Hello,

My client has a specific problem with Thunderbird, when he does something with mail for example moving it to a certain folder or deleting one, all emails disappear, then when he restart the app all emails show up again and that mail is not deleted/moved, I tried all of the suggestions in the attachment and problem sometimes disappear for 1-2hrs but always occurs again. Also Thunderbird generated 50+ Inbox folders by itself and it keeps making them all alone. I assume the problem is with some corrupted file but his thunderbird backup is about 50GB and he needs it all to be imported. It really drives me crazy.

Thank you in advance for your support, Hope we will solve this issue.

After the most recent update of FF on Mac OS Sequoia, suddenly I am no longer able to login to either of my routers, because they require http and FF keeps forcing https.

This results in no login gui but instead an ‘unable to connect’ error message.

I have researched and tried every conceivable fix and nothing works (settings, about:config, cookies, cache, all of it.

I would have expected that simply adding exceptions in settings would work, but it simply doesn’t.

I can login via Safari, so this is clearly a FF issue. It even happens in Safe Mode.

Kind of at my wits end. Anyone have a fix.

Noticed earlier today that after a Firefox update two icons appeared on the taskbar. Now I'm finding that whenever I try open Firefox from the taskbar it doesn't remember my previous session and looks as if I've signed out, Firefox behaves normally if I launch from the start menu.

I'm using Firefox Browser Windows MSIX package, mozzilla-MSIX - 1.0 v1.3.1.0 (64-bit). On Windows 11 Pro v23H2 build 22631.4169.

after the changes in firefox 131 the following pref no longer hides tab manager:

user_pref("browser.tabs.tabmanager.enabled", false);

To further clarify, tab manager is the arrow button (or the new icon in firefox 131) besides the minimize button of your firefox window. I want to hide that.

Hello,

I have a limit of 1500 emails to receive, and it always deletes up to that number of emails the next day.

Please do something about it, because I set it in the settings so that it doesn't delete

I want to change settings in Thunderbird. Vivaldi 6.9.3447.51 (Stable channel) (64-bit) Revision 182bbf0e4fdf8cd7876d2b24819fde3147f9af97 OS Windows 10 Version 22H2 (Build 19045.4894)

I tried all the other options in drop down menus all over and they all come up. But clicking on settings does nothing. I even went into account settings and tried clicking on Thunderbird Settings and it does nothing there also. Can I reinstall over the existing program without losing anything to try and see if that helps and fixes the problem?

Trying to install Firefox on my IPhone SE, 16,6. Get the message "cannot install because of limitations in settings for this unit". Which settings need to be changed?

You can help by going back to the old format. The new format makes it more time-consuming to delete unneeded messages because the screen shows only a small number of messages at a time. Also, the smaller print is less user-friendly.

I tried changing the authentication method to OAUTH2 for my Outlook live mail account (POP). For that, I had to change the server name to office365.com. After restarting Thunderbird, I was able to download new messages but all the old messages already stored in Thunderbird disappeared, even though Thunderbird still shows the same old Local Directory as being used.

How do I change the authentication to OAUTH2 & get my old messages back?

If I delete & again create the Outlook live account, would it effect my old mails/filters ?

I have Thunderbird V115.15 in Windows 7. Last week it stopped working correctly. Now if it starts a download from gmail it fails saying the account is being accessed by something else (but it isn't). Then when it does try to download the messages I either get 3 to 10 copies of every message or every message is blank and from a blank sender. Right now it is reporting 542 messages being downloaded but all are empty with no from info and those messages are from a week ago.

I am pulling my hair out trying to get this back to functioning!

Thank you

Hi - after a Firefox update today, I no longer seem to be able to access a sign-in page for any of my Google accounts. When I try to log into Google, I'm just brought to a page that says "clear cache and cookies." I've cleared my cache multiple times, restarted Firefox, run troubleshoot mode, restarted my computer - none of this has helped. Every time I try to go to a page to sign into any Google app - Drive, Gmail, etc. - I get taken to the same "Google Help Center" page telling me to clear cache and cookies. When I click on the "sign in" button in the corner of this page, it just brings me back to the same help page.

My Google accounts aren't the problem because I can access them from Chrome or Safari. But I don't want to use Chrome or Safari!

I've never encountered anything like this before. Help?

I am maxing out my Comcast email space allowance (10 gb) and want to move it all to my PC. (i don’t want an encrypted backup, but something readable.) I thought I could use Thunderbird and set up a POP3 account on Thunderbird with the option to leave emails on the server. It downloaded only the Inbox, not the subfolders. I read on the Forum that that is what happens with POP3. My understanding of IMAP is that I don’t get the actual email on Thunderbird, because it stays on the Comcast server.

Is there a way to download all those emails and folders to Thundebird (to keep) and then delete them from Comcast? I don’t plan to use the Thunderbird client for my day-to-day email, simply to store the last 10 years of email.

I have tried to research the forum articles so that I don’t bother anyone needlessly, but can’t find an answer. Thank you.

TB latest version on MacOS latest version TB has option to mark messages as read if it determines them to be junk this does NOT work. It puts them in junk folder but keeps them as unread. very inconvenient... any solutions? thanks (attached)

Hi,

I have a Mac with Sonoma. Somehow a while ago I ended up with Firefox ESR, which I was told that will not be supported after September.

I am a non-technical user. While I do have Safari and Chrome, I would prefer to continue using Firefox.

Could you please let me know the steps to execute to somehow switch from the ESR version to the current normal version without loosing settings, bookmarks or ending up with problems? Thanks in advance.

Is it normal that Firefox is trying to load the dll related to the Windows Credential Manager (vaultcli.dll)

"firefox.exe loaded module vaultcli.dll"

If so, what's the purpose of this interaction?

From the looks of it, Firefox is trying to access locally stored credentials using the Credentials Management API.
