I have been using Thunderbird to access my comcast emails. I never had a problem with it. However, this afternoon, just out of the blue Thunderbird cannot download my emails, the following message popped up: "Login to server mail.comcast.net with username xxxxxxx failed." Then Thunderbird asks for a new password. When I enter the still correct password, it displays the same error message. I did not change anything in the settings before this error message popped up. I tried ChatGPT to get some answers, but whatever I changed it had no effect. I am attaching a screenshot of the server settings (I have of course removed my username). I would be grateful for any advice as to how to fix the issue. Thanking you.

In the older K-9, when one changed the active account, the inbox for the newly selected account would just be shown immediately. No need for any other operations on my part.

Now I have to tap on the inbox to get there. This seems an awful nuisance and offers little to anyone, I suspect.

Is there some way to get the old K-9 behavior?

Thanks!

On those somewhat rare (but not all that infrequent) occasions when Firefox locks up and hard crashes and all 6 or 7 of the windows that are open go up in a puff of virtual smoke, (each with their uniquely organized selections of tabs) - upon a restart of FF all of the windows return reliably.

But when a clean shutdown of the program is initiated only the "top" window or two returns, and as far as I've seen there is a limited number to the "Recently Closed Windows" available to recover from the History menu.

Clearly the state of the applications windows is preservable - why not recover all of them, similar to the "on startup pick up where I left off" setting for pages and tabs.

(Incidentally Adobes applications exhibit similar behavior - the system actually works better and can recover the entire "workspace settings" but only if the power is abruptly cut off, (and no tedious waiting for updates to complete as a bonus!))

Be nice. Our volunteers are Mozilla users just like you, who take the time out of their day to help.

Be descriptive. Saying “playing video on YouTube is always choppy” will help us understand the issue better than saying “something is wrong” or “the app is bro ken”.

Follow through. Sometimes, our volunteers would ask you for more information or to test out certain scenarios. The sooner you can do this, the sooner they would know how to fix it.

Why are all GetResponse redirects causing 404 errors in Firefox but not in Google Chrome?

Here is a primary link that feeds GetResponse https://app.getresponse.com/click.html?x=a62b&co=IfVvoP&lc=hXaPFo&mc=9F&s=B0OSZKW&u=QELup&z=EhPrtjL& if you want to see for yourself.

Hello,

I am currently on the latest version of Firefox Beta for Android, version 146.0b4.

For some time now (6+ months), this installation of beta fails to sync my bookmarks from or to Mozilla's servers. I've verified that desktop Firefox and Firefox stable on Android will still sync.

It took me some time to notice this was the case, and at first I hoped it would resolve itself, but it hasn't. I have many newer bookmarks on this installation of the browser, and if I reinstalled in an attempt to fix this issue, I would lose these bookmarks.

How can I keep my newer bookmarks on mobile, while also fixing the sync functionality? There doesn't seem to be a way to backup bookmarks on Android other than sync, which isn't working.

Other sync data aside from bookmarks is still syncing fine. I tried signing out of Firefox on all devices, then signing back in, but that didn't resolve the issue.

This is a new Fedora-42 desktop, upgraded (dnf upgrade) today. I installed Thunderbird today (dnf install thunderbird), after doing the operating system upgrade. I tried to add my yahoo e-mail account. Settings are as follows:

• create accounts in the new Account Hub is unchecked (off).
• accept cookies from sites is checked (on).
• remember password is checked (on).
• I'm using "IMAP".

When I click "Done", a separate window pops up in which yahoo asks for my password. After entering it, yahoo says "Something went wrong", and gives no other indication of what the problem is.

If I instead "Configure manually"... I tried both the default hostnames and "export.imap.mail.yahoo.com" for the outgoing server. I tried both "Normal Password" and "OAuth2" authentication methods.

In all the above cases, I get "Unable to log in at server. Probably wrong configuration , username or password." with a yellow background.

I see nothing of "Edge Too many requests" as was happening to several people recently.

How do I add my yahoo account to this new Thunderbird on Fedora-42?

I've been unable to use TB since July/August 2025. I don't have detailed documentation of the details, but my recollection is that an error was occurring whenever I would try to send an email. My troubleshooting led to the possibility that the problem was with the SMTP protocol.

  Please let me know whether anything more was contributed here in this forum. Meanwhile I will install TB again and try to re-created the problem.

Thanks for your help, SweetTasha

I just updated my browser less than a week ago. Today I got another notification for yet another update. This logs me out of everything.

WHY so many and so frequent are firefox browser updates. I am about to stop using this brower if it continues. It's very disruptive!

Thank you for your attention to this.

Hi,

I am trying to remove a large number of e-mails from my Inbox. The standard advice says to hold down Ctrl or Shift and select e-mails, then right click, and choose rubbish bin symbol to delete. The advice says you will get a confirmation message, but that doesn't happen. Only the e-mail right clicked on actually deletes; all the rest stay put.

I have tried deleting the trash file to force it to recreate. I have tried updating Thunderbird, but I'm already on version 145.0. I use gmail.

Does anyone know of a working method for doing multiple deletions?

I wrote yesterday but my post doesn't appear today. Today I got the message about bookmarks and history not functioning and eventually found something in Firefox that said it was probably due to "some security software." I have now gone into Windows settings and my security updates are done, but I have no idea what I'm supposed to do now. This is an extremely annoying and disruptive issue. I see that several other people are experiencing it, so it's interesting that the note next to their posts state that no one else is having the same problem. Can someone please help us all to get our bookmarks and history back?

Hello!

1. I have a question about Thunderbird. Why does saving an email to the local hard drive take significantly longer in newer versions, for example Thunderbird Setup 144.0.1, compared to older versions like Thunderbird Setup 115.18.0? What could be the reason for this? How can this issue be resolved or what might be causing it?

2. Could you please inform me which parameters in the advanced settings have been added or changed in the new Thunderbird version 144.0.1 compared to version 115.18.0? Also, what might cause a significant increase in the time it takes to save a received email to the local hard drive in the new version?

Thank you in advance for your help!

I was trying to change the time emails are kept on the server so I went into "Account Settings" and now Thunderbird is locked onto this page. I get a "Mozilla Thunderbird not responding" message when I try and click on anything and I can't get out of this page nor access my Inbox. I've tried starting Thunderbird in Safe Mode which didn't work. I then uninstalled and reinstalled the latest version of Thunderbird but when it starts it goes straight back to the frozen "Account Settings" page. I've checked my profile and there is a new profile that was created with today's date. There is also a profile from June 2025. If the old profile contains all my emails and folders up to yesterday, that would be OK.

Every so often a message pops up that a folder can't be compacted because it's in use.

I don't understand why TB bothers users with this message. Compacting folders is supposed to be invisible to the user. It'll get compacted eventually, so no user action is required.

If I'm missing something, please educate me.

And if not, what's the best chance of getting it removed? Should I submit a bug report and argue that it's a bug in the design? Is a suggestion likely to do anything?

I've been wanting to access Thunderbird's encryption ability on both my laptop and desktop. However, in setting up Tbird on my laptop I notice the user Profile should stay on one computer. Can I use the same Profile on more than one computer using the same source and password? Can I open a new profile on a second computer, even though I would have to use the same email source, a local provider? If not, is there an online source of email data I can use on Tbird on my laptop. Thanks much, Bruce Bartrug
