I have had so much trouble with version 115 and looked online for answers. People recommended downgrading to 102, so I downloaded and re-installed that version, after deleting the file that was recommended from the Thunderbird folder (now I can't find the name of it!).

When I installed 102, it gave me the profile error message. I started to create a new profile and realized that will take me hours probably - I have multiple folders and email addresses in TB. So I decided to reinstall 115, and now it looks like there is no data at all. Help!

I'm using Windows 8.

Thanks

When trying to click on links inside PDFs, the url is changed to undefined, producing an error message. For example, a Hostgator article is converted from https://hostgator.com/help/article/how-do-i-change-my-dns-or-name-servers to https://undefined/help/article/how-do-i-change-my-dns-or-name-servers

I have tried clearing the cache, troubleshooting, and get the same result in safe mode, and reverting back to Firefox default settings. And I still get the same result. I've attached an image of the error message.

YouTube videos on Firefox getting slower and jerky. After refreshing Firefox (Settings -> Help -> More troubleshooting information -> Refresh Firefox), it is OK, but only for a short while. Then the problem starts again. Same YouTube videos are running fine with Chrome at the same time.

Running Windows 11 Pro (Clean windows setup not long ago and the issue was there from the beginning.) German Language Firefox 116.0.2 Build ID 20230805021307 Intel CPU i7-1360P, 16 GB RAM, 1TB M.2 SSD

Would really appreciate a solution for the issue because I really like Firefox!

Many times now, I have needed to change folder views to 'Unthreaded', ditch 'Correspondents' in favour of 'From' and 'Recipient' and arrange my emails in descending date order. Every time I create a new folder, I need to go through the same routine. Every time I download a new version of Thunderbird, all my folders are changed back to 'Threaded' and 'Correspondents' and are in Ascending date order, so I have to go through the whole process again. What I need is a simple 'global' setting in a menu, so that I can change the settings for ALL my Thunderbird folders in a simple series of clicks, without needing to go to each folder every time. Better still would be a 'once for all' fix that would prevent Thunderbird changing my settings every time I download a new version. There must be thousands of Thunderbird users who share my frustration with what is lotherwise an excellent email program. Please fix it!

I just updated to the latest version of Firefox, and all of a sudden I have a new icon, Extensions, that looks like a puzzle piece, I cant seem to be able to remove it....at all.

During a recent outage Thunderbird "send" function was disabled. This has happened before during previous Internet service maintenance On this occasion the thunderbird .exe program was employed which resulted in creation of a new email service, even though email address was the same etc.. The new account 'eventually' reloaded the inbox with current messages, however the address book is empty and the file structure of saved info is also deleted. Q. Is it possible to recover the data which did not reload ??? email address is "[edited email from public] @tpg.com.au"

I updated to ver. 102.1.2 from withing Tbird but had to roll back to version 91.12.0 because new messages showed only the Subject but not message body. Has this been fixed yet?

Hi, I just got a new HP Windows 11 desktop. I used Thunderbird on my old Dell Windows 10 PC fine. I have Spectrum for email and it's time warner cable twc.com they are also Charter. My new PC came with a trial of McAfee. I am having a problem I saw someone else post where I can receive email but not send I get error about timed out and just now got this Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) .gmail.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again. I asked Spectrum if it had to do with Mcafee they said no to contact you all. They said my settings are right which I copied off my old PC. I thought I used to always be pop3 but they said it's imap. I receive just fine just can't send. It worked on my old PC fine. Thanks!

Since upgrading to Thunderbird 102, I can no longer see nor download any new posts to NNTP newsgroups. When I try to get messages, there is a "flash" giving some number of messages, but they never download. It also seems that any posts I try to make aren't made.

"Thunderbird can't update to the latest version

Download a fresh copy of Thunderbird and we'll help you to install it"

How can I be rid of this annoyance? The "latest copy" to download is what I'm already running! This began with my update to version 91.10.0 from the previous version.

As shown in the attached screen capture, recently these subfolders of "sent" have appeared to the left of the folder. They make the folders undeleteable. How do I get rid of them? I want to delete "sent" and create a fresh new "sent" folder.

Thanks John

I have a very small Tablet computer and Thunderbird is really bogged down on it. The tablet has a 32 bit processor, 1G RAM, 64G SD drive. (1) When I run TB I get many "not responding" messages from Windows. (2) Maybe 1/2 the time, if I "delete" a message the screen will freeze on the message. The message is removed from the inbox list. I have to click "X" to get rid of that screen. (3) Get Messages no longer works. When I click it, nothing happens. The status bar at the bottom remains on the last information displayed. I found that if I use View, Folders, All, I can bump TB to get messages. (Normally I use Unified Folders) The status bar will display each of the accounts it is checking and any new messages will appear. These things have been happening through many many versions of TB. Although #3 seemed fixed a few weeks ago but has returned. Same for #2.

I looked at the disk space that TB is using and found that TB is using over 10GB. See attached. I don't know why it is so large. I don't need to store any messages on this computer. I have a desktop that is my "base station" where I want to save all (but deleted) messages.

I don't know if this large amount of TB space is contributing to the problem. Any help would be appreciated.

I have a System 76 laptop running Ubuntu 14.04 LTS. The LTS (Long Term Support) ended years ago with Firefox 66. All of that works fine still. My problem is: 1. The world is telling me to upgrade my browser. 2. Mozilla tells me "Note: If you use your Linux distribution's packaged version of Firefox, you will need to wait for an updated package to be released to its package repository. This article only applies if you installed Firefox manually (without using your distribution's package manager)." 3. There will never be an updated package because LTS has ended. 4. IS THERE A WAY TO MANUALLY INSTALL A NEWER BROWSER LIKE FIREFOX 123?

I have created a HTML signature, defining the font, size, color and bold - as below However, the color is not taking effect and remains black, despite it showing so in web based html editors.
