Created several email mailing lists. Stored them in the Personal Address Book (PAB). I'm sorry, but Thunderbird doesn't seem to work like any other email client. How do I address an email using one of those mailing lists in the PAB. Tried typing the whole name of the mailing list in the To: field. Didn't work. I'm not entirely stupid but it doesn't make sense to me.

Error message 'side by side configuration error'. I've been advised to re-install Thunderbird but not sure if I will lose my many thousands of emails and my address books etc.

A few months ago

If I deleted an email or moved it to another folder - on my apple app for any of the accounts that I also have on thunderbird

The changes would sync seamlessly - a few seconds after I deleted or moved an email on my apple iPhone mail app - on my laptop - thunderbird would show the same changes.

The same worked the other way if I deleted or moved an email on thunderbird on my laptop - my iPhone would show the changes in seconds.

However now if I do the same on my iPhone The changes do not show up at all.

BUT if I do the changes on my laptop - they will show on my iPhone. It just doesn’t work if I do the changes on my iPhone.

Is there a reason for this?

Once again Firefox has decided to take over and change all my settings! I had finally managed to prevent it updating, as each and every time I had to reinstall all my setting and extentions from scratch. Today, it decided to clear all my preferences and change itself to its own default settings. OK, so I can change my profile option, except all three are using the same defaults: I appear to have lost all my settings and extensions entirely. OK, I'll copy from my backup, but once again the three backup profiles are being overwritten with the defaults. Even my third backup of last March overwrites to the defaults! How and why is Firefox managing to keep overwriting my defaults to its own preferred settings? How do I stop it doing this and regain my own preferences?

I also tried Sync and now I am getting bookmarks from over five years ago! And once again my settings are changing to the defaults. Surely a Sync should overwrite with the current bookmarks and settings not just keep adding more and more. I am now in a right mess again. Back to losing everything with updates. I am a great believer in the 'if it ain't broke don't fix it' mentality, but Firefox has broken itself and is refusing to allow me to change to how it used to be! How do I restore my own preferences and prevent Firefox from changing them to what it wants.

this interface uses pop3

When emails are pulled, I can see that it pulls, let's say, 50 messages, the notification shows 25 new messages but the inbox only shows 10. I have looked everywhere for the "missing messages" but don't see them anywhere. I have also had some people tell me that they sent an email response (so they were not entering the email address) and I don't see it.

What could cause these differences?

Within 24 hours this weekend I was notified by my anti virus application (Avast) that they are no longer supporting Firefox browser (to concentrate on Outlook and Chrome), and a political news website that I frequent (Meidas) blocked me with a "captcha" type puzzle. The website said my browser was mimicking robot or bot use. I was presented with a puzzle requiring me to slide a tab rightward. It repeatedly told me I had slid the tab incorrectly. I believe all of this happened after an update of Firefox about the middle of last week.

I have two monitors; I keep my taskbar on the right monitor and run Firefox on the left monitor. For some reason, whenever Firefox gets minimized, the window moves to whichever monitor the taskbar is on (I've done some testing to confirm it is specifically the monitor the task bar is on). Because I also run a program called max.to to separate my right monitor into different sections, this action of minimizing to, and restoring to, the wrong monitor is also resizing my Firefox window.

Is there any way, any option I've overlooked, that would get Firefox to minimize and restore to whichever monitor is is actually running on?

I've attached an image that shows, as best I can get it, the window moving over to the task bar monitor when minimizing.

Hello,

Please check the attached picture. My "Blogs & News Feeds" contains an empty "All jobs upwork.com" folder and I can't figure out how to remove it.

I have moved Thunderbird from the new Microsoft Outlook and I am very happy with Thunderbird except for one thing.When sending an email I often get the error message:

"your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. You can retry or save the message locally to Local Folders/Sent-jemsym@aussiebb.com.au."

How can I correct this? I have checked the outgoing SMTP details and have changed a couple of things with AussieBroadband. the problem remains. Can you help?

After I boot my computer, I can access any of the sites I usually use, but only once. If I then close the site and attempt to open it again (or to open any of the other affected sites), I get the following message: " Secure Connection Failed

An error occurred during a connection to phoenixcommons.cohousing.site. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

The site shown in the error message above is the one I most ofen use, but other very common sites (e.g. Google.com) exhibit the same problem:

" Secure Connection Failed

An error occurred during a connection to www.google.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

Yeah, right. I'm supposed to contact Alphabet and inform of the problem?

In contrast, some sites (e.g. The New York Times, The Washington Post) are not affected.

I can paste affected URLs into another browser (I used Brave) and access them with no problems.

First post. I was trying to target a Thunderbird forum but I get vectored to Mozilla which seems to be more focused on Firefox. Sorry if I'm in the wrong place.

First, it was my impression that a global Inbox could be POP accts only. But my global Inbox has a POP acct and an IMAP account. I'm not sure but this might have happened when I converted one of my POP accts to IMAP. Am I wrong about this theory? Going forward, I'm going to refer to this IMAP acct as the "bad" one.

As a result, my bad IMAP acct that appears in the global Inbox has no Inbox of its own under its account. What I'm looking to do is get the bad IMAP Inbox out of the global Inbox and back into its account in my sidebar.

There's nothing wrong with my e-mail but I want to keep it that way. I have another IMAP account (aka "good") and as a result of my situation, I have to look at the bad Inbox and the good Inbox of the two IMAP accounts in different ways in the interface and it annoys me.

I've looked at the account settings. The good IMAP acct has the personal namespace "INBOX." whereas the bad IMAP acct has the personal namespace "". I've tried changing the bad personal namespace to "INBOX." as well but I also have "allow server to override these namespaces" and it won't stick. I don't understand IMAP well enough to be confident about making more changes without getting advice.

Hope this isn't too confusing.

BROKEN: Videos automatically play upon landing on a website. I don't want video autoplay. I had that FIXED at one point, but with the new update, all of my settings were discarded, and now I'm back to square one. I do not want video autoplay! Now, on to the next question: many complaints have been lodged on various 'help' pages and forums describing the same problem; my question is, in light of all of these complaints, why hasn't Firefox FIXED this problem and issued an update with the repair patches?! On my version of FF, Mac 126, all video controls in settings have disappeared. WHY? Where did they go? Not that they worked anyway because we had to muck about in about:config with various patches WHICH NO LONGER WORK ON MY MAC! Why is there not a simple ON/OFF switch, in Settings, for those of us who want the choice?! When are FF boffins going to FIX this to our satisfaction, with a WORKING, simple-selectable solution? I await a reply from a knowledgeable Firefox technician, one who preferably works on this part of the browser, please. Help me understand, or make me happy, preferably both.

Please assist,I have 4 Email address with Thunderbird & regardsless of which email I use ti send a reply,it comes up with out going server SMTP error this all happened when I added a 4th Email address Thank you Darryl

Copy/Paste not working- ASKED MANY TIMES AND ISSUE STILL PRESENT

get the same old useless answer, refresh. THAT DOES NOT WORK

this platform is really past its use by date, TOLD BY BANK TO AVOID AND GOV. SITES!!!

when it comes to buying a new pc I will switch out to another browser, shame a good 12 years with FF.

I hve discussede the matter with my banks IT-department, but they answer me that recently they have heard about the same problem concerning Firefox login and said that the problem have to be fixed by Mozilla/Firefox

Up until the last few days I had bookmarks, shortcuts etc saved on my phone and Firefox browser. Today I went to click on a shortcut that I regularly use, only to find it had been completely deleted from my phone! How did Firefox get access to my phone to remove these and to completely clear my history, bookmarks, shortcuts etc??? I never gave permission to access or to delete anything from my phone or browser!
