Thunderbird Community Forum

I need a filter on a message to FULLY FINISH before a next message starts to be filtered. The "help" (quotes because it's an abyssal crap) says that simply ending the filter with Stop Filter Execution does it - but that's simply NOT TRUE: calling a console program in the filter, I can see five DOS boxes opening at the same time with five messages matching, i.e. the filters on the next message DID NOT wait! So... what can I do??

All of the above is because I'm getting "Too many simultaneous connections on the server". I'd like to limit the concurrency, but it only seems to be possible in IMAP, while this connection is a POP. Why only IMAP??!

As the topic says, the message list turned from the usual dark-mode look, to a full black background after updating to 151.0.

Was this an intentional change? How can I revert it?

Until recently the folder pane could be sized or hidden via the double-headed arrowed cursor. Shortly after the 151.0.1 update this stopped working. All suggested solutions have not worked. A full uninstall (Revo Uninstall) and completely new profile has not fixed the problem. Folder pane only responds to the menu setting and is only Open/close but no sizing.

My filters are broken in Thunderbird. I have deleted and recreated some to no avail.

I moved some folders from Local to under my inbox and it said it would update the filters automatically, but noticed it didn't do this. Looking at the Filter Rules it just left either the first or second column of Perform these actions under the Filter Rules empty rather than updating them. I tried moving the folders back to see if the filters would then work, but it's a mixed bag. Some filter properly and others only go under say Newsletters, but don't filter into Newsletters > Adobe for example. Others just sit in the inbox. I've tried moving some rules to the top of the list hoping that'd give them priority to be run first, but it hasn't helped. I have a lot of filters setup to help me track newsletters, classes, meetings, job applications, etc. I've missed some responses for a couple of days because of this. Any suggestions?

So I don't miss anyone, thanks in advance.

All of a sudden every time I open something in an email it automatically creates a new tab. When I delete what I have open it takes me out of my email account and I have to delete the tab to get back to my remaining emails. I have changed nothing so I am confused as to why it has recently changed.

Hi,

I am trying to edit my message separator line (which I added many years ago). Now there is a big gap in the line and messages. How can I reduce this gap please? Any advice?

Regards,

LS

I have one file folder that I moved certain files to that once read, they are not visible or listed in the folder. The folder massage count is 296. When I move an email into the folder and it is not read, I can see the message. Once read, it disappears. I can filter by attachments and contacts and see some but not all of the messages.

When I attempt to write/ reply/ reply all/ forward, the toolbar at top shows only the slanted pen symbol and "Write -- nothing below. So no "Send" button. The full toolbar that I am trying to recover is attached which I copied from a second computer. When I write click that "Write" bar at the top, noting in the drop down menu had any effect. Help/About says I am "up to date" running 153.1.0esr (64 bit)

Subject: Persistent Column and Folder Layout Issues — Not Being Saved Between Sessions

This is a follow-up to my previous support requests regarding two ongoing problems that significantly impact daily usability.

Column Settings I manage multiple accounts, and my preferred column layout is: Starred, Read Status, Attachment, Subject, From, and Date/Time. I do not use Threads, Correspondents, or Spam Status columns. Despite setting these preferences repeatedly, Thunderbird fails to retain them. Every day I must spend time reconfiguring columns across some or all of my accounts — the state varies unpredictably from one session to the next. This is a persistent, daily frustration that costs meaningful time. Most other major email clients save and reliably maintain column preferences. I'd expect Thunderbird to do the same.

Folder Panel Layout Two problems occur regularly when Thunderbird loads:

Folder order — Standard system folders (Inbox, Sent, Drafts, All Mail, Trash, Spam) should appear at the top of each account. Instead, Sent, All Mail, Trash, and/or Spam are frequently scattered among custom folders, with no apparent consistency.

Folder expansion — Most or all folders load in an expanded state, exposing every nested sub-folder regardless of whether they contain unread mail. This creates unnecessary visual clutter and requires manual collapsing each session.

Again, this behavior is uncommon in other widely-used email clients. Summary These are not one-time glitches — they recur daily and represent a significant usability gap. I'd appreciate confirmation that these are known issues being tracked, or guidance on a reliable fix. Reformatting the interface every morning is not a reasonable expectation for users.

Hello All, The opening email changed to a reader that works, but I'd prefer to use the "Classic Reader" by default. Searching the settings hasn't turned up anything that sounds right. Is there a behind-the-scenes file that I need to edit to resolve this issue?

Enclosed are jpg copies of the current sets of filters failures in my TB email program.

TB Error0 shows the 6 emails that have arrived and are placed in the INBOX. However, each of these has a corresponding filter set up to move them upon arrival to a separate subject email mailbox.

Note: If I highlight the INBOX and then go to Tools > Run Filters On Folder ... all of these INBOX email messages will be correctly filtered and moved to their respective email mailbox, BUT each of them is shown as having been "read" and unless you pay close attention, you may not know where these INBOX emails were sent.

I am also enclosing TB Error1 & 2 that show the last couple of days message filtering errors.

I can find nothing wrong with how each of these filters are set up, yet they seem to consistently fail to operate when new emails arrive.

Note one of them is for incoming emails from ... schiffsovereign.com. I have edited this filter repeatedly, even deleted it and re-input the information. Yet the filter never takes hold and does what it is designed to do. I am enclosing a jpg of that specific filter as TB Error3

I am looking for suggestions on how to fix this problem.

Thank you and best wishes,

Bonjour, Je vous promets que je vous fais un don dès que vous aurez mis fin à votre publicité mensongère à propos des Dossier récents : ils ne sont jamais triés par ordre alphabétique, quelque soit le paramétrage demandé.

When I click an email open, More than HALF the screen is taken up by a fixed Header. This leaves only 2" high to read the email. Can I change this and get a page to read the mail? I do not half a page to see date and time etc. an no space to read the mail. Its terrible!

I have Thunderbird on another PC that shows the incoming emails with the contents with the contents displayed under the email list, yet on my new PC I cannot seem to get that setting. I have to double click an email and it opens a new tab. I have used your help and also YouTube to no avail.

I use Thunderbird on a PC. It has began to open evry e-mail I select as a pop-up window. This is unusual for me, and I do not want it. I just want to open the e-mail inside those windows that already exist on the screen. It has been like that before. In settings I have selected to open e-mails in an "existing window" Is this korekt? Finally one more question: can I write in Danish here? It would be easyer for me to explain my problem in danish.

Whenever i send a message , it is saved to the 'inbox' previously it would be saved "sent mail". I have verified that TB is configured to save to sent mail but the msg is saved anyway to inbox.

Can some one explain how to get back to saving sent messages to sent mail folder.

In all honesty I find it frustrating to keep moving msgs manually.

At some point recently, Thunderbird started ignoring the page range I specify in the print dialog box. I regularly have documents that are 4-5 pages, however I only need the first page printed. So in the print dialog, I set it to double sided printing, and to print only pages 1-2. In the past, it would only print a single (double sided) page...recently, it started printing all of the pages, and ignoring the setting I provided. Any help would be appreciated!

Currently using TB 153.0, Win 11 on desktop PC.

In past versions there was a progress bar on right end of the status line, along bottom edge of the screen, that showed progress while TB was compacting folders. That bar hasn't been visible in last few updates.

When prompted today, I allowed TB to start compacting. I'd permanently deleted a really big bunch of old emails in last few days, so probably a lot of space that could be recovered. I kept waiting and waiting and waiting, but without the progress I had no idea if TB was busy or possibly frozen. So I just left it alone. When I came back and tried to manually start compacting, it immediately said "Done, 0K saved". So it had obviously done the compacting.

If it's an option, how do I enable that progress bar? If not currently available, please consider restoring it in future TB updates. I -for one- think it's a very useful feature.

THX!
