In my list of Inbox Unified Folders (13 of them), one folder in particular (the second one) is sometimes there, then at some point later is gone. It's still in the 'All Folders' list, but not in the Unified folders list. If I kill TB and restart, then it's back. I have no idea what ops might cause it to vanish. Any idea what's causing it to vanish or what I can look at?

I opened Thunderbird this morning and there were no issues. Closed it and just now reopened and I'm getting this message: Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

It downloaded 28 emails but will not let me see/access them.

Can anyone help? Thanks, Linda

Hi, it has been a while that one of the updates on firefox removed the ability to navigate using the middle click, i waited and waited for some day an update drop and fix that but it's been a while and nothing has come, i was sure to test this on another computer and it didn't worked as well so i'm pretty sure firefox has some problems, i mainly use a drawing tablet because i don't have a mouse, so navigating is a bit hard without the usual middle click nagivation(i'm not sure if there is an actual name to that), please help

Hi, just upgrade to Windows1 and did a new installation from Thunderbird. latest version 115.11.0 (32-bits) But the new messages are almost directly market as read even with setting mark messages automatic as read set to no? On a other pc with Windows11 I had the same problem with the 64bit version but going to the 32bit version solved the problem. Any Idea how to solved this problem? Regards Karina

Every-time I open up Thunderbird e-mail Version 115.11.1 (64-bit) to access my Outlook E-mail Account, it pops open a box wanting me to enter my password! :-( I can enter it and mark that box to use "Password Manager", but it doesn't matter if I check that box or not, because every-time I reopen Thunderbird it asks me for that password again! :-( This problem just started in the last few weeks...... Once I enter my password, I can receive and send e-mails just fine, but when I close Thunderbird and reopen it, that popup box reappears again, where I must enter my password. (see picture I attached) If I just X out of it, I can't access my e-mail at all, as that box asking for a password, pops back open again asking me for my password AGAIN! Which by the way is 100% correct, as I can access my e-mail through Firefox, Google Chrome or Edge Browser just fine. I have used Thunderbird for years and have NEVER encountered this problem before, I hope you have a fix! I am running Windows 10 Pro Version 22H2. Thanks in advance! Keith

For months I was experiencing the problem of "Thunderbird not responding" occasionally. It was a short duration issue (a few seconds to a minute). I reinstalled Thunderbird several times without success. I read almost every comment available online about this problem and I tried many ideas and recommendations I found without success. Most recently the problem became so serious that it was not a nuisance any longer. It was nearly impossble to work waiting for minutes to open an email or to continue typing while preparing a message and being interrupted by the problem I am describing. I ran Thunderbird in safe mode and determined that none of the add-ons is causing the problem. I turned the firewall OFF and determined that firewall was not causing the problem. I then decided to run Thunderbird in Offline mode and found that the program works normally. Then while in Offline mode I decided to download more messages and the program asked me if I wanted to switch to the Online mode. I said yes. New emails were downloaded and without going back to the Offline mode I was able to work normally without any occurrence of the "Thunderbird not responding" problem. I have been using this workaround for several days now. I download a number of eamails. I try working in Online mode and I cannot do it. I switch to Offline and work fine. I switch back to Online mode and I don't see the problem any longer for the whole day. Do you have any idea as to the origin of my proble? I am running Thunderbird 115.10.2 64 bit on Windows 11. I had the problem originally using Lenovo T490s and more recenlt Lenovo X1 Yoga

Good afternoon I have 2 accounts in Thunderbird - a gmail and a Yahoo. Both were running great from the time I set up Thunderbird about 2 weeks ago until yesterday when the gmail account stopped sending and receiving. The Yahoo account is still fine. I have not received a message in Thunderbird in my gmail account since, although I have logged in on the web and confirmed that there are incoming messages in my account.

When I attempt to send a message from the gmail account I receive an error message - "Add Security Exception". If I click "View" nothing happens. If I click "Get Certificate" the section "Unknown Identity" changes to "No Information Available". However, when I cancelled the message I noticed a new error message appeared - "Send Error Message" and when I returned to the main Thunderbird screen I noticed a new tab appeared "Certificate for smtp.gmail.com".

As you can imagine, I seem to be getting nowhere with this and as I am only an intermediate user with computers I don't know where to go next. Subsequently, I sincerely hope that someone out there is able to help me. Any assistance would be very much appreciated.

The following are my Thunderbird settings for the gmail account :- Incoming Server Server type : IMAP Mail Server Server name : imap.gmail.com Port : 993 User name : [myname]@gmail.com Connection security : SSL/TLS Authentication method : OAuth2

Outgoing server Description : Google Mail Server name : smtp.gmail.com Port : 465 Connection security : SSL/TLS Authentication method : OAuth2 User name : [myname]@gmail.com

A copy of the error messages as well as the Certificate are attached.

Hello, Since a couple of weeks I'm facing a strange issue on my Firefox installed on my desktop (arch linux) where the suggestions window that appears when clicking the URL address bar, is shifted upwards and covers the address bar itself and the majority of the bookmarks. Has anyone experienced a similar issue and is able to point me towards some troubleshooting steps? Thanks!

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

I see that others have had the same problem as me. My trash folder has many thousands of duplicate emails. If I block delete them it will take days to complete. So 3 questions 1. How do I stop duplicate emails in my trash. After deleting many reappear with the date 01/01/1970 2. Is there a faster way of deleting. I use select email>shift key>find last email>delete 3. Is there a limit to how many emails I can put into the block mentioned in #2

Dear Support,

suddenly my INBOX file has a size of 480GB - the mails in all my IMAP folders online is less than 4GB.

How can that happen?

Is there a fix or should I just re-create the account?

Best wishes, Johannes

I want to move a lot of gmails to the Bin but keep them in local folders. An answer to someone else's problem said to be sure the local folder contains a true copy and not just a link, by checking that I could read it, but how do I do that for several thousand emails? Maybe they are all true copies in at least in one local folder? I need to remove a large chunk of 25000 gmails in All Mail to free up space on my hard disk. I was having problems with Global Search and followed instructions to re-index everything. Apart from taking several hours to index All Mail, I subsequently found that I could no longer get 2GB free space by using Disk Cleanup, the best I could get was about 300MB, which is apparently too small for Thunderbird to compact All Mail, or for Dropbox to sync with my mobile phone camera photos. The All Mail file in C:\Users\Michael\AppData\Roaming\Thunderbird\Profiles\hgwapwu4.default\ImapMail\imap.gmail.com\[Gmail].sbd is 4.5GB, and Important is 1GB

Here is a very strange problem: 1. all my notifications about interac are attributed to only one person: INTERAC e-Transfer: A money transfer from X has been automatically deposited. Under correspondents I have Y, no matter what X is. 2. When I do a global search for INTERAC, all notifications show up, but attributed to Z, different from X and Y. Further, Z only sent me an interac transfer once, maybe 10 years ago. Indeed, if I global search for Z, none of the interac notifications show up. 3. this is ONLY on Thunderbird, not at the server.

Any ideas?

I'm hoping someone can help with a conundrum.

A few years ago, whenever I first started Firefox--whether I had just started up my computer or had exited Firefox and opened it back up--it would take several minutes for Firefox to load any website (Google, Amazon, weather.com--anything). Once the first site loaded, it would load subsequent sites normally. Interestingly, it was only my default profile that was affected; if I used another profile or created a new one, websites would load within seconds of my starting Firefox.

I finally broke down and created a new default profile, imported my history/bookmarks/etc., reinstalled extensions, adjusted settings, etc. The new profile behaved nicely, loading the first website within a few seconds of Firefox starting. But over time, the load time has gradually increased to the point where it is now behaving just like the old profile: I load Firefox, I try to go to any website, and it takes several minutes for it to load.

Any ideas what's happening/what's the problem? Hoping someone out there has some wisdom and can help troubleshoot. Thanks!

I've read a few historic suggestions about how to resolve this, but I haven't been comfortable with what solutions were suggested as they didn't seem to comprehensively answer the questions, I'm afraid.

Until this morning's attempts to resolve the "running out of disk space" warnings, I had two mail accounts on Thunderbird - my old Hotmail account and my new personal domain based account. Both accounts had old emails (3/4 years' worth) filed locally on my PC pending my satisfaction that the new mail account was working satisfactorily. To try and resolve the storage issue, I deleted all the locally stored emails from my Hotmail account from within Thunderbird, then deleted the Hotmail account, and restarted both my PC and Thunderbird.

The expected reduction on space occupied by the .thunderbird folder didn't materialise - at all.

How can I get back the space so I can continue working, please?
