Is there a spam file for thunderbird? I haven’t been able to find one. Xfinity has a spam box on my site. I had mail sent to me and could not find them on thunderbird or Mac mail but I Katerina found them in the xfinity spam folder..

Each time I open Thunderbird, it redownloads 423 gmail messages. When I exit, and relaunch, it repeats this. I also get an error message. It's been doing this for a week or so, but never up till then.

I've checked my settings, redone the saved password so it's now Oath2 and am out of ideas.

Can you help?

Hi,

since MS has updated Win11 lately, my Outlook became a disaster. Therefore, I installed Thunderbird to become my new app for e-mails, calendar etc.. Unfortunately I can't find a way to import my Outlook tasks to Thunderbird. Is there a brief information or could someone give me any support in this matter? That would be very kind.

Thank you in advance.

Best regards ka

I have an issue in that, upon pressing the three-dot menu button on mobile, the browser menu is suddenly popping up from the bottom of the screen instead of sliding in from the side like it's supposed to, as well as what used to be a nice and neat list of options now being a cluster of hard-to-make-out icons and buttons. I didn't change anything in the settings to make it do this (I very specifically selected the "top" display option when I first downloaded Firefox months ago and haven't touched it since), and I've already checked reddit to see if anyone else is having this problem and if so, how to return my menu's behavior and appearance to normal (no luck).

I unfortunately have no images of what my menu is supposed to look like as it never occurred to me something like this could happen, but I can at least provide a screenshot of the ugly way it looks now (notice the little bar at the top of it that suggests I'd be able to "drag" it back to its correct placement? Yeah, it doesn't do anything, no matter how long I hold my finger on it.) PLEASE tell me what can be done to undo this awful change and return my menu to normal!

I've recently set up Thunderbird on Linux Mint 22.2 and was unable to sign into Yahoo so I tried to sign in with Firefox instead and had the same errors :-

   Something went wrong
   We could not sign you in. Try again from a different device.

OR

   We couldn’t sign you in
   Change your browser settings to continue. Try the following:
   Turn off ad blockers
   Enable JavaScript

If you still can’t sign in, try a different device.

I can sign in with Chrome without any problems on the same workstation. Firefox version :- 147.0.4 (64-bit)

   Only Extension is Privacy Badger, but this is disabled for Yahoo.com

Thunderbird version :- 148.0 (64-bit)

   No extensions - as installed from Thunderbird download site

I'm not having any issues signing into any other websites / email accounts (Google, Hotmail).

I notice on the support website :- https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo it says "Starting with version 148, Thunderbird is switching to a more secure authorization protocol PKCE for Yahoo" BUT this isn't offered in the list of Authentication methods, has PKCE been delayed? Currently using OAuth2 for Thunderbird

It is VERY annoying to me that all of the recent (since December 2025) automatic Firefox upgrades have deleted my previous session tabs, with no "Restore previous session" option offered. Prior to December, every Firefox upgrade was transparent with no effect on my open tabs. This new behavior annoys me so much that I'm likely to switch to another browser if there isn't a solution to stop this from happening. Please tell me how to avoid this problem, or consider fixing it in the next upgrade.

Translation: My emails in Thunderbird suddenly disappeared.

They were over 10,000, but now they're down to only 7,800.

Why?

I am not sure if this is a setting / UI issue in Firefox for Android or if it is a UI thing for Android in general.

I am using an Acer tablet with Firefox for Android. Before, I would use the three vertical dots icon to get the menu to display on the right of the screen (for example, when I need to search for text or look through the browser history). Now it is suddenly appearing in the middle of the screen instead and I can't work out how to put it back. I tried dragging it to the side, and double tapping on it, and looking through the settings. I searched online, but all I got was stuff about moving the address bar to the top/bottom or tips on menu design.

When I tried to import my OpenGPG keys from the "Select File to Import...", I found that it cannot display the hidden files or directories.

Did I miss a setting for this? What can I do to show the hidden files?

Would appreciate your help in advising how I can re-instate my Protonmail login as it just doesn't seem to want to let me access the site at all - it just tries to access and then keeps coming up with 'oops something went wrong'. It's like there is a block on letting me access? This has only just happened since doing firefox updates.

Cheers

I am trying to add a business gmail account to my Thunderbird on Desktop and have run into difficulty.

I tried to use This Article in order to overcome the issue, however it is dated 2018 and seems very out of date with the current UI. So I am struggling with how to rename the incoming/outgoing servers to allow the new gmail account into the host.

When I try to add the gmail account I get the window to sign into the new account, but when I click continue I get "The server cannot process the request because it is malformed. It should not be retried. That’s all we know." (see attached image).

Escaping out of the log in screen brings me back to the config page which appears to have accepted the account, until I hit continue and then it tells me that the incoming server is already in use. (see the second image).

I also tried turning off the experimental add account and use the previous interface to work the problem. I got the same results both times.

Please advise, I'd really like to have access to the account emails on my desktop without using the google web interface.

Thank you DD Randall

In trying to resolve an issue with email apparently not connecting (receiving new message and sending messages) I used the Troubleshooting Information option and selected the "Clear startup cache" option which resulted in mail disappearing but leaving calendar and contacts intact.

I've attempted to Import the profile backup to restore mail but it has not restored the mail.

I have also tried to re-add the mail account but it stalls at the Oauth stage with what appears to be some sort of dialogue box graphic trying to to open but not opening so am unable to add mail account back that way.

'Login to server mail.btinternet.com with username cmby2@btinternet.com failed.' This dialog box appears when Thunderbird is opened, we cannot remember our password as it has not been required before, can you help with this please? P We are tech dummies...

Login to server mail.btinternet.com with username xxxxxxxxxx@btinternet.com failed.

This is the message that keeps appearing

I have a new laptop with windows 11 (previously had a computer with windows 10) I got Thurderbird onto my new laptop however when I try to get in emails it keeps asking me for a new password. I keep entering the password for my provider but it does not remember it or does not accept itl It says its trying to connect to server but never does. then after a while it says it timed out. Is there another password I should be using?
