I'm running Thunderbird 140.3.1esr (64-bit) on Windows 11. Possibly because I was changing some settings, possibly because of a Thunderbird update, there are a couple of wonky things going on in my Folder Pane and elsewhere. Among them is the fact that one of my "Archives" folders now has a "Sent" icon instead of an "Archives" icon (see attached). Does anyone know how to fix this? I've tried the following: 1. Repairing the Thunderbird folder. 2. Restarting Thunderbird and my computer. 3. Installing the latest version of Thunderbird (without uninstalling though).

I posted this and was told it was ;posted, but then I got a not found error when I tried to view it, so I'm trying again.

I set a site to use firefox as the default app for ftp not realizing ftp support was removed from the browser. I have been trying to get the dialog back that will allow me to change it. I downloaded filezilla to use for ftp. However, I am unable to get the dialog back that will allow me to change apps.

Can someone help me get the dialog back? And, before anyone suggests it, resetting firerfox to the default settings is not an option.

Hello, When I open the window to write a new email the toolbar is missing. I can't see the buttons for "send" or "attach" or any other options.(you can see it on the picture) How can I restore the toolbar? Thank you for your help. Best regards, Bokor Vanessza

After the latest Thunderbird update, the line at the bottom of the displayed that Thunderbird was retrieving/downloading messages from my mail server is no longer displayed. I have looked for a way to display the activity but have have not found anything.

I would appreciate some assistance. Thank you.

It makes sense that you might want your signature text to change depending on who you are communicating with (employer, business, friend, etc).

In Outlook you can enter several signature texts, identified by a name. I sure would like to have that in Thunderbird!

Another possibility would be to circulate among several signature texts, just to "keep it fresh".

Thanks for your consideration.

Every time I open Firefox Nightly it opens Google Play Store to get me to rate the app.

This is a usability nightmare.

It asked me to rate the app originally and I pressed whatever the 'not just now' option was.

Now I get taken to the Google Play Store every time I launch Firefox Nightly. I cannot find any setting to revert this, and have no intention of leaving a review.

I am using Thunderbird and Firefox. Each are set as default on my MacBook. However, Thunderbird has recently started opening links in Safari instead of opening them in a new Firefox tab like it did just a couple of weeks ago. I cannot figure out how to make that stop. I've verified that Firefox is set as the default browser in my Mac's system settings. What caused this to change recently and how can I make it go back?

Running TB 128.14.0esr on Linux Mint MATE. In the Create new message (Write) window, I want to change the background colour of the panel that contains From, To, and Subject. This is currently a light grey. What userChrome code can I use to change the colour? Thanks

I have tried changing the font sizes in settings, but that doesn't seem to do anything to the font/size used to display the list of accounts and folders. I also tried changing Windows font size, and that does change the font size, but the bottom of each item is still truncated. I can't find a density setting in Thunderbird.

Thanks for any suggestions KR

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!)

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?

Good morning Is there a way to set up my own preferred default column layout to one that suits me I have 40+ folders and changing every one on new install and when updates are issued is a real pain I am on release 143.0.1 (64-bit) Many thanks John

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 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
