Hi, I'm coming to you with a bit complicated problem. Please be patient with my long explaining.

My wife's parents have each their laptops. I had installed Thunderbird to them years a go. They never had a problem receiving their mails until last week. Now they can't receive emails but can send. On the other hand they can receive mails on their cellphones but not send (Android phones, not Thunderbird app). I have checked Thunderbirds setting on their laptops, everything was okay.

I have 4 laptops my own. I am going to give them numbers that you can follow me better. 1) asus (my daily personal pc) win 10 home. 2) Linux (my bussines pc) Mint 3 &4 ) Fresh windows 10 pro installed unused pc. Only Firefox and Thunderbird are installed as extra.

I load parents' mail account manually to Thunderbird on my pc 2, 3 and 4. Result is the same, I can send mails but cant receive. I have created another mail account for them (same provider), result was also same (for pc 2,3,4). I have an email account on same provider, I load my account, resul is the same (for pc 2,3,4). I tried my other email accounts from another provider, all of them works perfect (for pc 2,3,4). So, I thought that the problem was on provider side. I called them and explained the problem. They said that all is ok on their side and I should contact to Thunderbird support. The name of provider is "YouSee" from Denmark.

But....... As a last thing I add their email account manually to my laptop 1 Asus. Then I started to receive hundreds of emails from their account, so their account worked on pc1. Then I thougth, if I transfer my Thunderbird from my pc 1 to 3 or 4 then problem will be solved. But didn't. After I moved my Thunderbird from pc1 to pc3 and to pc 4 parents account and my account on same provider (YouSee) could not receive mails but could send. All my other accounts from different providers worked perfectly on pc 3 and 4 after moving.

In some way, something is disturbing communication between Thunderbird and provider YouSee on all 5 laptops. All Thunderbirds on 6 laptops have same last version. I checked firewalls, Thunderbird has been marked on all of them. I blocked windows defender and firewalls, didn't help. I also tried all possible imap, pop3, cofigurations of the provider. I installed older versions of Thunderbird and tried, didn't work either. It can't be windows updates because all Windows pc er up to date. Windows version can't be the problem because my pc1 and parents' laptops have same Win 10 Home. It can't be Thunderbird updates because pc1 has some update as the others.

Can anybody help me to understand the reason of the problem? An email account can't work properly on 5 laptops but work normaly on the 6th pc while all provider and Thunderbird configurations are completely the same? What should I try more?

Thank you all in advance. Peyman A.

On my new page, I have lots of pinned links to the pages I most frequent. I wish I could set the default for these links so when I click once, it opens in a new TAB automatically.

I know I can write click, but it seems like and easy setting to do this for any link!

Whenever I try to send a message, I get this "Send Message Error - Sending of the message failed. An error occurred while sending mail. The mail server responded: steveklein@shaw.ca sender rejected. Please verify that your email address is correct in your account settings and try again. We have talked with Shaw and they say it is not their problem. My wife (lindaklein@shaw.ca) has no problem. I can get my email and send if I got to Shaw's website, but obviously I don't want to do this all the time. I want to use Thunderbird.

Unable to send or receive emails, via several gmail accounts. Thunderbird 128.5.2esr (64-bit); Windows 11 Home, 23H2 Have used Thunderbird and Gmail together for over a decade - various glitches along the way, but nothing for which some solution was not found, at least up until now.

1) On Dec 31, 2024, received an error msg "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox." Thunderbird Inbox for that gmail account had grown bloated - in part because Message Filtering had stopped working (another issue...): moved / deleted a bunch of emails, and was able to receive new ones.

2) On Jan 1, 2025, ALL gmail accounts stopped receiving messages, initially with error of "Connection to server.pop.gmail was reset." As of today (Jan 4), all accounts are still non-functioning, but T'bird has given up even throwing up an error when attempting to retrieve messages. Attempting to Send a msg results in: "An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Cannot connect to SMTP server 172.253.113.109 (172.253.113.109:587), connect error 10060."

3) Running Nordvpn and Norton security suite. Have defeated both, to no avail. (With close / reopen T'bird; Reboot system thrown in for good measure.) Note: Have ran both of those apps, with Thunderbird, literally for years without any known problems due to the combination.

4) Confirmed that the Gmail / Thunderbird settings agreed with Gmail recommendations (and each other).

5) Removed permission for one of the accounts from google's site, hoping T'bird would prompt for new one: no go. Then TRIED to Remove the Thunderbird-stored Account Password for that account, but was stymied by a "Windows Security" dialog asking for an Account PIN: Do not recall ever creating such a beast for Thunderbird, and none of the possible stored Passwords proved acceptable. Also wonder why a Windows Security dialog is being tossed up from within T'bird.) (The dialog box offers up a "try another way" option, but that simply calls up a prompt for Username / Password: NO COMBINATION of those worked. Note that ALL such combos are stored in Bitwarden and eWallet, and work for those same accounts in other access situations.)

Obviously a frustrating situation. Am posting this in the hope that someone will be able to provide suggestions. In the meantime, have decided that it may be wise to look for alternative email solutions, although that is definitely a Non-Optimal approach: am a fan of Copernic Desktop Search, which only works with either Thunderbird or Outlook, and I have much preferred T'bird over the years.

Recently, whenever I go to a website that has some info/links/UI that should be locked to the bottom of the screen, it instead shows up and inch or so above the bottom. So I was part of the website on top, the a floating info bar, then a tiny amount of website at the bottom. I have included an image to show what I mean, but some websites have even bigger bars that cover more of the screen. When I scroll up and down the website this floating bar remains at the same location on the screen, just about an inch up from the bottom.

Is there a way to fix this?

Thanks to the help received here and in the Reddit group I've been able to transfer almost all of my old colour and layout tweaks to a new intallation of Firefox (v133) on a new PC (running Windows 10). There's one thing that I haven't succeeded with though: I'd like to change the colour of the text in a tab when that tab becomes the active one.

This is the coding I'm using to change the tab's background colour when it's selected:

1. TabsToolbar .tab-background[selected]{

background: white !important; }

This works perfectly. But when I tried adding the line

color: black !important;

It had no effect. I'd be grateful for any thoughts. Many thanks.

When compacting local folder in thunderbird I get error message ( The folder trash on local folders could not be compacted because writing to folder failed. Verify that you have enough disk space [which I do] ,and that you have write privileges to the file system, then try again.) and nothing will work on thunderbird afterward.

gmail via IMAP will no longer send or receive normally as of yesterday. No changes on my end.

Receive attempts - nothing happens Send attempts. This message: Sending of the message failed. Peer’s Certificate issuer is not recognized. The configuration related to smtp.gmail.com must be corrected.

The sent mail does not show in sent mailbox, but it does go through.

Thunderbird is in my list of 3rd party apps allowed access in Google account.

Hi;

I'm using a Protonmail alias. When I copy my Hide-my-alias address in Protonmail using the Copy icon, the popup says Alias copied to clipboard it doesn't paste. Not sure if this is a Proton or FF issue. Looks like it's mot being copied.

More info:

Using Firefox

I clicked on my new HideMyAddress alias address, clicked on my alias copy icon, says copied.

It won't paste into the address field of a new email. Clipboard History is enabled. I can paste any History entry but not the alias I copied using the copy link next to the alias link.

To copy it to clipboard, I have to :

Open all alias' Sign back into account Highlight the alias address, copy Then it will paste

Tested with Brave browser:

Logged into Proton.me Copied alias and pasted into new email To address, it works.

Thanks for any ideas.

So, I was going down a research rabbit hole on my phone (Firefox for Android 133.0.3), and wanted to transfer the tabs to my PC. Apparently, sending 259 tabs is not really an intended use case, as only 99 of those tabs transferred (tab sending wasn't batched either), and now I can't send any tabs from or to my phone. I just get the error "unable to send" on my phone, and tabs sent on any PC don't arrive either. I tried signing in and out on those devices, but nothing works.
