Others have mentioned this but I'm not sure if there is a fix/anything is being done. The threads are all from previous Thunderbird versions.

I use Thunderbird for work. I have to find specific emails and folders - get to them quick. I am no longer able to do this. It's really distressing.

This is something really basic, that should be the default or else really easy to change.

I'm on a Windows machine and using Thunderbird 140.3.0esr. I've been using Thunderbird since 2003 and never had any problems. Now I'm panicking!

I have been using Firefox since I first started using computers, so for over fifteen years. Initially, I only used it on my PC, but for the past few years I have also been using it on my iPhone and iPad. Until now, I have been a very satisfied user, but for some time now I have been extremely dissatisfied with Mozilla and Firefox. I have been using Startpage as my search engine for many years and Firefox is set up that way on all my devices. But on Apple devices, every time I open the browser, Google is now set as the search engine again and I have to correct the setting every time. I find this patronising, inconsiderate and extremely rude. If this cannot be changed very quickly, Firefox will no longer be my default browser on any device. I would be very sorry to see that happen, but it really is not acceptable. Are you so short of money that you have to rip off your long-standing users? I would be very grateful for a reasonable and helpful response.

I have 1 computer that shows bars at the top and left side that I like. The one at the top shows Get messages, Delete, Reply, Reply All, and a few more items. The one on the left side shows icons that are for Mail, Address Book, Calendar, Tasks, and Chat. I have another computer that doesn't have those bars. I have attached a screen shot from that computer. Both are running T'bird 140.4.0esr (64-bit) and both are Win 11 machines. I've tried everything I can see to get the 2 bars to appear on the 2nd computer. I hope someone can tell me how to get them to show up. Thanks, Mike

I want nothing to do with AI.

I have unticked perplexity.ai in preferences#search but every search from the search bar and address bar goes to perplexity.ai then immediately crashes and displays "Internal Error".

To use DDG I have to type duckduckgo.com on the address bar then search from there.

Firefox 140.4.0 ESR.

I've' scanned the PC with malwarebytes. I restored windows from a backup image I haven't made any changes to the PC at all. Was working fine in the AM but by later afternoon, it started using perplexity.ai exclusively.

How do I get rid of perplexity.ai

I use Thunderbird for my emails on a Windows-Desktop. I still run Windows 10 as the computer is too old to upgrade to Windows 11 and I have signed up for the extended Maintenance.

In Thunderbird I have set up filters to organize my mail. When I wanted to change one of my filters a few days ago, I was not able to do so, as my Menu in Thunderbird doesn't show the ->Extra Option any longer. My Thunderbird-Version is up to date (140.4.0esr (32-Bit))

Any idea, how I can access my filters and maintain them again?

Thanks for your thoughts and your support

I recently transferred my Thunderbird email to a new Windows 11 laptop. Everything is ok, except the font size in received emails can best be described as very tiny. I've tried everything to increase the font size, but nothing helps. My screen has a resolution of 2880x 1880 Any help would be much appreciated. Thanks.

I'm trying to stop Firefox from restoring tabs after I restart my OS. So far, I've done the following:

• Disabled `Startup > Open Previous Windows and Tabs`
• Disabled all extensions
• Confirmed I do not have a `user.js` file
• Set `browser.sessionstore.resume_from_crash` to `false`
• Set `browser.sessionstore.restore_on_demand` to `false`
• Set `browser.sessionstore.resuming_after_os_restart` to `false` (It was already set this way.)
• Set `browser.sessionstore.max_resumed_crashes` to `0`
• Set `privacy.clearOnShutdown.openWindows` to `true`
• Set `browser.sessionstore.max_tabs_undo` to `0`
• Set `browser.sessionstore.max_windows_undo` to `0`

(I've since reverted the last two and the extension changes after they didn't work.)

So far, Firefox will not restore tabs on application restart (manually closing and relaunching) or on crashing (after sending SIGTERM/SIGKILL), but it still restores tabs after restarting the OS (if I allow the OS to kill it during shutdown). I've seen a couple suggestions to disable history completely, but I do occasionally refer to my browsing history, so I'd prefer a less-drastic approach. Ideally, I just want Firefox to treat the first launch after a shutdown as a normal launch and not apply any special behavior. Any help would be much appreciated!

For some reason on the app it switches between two layouts for my gmail account. From the photos I attached a drop down menu that says gmail is present in one of them but sometimes when I go to open the app sometimes it will just show it fully with out the gmail part.

If its possible I would like it to now show the gmail drop down menu.

Hello, i work for a Company that recently switched our eMail hosting to BoxMail and this company doesn't have an Android App.

After trying different eMail Client App i selected Thunderbird, BUT THERE IS ONE ISSUE

My BoxMail inbox is divided in a series of Sub-Inboxes where the eMails from Workers of the Company get automatically sorted into.

Thunderbird recognizes and lists these inboxes, in fact it lists them under the inbox

BUT IT DOESN'T INDICATE ME WHERE THE EMAILS HAVE GONE TO to be specific, i get notified when an eMail arrives, and it says in the little Bubble that i have... 36 eMails

But then, in my inbox i have only 7, yet all the SubInboxes still Display ZERO.

I have to enter each Sub-Inbox, and Refresh the Page to show me if there are new messages, and only after i do that, it will display how many unread eMails i have in that Sub-Inbox.

This is overly frustrating and time consuming, because every time i receive an eMail and get notified about it, i have to manually enter each of the 30 Sub-Inboxes i have and Refresh it hoping to find the new eMail Received.

Is there a way to set the Sub-inboxes to Auto-Refresh the eMails within every 10~15 minutes?

Because as it stands, i am losing too much time every day and eventually this will cause an issue that will force me to seek for a different App, and i truly like Thunderbird.

Thank you for your time is helping me solve this matter HAVE A GREAT DAY

Hi, lot of years ago I have changed TB to use maildir ibstead of mbox for new accounts, Now I met some filtering issue I can't fix and it is proabely caused by maildir.

So I'd like to set TB to use mbox with new accounts instead of maildir.

Some additional info: TB 144.0.1 (64 bit), win 10 pro, I have 4 mbox accounts and one maildir account.

There is no need to export / import / keep data existing on maildir account. I can remove it with no pain. I just want to setup TB to create new accounts as mbox again.

Any help will be appreciated.

TIA

Is there a way to make the “Today” tile stand out more clearly in the calendar month view? The currently selected day is displayed with a light gray background and stands out, but the actual day is only modestly marked by the day number. With many entries in the calendar, it is therefore difficult to recognize. I would therefore like to see a user-selectable background for the current day.

I am running Windows 11 with Thunderbird V144 and the Windows Classic theme. I find the background colors of the Message List Pane and the Message Pane almost the same as background of the Header pane. I would like to change the background color of the Header Pane so that it stands out more. I looked on the internet and found some solutions to most other Header Pane features but not the background color. Most of those solutions were additions to the userChrome.css file that appear not to work on V144.

I would appreciate some help with this.

When I read a message, the subject line font is larger than the other headers. Is there a way to make it smaller?

thunderbird email program does not have a "go to inbox" option. The program automatically creates tabs, and sometimes I need them. If so, it takes up to a minute to press the back button to go back all the way through them to the inbox tab. Why cannot mozilla thunderbird supply a go to inbox tab so I can go back to the inbox directly?

I don't really need to talk to a "volunteer". This is a question for whoever writes or engineers the thunderbird product. We should be able to send such questions and requests to those people who write and design this product. Does any "volunteer" know how to contact the needed personnel to redesign the product so it offers what I need?

I’ve set up Kagi as my default search engine on Firefox for iOS, but every time I open the app, it seems to revert the default search engine to DuckDuckGo. Then I have to set Kagi as default again. It’s a very strange bug. I’m not sure if it only happens when you set a custom search engine as the default.
