Hi,

I'd like to try to configure an Exchange (Office 365) account in Thunderbird Beta, and it doesn't work for me. I use the autodiscover and: 1. Thunderbird tells me that it can recover the connection settings, okay 2. It offers me IMAP, POP and Exchange/Office365. If I select the last one, it says that the server doesn't allow open protocols and that I must install/pay the Owl extension. 3. If I select "configure manually" with Exchange protocol, an error appears: "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsiMsgAccountManager.createIncomingServer]

Thx

This morning I saw that images were not downloading within my GMAIL messages. Believing that something was wrong with my connection, I decided to give both my computers a restart. This concerns my Windows 10 64-Bit, on which I had both Edge and Firefox opened, both with multi-tabs. In Firefox I had my Google account open with other tabs. After shutting down both computers I left my apartment. The Windows 10 restarted on its own; but both browsers lost their tabs even though I set each to reopen the previous session. With Edge and function keys I was able to restore my previous session; but not with Firefox. about:sessionrestore was not available. The Profile folder did not show a backup for these lost tabs. I hate hunting for them in History because I am working on multiple projects and don't have time for this wasteful activity, which is why I set Startup to Open Previous Windows And Tabs. What option did I miss?

Now, we have more wasted time. I reopened as many tabs as I remembered opened during the session I could not restore. Now, the only tabs that reopened since are the ones I opened that have posts about restoring sessions. The tabs I reopened are lost even though I checked off Open Previous Windows And Tabs. This browser is performing worse as of today for some reason I am not aware. What changed? From what I see here, there was no MS Windows update that might have occurred when I shut down and lost the tabs. Could I have disrupted the tabs by using the right hand, top corner "X" to shut out of Firefox?

This is getting more and more whacked up! It seems that every time I reopen a tab within the Library, it opens it in the same tab, overlaying the previous tab I opened.

Automatically hide taskbar in desktop mode => Enabled Firefox => Maximised When cursor is moved to outer edge of screen, taskbar should unhide (Expected behaviour) but in this case it remain hidden (Reality). Firefox along with all other spinoffs give same result. Chromium based browser works perfect, and taskbar automatically unhide itself.

As OLED screen have became common as monitor, Taskbar auto-hide is must. If this issue cann't be fixed I may have to change my primary browser which I used for almost 15 years.

Kindly, look into it. If Chromium can do it, why not Firefox.

Hello,

I am still having problems with Thunderbird crashing on startup

I first asked about this issue on the 2nd September, here: https://support.mozilla.org/en-US/questions/1461731

I have been submitting Crash reports per business day except for the last couple.

Here are the Submitted Crash ID's, I have been submitting reports as the crashes happen. :

Crash ID: ⁨bp-3b69ccf2-e3c1-431c-bada-e4f2e0240902⁩ Crash ID: ⁨bp-4c4852b8-6599-40b5-97b1-943930240902⁩ Crash ID: ⁨bp-09a86b67-a698-4c2e-a98f-e89f70240903⁩ Crash ID: ⁨bp-526167eb-c915-47fc-8065-f0b140240902⁩ Crash ID: ⁨bp-8965165b-c579-415d-9cb3-cdd010240903⁩ Crash ID: ⁨bp-a8aaf596-7dfc-43b5-8526-e204d0240902⁩ Crash ID: ⁨bp-b45149f4-8bb8-44df-84e4-b78fe0240902⁩ Crash ID: ⁨bp-c284df19-7d63-469a-af6c-9ff6c0240903⁩

More available if needed

Notably, I have 2 computers each with Thunderbird, each accessing the same account. I have no problem on the other computer. I am using no addons on the crashing computer. I have uninstalled and reinstalled the latest version, computer restarts - still crashing. I have checked my RAM. 16GB on board - Basic Graphics Processing - Intel Iris XE.

Any assistance would be appreciated.

Best

I have Thunderbird installed [via Flatpak](https://flathub.org/apps/org.mozilla.Thunderbird) and suddenly it's not recognizing the profile that contains the email accounts. When launching it is showing the welcome wizard instead.

The file system contains quite a few profiles though:

``` $ cd ~/.var/app/org.mozilla.Thunderbird/cache/thunderbird $ du -h --max-depth=1 6.8M ./i58nuv2e.default-release-1 813M ./r77u2ylw.default 6.7M ./w92uxxz8.default-release 0 ./jncleef4.default 6.5M ./fbs6wcvl.default-release 0 ./lz1kt9ot.default 6.9M ./tv1kaebo.default-release 0 ./7f6s4la8.default 839M . ```

but `about:profiles` shows only `tv1kaebo.default-release` and `7f6s4la8.default`.

I'm pretty sure that I didn't do anything but updating the Flatpak and I definitely didn't change any Thunderbird settings or anything in its data directories.

The correct profile is `r77u2ylw.default` (its directory size is 813M while the others are less than 7M).

Hence I'd like to know how can I make Thunderbird use that profile and avoid that issue happening again?

• • PS:** And what's the best way of cleaning up profiles, since I only need one profile anyway? The Thunderbird UI doesn't even recognise all of them, so would be deleting them sufficient?

My Android Firefox app suddenly changed the language for the menus. I now can't read the settings options. Can you describe how to change the menu back to English?

I'm trying to move Thunderbird to a new PC. Both PC's are running Windows 11. I've followed the instructions for locating my profile. According to "Troubleshooting Information" my profile is supposed to be located at "C:\Users\photo\AppData\Roaming\Thunderbird\Profiles\k6i7koof.default-release\Mail\Local Folders". When I click on the "Open Folder" button, I receive an error message that the folder does not exist. When I try navigating to the folder manually, I can not find a "Thunderbird" folder under "AppData\Roaming". I've selected "Show Hidden Files/Folders" under Windows Explorer. I know my profile exists because I can access a set of Local Folders when I'm in Thunderbird. I'd really like to move those folders over to my new PC. Any help to find the profile folder will be much appreciated.

I just started seeing this occur today. When I started Thunderbird, my main e-mail has the subject matter, date and time, but doesn't display the message. All my other e-mail identities are unaffected. All e-mails from previous dates are displayed properly. New messages today are displayed correctly. I tried to forward one of the messages to another address, and it came out blank. I tried starting it in Troubleshooting mode, but it made absolutely no difference. How do I view the messages?

Overnight lost almost 1300 unread emails. To my knowledge, did not delete them, they are not in Trash or Junk, even checked WIN recycle bin. Nothing. Any ideas, suggestions?

Hi,

I was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?

I a using version 115.14.0-1 in a Linux Manjaro.

To update the outlook to use OAUTH2, in the SMTP there are no OAUTH2 authentication option.

Thank you Paulo Breim

I have been using Thunderbird for years and am on 102.15.1, which works well. I want to skip the 115 updates and go directly to 128.2 esr. My email accounts are at hotmail.com and charter.net.

If I run the 128.2.0 esr file I downloaded from MajorGeeks, will it update the existing program or install a second version of Thunderbird?

Also, are there any known problems getting email from hotmail or charter/spectrum accounts that would make it a bad idea to do the upgrade?

Thanks for any help with these questions.

I've had trouble with this in the past where logging into Ring won't let me get past my user name/email address. I can hit enter, reload the page, try using tab but nothing works. Then for some unknown reason it will go forward to the password. But this time it just won't let me proceed no matter what I do, the continue option stays grayed out. I can sign on using Edge but I don't want to use Edge or even have a second browser open just so I can see my security camera. I want Firefox to work correctly.

In the Thunderbird calendar, I'm trying to create a repeating event that occurs on the fourth Wednesday from Sep 25, 2024 through Jan 22, 2025.

But each time I try to set it up, using Jan 22 as the end date, Thunderbird changes the end date to Jan 21 and so the last event does not get created. I've tried several times and this keeps happening.

What's going on?

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

As described in [question] I am unable to install addons in Thunderbird: when attempting to install an addon, either via the in-app browser or via a file, a pop-up window appears for which "Add" and "Cancel" buttons do nothing (there is no way to move or remove the window without killing the process).

I am opening this question as this problem still persists over a year and many versions later.
