As stated in the question, messages older than 1000 days are not deleted (this is a POP server). This is on my Desktop which is my primary PC. I also have a laptop using Thunderbird with "Leave messages on server" but with neither option (Number of days or Until I delete them) checked. The purpose of the laptop settings is that since it is not my primary PC I don't want it to delete anything from the server.

I did quite a few searches and the closest thing I found was another user who had migrated to Thunderbird after using another mail client for years, and it sounded like after they installed Thunderbird, they imported their old emails from the old client and then began using Thunderbird. The explanation they got was that any emails that had not been downloaded from the server by Thunderbird would not have a download date in Thunderbird and would therefore not be subject to the "older than xxx days" setting. That scenario doesn't apply to me because I have been using Thunderbird exclusively for at least 5 years, so all emails on the server that are less than ~1825 days (5 x 365) were downloaded by Thunderbird. All emails older than 5 years have long since been deleted from the server manually.

Either I am misunderstanding the "For at most xxx days" setting or something is not working properly.

Normally when you starting to write a new email, Thunderbird will set the 'from' address to the address of the account whose mailbox you're current browsing.

However, I have a saved search that entirely contains email from my secondary (work) account, but if I start a new email while browsing it, it picks my default (home) email address. This has caused me to accidentally send emails from the wrong address more than once!

Is there any way to change it so that it'll set the 'from' field of new emails to my work email when browsing that specific saved search?

I am using Firefox version 125.0.3(64-bit). I am not able to access my saved passwords. It is asking me to log in when I am already logged in to my Firefox account. When using Firefox in Troubleshoot Mode I can access my saved passwords. How do I solve this problem? Moreover I am unable to add a Primary Password to protect my saved passwords. I have never tried to add a primary password before this problem.

Bug forever (years, versions, reinstallations).

Failure by filters whose action is to DELETE. As stated in subject. Uncomplicated.

Other filters work (they distribute msgs into specified folders).

Comcast/Xfinity is binning email sent from Thunderbird to yahoo, gmail or hotmail

This problem started on April 24.

I have compared the Mozilla info at the front of emails sent to my wife before and after April 24. The only differences other than Subject and content are:

    From - Mon, 22 Apr 2024 16:34:28 GMT
    From - Sat, 27 Apr 2024 08:10:47 GMT

- The Message-IDs are identified as @acm.org - My sending address with Thunderbird is @acm.org - My ISP for Thunderbird is @comcast.net - If I send from xfinity.com which is comcast, the emails succeed - If I send from Thunderbird, the emails fail as follows

I am running the latest updates to Windows 10 Pro x64. One of my monthly bills is paid at

1) https://e.synchronyfinancial.com/

which, in Brave, redirects to

2) https://lowes.syf.com/accounts/login

Inputting either link in Brave gets me to the finish line but the first link above fails in Firefox with the "Secure Connection Failed" message and dumps me at https://www.synchrony.com/accounts/. The second link does the same.

Is there any way to troubleshoot the problem?

I HAVE tried shutting-down Malwarebytes but the result was the same.

This is the only site on which I have encountered this issue. All that I can determine at the moment is that that certificate is from DigiCert and the expiration date is in 2025, i.e., this is not a Symantec cert.

I don't use Google Chrome browser nor do I use MS Edge. After using the Mosaic browser, I switched to Netscape Navigator, then to Mozilla, and, finally to Firefox. I am not looking forward to migrating to another browser. ;-)

Been using Thunderbird for 5 or 6 years now and am a big fan. However, in the last few versions, the tool seems to be more and more resistant to actually checking for mail when told to do so.

It frequently does not check at startup ("Check for new messages at startup" is checked for all accounts), and also does not check when "Get all new messages" is selected.

I have tested this with known mail waiting to be retrieved and Thunderbird does not do it when directed. It did eventually do it, and downloaded the mail, but I am not sure why the reluctance to check on demand by the user.

It is possible it may just not be REPORTING that it is checking, but failing to get mail I know was there kind of makes that less likely.

The earlier versions, from 5 years ago, worked very well in this regard... always checked on startup and when told to, always reported the activity in real time as the check proceeded. The newer versions are not good at this. Or it is user error, which is definitely possible, but I'm not sure what I might be doing wrong.

Currently using Thunderbird V115.10.1 64 bit, running on Linux Mint MATE. This is the newest version available as of Apr 29, 2024, and the problem seems to be worse in this one than in the previous version. Not positive on that, but I did have a dickens of a time getting mail downloaded that I knew was there.

Any input or ideas will be most appreciated, thank you in advance.

Can't print emails or any saved Thunderbird files. I click on FILE>PRINT and get the print preview, butwhen I click on "PRINT" I get a "printer offline message". I can print from Microsoft Word or PDF files and any other program. It appears that everything worked well until the latest Windows update was installed.

I am using an HP printer and print via HP's Smart Print software which I believe is the default. I'm not sure if this is a Thunderbird issue or another screw up by Microsoft.

Thanks for your assistance.

Firefox just will not print anything at all. I have tried all the suggested fixes; everything else on my computer prints fine to either directly connected printers or to network printers. The 3 other computers on my home network all print to all printers from Firefox. I have deleted Firefox and reinstalled I have deleted all printers and reinstalled When I do try to print with the print queue open, the file spooling briefly splashes up and disappears quickly. If I download a PDF from the web, it will not print from within Firefox, but will print from Acrobat or Nitro I have changed antivirus from Eset to Webroot anywhere. No improvement and in between with no Antivirus, Firefox would not print. Any thoughts, as I had to change browsers and I want to get back to Firefox? Help!!

I want to customize shortcuts in Thunderbird using tbkeys but I can't find the right command name.

In the description is written: "Most command names can be found in the main command set file of the Thunderbird source code."

But where I can found all/ more/ other command names?

In my case I want to change:

• "Move to previous UI element" (default: Shift + Tab)
• "Move to next main UI area" (default: F6)

When I went to start firefox today on my MS Windows computer, I got a file error message saying pathway was corrupted (or something like that) and then the firefox app disappeared from my pinned toolbar. When I went and reinstalled it, all of my saved bookmarks and passwords were gone. How do I get them back?

I am the beneficiary (or victim, depending on how you view it) of Cox Communications turning all email services over to Yahoo. Both Cox & Yahoo store messages on an IMAP server.

As seems to be Yahoo's custom, they provided minimal documentation. Last night, in a 3+ hr call to tech support, for example, I noticed that my inbox had exactly 10,000 messages. (I know. It's not Inbox Zero -- I'm a bad, bad boy.) This seems suspicious, so I asked Yahoo's tech support agent about it. At first they said Yahoo puts no limits on messages and blamed Thunderbird for this. Then I showed them my employer's Gmail inbox with 35K messages and said this proves it's not Thunderbird. Then the agent said Yahoo has no limit. Then, apparently after getting feedback from their "support team," they said there's a limit of 10,000 messages per folder. So, even Yahoo's tech "support" seems almost clueless about such undocumented "features."

I know I need to trim the inbox, but I also need to keep lots of messages currently in it. So, the first thing I have to do is to move a large number of messages from the Inbox to another folder whose contents will be fixed.

To do this, I first created a folder to keep the original messages, "Cox Inbox."

Then I created a message filter with the following logic:

• Match all of the following: Date, is before, 4/7/24 (the day before Cox migrated my account)
• Move message to, Cox Inbox

But despite trying this repeatedly (I also tried "Match any of the following"), most messages stay in the Inbox and relatively few make it to the "Cox Inbox." I don't know how to troubleshoot this. Can you help?

Not being able to get the filter to work, I tried brute force. In my Inbox, I highlighted all the messages I wanted to move, pressed CMD-C (I'm using a Mac), went to the Cox Inbox, and pressed CMD-V. But it seemed nothing happened. Again, I'm at a loss as to how to troubleshoot this. Please help.

Today, most of messages have suddenly disappeared from my TB inbox, leaving only the most recent 105 out of approx. 18,000. I have not performed any operations (compacting, archiving...) that could have caused this.

I immediately invoked the 'Repair Folder' command, which did not resolve the problem. Further investigation revealed that the 'Inbox' file ('Profiles' folder) actually contains only 105 messages - seems like the 'Repair Folder' truncated the file!

Fortunately, all the messages are still on the server. My question: Is there a method to 'force' reloading of the missing messages?

Thanks, Ray

New install of Firefox set up with a 'wrong' email account. Tried to use the 'Mozilla account' page to fix this by using secondary email and then making it primary. But the secondary email I want to use is not allowed by Firefox giving an 'Account already exists' error. What should I do?

Since this morning 99% of my tasks disappeared. When trying to reset the lost tasks I remember by converting emails to task or by entering them as new tasks from the taskbar, they do not save and do not show up.

I restarted thunderbird a few times. Whilst doing that there was an update. I think windows. Thunderbird tasks still not working. Checked updates and Thunderbird is up to date.

Converting emails to tasks is extremely important to me.

I'm new to firefox and would like to set cloudflare for DNS over HTTPS but there seems to be an issue. If I set it to NextDNS the connection stays active. But if I set it to cloudflare it goes inactive with the error (NS_ERROR_NET_TIMEOUT_EXTERNAL). I tried setting a custom DNS to OpenDNS and got the same error.

I'm running Manjaro Linux if that make a difference.

Hello

Yesterday there was update in Thunderbird and went well. But today, Thunderbird suddenly asking for credentials and then it went totally blank as in screenshot. There is nothing at all. But incoming mails are still showing up in windows notification and it can be opened as new tab of Thunderbird. I have been searching the possible cause and solution from forum and internet, but no luck. Can someone please help me about this ?

Still using Firefox 78.15.0 esr (64 bit)

Am I correct that the toolbar icon " - | 100% | + " is the Firefox Zoom function? I have never been able to locate a toolbar icon for NoSquint Plus. I also have Theme & Font Size Changer, but it stopped working years ago. Anyway, working fine for many years, automatically setting the zoom on every tab to 150% so I can read it easily.

A few days ago I got into the NoSquint Plus preferences (NEVER OPEN THE HOOD !!!) , and wondered why it was set to chrome API instead of CSS API and changed it to see. That kind of broke it completely. Maybe changed other stuff trying to get it back...

At present, Firefox Default Zoom is set to 150% . NoSquint Plus is default full page 100% and default text only 150% There are no instructions telling me how these 3 settings will interact.

It seems that when I open NoSquint Plus Preferences and change the %, it works on all the tabs on that page, but not on any other page unless I open it & fiddle with it.

How do I get what I want? There is no "return to default settings" for NoSquint Plus.
