Since upgrading to version 115.8.1 I get unable to write email to mailbox . I have three email addresses in my profile. All are POP. One (from yahoo) always hangs and the other two fail intermittently. OS is Windows 10 64-bit at 22H2 level It doesn't matter if Zonealarm is turned on or off. I have over 300GB of free space on disk.

Full error 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.

Issue: The "Recommended stories" setting for the new tab default home page periodically re-enables itself.

Version Info: Firefox 124.0.1 (64-bit) OS: Linux Mint 21.1 Cinnamon

Additional Information:

• I do not use pocket, at all
• All settings that I can find related to pocket are disabled
• I do use Firefox Sync, however the other device (124.0.1 (64-bit) on pop_os!) does not have this issue
• Does not correlate to version updates (Mint has automatic updates disabled in policies)
• Does not occur after a simple restart

I am tired of disabling this setting and having it return seemingly randomly. I have no interest in these stories, and consider them spam.

Please assist me in determining why this is happening on this device and how we can go about preventing it going forward.

Thanks, Steven

I'm about the 100th person to have this problem, so I have spent the better part of two days looking at all the threads and possible fixes. Like all the others, with no warning, my TBird stopped being able to send messages through Spectrum. It did NOT start immediately after I updated TBird to 115.9.0 (in March) but just three days ago. I have three roadrunner addresses in TBird, and one other one associated with a website I have. All have the same problem. My phone and my iPad send messages just fine.

I tried all the fixes that worked for some. They didn't work for me; I continued to get various, inconsistent Send Message Errors. I have come back to the recommended Spectrum setup for the outgoing SMTP server: mail.twc.com, Security is STARTTLS, Port 587, Authentication is Normal Password, my username is my email address. Of course the problem is not fixed.

What DID work was putting TBird in Troubleshooting mode, using the Spectrum setup above. While that is adequate, I would much rather find out what is wrong. I have Matt's 10/7/23 11:56 AM answer to someone, asking for the Troubleshooting Information. I will be glad to supply that but I need an answer to this message in order to do that. Thanks! Demaris

When commenting on 9gag, the blue "post" button disappears. If I choose "Desktop sight", the entire page reformats and becomes different and I lose all of my posting information.

I have had message filters set up for a long time. Recently I tried to make some changes (adding one filter, deleting others, changing the response). I find that if I close Thunderbird and reopen it, all my changes are gone! How can I get the filter changes to stick?

I keep getting this message that pops up in a private window to restart to keep using firefox. Everytime I click restart Firefox, it closes my tabs and opens them again. However, 5 minutes later the window pops up again. Even after repeated attempts of updating, even doing a full restart on the computer, Firefox continues to send this window to me. The private window in the bar says about:restartrequired.

I've tried uninstalling Firefox with a fresh install as well as doing a Refresh of Firefox. Neither seem to solve this problem.

I'd been using 115.9.0 for a couple of weeks, and found it cantankerous, but manageable. Finally had the screen looking something like my old faithful 109. Today I started up Tbird, and NONE of the windows came up, except the main menu bar. I found that messages were downloaded (but I couldn't see them), and I could Write an email -- it's screen looked normal, as did the Address Book screen. I clicked on View/Folders and found that only the top "Folders" was checked. When I checked "All Folders", nothing happened, and if I left that menu and came back, the "All Folders" was not checked. Then I clicked something at the bottom of the Folders menu, and the Menu Bar disappeared. I've been unable to get it back. I enclose a screen shot of the current condition. Anything you can suggest is appreciated.

I am an e-mail packrat.... I have a pop e-mail but keep years and years worth of old e-mails (inbound and outbound) some with big attachments. My backup for the few e-mail accounts I have within my profile is approx 13 gigs. I've moved machines... and currently running Ventura on my imac.

I have to force-quit all the time to get my e-mail working again. It hangs-up.... sometimes will recover... but then... I type a few words or maybe sentences... and back to HANGING-UP again. Sometimes after a Force-Quit... it will behave for awhile. Other times... it takes 4-5-6 force quits in a row to get the program working again. Been having these issues for months... and have taken out all the add-ons etc.... HELP... pulling my hair out! Thanks

Yesterday I downloaded Thunderbird to Windows 10 (64-bit), added my Office 365 (for work or school) account, rocketmail account and iCloud account. I created unified folders for the three accounts. I have downloaded the TBSync add-on with the required CavDev (?) one to connect my iCloud calendar.

After successful use the first few times, now Thunderbird becomes unresponsive within 5 seconds of opening, every time, rendering the program unusable.

Troubleshooting mode does not fix the problem, so I assume it's not the add-ons, nor does starting my PC in Safe Mode (F4 at startup ie no networking), so I assume it's not antivirus.

I uninstalled Thunderbird and re-installed from the website today. All my accounts were there (so I wonder if the uninstall didn't work properly, although I assume that it's just the files left on my computer that the new Thunderbird installation is accessing).

All these attempted fixes leave the problem unchanged: the window freezing within seconds of opening.

Because the program becomes listed as 'not responding' and greys out on further clicks, I have to hard-close the program using Windows, selecting 'Close the progam'. Clicking 'Wait for the program to respond' leaves the screen greyed out, and nothing changes for at least 20 minutes (the maximum I've tried waiting it out). This also means that it does not yield a formal crash report, because Thunderbird does not recognise it has crashed.

On one occasion it did create a crash report, which I submitted. I am not sure what behaviour allowed this to happen, and I have been unable to reproduce it. That particular crash ID was as follows:

Crash ID: bp-41096385-eebe-4ccc-a47e-f76300240417

Any help much appreciated! I'd love to stick with Thunderbird if possible.

All of our "read" emails, --from all of our accounts -- have suddenly disappeared. All of the folders and subfolders are still present. We still get new email, but as soon as we read it, it's gone. We have had these same email accounts for years and have not made any changes. In Account Settings --> Synchronization & Storage --> "don't delete any messages" is checked. "Read" messages are still on our server.

So, 1) Why did this happen? 2) Is there any way we can get our messages back in Thunderbird?

TB v115.8.0 (64-bit) Closed the app and went to dinner Came back and opened the app. All the tasks are GONE!!!

I know TB keeps everything in text files, so I found the "calendar-data" folder and opened some files using NOTEPAD.EXE to find keywords I know represent my tasks. Sure enough, the data is there in the sqlite files.

What's the secret code that simply decides to not open those files and populate my task window?

When displaying an iframe video in a popup, clicking the close button and other click events do not work. This issue only occurs in the Firefox browser on Android, while it functions correctly in the Firefox browser on iOS.

Is this a default behavior.

Prior to about a month ago, downloading worked as expected: - click a link - the save to... dialog opened - choose the folder - the download is off and running

No more. For about the past month - click a link - wait for a long time with FF frozen - the a wheel starts rotating - after a full minute (or more) the save dialog appears.

Something has been broken in the mad-dash to push updates. It's fine for browsing, but the, you need to download. At that point you wish you were using a different browser (any other browser, in fact) since FF is the only oe that has this problem. Downloading works fine in a 8 chromium browsers that I have and in the 5 FF clones (like Waterfox)

It's just FF that's broken. I can no longer afford to set it as default because of this. The others are not perfect (WF won't activate Pocket, foe example) but downloading promptly is critical.

Thunderbird runs slow...ie when I type an email I can easily type faster than thunderbird will accept characters....(this does not happen in other applications)...this happened about a month ago, and then stopped ( I have no idea why)...but the problem is back. I am running Ver 115.10.0 build 2024012173147. Rebooting windows 11 makes no difference.... I just tried to enter Troubleshoot mode and thunderbird stopped responding....Top line says Mozilla Thunderbird (Not Responding). Thunderbird is connected to my gmail account. ...and I run IMAP....with 'store all messages on the computer', but thunderbird wants to load every email from the server'

Any advice would be appreciated Rick

I just got a chromebook! Details:

Device name: Lenovo Flex 3 12.2" chromebook, 8GB ram. Intel N100 Device code name: IP Flex 3 CB 12 (pujjo, version 123.15786.0) Firefox version: 124.0.2 (flatpak) OS version: Version 123.0.6312.112 (Official Build) (64-bit) Chrome: Version 123.0.6312.112 (Official Build) (64-bit)

When I watch a youtube video with chrome my cpu usage is 20-30% When I do the same with firefox my cpu usage is 50%

Running `about:support` and going into `webrender_compositor` I get the following errors under `env`: 1. Blocklisted by gfxInfo 2. Blocklisted; failure code 3. FEATURE_FAILURE_WEBRENDER_COMPOSITOR_DISABLED

I have set almost all these force renders = True and even granted gpu access to firefox flathub but still no difference in performance. I am asking now because I am just going in circles in the rabbit hole.

Hello,

I need your help because i can't find solution to problem. On my macbooks air m1 i experience a very annoying thing: Often while i'm scrolling on websites smooth scroll animation get choppy/sluggish for few moments and lagging. It's like animation is FPS dropping during the scroll. I tried lot of things on both device:

- tried without extensions - created new profiles - use without syncing data - disabling hardware acceleration (gets worst) - disable smooth scroll in settings (get worst) - completely remove firefox with AppCleaner and reinstall it - Reinstall macOS and just install firefox alone. I tried latest Ventura and Sonoma

I don't have clue why this happening but ruin user experience very bad. With Safari everything is fine and smooth. On my wife's device (macbook air m3) have same issue.

Do you have any idea how can i fix it?

Sending emails hit and miss. Sometime goes right out, other times I get this "The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. How do I cure this.. keep in mind I am very close to computer illiterate..

Symptom:

1. TB stopped downloading new emails for one account on PC.

Solutions Tried without success:

1. Checked Email configuration and settings 2. Restart TB 3. Rebuild Global Database by deleting global-messages-db.sqlite file. 4. Delete Saved passwords. 5. Delete all emails on webserver dating back to when problem began. 6. Change password on webserver.

Additional information.

Current version of TB: Version 115.9.0 Windows Version: Windows 10 Home 22H2 Email Webserver: Ionos Email Protocol: POP3

Issue Details: I use TB on my desktop to manage many different email accounts. Some from Gmail and some from Ionos. Last week, TB stopped downloading emails from one of my Ionos accounts. It still downloads from my other Ionos account and my gmail accounts. I use Aquamail on my Android device and it continues to be able to download emails for this same account. Additionally, I have a laptop with TB and it continues to download emails from this account without issue.

If you need additional information, please ask. Suggesting switching to IMAP is not useful and not a solution to my issue. I respectfully request that you Please do not go there (been down this road before). I want to fix the problem, not go around it.

I've got a Fastmail account, and have set up CardDav according to Fastmail's guide to get set up with Thunderbird.

Once my contacts synced, I was unable to see my contact lists in the Thunderbird contacts sidebar, nor can I add a list (the button is greyed out). Is this a known issue? Is it Fastmail specific, or a CardDav thing?

Running macOS 14.3, Thunderbird 115.9.0
