Good morning. I need help with sending emails in Thunderbird. The problem has existed for a couple of days now and is confusing as some emails are sent and others fail. I am receiving mail OK. Details of my setup are :- I am using a HP All-in-one desktop running Windows 11 with Norton 360. My Thunderbird account settings: Server type: IMAP mail server User name: ****@gmail.com Server name: imap.gmail.com Port: 993 Connection Security: SSL/TLS Authentication: OAuth2 Outgoing Server (SMTP): Google Mail – smtp.gmail.com (Default) User name: ****@gmail.com Port: 465 Connection Security: SSL/TLS Authentication: OAuth2

The problem: I only recently set up Thunderbird and at first it seemed to working OK. However, now when I try to send a message, after some time, I the following error message :-

"Send Error Message Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. Try again."

What is particularly confusing is that some messages are being sent. I have tried several fixes that I found from the Mozilla, Google and Norton web sites but none of the fixes resolved the issue. Any assistance would be very much appreciated.

Regards Mike

PS: I have 2 email accounts set up in Thunderbird. I just tried sending a test message from the Gmail account to the Bigpond account. From the Gmail account it appears to have been sent but in the Bigpond account an error message appeared as follows :-

"Could not connect to the mail server smtp.telstra.com; the connection was refused."

I don't know if this is a related issue or I have another one to resolve.

I've read a few historic suggestions about how to resolve this, but I haven't been comfortable with what solutions were suggested as they didn't seem to comprehensively answer the questions, I'm afraid.

Until this morning's attempts to resolve the "running out of disk space" warnings, I had two mail accounts on Thunderbird - my old Hotmail account and my new personal domain based account. Both accounts had old emails (3/4 years' worth) filed locally on my PC pending my satisfaction that the new mail account was working satisfactorily. To try and resolve the storage issue, I deleted all the locally stored emails from my Hotmail account from within Thunderbird, then deleted the Hotmail account, and restarted both my PC and Thunderbird.

The expected reduction on space occupied by the .thunderbird folder didn't materialise - at all.

How can I get back the space so I can continue working, please?

My phone has been deleting emails from my mozilla account and removing them from my laptop. Although I can still delete from my phone they don't delete from my laptop. This system has been working for years and I've only just noticed the problem. I normally use my phone for this so I have about 3 months worth of emails still on the laptop.

Since the latest update, when I right-click on a bookmark or an item in the history list (from the menu or the bookmarks toolbar), I still get the menu that has items like "Open in new tab" or "Edit Bookmark".

However, the focus for the mouse stays on the previous menu, so that I can't click on anything in the "right-click menu", instead it is interpreted as a click in some random item in the previous menu.

Going into troubleshoot mode didn't help, so I don't think it's my configuration causing this.

Hello, I have a problem: After an automatic update of the language packs, parts of the Firefox menu (version 126.0) are displayed in EN. Parts in DE. Seems to be related to the update... how can I change this again? I have already changed the language settings. Didn't help...it appeared after an automatic update on May 28. Thanks for an idea :)

I installed Thunderbird and eventually got it working. I download with IMAP and upload with SMTP. TB did a great job downloading gobs of email from Gmail and converting the labels into folders. In a couple cases, it created folders, but none of the emails with that label were downloaded into the folder. FOr example, there is a folder 'PE' and a subfolder " CD Ads'. Emails are present in both. However, in TB, 'PE' is lighter grey and italicized and empty.

The folder structure is not an exact match to the label structure. For example, in the labels, I have an 'Employment' label with 5 employers underneath it. None of the employers made it into TB.

I have a few other oddities too, but lets start with these. I did end up using a normal password to access the account, as 0Auth2 would not cooperate.

Thanks for you insites!

Hello, I recently installed Ubuntu 24.04 with the version of Thunderbird (115.10.1) supplied with the distribution. I can no longer display mail saved as .eml in a remote folder (sftp). Thunderbird opens, but the mail window is empty. If I ask for the source code, this message appears:

Unable to read file at address view-source:file:///run/user/1000/kio-fuse-ouSeRu/sftp/myuser@myserver/mymessage.eml?type=application/x-message-display.

If I open from CLI I get this message :

JavaScript error: chrome://messenger/content/aboutMessage.js, line 218: NS_ERROR_FILE_ACCESS_DENIED: Component returned failure code: 0x80520015 (NS_ERROR_FILE_ACCESS_DENIED) [nsIMsgDBHdr.mime2DecodedSubject]

If I open the save file with a file editor I'm able to see the source code.

Could you please help me? Thanks

Hi all,

I feel like this is a problem that must have been experienced and solved a thousand times... however I've tried all the suggested fixes I can find and the problem still persists.

When I load Firefox the pages take ages to load. It doesn't matter what the page is, it takes ages, except that about: pages load fine, no problem. When I say pages take ages to load, I mean that everything about the page takes ages, not only the next, not on the images and other content etc, everything. This only started happening today and I only created a new profile a month or so ago. I don't have many tabs open (maybe 20) of which 9 are pinned. I do have lots of extensions installed.

I've tried troubleshooting/safe mode, that makes no difference.

Private browsing and loading another profile are fine, they don't have this problem.

I've cleared all cache and data, cookies, etc, including startup cache.

I've deleted the content-prefs file, and removed places files.

I've tried disabling and enabling hardware acceleration.

I've tried disabling TRR.

Probably some other things too, but so far nothing has worked.

Suggestions please! :)

I had an email account from my university that used gmail in the past but just recently disabled the email and migrated away from it.

However, when I removed that email account from thunderbird and restart the app, the oauth dialogue to authenticate the disabled account each time. It would also keep opening that dialogue every 30 minutes. Any help is appreciated.

I am using a Mac with Big Sur (macOS Monterey, Version 12.7.5), and my email is POP, using Thunderbird Version 115.11.0.The message count of my inbox is wrong. It is two (2) more than it actually is. Right now there are ten (10) messages in my inbox BUT the message count of my inbox says twelve (12). Please correct.

TB won't set up on Yahoo mail. Spent about 3 hours on the phone with one and sometimes two Yahoo techs and giving them total access to my computer so they could set up TB but could not get it working. It was eventually suggested I contact you folks, so here I am. When sending an email, it just keeps running like it's sending but doesn't stop. Eventually displays the following:

Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp.mail.yahoo.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

The techs and I went around an endless loop of re-entering PW and checking authentication settings. Any suggestions?

Support,

The USPS website does not work properly with Firefox!! The Home page loads okay but there are multiple other issues with links not working. For instance all of the links under Quick Tools do not work except this one: https://www.usps.com/manage/po-boxes.htm. Other things don't work either.

Everything works fine that I tried with Google Chrome though! Please address soon.

Thanks

I have been using Firefox for many years and never had issues. Two days ago, I turned on my HP with Windows 10 and I got a pop up message something about Error Platform 126.0 XUL Runner is not compatible. I could not access Firefox, Google, or the internet. I uninstalled Firefox and reinstalled, but after that, everything runs very slow. Each time I go into a website, it can take up to over a minute to pull up! I cannot even delete email from my Gmail! It's piling up. Downloading can take over an hour! I checked all the trouble shooting forums in Mozilla and tried just about everything. I went back into "About:profile"s and created a new profile. It it did not make any difference. I also did a Firefox refresh. Did not help any. I went back into the profile I had before the XUL error because my bookmarks were there. Still slow. I cleaned out the cache, in both Firefox and my Windows 10. made no difference. I only have three extensions in Firefox. I don't know what else I can do to fix this. Also, my drivers and other software are automatically updated by Windows. My HP is only 2 years old as well. Everything was fine in Firefox until that XUL error message popped up and I had to uninstall and reinstall Firefox. That is when everything became agonizingly slow!

Update: My computer is barely usable anymore because of the Firefox issue. Having to wait for a minute or more for everything I do on the internet? I know it cannot be my computer itself because it is not even two years old yet. I may have to dump Firefox if I cannot get this fixed. I have Norton 360 and it is not malware or a virus. Firefox messed something up.

Every time I open Firefox, it crashes immediately and does not trigger the crash report window. Even though I have checked and enabled the option to send crash reports in the settings, it doesn't work. When I look for crash report logs, it shows that I have not sent any crash reports.I've tried many methods to view the crash report, but it just shows that there are none. I only found this information related to crash reports in the installation files.(you can see it in the picture)，hope someone can answer this question, thank you very much.😭

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.

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

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.
