I have lost the toolbar on the new messages page. The toolbar that allows you to change fonts, resize, bold, italics, underline, and more. I have looked for hours to find out how to restore this toolbar. Can anyone help me?

Firefox has always been my workhorse for my business, but after the last update, I can no longer open Firefox on more than one desktop on my Mac. Firefox requires me to designate either a specific desktop to open Firefox on--or to open it on all desktops. This doesn't work for me because on each desktop I open a different site on Firefox. I will no longer be using Firefox for work, and since I was using Firefox because of what I perceived were stronger security measures, I am very disappointed. I really wish software engineers would stop "innovating" and fixing things that are not broken.

I want to send messages I delete to a Trash folder on my laptop, rather than the Trash folder on the server. Is there some way to do this? I'm looking at:

Server Settings > Security Settings > When I delete a message

This only gives me the option save deleted messages somewhere on the server.

(I have given up all hope of convincing Thunderbird to download all my messages, but fixing the Trash problem will make the program at least useable, from my POV!)

is there a way to prevent HTTP Basic Authentication dialog from stealing focus in about:config? It can be really annoying if a site logs me out randomly while working in another tab. Chromium browsers does not do that

The "Threaded view" option doesn't work, or at least not in the way I expect it to.

I've attached two screenshots of the same conversation, once of thunderbird and once of proton mail. Proton does chain the email thread properly, but in thunderbird it's completely detached.

Email conversations get really painful without proper email chaning/threading, especially if a replyee's client doesn't attach a quote ("> ...") at the end.

I've recent moved to Linux and Thunderbird from Win/Outlook. I have a singifcant message base that I've successfully migrated to Thunderbird, most in bound email but witha chunck of outbound too. This all appears in Local Folders, with the outbpund stuff in Sent Item sub-folders.

Card View suits my well, however when I look at the Sent Items local folders, I always see the from address (i.e. me) rather than to "to" address. This is pretty useless, however I can't see any way to influence if it shopuld the from or to address in Card View with local folders. Am I missing something?

Card View within a 'normal' email account shows either to or from as you'd expect, and therfore works fine.

Thank you.

Firefox is the default browser and pinned to the taskbar. When clicked, Firefox automatically opens places an additional icon in the taskbar. Once Firefox opens, in the second icon, any new links open in tabs, which is my preference.

The first image is the pinned icon in the taskbar. When hovering it only displays Firefox. The second image is the additional icon, when hovering over this icon the active page thumbnail is displayed.

Prior versions of Firefox did not have this behavior on my Windows 11 desktop PC. I've tried various settings in about:config but cannot resolve this issue. Is there some reason two icons are now required in the taskbar when running Firefox?

Hello Supporters I'm using Thunderbird build 140.2.1esr. I cannot get it to minimise to the task bar. When I set it to not minimise to the system tray and minimise it, it pops up for <1 second in the task bar then drops down out of sight and reach. Does anyone know the reason for this, please? I recently had to re-build my win 11 (24H2) system and I think it's hapenned since then. I am used to it minimising to the task bar and prefer that. Regards Tony Pickering.

Even though I've never changed my settings aside from the first time I changed them to my preferred settings, for whatever reason, Firefox no longer opens links I tap on in external apps. I changed the settings to do it that way the very first time and it worked fine up until a little while ago. Now, the only way it opens a link in the external app when I tap on it, is if I tap and hold, and then choose that option in the pop-up menu. As I said, in the settings it IS set to open links in external apps, but it doesn't do it anymore.

Hi! I'm on a relatively new to me (refurb) desktop computer running Win 10 Pro (64 bit)* and Firefox 143.0.3.

In the past week both Firefox and Win 10 have updated. I don't know what happened, but now when I boot up or reboot, my computer opens to Edge. Yuck! Every single time I have to navigate to the Mozilla page and d/l FF exe file again, then reinstall Firefox! Once I do that, all is well again. I have all my bookmarks back, etc. It also keeps changing my "default to Firefox" while I'm using Firefox, so I have to keep telling settings that yes, I still want FF to be the default browser.

Why is it doing this? How do I stop it? Can you believe I've been using desktop computers 38 years now? LOL I finally can't keep up with it all any longer. I wish they'd stop trying to save us from ourselves.

Anyway, I know I can't delete Edge or uninstall it. How do I shove it back into the black hole it has lived in until now?

Thanks very much in advance for any help offered. :)

Hello people,

When I compose a message in my word programme (Softmaker or Libre), save it in Docx format and copy/paste it into Thunderbird to send it everything is double spaced and nothing I do in the "compose" menu can change that.

I have tried it with "Use Paragraph Format" checked and unchecked and it stays doule spaced and nothing I can find in previous threads seems to address this problem.

What am I missing?

Hi It isn't really a question, but it get to know and learn how to use Firefox efficiently before I converted from Safari to Firefox. I knew much more in Safari than in Firefox. Once I know more about Firefox, Firefox will be a default browser in my desktop,mac. Thanks Ted

For several months, I think, Thunderbird on my PC was failing to receive any of my emails that people, including myself, sent to my mailfence.com email address. The emails to my mailfence.com email address came into my *iphone* just fine; just not into Thunderbird, which is on my PC. They used to come in fine into my PC's Thunderbird app for the last few years.

Turns out, I THINK, the culprit was that I had *thought* I was clicking the old "Get Messages" button, but that button WASN'T EVEN AT THAT SPOT anymore! Instead, I was mistakenly clicking the "Mail" icon, thinking it was the "Get Messages" icon, or at least that it was serving the same purpose as the old Get Messages icon used to give me.

Somehow I just now saw a bunch of emails to my mailfence.com email address come into Thunderbird, from my recent various experiments. Not sure how I did that; maybe clicking the "Mail" icon does in fact serve as a "Get Messages" icon?

Get a load of the attached screengrab, and you'll see my confusion: (1) There is no longer a "Get Messages" button at the upper left. (2) AND, there's no File Edit View bar of tabs at the very top like there used to be! The File Home View you see in this screengrab is from the PAINT app, I believe. I realized this problem by looking up in Thunderbird Support how to get "Get Messages" back and saw a screengrab that had File Edit View, that I then realized I was missing.

Thanks for any help getting me back my File Edit View and my Get Messages button. If you see other problems in this figure please I'd appreciate your letting me know how to fix that, too!

Hello, I am in the Old fashion table view style and have conversations enabled, so that I can see which e-mails belong together. My question is: Is it also possible to scoll through the complete content of a conversation with one key press, preferably where the double content is replaced by ..; everything just like in gmail? At this moment you have to open alle e-mails one by one. I know you can get a view with the heads of the e-mails, but I want to read easily through the content. Thank you!!

I got this answer to my problem:

The Send bar has disappeared KAMI 30 sep. 2025 19:35:12 Hi, to customize the toolbar in Thunderbird: Right-click on an empty space next to the Search bar in the toolbar. Select Customize… (Toolbar) from the context menu. A window will appear showing all available buttons and the current toolbar layout. You can drag and drop buttons to add, remove, or rearrange them. When you’re done, click Done to save your changes. This is the quickest way to restore missing buttons like Send, Attach, or any other tools you use frequently.

Unfortunately, the bottons like Send and Attach are not available here in my application!
