When I launched Thunderbird today, it would not connect to one mailserver: imap.mailfence.com. At the same time, Thunderbird said to restart to update to 115.2.2. After updating, it still refuses to connect. There is nothing wrong with Mailfence and I do not find anything wrong with the configuration settings in Thunderbird. I even tried to set up my Mailfence email account again but it failed because it could not connect. Ideas? Thank you.

Our small business has a handful of Zoho email addresses that we use via Thunderbird on MacOS computers in our office. The computer I am using only has some of the email addresses listed in Thunderbird, and I am trying to add the rest.

Once all requested data is entered in the "Set Up Your Existing Mail Address" screen, we receive the error message: "Unable to log in at server. Probably wrong configuration, user name, or password." All of the data is correct, and I have tried this process different weeks to see if the issue will clear on its own, but no. I've attached a screenshot of the error message.

I have tried this with several pre-existing email addresses and it's giving me the same message, although it did allow me to add one address recently. That newly added, previously existing address is now somewhat accessible via Thunderbird, but every time we open Thunderbird it says "Login to server imap.zoho.com with username shipping@jadeandpearl.com failed." I can access the inbox and other folders of this account in the Thunderbird desktop app, but it is not currently showing new email.

Thunderbird version: 115.12.1 (64bit) MacOS: Sonoma 14.5

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.

This there a "Global" Message Filter Rule where you can change an Apply Filter When: to ALL your Message Filters?

Example: I'd like to add "Periodically, every 10 minutes" to ALL my current Message Filters. Currently, it looks like I have to Edit each and every one of them?

Thank you in advance.

I have over 35 email accounts, which I use Thunderbird to collect. Love Thunderbird for well over 2 decades!

I am wanting to have 2 of my email addresses to be downloaded before all the others. I have indeed successfully "moved" these 2 accounts to the top of my account list (Shift and mouse). However they are not downloaded in the order of the account list.

How do I accomplish this? Is it possible?

I created a ticket, and it auto-responded to run this by the Volunteer Community. I really want this to be handled by support, but welcome anyone to give me a solid answer.

While accessing my yahoo Mail account on the firefox browser for any length of time the Yahoo mail Will breakdown and completely lose all functions. While accessing my Wall Street Journal account on the firefox browser, I note that commentary on many articles is blocked. That is, the commentary section of the article shows no comments posted. However, when I switch to the Safari browser, the same article Will show multiple comments posted.

Thank you for your help!

For over a month now i have a problem with youtube. It loads videos very badly. I have good connection speed, but 0 network activity and 0 buffer health in Stats For Nerds on youtube and videos dont load. I can wait for 10-15 minutes (but sometimes they load almost instantly) before video load 40 sec buffer and after that buffer ends i can wait for another 10 minutes befor it load buffer again.

This problem persist only in my firefox on my computer. I tried deleting all the extensions, reinstalling firefox, "refresh firefox" future, changing useragent, reinstalling windows (it was the time anyways) but it doesnt solve the problem. I dont have this problem in other browsers (edge, librewolf, chrome) on my computer.

Right now I'm using 3 different email accounts on Thunderbird. All 3 of them are Office365 accounts. For some reason, 1 of the 3 accounts is prompted at least once a day, sometimes twice a day, to enter my password on the Office365 website popup that is used with the OAuth2 authentication process. It's very irritating, all 3 accounts are Microsoft Office business accounts. What would be the reason why it needs to authenticate daily? Is there no password manager to do this automatically once it's been entered once? Can I pick a different authentication method? What is the correct change to make so I don't have to keep typing in my password every day?

See the previous, now archive post about it.

If this option makes emails sent from Thunderbird to any other email client have arbitrary line breaks where the line changes in the view of the composer. Please explain to me like I am 5, why is this ON by default? I just spent hours wording and formatting a work email vital for my career just to find out it will most likely look like a poem to the person that reeds it. This mailnews.wraplength "feature" looks a lot like is there to signal to other non-Thunderbird users to use Thunderbird. I really really hope there is a good explanation for why `mailnews.wraplength` exists and is on by default.

When attempting to log into my website admin using Firefox, I am unable to view my saved passwords for all websites such as HVAC, contractors, painting, and golf. How can I resolve this issue?

If you're unable to see your saved passwords in Firefox for your websites, here are a few steps you can try to resolve the issue:

Check Firefox Settings:

Open Firefox and click on the menu button (three horizontal lines) in the top-right corner. Select "Preferences" (on macOS) or "Options" (on Windows/Linux). Go to the "Privacy & Security" panel. Scroll down to the "Logins and Passwords" section. Ensure that the "Remember logins and passwords for websites" option is checked. View Saved Passwords:

In the same "Logins and Passwords" section, click on "Saved Logins...". This will open a new window/tab with a list of all saved usernames and passwords. Clear Private Data:

Sometimes clearing your browsing history and cookies can resolve issues with saved passwords not appearing correctly. Go back to the Firefox menu, choose "Preferences" or "Options", then select "Privacy & Security". Scroll down to the "Cookies and Site Data" section and click on "Clear Data...". Make sure "Cookies and Site Data" and "Cached Web Content" are selected, then click "Clear". Update Firefox:

Ensure you are using the latest version of Firefox. Updates often include bug fixes and improvements that can resolve such issues. Check Password Manager Settings:

If you use a third-party password manager or Firefox's built-in password manager, make sure it's enabled and functioning correctly. Extensions/Add-ons:

Disable any extensions or add-ons that might interfere with password saving or autofill features. Reset Firefox Settings:

As a last resort, you can reset Firefox to its default settings. This will disable extensions and reset other settings. Go to the Firefox menu, choose "Help", and then "Troubleshooting Information". Click on "Refresh Firefox" to reset. If these steps don't resolve the issue, there may be a more specific problem with your Firefox profile or installation that could require more advanced troubleshooting.

"Unable to write the email to the mailbox. Make sure the fle system allows you write privileges, and you have enough disk space to copy the mailbox."

After years of working fine, this message has started appearing whenever TB tries to retrieve messages. I've checked that there's enough space (there's many GB free). I've checked the authorisations of the email folders, they're all fine (Full Control in all cases). I found an answer in a forum suggesting that a rogue antivirus might be the problem, but I'm only using MS Defender.

In desperation I removed the entire Roaming/Thunderbird folder, uninstalled TB, reinstalled it (version 115.12.2), created a new profile for my email address (it's a Yahoo email address, and I can retrieve the emails directly through the Yahoo Mail website with no problems). But I'm still getting the same error message. TB tries to retrieve the messages, it says 'Retrieving message 1 of 105' for several minutes, then the error message popup, and nothing appears in the Inbox. (105 is all the incoming messages as of now since this started happening).

I'm completely stuck. Any suggestions?

I back up my TB profile every few months. I just went thru the Cox-Yahoo email conversion and I am getting emails. When I did my back up, I noticed in the properties it had one more folder and the files went from 1311 to 2585 files. Is something wrong? Do I need to compare and research what is causing this or just move on!

Short background: Critically low on disc space. Windows pointed out a potentially extraneous 8.5gb NS3TMP Thunderbird file. Extensive Googling convinced me it would be safe to delete this file. To be safe (HA!) I first copied it to an external drive just in case things went south. They did.

After the copy, I went back and deleted the NS3TMP file. However, much to my horror, instead of deleting 8.5gb as expected, 30.5gb got deleted. After that, Thunderbird would not start claiming my profile was missing.

I copied the 8.5gb backup file back to its original place. No joy. Same message from Thunderbird.

At this point, I recreated my profile pointing Thunderbird to my Outlook email account.

I could now sign into Thunderbird and T'bird started populating the inbox and sent folders, but only partially. Worse (MUCH worse) my critical Thunderbird local folders were nowhere to be found. I attempted several folder recovery procedures to no avail.

I confess, I do not know how Thunderbird works its magic behind the scenes. Were my local folders part of the surprise 30gb file deletion and thus gone for good? Would the original emails that had been dragged into the various folders still be sitting on Outlook's servers?

As I said, totally self-inflicted but hopeful there's a road to recovery.

Any assistance or consoling words would be much appreciated.

I had my hp warranty service do everything you told me to do the Fire Fox browser is still the same the screns dont change & slide bar dont work right use to work good been doing this for 2 months your updates messed it up its your website crome works good please fix it

The default attribution line created by Thunderbird when replying doesn't work well when sending e-mail to Outlook users. [Unfortunately, Outlook users comprise 100% of the people to whom I send emails in TB.] TB's default attribution line causes Outlook OWA to hide the entire reply from the reader unless they click on a [...] button to show it. Then when displayed, the entire message is quoted/indented.

Yes, this is a bug in Outlook. No, it's not going to get fixed.

This can be avoided by changing the attribution line which current defaults to:

       On <date> <time>, <name> wrote:

Simply adding a space after the colon at the end of the line "fixes" the problem, but it's annoying to have to do that manually.

Can that attribution line be configured somewhere?

I've found all sorts of addons that let you muck with the headers of replies, but the headers are fine. It's just the attribution line that needs to be fixed.

how are shortcuts created on my "new tab" home page in firefox browser. I used to be able to create the shortcuts I wanted, not random shortcuts that I might have visited once. Now shortcuts appear that I don't want. I know I can remove them by dismissing them but I should not get them in the first place. Please help.

There is an issue with 3 extensions: 1. Briskine. 2. Simple Gmail notes. 3. Boomerang. This issue is taking place only when Briskine is active and only on Firefox.

When Briskine is active Simple Gmail notes does not display at all. Boomerang does not display correctly so there is no access to the full screen and options.

This only happens with Firefox, not with Chrome or Edge. Also, it is a know issue that's been going on for a while. I wish it could be fixed. Thank you Adam 747-256-2233 adamcornfeld@gmail.com
