Your system has now blocked me from accessing Jacquie Larson e-card site to receive or send e-cards. Today it blocked me from opening my statement from Edward Jones. Both of these are sites I have used for years and do not pose a threat to my computer. How do I get rid of this aggressive blocking and get back to reaching these websites?

Att made me change my account password. Now Thunderbird cannot access messages. I have entered the new password in out going and incoming but there seems to be more to this than that because nothing happens. Where do I have to put in new passwords? Thanks so much. Marjorie

Hello! I recently used the function to create my own theme for the browser, after a few months I wanted to install another theme (not a custom one, but from the store) and encountered the problem that after re-entering the application my custom theme returns, but another one is specified in the settings, and so after each re-entry.

On my Xfinity login, I have multiple folders to sort email into. When I installed eMClient, those folders were automatically created and are kept in sync across all clients.

When I installed TB, the folders did not appear.

Is there a way to make them appear and to be synced with Xfinity?

Is there a particular setting that needs to be/can be made so that email deleted from TB install on one PC also deletes from an install on another PC, on the Android app, and via the Xfinity email website login?

I'm trying to install thunderbird on new laptop and can't remember password for my email account. I also need to copy some locally stored email folders and don't know how to do that

Hello, I synced all my gmails to thunderbird (many). When I tried to archived some messages, I found they are in my main inbox. The all mail folder does not contain them. I am trying to restore allmail to contain everything. Thunderbird keeps crashing, it seems like it is crushed by the load of my messages. Further, the archived messages are now missing from my gmail account. Please help! Thank you, Steve

I have been trying to migrate all my accounts to maildir, but Export/Import doesn't work.

Even after I ensure that the old profile is backed up in another location and deleted from the previous path, and then I try "/mac path/thunderbird -P" and the first thing I do is set "maildir" as the storage for new accounts in settings.

After that, I imported (only accounts and settings) from the backed-up profile .zip, but the mail store type per account gets overridden by the old profile, it seems, and is set to "mbox" (uneditable).

Is there a way to retain the settings except for the mail store type? I am fine with entering every password again; I just hope to not have to do all the config again (settings for subscribe, junk, etc… and… what not) again for all those accounts.

Can I do it via prefs.js, etc.? If so, will I have to modify something in those files? What files will be needed?

In Outlook it is possible to have the favorites fixed in top of the folder pane column. This is very handy when moving emails from the inbox to often used folders which fall outside the displayed part of the folder pane. (You don't have to scroll back if you want to display the content of the inbox). I cannot find a way how I could do this in Thunderbird. Is there a way to fix favorite folders in top of the folder pane?

This question was asked 10 years ago but I can't find where a fix was ever found for the latest version of TB. I would really like to keep the favorite folders in sight while scrolling down through the other folders I've created.

Is there an add-on for this? I searched without finding one.

We have an email on one of our computers that was removed and when that computer starts up it tries to access our website and then our web host blocks our IP address. If it tries to access our web site more than 5 times in 3600 seconds we get our IP address blocked.

I have looked everywhere in that computer to try and find where the culprit email is located, but I have found nothing.

We are running version 140.2 on Widows 10. I really don't want to reinstall Windows, but!! A,d I have been working on this for 3 weeks and it took me 2 weeks to locate the computer that was getting me blocked. Our IP address has unblocked at lest 20 times.

I still get all my messages and everything seems to work correctly but when I open my inbox I get this message I have a huge amount of free disk space, and I empty my inbox and spam daily, so I don't understand this: "The folder on inbox ruthjh@gmail.com cannot be compacted because writing to inbox failed." The only problem that shows up is that occasionally I don't instantly get the subject line but keep the one I had clicked before.

I downloaded thunderbird on my android phone, and imported settings from my laptop. My personal gmail account has been working fine. However, my school microsoft online account has not been able to send emails. it can receive emails, but whenever I try to send an email, it just stays in outbox gives an error message:

Failed to send some messages Authentication unsuccessful [BL1PR13CA0340.namprd13.prod.outlook.com 2025-09-01T13:04:36.305Z 08DDE84F8D3B37FC]

or

Authentication failed Authentication failed for [my email]. Update your server settings.

Given that the smtp server settings are exactly the same as on my laptop since I imported from there, I don't know what to change to fix this issue.

Für Android gibt es bei E-Mails K-9. Ich habe noch keine Lösung für Kalender und Aufgaben gefunden, die mit Thunderbird unter Windows/Linux synchronisieren. Kann mir jemand dazu Lösungen anbieten?

Firefox kept eating my RAM, running dozens of processes. I have gone into about:config and set the dom.ipc.processCount to 1 - then I restarted Firefox and found 5 processes running straightaway before even using the browser. I closed it down and have started it again and now there are 11 processes running with just one tab open. Firefox(9044) Utility(7552) JavaScript oracle Network (15912) Data Decoder (11364) GPU (18744) About pages (12536) Preloaded new tab Extensions (20544) Preallocated (16132) Preallocated (13780) Preallocated (16044)

The problem repeats on three different computers which are not infected with malware. One computer with slightly less RAM I now cant even use Firefox at all (though all other browsers work fine) because the tabs constantly crash due to the high number of processes. Is there any way to set the process limit low in a way that Firefox actually responds to?

Hello,

I run TB 141.0-64 with Windows 11 and am on the Release Update Channel. I've had Spam sorting problems for about a year, through many TB updates, and many Windows updates.... I run SFC, and DISM, regularly.

The Spam difficulties are of two types: Many messages appear in my Inbox, are marked as Spam, but are not moved to my Junk folder, so, I move these to their Junk home manually. Also, many messages appear in my Inbox that are obviously Spam, but are not marked as such, and, of course are not moved to my Junk folder. For each of these, I click on my Junk button, and these messages jump over to their Junk home to meet their new friends. Often, messages of this second category, are identical to messages that have been properly moved to my Junk folder earlier.

Finally - The the Spam sorting problems I've described, are intermittent. I can sometimes go for many hours with my Spam tools working as they should. Then, the Spam sorting system fails again, as I have described.

I express my thanks, in advance, for any assistance that you kind folks might be able to offer,

Lothar
