4 of my many T.Bird email folders somehow lost their email contents (about 50 emails). I have an older T.Bird email backup and want to only reload the 4 empty folders using the backup. I want to keep any emails that may be in my other current folders but not in the backups. I am not sure how to do this.

If I copy the same named T. Bird email root directory [b0mdofvn.default] back up folders into the current email root directory, I see the replaced emails very briefly and then they self delete, leaving the folders empty.

How do I fix this?

Hello, I got a tale of two computers with Thunderbird on both. First, I will start with my HP Laptop, its my primary computer due to its speed. I went to check my emails this morning. I double click on the TBird icon on my desktop. It does not open. Waited a few seconds, tried again and again. Finally, a folder containing pictures opened up. Then, I went to open FireFox, and that same folder with pictures opened. I tried this like five times and the same thing happened. Then I got to thinkin, when I went to shut it down the other day, it said "update and shut down", so I did. Now that I remembered the update, I decided to go back in time to when the laptop was running real good. So I did that recovery, in doing so, it wiped out some of the applications I had on my computer, such as FoxFire, Thunderbird, Adobe, HP printer, CCleaner, and probably others that I seldom used. Somehow, I got to the point where I reinstalled Thunderbird. The only thing is, it would not let me in. When double clicking on the icon, it took me to a page that just wanted my name, email address and password. I enter the info, that page stayed open and added a few more items to the page, such as IMAP and POP3 stuff. IMAP was already selected by Tbird. I then had the option to click "done" . In doing that, it said "Unable to log into server. Probably wrong configuration, username or password" So there's that. Cannot even see the email program. Second part of the mystery, I have an old Gateway desktop. Its slower than slow. I only use it in emergencies, as the above scenario. I fire it up, wait about 5 minutes before I open Thunderbird on that. Guess what, it wants a password. Whats different about this deal is that the email opens, and I can see all my previous emails, but cannot receive or send. I have no Idea whats going on, unless its my deceased wife coming back to haunt me...I don't know.

I have a folder set aside for a non-profit I volunteer for. I want to backup all those emails separately so that they are 'easy to access' - it's a regulation. How??

I have several users who are migrating email from Outlook, and they want me to confirm if the Thunderbird export will bring over:

• drafts
• sent mail
• deleted mail
• any subfolders in the mailbox

Thank you!!

I heard that the newest version of Firefox (which I have not upgraded to yet) has a feature that makes it easier to accidentally visit a website whose URL is on the clipboard. I googled to find out how to disable it, and the Featured Snippet said "go to about:config and change clipboard.autocopy to false." Sounded simple, so I did it, but subsequently found out that the article it quotes from is 10 years of age!

My first question, then, is: what does changing "clipboard.autocopy" to false do if it doesn't turn off the brand-new feature?

The second question is, how do I disable the new URL Paste Suggestion feature? Will setting "clipboard.autocopy" disable it? In particular, I want to make sure that the browser does not pre-load or pre-fetch the clipboard URL, and in fact, I wish to pop up a dialog box any time I do "paste and go." People often copy URLs from e-mails to research them before visiting them directly; jumping directly will increase the likelihood of visiting an imposter site.

Firefox is not opening. Every time I try to use it, I get the message:

" We're sorry. Firefox had a problem and crashed. We’ll try to restore your tabs and windows when it restarts."

I have submitted the crash report: Crash ID: bp-51f17766-7a20-41dc-ae3d-27ab10240501

I am running it on Fedora 40.

Thank you!

I downloaded Thunderbird from Microsoft store. I enter my name, email and password. The first message was "Configuration found in Mozilla ISP database", but the last message was the Error: "Unable to log in at server. Probably wrong configuration, username or password".

Email is from gmail. App version is 115.9.0 (64-bit).

I had ab account that I deleted. however the system still tries to log into the server to see if there are any new messages (for the deleted account). The account does not exist however and it cannot access the server so it hangs waiting for a response that can never come.

How can I stop Thunderbird from doing this?

When I try to send emails, I receive this message. "Sending of the message failed. An error occurred while sending mail. The mail server responded: [M1] Authentication required (6aecbed3-07a6-11ef-9de7-83bcbd00a978). Please verify that your email address is correct in your account settings and try again". I have checked as requested by this message, and everything appears to be in order. Can anyone help with this issue, please?

Have two computer with same email. My Wife's computer password got corrupted and unable to get messages. I deleted TB and deleted any reference to Thunderbird in the registry. Turn off and restarted PC, downloaded new install and run and all the setting from before automatically were in place and still could not get pass the password issue. My computer does not have any password.

My wife's PC, under setting, does not have any saved passwords or a Primary password or even the "Use a Primary Password" checked. If it is checked there is nothing there. It just will not get passed the password issue being always asked when trying to "Get Messages".

How do you get rid of all the infor, setting, password requirements and to be able to restart with a clean Thunderbird install or get passed the password issue? Making my brain hurt.

Thunderbird fails to access comcast.net email accounts after years of working correctly. Version 115.10.1. I have tried changing the password many times after talking to Comcast support. The best they can do is suggest I contact you.

Hi Guys! Huge fan of Firefox since the early 2000s when I first learned about it. Way more secure, efficient, and lighter than any other browser (IE, Chrome, and now Edge). Firefox is my first download on every new device and my go to even on my iPad.

I've been getting this error message lately and I don't know what to make of it. My saved tabs are working normally (email, work, streaming entertainment). This automatically comes out on ever new start / re-start (Firefox is my default) on separate tab but I am not opening any new website. It's been 2-3 days. At first I didn't mind it but its consistently happening and not just a one time thing. I already cleared my cache data. I've also ran a scan and it's come up clean (I have a paid BitDefender subscription). It's also not the local ip of my machine.

So any help would be great as I really don't want to leak any personal data or have any viruses.

Thank you for your time!

I use Firefox as my browser and used to be able to go a web site or to a link from an instructor and when I clicked on the link or entered the class I was attending, the Zoom meeting would automatically open. That doesn't work anymore. I have to "join via browser but I don't have the meeting id. Why has this become so difficult? Zoom denies being the problem so now I wonder if it's the browser.

The increase happened here: /storage/permanent/chrome/idb/3870112724rsegmnoittet-es.files/

79 files taking 590MB created in 3 minutes, out of nowhere. Why were all these large files created?

Using Linux Mint, Firefox 125.0.2

Whenever I type in a website URL in the search-bar, first of all, the drop-down menu of related searches and websites does not show up. When I press enter to confirm that's where I want to go, nothing happens. The URL just kinda sits there, no loading circle or anything... Just a blank page. Only two of the icons on my toolbar works. The "Account" icon, which takes me to my Firefox settings. And my Extensions icon. Clicking the three little lines does nothing. The only websites i have been able to get to work at all are the settings page, and the Firefox troubleshooting page. I'm using Version 125.0.3, I tried using the browser both with and without hardware acceleration with results being unremarkably the same. I restarted Firefox and my computer multiple times to no avail, and the only thing I could find out of the ordinary was an error with Importing data from Microsoft Edge, which was not something I consciously wanted to do, but there was an error that popped up regarding that when i went to the settings page.

All that being said, I'm confused and at a loss for options, and could really use a Mozilla Staff member or someone who knows what they're doing to work me through this.

Hello, have been scratching my head for a while on this one. Have a freshly setup install of Debian 12, using Sway (wayland) as my Window Manager. I am really struggling with slowness in Firefox, page loads take easily 15 seconds whereas loading the exact same page in another window at the same time with Chromium Debian build has near instantaneous load times. I've tried the following troubleshooting steps: - Created a new firefox profile - Tried "Troubleshooting Mode" in Firefox - Disabled ipv6 in firefox about:config and in Debian - Tried different DNS servers - Tried different non-debian specific builds of Firefox - Tried Firefox Beta and Firefox Nightly for Debian

None of these steps made any difference, and Chromium has continued to be significantly faster. Am really stuck here and would love to get to the bottom of this as Firefox is the only browser that works with a HiDPI display in Sway without blurryness. Happy to provide any and all diagnostics and reports that are needed. Thanks in advance!

EDIT: It seems to be some kind of networking issue, using a VPN solves it. But still doesn't explain why Chromium would behave differently.
