For the last several weeks (can't give an exact date, but it's been more than just a couple weeks, less than a couple months), both my husband and I have had issues loading videos in FF. We both have the latest version of FF. I went thru "Fix common audio and video issues" and did all those things, as well as trying to load the videos in troubleshooting mode. Nothing has helped (tho now that i cleared all the cache, i'm gonna have to log back into all those websites :( ). Nothing else is problematic. Our internet connection is fine. In fact, my husband has resorted to using MS browser to watch videos--they load fine in that browser. I have no other idea what to do. Searching your database for "youtube videos load slow" only resulted in a couple hits with no resolution. Hopefully this isn't the third. thanks

Hi!

Every 10-15 days Firefox crashes on one of the machines.

The only error I have is the "No mapping between account names and security IDs was done" in the Event Viewer at the time of the crash.

Firefox and the system fully up to date. The system exhibits no other issues.

Windows 11 Pro, no domain, crashes happen on multiple accounts on that machine.

The user is not signed in at the time of the crash. They have been using the same add-ons for years, but just to rule it out, Troubleshooting mode was attempted to no avail.

AV has been completely removed temporarily to avoid any conflicts.

Hello, I cannot log in to Twitter/x.com with the Firefox browser. There is a constant loop when registering. Firefox browser does not connect Twitter/X.com.

Thanks for your Help.

I occasionally get a Authentication Failed to Server (Outlook.com) and when it occurs it continues for 1-5 minutes then goes away again.

Is there any error logging proceedure that I can set up to see what the exact issue is?

I've tried running a parallel alternative email client (eM Client) and that doesn't seem to suffer in the same way, but I much prefer Thunderbird so would like to find out what the problem is.

YouTube has been so slow in Firefox. It just takes a ton of time for the video to actually play. It's just a spinning circle in a video. I can refresh several times and then it plays. I cleared my cache, history, data...etc everything from Firefox. That seemed to help for a bit. Then it just resulted back to being slow. It's just in Firefox. I played videos in Edge. It was fine. No issues. It's just FireFox. It started most recently too. It wasn't happening a week ago. I even tried going back to an old version of Firefox. Didn't help. Anyone know how to fix? Not using ad blockers either FYI. I just want videos to play normally and fast.

I'm grateful that I've been able to use Thunderbird for free up until now. I wouldn't mind making a small donation. However, Thunderbird's email service is currently unavailable. Received emails are not displayed in the inbox. All previous history has also been erased. First of all, I would like your cooperation in fixing the current problem and restoring the system to its previous state. I will make a donation as soon as the system is restored. If the system cannot be restored without a donation, you can make a donation first. I look forward to your reply.

"Sending of password for user joebernard@verizon.net did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later"

^^This message comes up every time I try to send an email. It can be received outside of Thunderbird and to other addresses.

I get the pop up that includes Add Security Exception

 You are about to override how Thunderbird identifies this site.

Legitimate banks, stores, and other public sites will not ask You to do this. Location:

I am in Australia and Optus is my email provider. They have checked all is working at their end and suggest I contact Thunderbird which is why I am here.

Thanking you for trying to help

My e-mails fail to be delivered to my inbox immediately. They are held up somehow and then suddenly appear days later as a batch of them as though they have been held in a storage box.

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.

Hello,

My friend recently encountered an issue where he can no longer send email messages. Suddenly, all the buttons in the "Message" tab, except for "Create," became disabled. Additionally, the "Send" related buttons in the message creation window have disappeared.

I attempted to restore these buttons using Alt -> Toolbox, as suggested by similar questions. While the buttons do reappear in the toolbox view, they vanish again once I exit that view. All outgoing servers are configured correctly, and this setup has worked for several years without any problems. It seems that something is now blocking the ability to send emails.

We also tried updating and reinstalling the Thunderbird client, but nothing has resolved the issue.

Attached, you will find images of the disabled menus and proof of the correctly configured outgoing servers. Apologies for the software being in Russian; I hope it's still clear which buttons are disabled since the interface layout is the same.

Any suggestions would be highly appreciated! Thank you.

Hello,

I have been using Thunderbird for many years without any issues. I recently bought a laptop running Windows 11. On this machine, I have two accounts that cannot send emails via SMTP. What is puzzling is that I can retrieve emails through IMAP without any problems.

For another account I had to use STARTTLS to get it working. But on my Windows 10 machine, the same account is sending emails correctly with SSL/TLS.

Thunderbird is allowed through the Windows firewall and is on the antivirus whitelist.

I recently fixed an issue (connecting to Gmail) by allowing cookies, so it might be a simple fix like that.

Could someone help me, please?

Many thanks!

Hi!

I realised that Thunderbird keeps deleting my messages in every account from the trash folder. I didn't change any of the settings and I checked them again - as you can see in the screenshot, the settings say to not delete messages in the trash. It's a catastrophe, because I've lost messages that I had to check again.

-> Is there any way to restore messages that Thunderbird deleted without my permission? -> Is there any way to make sure that Thunderbird does not delete messages any more?

Thank you!

Version: 115.3.1 on a Mac

Hello --

Not sure when this happened.

Got 2 email accounts, account X and account Y. All was working fine until today, 6/27/24. Both have different outgoing SMTP servers.

Now I am trying to send, it is asking for passwords, which I have and is 100% correct. In fact, if I put in wrong password it tells me, so I know it is communicating. When I put in the correct password, I get a timeout on BOTH SMTP servers.

I disabled Norton Firewall.

Works fine from another PC app (poppeeper) and from my android (k9 mail). Both accounts are IMAP.

Neither SSL/TLS or STARTTLS makes a difference. Nor did a re-boot.

TB 115.12.2 (64 Bit) on Windows 10

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mailroom4.hostrocket.com timed out. Try again.

Description: hostrocket Server Name: mailroom4.hostrocket.com Port: 465 User Name: ernie@e(redacted).com Authentication method: Normal password Connection Security: SSL/TLS

Anything change?
