I have been using Thunderbird for probably greater than 15 years (back when I was in college). The last couple of years I have noticed an issue of when deleting multiple emails that has gotten progressively worse, where the entire application will hang in "Not Responding". For a test, I just deleted a batch of emails from the last month (newsletters, notifications, etc), it was 113 messages, and froze the application for more than six minutes. This was on my hotmail account but the same happens for my other accounts as well (all configured as IMAP). The issue has persisted through uninstall/reinstalls and even across a replacement computer. No extensions are installed.

Any thoughts?

Kia Ora, my Gmail account has stopped downloading to Thunderbird.

I hadn't changed any settings before this happened. Have looked for solutions online, the one I saw here suggested changing the saved password in Thunderbird, which I have done, changing three gmail listings to my current gmail password.

The fix here also suggested deleting the current account, but I can't find that either.

Please advise.

Thanks Mark

Hi I keep getting this error I know for a fact my password is correct, i can sign into hotmail.com just fine.

Why do I keep getting this popup?

For about the last month or so, I frequently get an error message that my password is incorrect.

I use Thunderbird to manage emails on five separate accounts. Four are gmail accounts and I NEVER have an issue with those.

The issue only occurs with my oldest email account, which is an ".msn" account - a paid Microsoft account.

I can send and receive mail on this account without any issues when I use Outlook online through my Firefox browser, but when I try to use through Thunderbird, I get the password error message more often than I don't. In other words, sometimes the emails go through, but most of the time they do not. When I copy and paste the text of the email into the web browser version, there is never any problem and I am NEVER asked for my password.

Every now and then, when the message pops up, I attempt to re-enter my password, but most of the time it still won't send, and the error message re-appears almost immediately. I have changed the password twice, but that has no effect on the error message.

I would be very appreciative of any assistance.

Thanks in advance,

Bud

Site (https://www.pinerolo.news/

The animated images of the articles are loaded once every 3. On Chrome Android I have no problem.

I solve it manually by resizing the page, so they load.

Where could the problem be? In the animation of their site? Do you have any advice on a fix?

Hello, Thank you for helping me with my email problem today. The issue that I am having is that whenever I try to send email from 2 - of my 3 - email addresses I get the following error messages-

Message from electric@triad.rr.com email.

""electric@triad.rr.com sender rejected. The email address you are sending as must match the email address you used to auth.. Please check your SMTP settings. AUP#Out-1500. Please verify that your email address is correct in your accound settings and try again.""

message from aristot@triad.rr.com email.

""aristot@triad.rr.com sender rejected. The email address you are sending as must match the email address you used to auth.. Please check your SMTP settings. AUP#Out-1500. Please verify that your email address is correct in your accound settings and try again.""

I did read and try the various suggestions that this forum made to someonme in reference to a similar problem. The emails did appear to match in settings for SMTP and I think I temporarily turned off my virus protection software. However none of these actions have solved my problem.

If someone would please make some more recommendations I would greatly appreciate it.

Thank you,

I have been facing a very strange situation/bug (likely some addon breaking my Firefox) where I am not able to navigate/load certain sites and certain pages. Here are details:

What is working: 1. I can go to google, amazon, yahoo, and certain other websites home page, and type certain queries in the google.

What is not working: 1. I can't load Duckduckgo(dot)com, nor ddg(dot)gg 2. Though I can open Google(dot)com, but I can not search anything in Google. I can see autocompleted/suggested results in Google, but nothing happens when I click on those autocompleted/suggested queries (screenshot attached, see lower left corner, *.gstatic.com/*.google.com is loading forever). 3. I can't open any addons/extensions. For eg. Tab Session Manager, or even Bitwarden does not load when I click on it, except it shows a pixel on the right corner of addon button on Firefox Toolbar (screenshot attached for that pixel towards the right lower corner of the icon).

What I have tried already - 1. Firefox is up to date as of a few minutes ago. 2. Underlying OS is up-to-date as of a few minutes ago. 3. I have tried disabling all addons and it did fix the problem. 4. I tried changing theme (which was default black) to default, and it did not fix the problem. 5. Tried restarting PC and it did not solve the problem. 6. I tried troubleshooting mode and it DID fix the problem while I was in troubleshooting mode, at least sites were loading. But as I exited troubleshooting mode, addons started loading for a few seconds, and then once Firefox is loaded fully, I started experiencing the same problem. 7. Tried toggle HTTP3 enable/disable, which did not fix the problem. 8. Followed Firefox troubleshooting guides, it did not solve the problem (except troubleshooting mode). I tried disabling hardware acceleration and disabled any protection modes, DNS over HTTPs and other settings which might interfere in site loading - none of that worked.

My hypothesis so far - As I can access some sites on the internet, I have ruled out DNS issues and networking issues. I tried disabling all addons and it did not fix the issue (except when in troubleshooting mode) - which tells me addons are not necessarily a problem. However, I could not find what all things troubleshooting mode disables, and perhaps I should find that out. Could anyone please share any insights or your thoughts on what I might be missing? Firefox is my primary browser and a lot of my tasks are pending from over a day now. Any help is greatly appreciated! Thanks a lot!

I previously enquired and was given a ticket number 150321. I later replied to say that the problem had gone away. This proved to be very short lived. The problem is that drop-down menus are blank. Thus clicking on "New Message" button produces a minimised blank dialog. Thus I am unable to send new e-mails. Clicking on other links such as help, tools, file etc produces narrow blank dialogs. I am able to continue receiving and reading incoming e-mails. Re-starting the computer sometimes produces a short term improvement. I am using an AMD 6 core CPU 32-bit operating system, x64-based processor I am trying to use Thunderbird 115.9 on Windows 10. It used to work, but the recent, continuing malfunction might be due to an automatic update, but I was not aware of the version number until the malfunction happened.

Hello,

I'm developing a web application. Yesterday I could access it with http://localhost:8000, then, I implemented https and it worked too. Today I needed to use http again for my tests, but everytime I type http://localhost:8000, Firefox changes it to https://localhost:8000.

I already tried to clear everything in the history, even the cookies, but it didn't work.

What should I do?

Also, could you fix this bug? I've found articles from 5 years ago reporting this issue, but the bug hasn't been fixed yet

Hi I am having problems with Thunderbird, i’m not sure if it’s to do with a windows 11 update or something else. Thunderbird is not responding also at the start of the ‘not responding’ emails from one of my accounts disappeared and then gradually started to reappear but didn’t get up to date and now just not responding st all. I have tried various things to resolve this, uninstalling and reinstalling Thunderbird, doing this and opening my pc in safe mode, doing this and opening Thunderbird in safe mode. Deleting and reinstalling the latest windows 11 update, reinstalling the latest Thunderbird update. I don’t know what to try next? I read somewhere to delete your profile, after saving it, and getting a new profile but no idea how to do this. Any help appreciated.

My email for my domain (Gailfisher@Resourcesforchange.com) hosted by GoDaddy. Has been working correctly for years, but now when trying to send from TB, I get a message to enter password that does not work (it does work on my webhost's platform). Using Windows 10, TB version 115.11.0. BTW, I have another email via AOL that is working just fine on TB. I tried Safe mode -no go I tried following GoDaddy's instructions for IMAP but also did not work. FYI The GoDaddy help desk said: "Please match the server settings with the below server settings. Username Your email address Password Your email account's password Incoming servermail.[your domain name] Incoming ports IMAP - 143 POP - 110 Outgoing servermail.[your domain name] SMTP (outgoing) ports25 (587 or 80 might also work) IMAP use port 143" I tried setting up a new account in TB using email adddress and a new username, but that created the same problem. Here are the relevant screenshots. Thanks for your help!

Perhaps I am the only one experiencing this issue but it is causing such an issue for me that I am afraid I will need to abandon this browser. I never in my life thought an internet browser displaying the forums for the browser would require so many processes.

Am I the only one? I have a pretty basic experience going on here but this is causing such a struggle I might need to find a new browser. I just don't understand how this even gets to be this way.

I am very grateful for a couple of advantages this browser occasionally showcases and I really don't want to migrate to another browser across my devices. All of the options I have read in this forum are pretty much disabled by the updates to Firefox but I am willing to try just about anything within reason that won't be quickly screwed up by another update.

My apologies if I sound frustrated, but come on that's a lot of processes to show your support page and it's eating up so many resources that could be used to trouble shoot my projects in a timely manner. This impacts performance to the point that I can't watch a tutorial with nothing else going on while working with GDevelop.

Firefox uses about half a gig on my disk, that's: '~/.mozilla' and '~/.cache/mozilla' can that be reduced? Either some setting that limits disk use or even a manual deletion of ancient stuff?

A problem has arisen with firefox recently: when I tried to google something, or to open a website, I get the message: Oh no, the tab has gone down. I have reinstalled firefox but that didn't fix the problem.

I am using Thunderbird version 115.7.0(64-bit).

The Inbox is 15.5 GB in size as shown in the attached image file,Inbox Size.Jpeg.

The Inbox folder is not displayed as the attached image file,Folders.jpeg, indicates.

Please provide me with a solution to this problem.

Hello,

This is more of a puzzling question. I have been receiving multiple daily notices to Compact the Folders, to save 503MB of space. Even after doing a "Compact" I get another request or pop-up to do it again. I even went to the pull down menu and did a "Compact" from there and again less that an hour later another pop-up!! I have upgraded to the latest version 115.8.0 (64-bit) and the same thing happens.

I know I have an option to make the "Compacting" automatic but I am concerned that it will happen constantly and block me from normal usage at the worst time.

The the question is: What am I missing or what is the solution??

Thanks,

Les

Example video I have issues with: (https://www.youtube.com/watch?v=udXuzXhb9WY)

I can't watch youtube videos smoothly using the vp09 codec at 4k/1440p [Codec: vp09.00.51.08.01.01.01.01.00 (313) / opus (251)]. Constant buffering, lag, pausing of the video or just not playing at all keeps occurring with the video I put above for example, and other videos using the same codec.

My internet connection is very quick in fact, with getting ~90mbps upload/download. My computer specs are good, having an i7 12700kf and an rtx 3060 with 64gb of ram. All my drivers are on the latest version. The video I linked above plays for about 10 sec before not loading more of the video and just infinitely loading (The main issue that is causing this to happen is that when I open stats for nerds, the buffer health isn't being updated).

I tried various solutions online that I found on forums, such as forcing av1 encoding, which fixes the issue, however on that specific video I linked, keeps the quality at 1080p, which probably is a issue on youtubes part and the file format of the video. I tried many other fixes.

On microsoft edge, the video plays fine with no playback stutters or anything. I don't have any 3rd party extensions installed that may affect the video playback. I did a lot of things to eliminate as many variables as possible, but the issue persists. I did a full reinstall of the browser, reseting cookies and temp data and also trying the nightly version of firefox, but non of those fixes worked. Basically everything I thought of I did.

Like I mentioned before, this issue is NOT only for the youtube video I linked, but its for all videos using just the vp09 codec for the 4k/1080p quality. The only fix I did find for that video is actually while writing this, I left the tab open for the youtube video for a while then played it and it played smoothly with no interruptions and the buffer health was constantly being updated, but after refreshing the page, it was the same.

From what I can remember this issue hasn't been happening for the lifespan of my pc (less than 6 months), and I cannot remember when the issue started happening. It seems to be pretty recent (maybe 2-3 months if I were to guess). At first I started tolerating it and thought it was a small bug since it only happened on videos I played at 4k using the vp09 encoder, but now its really frustrating and makes it possible to watch most 4K content. Some videos I notice when it starts buffering, it resorts to an alternate av1 codec for 4k video, but its only for certain videos. Unfortunately I cannot back track and see what started this issue.

Here is some additional info:

   Windows 11
   NVIDIA Game ready driver version (555.85)
   No abnormal resource usage (Gpu, Cpu ram etc.)

There's not really much skirting around it. Yesterday, I came across this sudden error with my Firefox browser on PC (see annexed image), which basically rendered me unable to open it for some reason. It did get fixed that same day somehow, though for a short while, as I was faced with the same error message again today and once again haven't been able to open my browser, much to my frustration.

I tried searching about it on the internet, but didn't find anything of help – most videos about it refer to a mistake on the Windows OS with the same code (0xc000185); asking around to people I knew didn't do much, either.

Today I tried a bunch of stuff to see if it resolved my problem in any way, such as: 1. Restarting my laptop (didn't work); 2. Installing both suggested and optional updates available to my Windows version (put me at ease a little, but still didn't work); 3. Searching for malware (antivirus didn't find anything, so I'm thankful this one didn't work); 4. Verifying system files with 'sfc /scannow' (all was good, so it didn't work);

I was also going to try doing a 'chkdsk /f /r', but I didn't have time to, as I had to leave for something. There are also other things such as creating another profile, which I'm considering; updating Firefox, which I can't do because I can't open the browser to check if there are any updates; and reinstalling Firefox, which I'm slightly afraid to do and will leave as a last resort because I don't want to risk accidentally doing it wrong and losing all my history, bookmarks, etc.

Any help would be incredibly welcomed. Thanks in advance.

P.S.: The text on the error message reads (translated from PT-BR): "The app couldn't be started correctly (0xc0000185). Press OK to close the app." Sorry if the photo isn't very good.
