message locally to Local Folders/Sent-william.atwood@concordia.ca.

These are the symptoms that I see today. Over the longer term, I saw the following:

1) Thunderbird started to behave strangely several weeks ago. It somehow lost track of what messages it had downloaded, so it started downloading all of the message headers in my inboxes (and other folders). (I have six email accounts that I monitor.)

2) Since all of my accounts are IMAP accounts, with the messages stored on the server, I tried replacing the Thunderbird profile with a copy that I had previously backed up. This seemed to solve the problem for a short time. However, the symptoms soon re-appeared, including high CPU utilization, inability to compact folders, and difficulty running filters.

3) At the suggestion of my employer's help desk, I removed and re-installed Thunderbird. This found the existing Thunderbird profile, and everything seemed to work just fine for a few days. Then, suddenly, everything went haywire, and Thunderbird started re-loading all of the message headers for *all* of my folders (and for all of the accounts), and complaining about inability to run filters or compact folders.

Finally, Thunderbird crashed today. I added notes to the crash report, giving some of the details above. After it restarted, it crashed again. I finally ended up restarting my computer.

Thunderbird version 140.0.1 Windows 11 Edition Windows 11 Enterprise Version 24H2 Installed on ‎2025-‎04-‎30 OS build 26100.4349 Experience Windows Feature Experience Pack 1000.26100.107.0

What can I do to mitigate this problem? It is very difficult to use Thunderbird when it acts like this.

Hi. I have over 20,000 messages in my Inbox. I've been sometimes having trouble moving messages into folders, so I thought it would be a good idea to reduce the number of messages in my Inbox. But I can't delete or move messages in the Inbox. When I select messages and enter command to move them to a folder, or ask to delete them, nothing happens. I am a Thunderbird supporter, and I love this program. Thanks for your work! Any advice appreciated. Connie

Here's the error message:

The folder "Inbox on tomhelm@sonic.net" 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 think I have enough disk space. But how do I verify that I have write privileges to the file system?

Hi,

When switching from FF 128esr to 140esr our customers noticed a massive impact in performance for certain webapplications. All Applications effected heavily use pdf-files, users are working mostly exclusive in firefox. Performance is ok when the day starts but gets bad fast. Sooner or later working is no longer possible and firefox needs to be restarted.

The users work on Citrix Desktops, but difference in performance is also seen in Firefox localy (not as bad but its there). Cross-tests with another browser are not possible, because the application works only in FF.

We tried removing almost all policies effective to rule out a specific hardening setting We tried every setting we could find linked to cache (as it seemed related to that) but without success. We collected logs with the Firefox-internal Tools but could not identify a specific Problem.

Any Help is apreciated, thx in advance

I've been using Firefox for a while, and while there are many things I like about it, it has always been a resource hog. In the past I could get around this by just killing Firefox in Windows Resource Manager and restarting, but ever since getting a new computer an upgrading to Windows 11, it's gotten worse. Every couple of days my computer freezes for 10 or more minutes, I'm having to do a hard reboot ever few days, and I'm even bluescreening about twice a month. I'm pretty sure Firefox is the culprit because killing it will usually resolve the issue.

I'm wondering if there is some way to put Firefox in a sandbox so it does not consume nearly all available memory and other computer resources. It is by far the biggest consumer of resources on my system and I do not want to dedicate 4GB+ of memory to an app that is just showing a couple of web pages and playing YouTube videos.

I use Thunderbird on Windows and on Mac. I'm wondering why the startup time on Mac is significantly longer on MacOS. I'm currently on Tahoe 26.0.1 but Thunderbird has always been a slow starter. Can I change any setting to remedy this. At the moment I have two mail accounts configured both Gmail.

I have only 4GB RAM and that can be an additional factor that causes this issue. When I listen to Youtube Premium in the background (with video window hidden) and switch to Firefox, Youtube Android App is killed. Same thing happen with Youtube Music from time to time. For Youtube, I can workarund this issue by keeping video in Picture-in-Picture (PIP) mode.

I have been having trouble for awhile now with the preview pane not changing with a message archive, delete or even a new message arriving. The only solution I have found that works is to turn it off/on with F8. Have tried updating (currently on 140.6.0esr), unified folder debugging, and setting thunderbird to download complete message not in bits on AI suggestions. Doing same thing on laptop and desktop. Gmail, yahoo and outlook accounts. It seems to only happen when using the unified inbox folder. Cannot find any reports here in forums, but AI says it is a common complaint. Is there anything I am missing to try?

Thunderbird very slow to respond when opening the program. On opening any email it freezes for a couple of seconds resulting in a "Wait for the program to respond" or "close program message" . This also happens when performing any action in Thunderbird. This has been happening for the past two or three weeks. Can you tell me how to fix this or is it something you need to do to fix.

I have been using thunderbird for a few years now on win 10. Just had to buy a new win 11 system and successfully installed it. transferred my emails, folders and contacts and all seemed to work fine. Now I notice that once I leave it for a few mins, it is unresponsive with just a blue circle where the curser should be. I close it and re open and all is fine again for a few mins. I have tried turning off my antivirus software and disconnecting from the internet but still the same fault. Any ideas please?

a black box appears over the search box when mouse is moved over the tab. Tried in safe and troubleshoot mode. Box still appears only in white I did find an answer previously but reinstalled firefox and the fix was lost. Problem resolved.

Thanks all for looking.
