I updated, then I un-installed, then re-installed Ver 136, but still no confirmation request. after shift -delete. Highlighted Messages were immediately deleted with no confirm message displayed. What do I do to reinstate the "confirmation required" prompt?

During my messing around while trying to solve a UI problem arising from a migration to a new-to-me used Mac, I found a way to change the font size in the "Subject" field of e-mails in their own window, and as an experiment made it larger. It did not change the other problem, which has been solved.

Now I can't re-find that place in any of the settings, and want to change it back to the default. Please, someone, anyone, where is it?

Hi: I've just recently installed 135.0.1 Mozilla Browser and have found that the file SAVING-function in the 'Application Menu' does NOT PROPERLY WORK: it records my message-title but NOT the contents (0-bytes!) -I never had such a basic issue in many years of very satisfactory Browser-use ...am I have a wrong setting somewhere and is there any quick fix please ...? - Email me when someone answers the thread ...MANY THANKS, Tony H.

P.S.: Please send me a link where I'd get a help since I'm NOT GETTING ANY HELP FOR SEVERAL WEEKS ...! Thanks-Tony H.

I use Thunderbird on two user IDs on the same Mac, which is running macOS 15.3.1.

I usually run Thunderbird updates on user 1, but this time I ran the it (to 128.7.0esr) on account 2, and I can no longer launch it on user 2. (Note: Neither user is an admin account.)

Steps: 1. On user 2, launch Thunderbird. 2. Get the dialog that there's an update to 128.7.0esr. 3. Click the Restart to update button. 4. Get the dialog that there's an update to 128.7.0esr. 5. Click the Restart to update button. 6. Get the dialog to enter admin ID and password for installing the Thunderbird helper. 7. Enter the admin ID and password and click OK. 8. Get a (surprise) dialog to authorize Thunderbird to discover my devices. 9. I choose to deny.

Expected result: Thunderbird relaunches, now with 128.7.0esr. Actual result: Get the dialog to enter admin ID and password for installing the Thunderbird helper.

10. Log off user 2 and log on to user 1. 11. Download 128.7.0esr from the Mozilla website. 12. Check the hash. 13. Install, choosing to replace the old Thunderbird in the shared Applications folder. 14. System Settings, About, System report, Applications 15. Verify the signature is signed by Mozilla 16. Launch Thunderbird

Expected and actual result: Thunderbird launches and I can use it normally.

17. Log out of user 1 and log into user 2. 18. Launch Thunderbird

Expected result: Thunderbird launches and I can use it normally. Actual result: Get the dialog to enter admin ID and password for installing the Thunderbird helper.

I'm guessing there's some manner of residual file that's preventing Thunderbird from launching on user 2. I've verified Thunderbird is in the system's Application folder and not in user 1's files.

How do I clear the pending install from user 2 so that Thunderbird will launch for user 2?

Every few months, my message sorting will switch to threaded mode. It did it again within the last couple of days.

I thought maybe it reverts to defaults whenever an update comes through, but update history shows my last update was Sept. 12 (exactly a month ago), and I used T-Bird yesterday, and messages were not threaded then.

I'm thinking that if I change the defaults to "unthreaded", this would stop happening, but I'm curious if it's common for it to randomly switch to the default irrespective of updates.

Would the computer rebooting (whether manually or automatically for, say, Windows updates) cause it to revert to defaults - is that what's going on?

Downloading emails works quickly as normal but reading opening or looking at emails (even ones downloaded weeks ago) is suddenly very slow. There is a pause before anything can be viewed even with a preview screen open.

Version is 128.7 0esr I use bitdefender - but that has never been a problem before Any ideas?

Here is my problem still. I have to close and reopen Thunderbird at times to get my emails. Sometimes the emails can be 2 hours old. I have checked with Xfinity/Comcast and they said it is a Thunderbird problem. I have asked this question before and got no help. What can be done so I get my emails everytime Thunderbird is supposedly checking for emails? I am using Port 993 and IMAP. Should things change at all? Thank you.

My Thunderbird goes through periods where it can receive but not send emails. I am presented with the following message, see attachment. The number may vary but the message is always the same, I am being blacklisted. Can anyone tell me way this is happening, and what to do to fix it, Please? As far as I can remember, it sorts it self out, but it hasn't for over a week now and it is really frustrating. Thank you for reading this plea. Regards Ilio Pieroni

I didn't know there was a non-ESR version of Thunderbird until I found out by chance a few days ago! Since the latest update to ESR 128.5.2 has crashed 11 times this week, I would like to move to the latest version (64 bit?) non-ESR. There must surely be an official Mozilla step-by-step guide to doing this?

Thunderbird had never crashed before, but lately, after the last 2 Windows 10 updates within the last 2 weeks, it crashes. It's at 128.5.2esr, the next-to-last update.

It always crashes when I choose "About" and it starts downloading the update. It appears that it doesn't get the 1st byte before crashing. It will still say 0 bytes when it crashes.

It also crashes if I leave it running and the screen goes through the screen saver mode and turns black. Twice it crashed while I was using it.

I thought it might have something to do with the fact that I had 4,000 emails in my Inbox (is there a limit?), so I deleted many and moved many to folders. I now have just under 1,000 in my Inbox.

I also tried restarting in Troubleshoot Mode and updating, but it still crashed at 0 bytes downloaded.

Is there a way to manually download the update and apply it? I can't find it on the website.

The next thing I know to do is reinstall. Is there anything I can try before doing that? Would you suggest uninstall first or reinstall over what's here?

Thunderbird will run and retrieve messages from account, but keeps crashing after 1-2 minutes each time. There are a lot of archived emails, and 1,500+ in Inbox, but sufficient disk space on the PC.

After working fine for years, Thunderbird stopped receiving email from my POP accounts a month ago and I haven't been able to get it to work since. After weeks of experimentation and frustration, the only way I can get TB to download POP mail is to install and run it in Windows Safe Mode with networking. However, once installed in Windows Safe Mode, TB run in Windows normal mode will successfully send messages from each account.

It would take pages to describe everything I've tried, so I won't. The results of all the tweaking and updates is the system specs below.

I'm at a total loss as to what I've missed or where to look next. I would appreciate any help.

This problem started after the latest Firefox update was installed. I have looked in Thunderbird Solutions but with the only one that comes close to my problem the person was able to switch to a different profile. I don't have another profile that I can do that with. In another one the problem was solved with a bug fix in a newer version. I already have the newest version. ??? Please help.

Please add a feature to disable the unread message counter on certain folders. I don't want to see how many messages I have in the Trash folder, they're in this folder because I don't want to read them, but this counter annoys me

My login to Thunderbird has suddenly stopped working. I am asked for the password for my email account on pop.gmail.com. But when I enter the password for my gmail account it fails. What can I do?

I just reinstalled Windows and then Thunderbird. I'm getting the list of messages but no message preview pane as I'm accustomed to. I found out I can hit the F8 and turn it on/off, but it appears to the side. I like it underneath the message list. I see instructions to click on the "View" to set it up, but I cannot find where this alleged "View" menu item is. I've tried to find it in Settings with no success. Please help me get my message preview pane back as it was in the bottom portion of the screen.

Thanks

I came into my home office this morning and started my Windows 10 machine from scratch (cold boot). I loaded Thunderbird and read and deleted some email. Then I went to enter a Task in the same calendar I always install Tasks in and it won't let me enter a new Task at all. The input field tells me to select a calendar that supports tasks. Well, I have! I open the Events and Messages menu option and the Enter Task command is grayed out. What the heck is going on? How can I get the ability to enter Tasks back?

I'm getting a little tired of dealing with all the issues in Thunderbird. I have spent hours trying to debug this with no success.

Hello! I am developing an application for an organization that uses Thunderbird in a Windows environment. Among other features, it is necessary to implement the transfer of mail client settings from one workstation to another. Built-in Mozilla Thunderbird tools are not suitable. I am still considering implementation options (autoconfig or direct work with files), and I have several questions. I will be very grateful for any help. 1. What is the minimum required files in the appdata folder that I need to create (transfer) so that the profile works without errors on the new workstation? No need to transfer messages, they are all on the server, and offline work is not used 2. How does the installs.ini file work? I need to avoid creating a new profile when starting Thunderbird for the first time, do I need to create an entry in installs.ini, and if so, where can I get the correct installation code? 3. Is it possible to transfer saved passwords to a new workstation? What are the requirements for this? I am very grateful for any answers

If this is possible, how do I create filters for incoming emails from specific writers and/or subjects to go directly to specific folder/sub-folders? (I'm looking through the info here, but haven't come across this.)
