I have 7 RSS Feeds installed and working.

The problem is that 5 of them only update when I right click and update manually but the first 2 update normally when I select "Get Messages".

I've checked each feed and they all seem correct in Properties.

Anyone out there have a suggestion or solution?

Any help will be greatly appreciated.

I'm in the process of cleaning up Thunderbird e-mail before moving to a new computer. I started with 11,593 e-mails in my Inbox and 7,799 e-mails in my Sent folder. I'm now down to 7,634 in my Inbox and 4,965 in my Sent folder. I've allocated 2 weeks for this process and found that it's taking me about 3 hours per day to meet my daily goals. I'm finding that I'm spending at LEAST half the time responding to "Empty-Trash/Compact-folders" requests. There are times I can delete 50 e-mails at a time without getting a request. Other times I will try to delete ten e-mails and get the request. With the old version of Thunderbird I could literally delete hundreds of e-mails at a time. Can you help? Russ Bukwa Yardley, PA ps. I have intentionally given you specific numbers. Based on my software- and test-engineering experience, I speculate you need to create a stress test to solve this nagging problem.

Hi,

Firefox version: 139.0.4 (64-bit) OS: Windows 11

I have been having issues where Firefox tab will just crash out for no reason it appears and it happens at random times and once the tab start to crash, and I restore it, it will crash again and again. The only way tog et out of the loop is to restart Firefox.

I have tried: Refreshing/Reset, Clearing Cache and History removing all themes, disabling extensions, disabling my anti virus. Turning off hardware acceleration didn't make any different.

I currently have 2 extensions enabled: uBlock Origin 1.64.0 and Bitwarden Password Manager 2025.5.0

In the about:Crashes I have reported them all and they seem to have the same type of reasons in the Raw data/Minidump which are: EXCEPTION_ACCESS_VIOLATION_WRITE EXCEPTION_ACCESS_VIOLATION_READ

Any help as to what to try next?

I have some websites that require pop-ups. I cannot get them to work in Firefox on my Android phone. Google searches reference a setting under "privacy and security" where I should be able to allow pop-ups in general or for certain URLs only, but I don't have that setting option.

I have Firefox version 139.4 if that helps.

Thanks in advance, Paul

I am using MacOS 10.13, Thunderbird 115.15.16ESR: my Hotmail worked until 15 May 2025 and then it would not download new emails. Screenshots are available if you want me to post them. I got an error message: "authentication failure while connecting to server outlook.office365.com". I updated Thunderbird to the latest for my OS: 115.18.0ESR. Still no new emails. I deleted my email account on Thunderbird and tried to reinstate it. Now I get an error message when trying to set up the account: "Unable to log in at server. Probably wrong configuration, username or password." I tested my password by logging into my Microsoft account with it on my browser. I can also login to my email using Firefox, but I want my Thunderbird email client to work again.

The configuration I am using is: I use my normal hotmail password in the password field. I also set up a new App Password with Microsoft and tried that without success. With the 115.18 update there is a new field: Your login. I just put my hotmail email address in here. incoming: outlook.office365.com, port 993, SSL/TLS, Oauth2 
outgoing: smtp.office365.com, port 587, STARTTLS, Oauth2 (I have also tried: smtp-mail.outlook.com)

I enabled 2-step authentication with Microsoft in my Microsoft account more than a year ago. Interestingly, I don't get a prompt on my iPhone Microsoft Authentication App when I select Done when trying to set up the hotmail account on Thunderbird.

Please help. I am desperate, and I have wasted a lot of time on this without success. Cheers

Hello,

I have not found an answer to my question anywhere, nor can I solve the problem I have encountered on my own. The thing is that when I log into my YouTube account and then close the browser, turn off the tablet, after restarting I have to go through the process of logging in to my YouTube account again. I think the browser is great. I am talking about the Firefox Focus browser. This problem does not occur on Firefox, but for my old hardware it is too slow.

Hello, I want to delete all incoming gmail messages. I have set up a filter but instead of deleting them it puts them in the Trash folder.

Is this the expected behaviour?

Hello,

Recently I have started to have emails fail to deliver to a certain domain and the message that comes back is

550 DKIM Sender Invalid - envelope rejected.

I am using Thunderbird v128.8.1 esr (64-bit). Extensions installed are: 1. Attachment Saver (Deimios, v.0.2.2) 2. FileLink provider for Send (Teal Dulcet v2.1.1) 3. Remove Duplicate Messages (Eyal Rozenberg v0.6.1)

I have been in communication with this client for several years and not had this problem before. When I send email to the same recipients using WebMail there is no problem, it is only when I send from Thunderbird.

I am not using any encryption type of setup.

Has anyone come across this before? Does anyone know of a solution?

Thanks, Franc.

Copied Thunderbird Profile on old computer to external HDD. Name assigned was zs6…. Installed TBird on new Win10 PC, omitting sign-in procedure. On this PC, clicked Menu, Help, Troubleshooting Info. Opened Profile folder on this PC, left-clicked Roaming, closed TBird. Copied zs6… from ext HDD, pasted onto TBird folder C:\users\owner\appdata\roaming on new PC. Clicked Yes to replace any existing files. Opened \roaming\thunderbird\profiles zs6…. not in there. TBird launches again in Setup. What am I doing wrong?

Hi, My Thunderbird email has stopped downloading emails from my server. I click to download emails, get a message saying "downloading 1 of 25" but no progression from here onwards. No messages are downloaded. I have made no changes to the settings and it has been working well for many years. wifi is connected.

Thank you for help to restore this.

I got a new PC with Windows 11. I installed Thunderbird 136.0.1 , activated the private calendar, and entered events there. For events with a reminder that have a specific duration (e.g., Wednesday from 10 AM to 11 AM), I receive notifications. However, when I create a full-day event and want to be reminded, for example, 1 day before, I don't receive any notification. Additionally, events with a reminder are not shown in bold in the calendar overview (whether they have a specific duration or are all-day events). Can you please help me?

YouTube videos encoded at 60 frames per second are extremely choppy in Firefox only. Microsoft Edge plays the same videos perfectly.

I have deleted my profile and reinstalled Firefox, updated graphics driver to the latest version, and toggled hardware acceleration on and off. Nothing helps.

I have the newest firebox version and i have you tube connected to the menu bar and 2 icons for it on the desktop i m not sure what if an addon are cause it to stay in full screen screen mode i do not wan it in full scene mode. i have done everything i know how to do to stop it from full screen please how do i get it ti default always just giving you a sample of what Iam getting just a sample of the size i do not have firefox zoomed it is on 100 percent and not zoomed the sixes is 16 and 14 an no larger.

Many of my mailboxes on the IMAP server just emptied. They were still there in my Ubuntu '.thunderbird' ImapMail directory. I have created some replacement mailboxes in 'Local Folders' and copied mbox files from the ImapMail area to the Local Folder area, removing the .msf files just created by Thunderbird. I then used the Properties->Repair Folder on each of the the new Local and filled-in-the-background mailboxes. Many worked fine and I was able to repopulate the IMAP server mailboxes using drag in Thunderbird. Some, however, were mis-parsed, producing 'From-less' and Subject-less messages containing part messages. Thunderbird seems unable to reliably parse mbox files created by itself. I note that they are not strict mbox format, having a '-' instead of an envelope address on the delimiting '^From ' line. (I am a retired Unix SysAdmin, so used to the command line)

Why the hell your history always been such a mess for android. Why that stupid grouping and no dates. And why tf I have to enter the search again in it after each opened link. You have no idea how annoying it is to look for anything. Surreal you can't figure it out in all these years

Tbird starts to d/l messages: "nn of mm new messages" counts up and just before it gets to the last few, it stops. It doesn't put the retrieved messages in the inbox or anything. Then it gives this error message:

"The DELE command did not succeed. Error marking a message as deleted. Mail server pop.mail.yahoo.com responded: Too many requests."

But this is POP mail, so delete request don't go back to the mail server. The number of emails deleted from the local db shouldn't have any effect on d/l... I'm mightily confused.

Yes, I did delete thousands of old emails. Still shouldn't make any difference for retrieving mail, nor should the client be overwhelmed by commands it successfully executed days ago.

Hi everyone I use Thunderbird Portable on an external SSD. I switch between a Windows 10 and a Windows 11 computer. On the Win11, I am experiencing some issues. When I run TB, sometimes the app "loses memory" and it opens as the first time, although the local folders seemingly should have all the emails (some folders have appropriate date and time, and the total size of the folder is OK). But I have no possibility to recover these emails. I tried to import them, but there always is some problem. I tried to copy all the folders in a previous (working) backup copy of TB, but still doesn't work.... how can I fix this?

Hello.

I use Firefox on an computer with Ubuntu, (installed as snap) and have noticed that since the update to version 140 (specifically, version 140.0 canonical-002-1.0), closing a tab causes a noticeable delay : that is, upon any action that would close a tab (clicking on the cross, pressing CTRL+w, or middle clicking), there is a delay of about 200 to 300 ms before the tab is actually closed.

However, during this delay, the window still responds to inputs, leading to rather annoying situations. For example, during regular usage, I usually open a great number of tabs. When I am done with browsing, I close them, by repeatedly clicking the cross button on the tabs. It used to be that the tab under the cursor would immediately close, then the next tab would slide under the cursor, and I would click again to close that one, etc.

But now, when clicking the cross button, the tab is not closed, and when I click again after a small delay (because of muscle memory), the tab is still there. This cause the two single clicks to be treated as a single double-click, which for some reason puts the window in full-screen mode (but only with the snap version; I'm not sure what's going on here).

When using CTRL+w when closing tabs, the delay is still there, but the inputs are correctly handled. If I press CTRL+w three times at the usual rate, I can see the three key presses, then nothing happens for a few instants, then the three tabs close at the same time (i.e. the delay is from input to tab close, not from tab close to other tab close).

This behaviour is completely absent on Firefox (also version 140) on my windows computer.

This delay does not appear when creating tabs, and it does not occur either when closing the window or when closing the last tab in the window (leading to an amusing situation where shutting down Firefox is actually faster then closing a tab). These operation keep going at their previous speed, immeasurably fast to the human eye.

Navigation does not appear to be meaningfully slower than before the update, and the CPU/memory usage is very reasonable.

Curiously, this appears to be a fixed delay. Closing an empty tab takes the same time as closing a very busy one. Closing a tab when there are five takes the same time as closing a tab when there are thirty.

This issue makes browsing feel incredibly sluggish.

Is there a solution for this problem ?

Edit 1 : I have tried to run Firefox in troubleshoot mode, but there was no difference in behaviour. Edit 2 : Fixed typo. Edit 3 : Added exact version. I also tried to refresh Firefox, but the issue remained. Edit 4 : The problem is still present in version 140.0.1 canonical-002-1.0. Edit 5 : The problem is still present in version 140.0.2 canonical-002-1.0.
