After Thunderbird just updated to Version 128.5.0esr today, now all my accounts are saying that the connection is refused. This is coming from three different email services that I have accounts on. I'm assuming it's not an issue with those servers as I can access them just fine with a different email client, and I didn't change any settings. Yesterday it worked, today it doesn't. Only thing that seems to have changed is Thunderbird got updated.

I tried to open Firefox and a message appeared: "Couldn't load XPCOM". I uninstalled the program with Revo Uninstaller Pro and downloaded the latest version. I selected Run as Administrator but there is a message that says "Windows cannot have access to the selected device, path or file. Maybe you don't have access rights". However, I do have access rights. I have checked it multiple times. How can I install Firefox and see it work properly? Thanks

Κατέβασα το Firefox Installer.exe και προσπαθώ να κάνω εγκατάσταση με το Run as Administrator διότι για κάποιον λόγο δεν με αφήνει διαφορετικά, αν και έχω δικαιώματα διαχειριστή. Μου βγάζει όμως ένα παράθυρο το 7-Zip και μου λέει "Δεν επιτρέπεται η πρόσβαση".

Can you please tell me why when I open my Virgin Email Account, the Auto Spell Check does not function? All my other email account I have, the Spell Check works fine, but not on Virgin Email. Yet it works fine on any other Broswer I have. The option Check your spelling as you type box is ticked

About once a week or more, a very small FF icon will appear on my desktop after startup. It will have a string of letters under it, like this one: hqWyUevN . I have never clicked on these things and always pitch them into the trash bin. But I do wonder what it is, what it means, and if it's a security issue of some sort.

Please speak slowly and use simple words. I'm not all that tech savvy.

Thanks!

After updating to 128.4.4esr I can no longer send email - NS_ERROR_FILE_ACCESS_DENIED. I can create a new message, hit Ctl-S to save and I get a dialog box of "Status: Creating mail message..." and a progress indicator that is at 100%. I also get an error of "Unable to save your messages as a draft. Sending of the message failed".

If I attempt to send and email I get the same creating mail message and an error dialog box saying "Sending of the message failed".

In the error console I see

• Bulleted list itemSending failed; , exitCode=2152857621, originalMsgURI=imap-message://andrew@defaria.com/INBOX#67121
• NS_ERROR_FILE_ACCESS_DENIED: Component returned failure code: 0x80520015 (NS_ERROR_FILE_ACCESS_DENIED) [nsIFile.createUnique]

I looked at my ~/.thunderbird directory and the permissions are 700. I'm on Ubuntu 24.04.

I prefer the tabs be below the bookmark bar, and successfully modified the CSS file to do this some time back. Now update 133 has once again pushed them up below the menu bar. What do I have to do to get them back where I want them this time? And why can't you just leave the tab location preference alone when doing updates?

Hello everyone,

How can I delete the automatic username suggestions that appear on websites? Even when I remove the username and password for the website from Firefox's password manager, the usernames still show up. If I simply double-click in the username field, I still get the old suggestions. Deleting cookies hasn’t helped either. Please see screenshot. I anonymized the mail adresses in the pic, but they are completely shown.

Can anyone help me?

Thx in advance Chris

I have encountered the following issue about a year now .I have been using Thundebird some years now and I have created my contact list . Even though I have added in the address book all the contacts I needed and named them as I wanted. When I receive a mail the correspodent appears differently from what I have named the contact.Propably as the person sent me the email have named himself.The same applies in sent mails as well.No matter what I did ,it seems like the database from the address book is not linked to the mail database whatever I do. Please advise

Hello, "desktop view" is very useful, and I use it for LinkedIn because the "mobile mode" is shitty (I guess to make/force people to install the proprietary and closed source LinkedIn app).

I found that "desktop view" is stopping working while activated, when you always keep a tab opened for days... I have to close the tab and open a new one to make "desktop view" working again.

I found too that "open in a new tab" action is not inheriting the view mode of the parent tab and that an issue when browsing the same website.

Could it be possible to have "desktop view" enable by default based on visited website?

I have created a new Firefox profile. Now I want to copy my settings of the Developer Tools to this new profile. This should also include the custom device settings for the Responsive Design Mode. Is there a file (or files) in the profile-folder that contains these settings, and can I copy this file (or files) to the new profile? I found this link about copying profile files, but it doesn't mention devtools settings.

Restarted my PC and on boot found all my containers deleted. Bookmarks are fine. Browser settings are fine. Other Extensions and Addons are fine. Tabs from the last session were stll there. Everything else is all good. FireFox Multi-Account Containers is the only thing that's gone wrong.

Looking at my containers.json (my best guess on what to check) they're all back to default. There's no "Old Firefox Data" folder on the desktop.

This happens ~3 times a year usually after an update or if there's a sudden shutdown due to power loss.

I've used FireFox Sync before and rather than helping, it ruined everything for no apparent reason. It duplicated the current containers, restored and duplicated old deleted containers and sites stopped using their designated containers.

It sucks. It really really sucks.

Is there a way to make local backups of containers and their designations? Just knowing exactly what to backup would be a massive help and make this a lot less distressing.

Bonjour, Impossibilité d'ouvrir les vidéos sur portail orange depuis plus d'un mois. Pouvez-vous prendre en compte ce dysfonctionnement pour la prochaine mise à jour de firefox? A vous bien cordialement.

When I try to connect to a different site when trying to make a purchase on paypal say the redirect crahes almost everytime. It is getting so bad that I amthinking of dicthing firefox and going back to edge.

Hi Thunderbird-Team, I am using Thunderbird 128.5.0esr (64-Bit) on Linux (openSUSE Leap 15.5). When I want to attach a file to a written e-mail the file-selection dialog does no longer offer a line-edit-control where I can copy-paste an absolute path to the attachment file. I always have to click through the full directory path in order to specify the file that should be attached. Is there any chance to input a file path via keyboard or just by mouse-paste? Kind regards, Ove
