Since starting my Win 10 Pro computer today, Thunderbird 115.4.2 (64-bit) has been "dead in the water". When it's launched, it posts the customary "Downloading Message 1 of [N]" status report, but then hangs right there, takes 3 or 4 minutes even to (re-)populate the tabs and panes that had been open, doesn't get past the alleged first new msg even in 15 or 20 minutes. When it does populate the Inbox pane, it shows no messages newer than last night just before shutdown. Very sluggish response to cursor, too: for ex. 30 seconds from clicking on a msg title in the Inbox pane to displaying that msg, even longer to bring up Help/About (with "Not Responding" shown in its title bar.)

  I get my mail through gmail's IMAP server but prefer to use Tbird's interface . Thinking there might be something evil about the first msg that was waiting to be downloaded, I used gmail's web interface to review everything new since last night, deleted several msgs that had attachments, then started Tbird again.  No change.  Can't even get Tbird into the "Work offline" state because it attempts download-of-new-msgs immediately after being started.
  The only consistently effective way I have found to STOP the hung Tbird is through (Classic) Task Manager's "Processes" list, which usually shows five or six "thunderbird.exe" instances.  After selecting whichever has the largest memory allocation I click on "End Process."
  This all "feels like" a bollixed internal state.  Does Tbird store internal-state information in its own file, or is it buried in the Registry?   If I attempt restoration from a backup, which files are needed; or is that unwise?
 I see there is a mid-April update available to 115.10; would installing it reset current messed-up internal state, or will that already messy situation prevent the update?   Is there any risk of losing my Inbox, Sent, etc contents?

Thanks!!!

On my Android phone, the "close private tabs" notification keeps reappearing no matter how many times I tap it or swipe it away. Only way to get rid of it is by force stopping Firefox. Weird thing is that this issue doesn't repro 100% of the time either.

This is happening on Firefox 126.0, on my S23 Ultra running Android 14/One UI 6.1

Hello there, for past few days I'm having issues mainly on Twitch.tv - the streams do work fine, but whole website is displayed as text - Avatars, emotes, badges are displaying as text, or don't display at all, I'm attaching screenshots as examples. What I've tried - restarting PC, router, full re-install of Firefox, disabling all add-ons and uinstalling them (7tv and FFZ), private mode, troubleshooting mode, creating a new profile in Firefox, checked firewall settings, checked AV settings and did multiple scans - nothing was found, tried changing Firefox security Settings, also cleared cache and cookies.

I think that's everything - I was doing everything that was in the article: https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems

Regarding other websites - this is completely random, mail works, some websites also do, but on some it gets stuck, like for example when I have to do a 2FA somewhere and get a pop-up window to click "login" or type a code, it just gets stuck and nothing shows up.

Not sure if this helps, but exactly same issues appear on different browsers - Chrome, Edge, but only on PC. I tried Firefox on mobile and it worked just fine.

If I can provide more details please let me know, I did attach the "Troubleshooting Information" so hopefully this also helps.

Thank you in advance!

I'm unable to open pdf in mozila as it is showing access denied in acrobatservices.adobe.com in the all other browser its opeing perfectly please fix this issue vfast

Firefox spawn too many child processess, with cause the browser to freeze.

Proposed solution:

Reduce to absolute minimum the spawn child processess. The value should be set according to the device performance and additionally show allow the user to set manually the limits.

Example: 1 (maximal 3) child process per tab/window

This is basically the same issue as someone posted in https://support.mozilla.org/en-US/questions/1431097 I posted it there as the latest reply, but the thread is idle. So- I am receiving regular emails with jpg attachments from IP security camera, sometimes jpg is displayed, sometimes not, at the same time using mobile phone email app or on my win10 pc other email app it shows just fine. Also strange that when I try to open the attachment with faststone image viewer- nothing happens at all, if I try to save the attachment, it is saved, but the size is 0 bytes, though in a message view it shows as 241 KB. I have tried solution from https://support.mozilla.org/en-US/questions/1404538 and no difference, seems like a bug. Today I noticed that not only jpg, but also pdf files sometimes have the same issue. Email provider is outlook.com

I was using thunderbird. I accidentally hit the sort by star right above the email list. The application crashed closed. When I reopen it, it immediately crash closes. I can't even get an pointer arrow for long enough to exit myself.

On window 10. Thunderbird was up to date.

Tried - restarting computer. Signing out of TB in the crash report box. Can't get into safe mode.

Hello, I have a weird bug with the firefox browser causing weird graphical glitches only on the main screen when a HDMI cable is plugged in on the duplicate mode. I have found that is is only on firefox and not my desktop or any other programs. Firefox is up to date and the issue is fixed when the HDMI set to extend

I hope you find out why this is happening and fix it swiftly Thank you -Dominic

For a couple of months now, my favorite browser, Firefox, has been locking up on me. It started this year right after an update. It suddenly locks up! Completely! Sometimes I cannot get it to close. I have had to shut down my pc to get rid of a locked up Firefox browser. These days I only need to right click the Firefox tab on the task bar and click "Close Window". That has been a big help.

So, I give up on Firefox and made Chrome the default browser. Then behind the scenes, someone installs a patch to the main server and fixes the problem.

I check it often and when I see that you fixed it, I set it back to default browser for about 2 or 3 weeks and then Firefox locks up again. I shut it down and switch to the Chrome browser again.

Back and forth I go. It locks up. I switch to Chrome. You finally fix it yet again. I try it after a few days and discover that you fixed it and make it default browser again.

And here I am again! I cleared the lock up by right clicking on the taskbar Firefox tab. Now I get a dialog box that has an option to shut down Firefox. Then I see a time bar move across the dialog box and close. Nice touch!

Now I switched to the Chrome Browser again and I am waiting for you to fix your Firefox browser for the 5th or 6th time this year.

Let me give you some advice. Burn it to the ground and start over. What you are doing does not help!

I've been reorganizing my folders, and while working on this, I will occasionally find that I can no longer create a new folder or rename an existing one, or, somewhat worse, when I rename a folder, it will disappear, along with the messages that were in it. The messages that were in the missing folder don't show up in a search, and aren't in trash.

If I close Tbird and quickfilters, and sometimes also restart the computer, the functions again work as they should (but the missing folders do not reappear). Rebuilding the parent folder doesn't recover the missing subfolder. The problem can happen when Tbird is the only open application.

Any idea what can cause this? Or where the missing emails might be?

Thanks Kent

I belong to almost a dozen regional 'yard sale' groups, and suddenly can no longer post 'for sale' in ANY of them including Marketplace. Yet in the same groups I can post and reply to messages

My wife is an ardent and long-time Thunderbird user. She has tens of thousands of old emails organized into dozens of folders. Recently she noted that many folders contained scrambled emails. For example, an email titled "The race to re-design sugar" from Sept. 2020 now contained what looked like content from an email from Office Depot. See below for a short piece of the body of the email. Anyway, I ran Thunderbird's "repair folder" function and not only did it not unscramble the emails, it also seems to have deleted any emails prior to 6 months ago. Fortunately I've got her T-Bird profile file backed up daily, so was able to restore the original (but scrambled) emails. Any thoughts? I use outlook, but I've got pretty good PC skills if you need to take me into the weeds. Thanks!

Example of one of the scrambled emails: 'From - Sun Feb 4 12:28:28 2024 X-Account-Key: account5 X-UIDL: AEZHkUhl+QCXZb/zNgpcWOY28vQ X-Mozilla-Status: 0009 X-Mozilla-Status2: 00000000 X-Mozilla-Keys: Received: from 127.0.0.1 by atlas-sbc-production.v2-mail-prod1-bf1.omega.yahoo.com pod-id atlas--sbc-production-bf1-7448fd4479-zt82t.bf1.yahoo.com with HTTP; Sun, 4 Feb 2024 20:27:34 +0000 Return-Path: <error@em.officedepot.com> X-Originating-Ip: [20.57.66.208] Received-SPF: pass (domain of em.officedepot.com designates 20.57.66.208 as permitted sender) Authentication-Results: atlas-sbc-production.v2-mail-prod1-bf1.omega.yahoo.com; dkim=pass header.i=@em.officedepot.com header.s=officedepot; spf=pass smtp.mailfrom=em.officedepot.com; dmarc=pass(p=NONE) header.from=em.officedepot.com; X-Apparently-To: xxxx.xxxx@att.net; Sun, 4 Feb 2024 20:27:34 +0000 X-YMailISG: T.w7qP0WLDtIndBfVsii11yVLG9YUwuh8bXrpNWGHf2Ezt9n W35tfL8ReGJq0phUGg1KeSNel41YbOoogg21rDC6q0i7xvo0jIbdikP0kWCS '

Received an encrypted message but the content appears to be only my public key. Message not visible. Copy of same message was displayed in the clear in gmail on a computer that not set up to encrypt. Any suggestions gratefully received.

Hi, for some time now (around a month), after a couple of days using Thunderbird, I can not load new messages, can not send new messages, and it basically is nonfunctional. The blue bar down right shows an active process that never ends (for example, "sending message"). All menus and software as a whole are still operating, and there is no crash on hang, but every attempt to load my emails or send data ends with endless waiting (no errors whatsoever). When I try to exit the application, it closes down, but a process is listed in Task Manager. When I kill the process manually and try to start the software again, nothing starts (a new process appears in the task manager), but the software never opens a window or something. Only a full computer restart helps, and everything works again for 1-2 days. I have disabled all extensions and tried even troubleshoot mode. No crash reports...

Hello

I have a bizarre issue with attachments.

I open all attachments in their respective programs rather than preview within Thunderbird itself (I have also tried opening in preview but I get exactly the same problem).

When I receive an email with attachments, mainly Word, Excel or PDF docs, I click to open the attachment but nothing happens. If I save the attachments to my computer and try to open it says the attachment is empty or corrupt.

But, if I click to forward the email, I can then open the attachments as normal by clicking on them in the draft email and also then save them to the computer and they open as normal.

I am running the latest version - 115.10.1 (64-bit) and I have noticed this issue for about the last week or so. Otherwise everything seems to work as normal.

Any ideas on what is going on or ways to change this.

Thanks in advance

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.
