Thunderbird 148.0 moved trash folder from top group in folders pane to alphabetical order in lower group. Reopening Thunbird didn't help. How to get it back into place? Thanks!

I am trying to enter my Thunderbird account to review my emails, however, everytime I click on the Thunder bird icon nothing happens. Please help me to regain my ability to open Thunderbird. I am falling wat behind in my work.

re: OAuth2 Authentication for Yahoo, AOL and ATT

My settings selections don't really follow your help descriptions to the letter,so..., also, I already have 2 accounts on 2 platforms and they seem to already be configured with SMTP outging servers using OAuth2.

I'm confused since I'm now on 140.8.0 and have not needed to change a thing, contrary to expectations set from T-bird app popup warning and Mozilla article.(?)

Running Thunderbird 140.8.0esr 64bit Windows 11 Home, v25H2 932GB storage 32GB ram i7-13700k

Recently, I've started getting the following message every time I launch Thunderbird: "The certificate for imap.googlemail.com does not come from a trusted source."

Digging into details I get: "you are about to override how Thunderbird identifies this site" "Location: imap.googlemail.com:993" "This site attempts to identify itself with invalid information" "Unknown Identity. The certificate is not trusted because it hasn't been verified as issued by a trusted authority using a secure signature."

Digging deeper into the certificate I find the issuer is Bitdefender who I use for antivirus and VPN. However, the VPN shows no effect when enabled or disabled. The validity period is 2 Feb 2026 to 27 Apr 2026

l can get email, but cant send it. Is Bitdefender at fault?

I'm stumped. What should I do???

Deleted around 400 unread emails at one time, something not done before. Thunderbird shut down, now can not log in. Do not have backup password or two step authorization. Any hope for getting back in?

Dears since yesterday i cannot download yahoo mails to thunderbird on my windows computer. when thunderbird gets new messages, a window pops up asking me for yahoo account name and password. when entered yahoo gives the following message: " Something went wrong. We could not sign you in. Try again from a different device." i use thunderbird 148.0 on windows 11 (out of china, with Astrill VPN - all other websites work normally with VPN). i have three different yahoo accounts, the first time thunderbird asked yahoo first mail and authentification went through, but it does not go through for the remaining two accounts. i verified that OAuth2 is set up for all accounts. password is correct (as i can still receive emails on iphone mail app). cookies can be accepted without any exceptions, can see the whole OAuth2 dialog panel. i did all steps for setting multiple accounts. i verified all accounts for POP and STMP server settings. also mailnews.oauth.usePrivateBrowser set to TRUE. After all this, it still does not work (i also restarted thunderbird and the computer), what else can i do? Regards Violaine

I tried to transfer Thunderbird file from old computer to new computer but get "Profile cannot be loaded. It may be missing or inaccessable." when I start Thunderbird. The old TB file works on old computer and I am pretty sure I copied it and pasted it into the new location in place of the current Thunderbird file.

As stated above, received msg from me to me -- a common practice I hear. If I change my password, will that fix this? I tried to log in to Outlook on line to change password but I use a passkey - doesn't let me do a password entry. Help..... Thanks.

I’m using Thunderbird 148, IMAP, and my folder pane folder mode is set to All Folders. I seem to remember Thunderbird showed me a quota bar so I would know how much space was left on the server. Recently no quota bar has been visible, what gives?

POP3 account. Trash contains folders that, mostly, I have no idea where they came from, and nothing I do will delete them. More than 30 folders at current count, all empty.

Anyone have any insight? Thanks. Brett

I never had this problem and only been experiencing it recently.

After turning my computer off, turning back on and loading up Thunerbird, my calendars are not displaying again. I have to keep removing and readding again.

I am using Google Calendar that is linked to my phone and pc. The phone is fine and always displayings my appointments. I am using the "Provider for Google Calendar" extension on Thunderbird.

I at first though it could be OneDrive interfering with the data, but that does not make much sense as its a calendar hosted on Google, but still I configured and checked the OneDrive.

I am at a loss and getting fed up of having to readd my calendars back every day. So, I don't know if this was an update that did it, a broken extension, etc. But, I am desperate for a solution.

Regards

I seem to have purchased "Owl for Thunderbird," unwittingly paying 10 Euros ($11.93) while in England on 2.11.26. I don't want or need it and I want remove and cancel the add on. I also want to stop paying. How do I do that? Where is it hidden in Thunderbird?

The calendar has a way for you to see all calendar events. Is there anyway to view all calendar tasks? My goal is to clean up the calendar by removing old tasks.

Updated to 148.0 this morning and now none of my google calendars are population the calendar. I am clueless as to why. Tried deleting them and re-adding them in - Not working. If this can't be fixed I am done with Thunderbird. Kind of sick of everything breaking with updates with no warnings.
