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 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

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?

I had 115.2.2 installed and all was good. I upgraded last night to 115.7 and things seemed ok but I am now on the road at Atlanta airport and I can neither send nor receive email. In the lower left corner of the display it alternately is stuck on compuserve: connected to imap.AOL.com or my other server eberger35:connected to imap.comcast.net

If I try to send a message from either my compserve/AOL, or comcast, or gmail accounts I get this error message:

The message could not be sent because the connection to outgoing server (SMTP) smtp.comcast.net timed out. Try again.

If I try to send from the compuserve or gmail accounts the message will reflect that server SMTP has failed instead.

I think everything was working at home before I left, but I'm not sure if I checked mail after I upgraded. Perhaps the problem is the Atlanta airport Wifi, but I won't be at my destination till much later today and thought I would post this now in case someone has an answer. I will be able to get the reply on my iPhone. Thank you.

My Firefox tab keeps crashing on a particular website. Whenever I go to twitch.tv, the site begins to load and then I get the "Gah. Your tab just crashed." screen. I'm only getting this crash on twitch.tv pages, and this issue just started on May 31, 2024. When I try to open a twitch.tv page in Private Mode, the page loads just fine. I've never had a Firefox tab crash prior to this.

I've tried turning off all of my Firefox extensions, but that didn't solve the issue. I also tried opening Firefox in Troubleshooting Mode, but I still got the tab crash. I'm using the latest version of Firefox as of today's date.

Good morning. I need help with sending emails in Thunderbird. The problem has existed for a couple of days now and is confusing as some emails are sent and others fail. I am receiving mail OK. Details of my setup are :- I am using a HP All-in-one desktop running Windows 11 with Norton 360. My Thunderbird account settings: Server type: IMAP mail server User name: ****@gmail.com Server name: imap.gmail.com Port: 993 Connection Security: SSL/TLS Authentication: OAuth2 Outgoing Server (SMTP): Google Mail – smtp.gmail.com (Default) User name: ****@gmail.com Port: 465 Connection Security: SSL/TLS Authentication: OAuth2

The problem: I only recently set up Thunderbird and at first it seemed to working OK. However, now when I try to send a message, after some time, I the following error message :-

"Send Error Message Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. Try again."

What is particularly confusing is that some messages are being sent. I have tried several fixes that I found from the Mozilla, Google and Norton web sites but none of the fixes resolved the issue. Any assistance would be very much appreciated.

Regards Mike

PS: I have 2 email accounts set up in Thunderbird. I just tried sending a test message from the Gmail account to the Bigpond account. From the Gmail account it appears to have been sent but in the Bigpond account an error message appeared as follows :-

"Could not connect to the mail server smtp.telstra.com; the connection was refused."

I don't know if this is a related issue or I have another one to resolve.

My phone has been deleting emails from my mozilla account and removing them from my laptop. Although I can still delete from my phone they don't delete from my laptop. This system has been working for years and I've only just noticed the problem. I normally use my phone for this so I have about 3 months worth of emails still on the laptop.

Since the latest update, when I right-click on a bookmark or an item in the history list (from the menu or the bookmarks toolbar), I still get the menu that has items like "Open in new tab" or "Edit Bookmark".

However, the focus for the mouse stays on the previous menu, so that I can't click on anything in the "right-click menu", instead it is interpreted as a click in some random item in the previous menu.

Going into troubleshoot mode didn't help, so I don't think it's my configuration causing this.
