I'm a writer. In keeping with the Law of Primacy, my first work is usually my best work (after a few tweaks). I recently had to write an email response to someone for the Darling Bride and me.

I waxed poetic and wrote an incredibly diplomatic response to a most unpleasant situation. After completing the entire message down to our signatures, I selected "File" and "Save" to make sure it was all saved in the Drafts folder. That way, I could open it on another device and read the draft to her.

Imagine my shock when I opened it, only to find that the draft stopped in the middle of a word - while I was correcting a typo - and didn't save anything after that! Frantic, I went back to the computer I used to write it, hoping the entire email was at least saved locally. Nope! The draft stopped in the middle of the message, even though I had saved the entire thing.

Perhaps this isn't high priority for a lot of users... but for those few of us, it's a critical, fatal flaw that has to be resolved. I can't even imagine that I did anything wrong: I saved the message before exiting; and opened to find half of it missing. I love the idea of Thunderbird and its privacy features, compared with the data-mining big names. But I can't afford to lose data! This was a personal response, thankfully, and not related to my work as a writer and author. However, I have to trust my email client with the data I save to it. Any hints to prevent this are greatly appreciated.

When I restart Mozilla Thunderbird, my S/MIME certificate preferences under Account Settings seem to break.

When I initially select a certificate, both the common name/certificate name and the certificate fingerprint appear in the interface (see Working Settings.png). However, after restarting Thunderbird, only the common name/certificate name appears in the interface, and I cannot use S/MIME to sign messages (see Broken Settings.png). When I attempt to do so, I receive the following error message:

Send Message Error Sending of the message failed. You specified that this message should be digitally signed, but the application either failed to find the signing certificate specified in your Mail & Newsgroup Account Settings, or the certificate has expired.

To be clear, Thunderbird has no problem finding and using the certificate right after I set it—the problem only appears when I restart Thunderbird and the appearance of the certificate in the settings changes. The certificate does not expire until April 2025, so this is not the issue. The issue also occurs with another account using a different certificate that is also unexpired.

I am using Thunderbird 115.12.2 (64-bit ESR) on MacOS with Apple Silicon.

https://www.yourclassical.org/episode/2024/07/07/composers-datebook-john-williams. I get daily emails like this from this website that allows me to click a button and listen to a two-minute feature. Of late, the screen is wobbly and does not allow me to click the button. The website works fine on Chrome and Edge.

Hi I have been having issues with my Thunderbird emails which would not send or be received. Now I can send but not receive.

Whenever I use it or open it I get one consistent error message as follows:

"Could not connect to mail server mail.transitioncoachingbedford.co.uk, the connection was refused"

And on sending emails I get a pop up error that says:

"your message was sent but a copy was not placed in your sent folder due to network or file access errors".

I've turned the firewall off, I've uninstalled Thunderbird and re-installed but can't fix. I've read through suggestions for fixes on other issues that sound the same but am not at all computer minded and don't understand most of the suggestions.

Can anyone please help as this is my business email. I've got access to the emails on something called RoundCube but not sure what to do.

This isn't strictly related to Hulu but using it as an example: Hulu has some bug right now where it will occasionally suddenly use a lot of CPU power and completely lock up Firefox, and to some degree my whole system. If I manage to "close" the tab, it *appears* to close, but it's very clear that whatever Hulu is doing is still going on in the background. This time I was at least able to open the task manager and kill Firefox – which immediately alleviated the problem, and upon reopening Firefox, the Hulu tab was still there (indicating it never closed).

I don't know if this is possible, especially given I don't know what's causing the bug with Hulu, but it would be nice if Firefox was better able to handle a tab getting out of control like that.

Mac 14.5, Firefox 127.0.2 I have refreshed Firefox, disabled extensions, restarted my macbook pro, all of these things multiple times. What's the problem/fix. All the solutions I see are from a year ago. How about some current help/fixes?

The nine dots that appears on most Google pages to allow for choosing an app does nothing. It does work with the Samsung browser. This is reason that I have not changed to Firefox many years ago. I was hoping that it would work by now. Is there a change in the settings for Firefox that would allow this to work? If there isn't, I guess that I am stuck using the Samsung browser, as I don't like the Chrome browser.

I've not been able to download anything on Firefox for about 3-4 weeks now. Every time I try to it immediately fails with no explanation given. The only type of download that works is "Save Image As..." Even trying to download a picture with a download button instead of right clicking nets an immediate fail. I feel like I've done everything to try and troubleshoot it myself, but nothing seems to be working.

I've restarted my computer, ran Firefox in troubleshoot mode, refreshed and reinstalled it, checked for viruses and malware, tried both nightly and ESR versions, tried running them as admin, logged out of my Firefox profile, cleared my cookies and cache, changed and reset the download folder, ran a repair for Visual C++, and reset my windows security settings. I'm honestly surprised nothing has worked.

The only thing that I know I haven't tried yet it refreshing my entire computer, but that's my very far last resort because I'm able to download files just fine on Microsoft Edge. Only the Firefox applications have given me any problems, so if I were to refresh my computer and have the problem still not be solved somehow I'd be deleting everything to get nowhere.

If anyone has any other ideas to try that be very much appreciated.

Hello,

I deployed central management of firefox yesterday and I am suffering firefox hangs on startup (prior to opening any window) after configuration change from pref to localPref. When I kill firefox and run again it usually start normally. Usually one kill is sufficient, but I observed also two subsequent kills are necessary.

I created these files:

/usr/lib64/firefox/defaults/pref/autoconfig.js:

pref("general.config.filename", "firefox.cfg"); pref("general.config.obscure_value", 0);

/usr/lib64/firefox/firefox.cfg:

// This comment is mandatory lockPref("autoadmin.global_config_url","http://www/firefox/firefox.cfg"); lockPref("autoadmin.append_emailaddr",false);

and in the firefox.cfg on a website I have for example: lockPref("network.proxy.type", 4);

when I change the lockPref to pref in this file, everything works normally, but when I change it back to lockPref I get a firefox hang on startup. What am I doing wrong?

Thanks

Whenever I have Firefox open with certain games, the browser randomly freezes and ultimately crashes. But especially when I have videos running. The game itself does not crash and runs completely fine with no issues.

I have no idea what causes it, and I used to not have this issue at all before. However, I believe it was after I upgraded my computer, which should have no issues with the specs I have.

These are my 10 most recent crash reports: bp-c0eafb4b-6fce-47fa-9e8d-3f9e30240707 bp-dc43a38b-a3df-4231-9e02-ff55c0240707 bp-30bc891a-062d-4f9d-805d-539a20240707 bp-8dda914d-f2f8-4534-83d6-2ac690240707 bp-1858f133-89be-41e0-85e0-501a70240707 bp-e785dd9b-328b-4aec-bff0-002fe0240707 bp-3e7288ac-6d1e-4567-9e95-1a4830240707 bp-2777d574-893b-4e10-a69e-245f90240707 bp-62934e0d-9568-4deb-9354-e7e910240707 bp-2ab1d2bb-d244-4118-a7e1-9d32e0240707

For some months now I have been finding that, when I try to log on to the BBC website or the Youtube website using my default browser Firefox I get a timed out message. However, both websites usually open when I try for the second time. This never happened before. For both sites I log on from Windows 10 desktop icons. This defect is now annoying me so much I am inclined to switch to Chrome or Microsoft Edge as default browsers where the problems do not occur. I have tried a number of suggested solutions shown on line but nothing has worked to date. Before I switch default browser I will try further suggested solutions if anyone has any.

When I put a video or an image gallery to full screen, the navigation buttons, clock, and status bar don't hide.

They often appear as though they're going to hide, for a split second, but frustratingly bounce right back into view.

On rare occasions, it seems to be random chance, the status bar, clock, and navigation buttons do hide, but I don't know how to get them to hide every time.

I've already tried disabling picture in picture for the app but that has not helped.

What are the reasons the buttons and clock would not hide in full screen? How would we go about fixing things?

Firefox keeps going off for from 5 seconds to about 20 seconds. It happens several times a minute. The screen goes blank and I can’t click on anything. Really aggravating. I would appreciate any help. Thanks

Hello, Since yesterday, the Firefox web browser crashes systematically. This has happened well over a dozen times. I've tried multiple step-by-step solutions: deactivating extensions, troubleshooting mode, repairing firefox, uninstalling and installing Firefox, trying several versions of Firefox (Quantum, ESR, Nightly), downgrading to an earlier version, uninstalling and completely cleaning Mozilla folders on AppData, deactivating graphics/hardware acceleration...

At one point, Firefox was crashing after ten seconds of watching a video on Youtube or another platform. After reinstallation, video playback no longer causes the browser to crash, but closing a tab does.

I am currently using Mozilla ESR 115.12.0. After reinstalling, I lost all the reports I sent. Nevertheless, I was able to reproduce the crash to give you the ID: [https://crash-stats.mozilla.org/repor.../a2d0f5de-d03f-450b-88f8-a8fdc0240705] Another crash report : [https://crash-stats.mozilla.org/repor.../71c602f6-c682-4158-9880-24d6a0240705]

According to the crash table, the reason for the crash is as follows: EXCEPTION_STACK_BUFFER_OVERRUN / FAST_FAIL_GUARD_ICALL_CHECK_FAILURE This reason appears on all crashes.

Thank you.

Hello, In my work email account (Zimbra instance), very regularly new emails keep reappearing as unread even after they are marked as read. If I restart Thunderbird, or if I go offline then online again the problem is solved; however, I would like a more definitive solution.

When the problem occurs, in the console I can see "The current operation on 'Inbox' did not succeed. The mail server for account X responded: mailbox selected READ-ONLY.". I tried solution suggest at https://support.mozilla.org/en-US/questions/1276757, i.e., setting `mail.server.default.send_client_info` to `false`, but it did not work. Any other suggestion?

Hi,

When I seek in videos, for example on youtube, it almost always hangs the entire machine. The same issue happens randomly as videos run, eg after about 5-7 minutes.

I'm struggling to get more information on what is happening (eg logs) because the whole system hangs.

Here are some things I have discovered:

1. I can reproduce in a fresh profile 2. I can reproduce with the flatpak version 3. I can't reproduce in the Brave browser 4. I can't reproduce the problem on Windows, only on this Linux machine

I'm running on Linux (debian bookworm). I'm using wayland. I have an intel i915 GPU (Alder Lake).

The problem started recently (last few days), but I'm not able to nail down exactly what changed.

What I really want is any way to get more information about what is happening - logs or debug output or whatever. Then I can work out if the bug is in Firefox, or something else on my system (eg intel graphics drivers)

Thanks, Cal

I have four browsers on my Linux box: Chrome, Chromium, Thorium, and Firefox.

Firefox is painfully slow using Google Earth, all the others are fast with Google Earth.

This is fairly recent behavior (last month or so).

As far as I can tell, FF is configured to allow Web Assembly (WASM) to be used for rendering images, etc. Since Google Earth is written in WASM, I don't have a clue why it is so horribly slow.

scrolling/sliding the image around on the screen is slow and jumpy. Displaying images attached to a waypoint is extremely slow: It takes 5-10 seconds to switch from one image to the next.

Any suggestions? Thanks in advance!

Fred
