Most of my buttons have disappeared except the send button, which doesn't work. Online help is confusing or doesn't fix the problem. I'm ready to move to a different platform. Why is this so difficult?

I tried the Toolbar fixes in this forum and got the menu to show up, thank you. (Any menu in Compose mode had disappeared. Actually, both Firefox and Thunderbird icons on desktop and Taskbar had disappeared as well, and I had to reinstate shortcuts. This may or may not be pertinent.)

But when I try to add "Send" to the menu, using customize, the "Send" icon is nowhere to be found as an option, so I cannot add it to the Toolbar in Composition mode. "Send" is grayed out in all bold textmenus. If I use Ctrl-Enter, message does get sent. Using Windows 10, still. Perhaps this is an upgrade issue?

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.

When I press the middle button of mouse and move the mouse to the left (or right) firefox takes that as "back" button and moves to the previous page. This feature is really frustrating when using web based cad-programs that use that combination to move the view.

I have tried to disable all gestures from my firefox but can't get rid of this feature that is really awful.

I would really appreciate the possibility for simple operation without any functionalities like this.

Hi,

I used to scroll up in current message using Shift+Space, but it stopped working for a few days now. it's not mentionned in moving around TB, so I don't know if it was normal behaviour or a feature added by TB's arch maintainer.

So thunderbird mail has this system where old emails spread horizontally across the top of the screen in small icons and if you select and open an older email from the sidebar for the inbox and then want to return to the inbox, the only way I have found to return to the inbox is to click and hold the left arrow on that horizontal bar at the top with the email icons. This is too time consuming. Is there a faster way? Also, is that bar necessary? Why not just have a system that uses the sidebar that actually identifies the individual emails.

Windows 11 Pro 64bit. I actually want to customise the tool bar - right click on that, you get 'Customise Menu", which does nothing. All I'm trying to do is recover the layout I had before this update. Calendar is missing for example.

Hi folks, I'm a happy Thunderbird user since more than 20 years.

I just updated my TB to Version V.153.0.1esr.

Then I want to compose an eMail and suddenly I recognized the two Menus with File, Edit, View and Send.... Attach are gone.

Normally from the top to the buttom I see the following menu lines: 1. Write: (no subject).... 2. File Edit View... 3. Send........ and Attach at the end 4. From.. 5. To... 6. Subject 7. The line with Paragraph etc. 8. The area to put my email text in

The lines 2. and 3. are fully gone.

Can you please give an answer how to reactive the lines 2. und 3. during composing an eMail?

Whereas on the Thunderbird Desktop software, where each identity on an account can have their own outgoing SMTP server, the Thunderbird for Android app does not have this feature. Why?

I used the "Export to Mobile" feature and got stuck for quite while until i found this out. This help article also only mentions this as a fact, but no explanation or anything. Why is there such a feature discrepancy between these versions? Why is there no warning while exporting that this will be an issue? Will this feature ever be added?

I do not want Firefox to be my default browser, nor to I want it to start when the computer is started. I DO want it to use the same tabs & windows as the previous time I closed it.

But every time Firefox updates automatically, it resets those setting back to te default. How can I get it to keep those setting?

My Thunderbird does look strange, though it works alright. It annoys me, there are black-gray rectanguler spots left top and bottom. It dissapears when in full screen mode. It is not in any other program. I add a picture. Is there anybody who knows how to solve this. Thanks, Hans, Netherlands

Is there a way to change the default font color for replies in Thunderbird? Nothing I do works, and it is a real pain to have to manually change the color every time I reply to an email.

Thanks.

All of my emails are being marked as read immediately. I have that option turned off in settings on all devices. I am not using bit defender. This only started after I moved to a windows 11 computer. I only have one account. I have read the previous forum similar issues.

When a piece of text is drag-and-dropped onto FF, FF navigates to that text. So, when I am filling a form and accidentally drop the text outside a text field, FF navigates away from the page with the form I am trying to fill. I have been using FF for more than 10 years and never found this behavior to be useful. Only annoying and counter productive. If FF at least opened a new tab, I could close it and not lose the work done so far. But ideally there would be no navigation at all. Dropping a piece of text on a webpage should not trigger any navigation. I need a setting to disable that behavior completely. PLEASE!!! 🙏

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?

Hi,

I've just updated my Thunderbird for Windows to 151 and I got this nasty surprise (this is why I hate updates these days).

The message list in dark mode, in a table view, now has this awful pitch black background instead of the normal dark brown as it used to have. It looks OK in cards mode, but I don't like cards mode.

I certainly hope this is a bug and not by design. Can this be fixed, please? It looks terrible, it's hard to look at, like old Windows 10 dark mode or some high contrast accessibility mode.

Thank you!

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!
