   Under 'Application Basics' - Profile Folder - click on 'Open Folder' 

This opens a new window showing the contents of your current in use profile name folder.

   Exit Thunderbird now - this is important. 

Look for the following files and delete them.

   cert8.db - obselete file
   cert9.db - currently used file
   key3.db - obselete file
   key4.db - current used file
   logins.json - current used file
   pkcs11.txt (some people report this file missing)
   secmod.db - obselete file
   session.json
   xulstore.json 

See next comment before you start Thunderbird as you need to empty cache files.

ADDITIONAL Whilst Thunderbird is closed - after you have deleted the files mentioned previously.

access : C:/Users/ User Account/Appdata/Local/Thunderbird/Profiles/ Please note this is the Appdata 'Local' location which the computer uses as a cache. Be sure you are in the 'Local' and not the 'Roaming' Delete the contents of the 'Profiles' folder.

then start Thunderbird. keep having to reset my secure key password and tried this in "Roaming" instead of "Local" Help!

I've been using Firefox and Gmail on my PC and android phone for years. Today I can't log into my gmail account on my PC and instead it redirects to google support and goes on about clearing cache etc etc. I have cleared the cache but no different. I have restarted my pc and no different. PC is Windows 10.

I can log in to gmail using Google Chrome so I can't see that it is a Google problem. I can also log in ok on my Android phone.

Is this a Firefox issue?

I use Google search and do not like the AI overview feature. In the Chrome, Edge, and Opera browser I've added an extension that blocks the AI. What I've noticed when I use FF I see no AI results when using Google search and I've not added an AI overview block extension. Is there something different about FF that prevents AI results from showing without the need for an extension? I look forward to your comments. Thanks

I recently sent mail to two (2) separate sites recently. One was a dot gov and the other a dot com. The multi-line text content of both messages has been replaced by the identical single line:

ScreenShot attached.

I haven't yet searched other messages for the occurrence.

What has happened? I need the original texts restored, and also to prevent any future recurrence.

Thunderbird 128.3.1esr (32-bit) Win10 Home 19045.5011 64-bit (fully up-to-date.) HP Notebook

How can I set the email message sort to descending date for all folders in all accounts? With many accounts with many folders each, manually changing the sort from ascending to descending is a lot of needless work. A global default is needed, and if there is one, I can't find it.

Friends: I was running 91.13.1 for the longest time and upgraded to 128 (Nebula) which is a disaster. So many bugs. I kept saying they ruined a great software. E.g., search was totally broken: take forever and doesn't work. Resizing columns is a pain but I realized 115 was the same way.

Challenge: profile gets upgraded too and can't downgrade. But I pulled out backup of a) program b) profile from backup. Replaced everything except the Mail (and its subfolder Local Folders) Replaced the program to 91.13.1 Worked like a champ ~~ upgraded to 115.12.2 - terrible - nicer UI e.g. resizing but same issues as Nebula described above (with columns, search etc.). ~~ downgraded back to 91 - got the profile back upgraded to 102.13.0 Jul 2023: https://thunderbird.en.uptodown.com/mac/download/104978201 (downloaded from: https://thunderbird.en.uptodown.com/mac/versions) ~~~ The designers of this great software broke the UI after 115. Happy to be back at 91.13.1 and won't upgrade for a loooong time, if ever. Best Regards

I am using Thunderbird version 128.3.1 esr Every time I view an email in the preview pane and start to scroll down, the preview screen jumps back to the top of the email. This happens at least once, and several times in a few emails. Does anyone have an idea what is causing this and/or how to correct it?

I use a web application that lists items in a table, which provides a link to download the table as a CSV file. It used to work fine in previous versions of Firefox. However, in the current version, while the file save dialog defaults to a filename that ends in .csv and CSV is selected in the "Save as type:" drop-down, the data in the file that Firefox actually saves is in XML rather than CSV format. I don't know in which version of Firefox this behavior changed, as it's been a couple years since I tried to use this feature. Or I suppose it actually could be a new bug. I do know that when I use the same feature in Microsoft Edge, it saves the CSV file in the correct format, so this behavior seems to be peculiar to Firefox, rather than anything wrong with the web application.

For months I was experiencing the problem of "Thunderbird not responding" occasionally. It was a short duration issue (a few seconds to a minute). I reinstalled Thunderbird several times without success. I read almost every comment available online about this problem and I tried many ideas and recommendations I found without success. Most recently the problem became so serious that it was not a nuisance any longer. It was nearly impossble to work waiting for minutes to open an email or to continue typing while preparing a message and being interrupted by the problem I am describing. I ran Thunderbird in safe mode and determined that none of the add-ons is causing the problem. I turned the firewall OFF and determined that firewall was not causing the problem. I then decided to run Thunderbird in Offline mode and found that the program works normally. Then while in Offline mode I decided to download more messages and the program asked me if I wanted to switch to the Online mode. I said yes. New emails were downloaded and without going back to the Offline mode I was able to work normally without any occurrence of the "Thunderbird not responding" problem. I have been using this workaround for several days now. I download a number of eamails. I try working in Online mode and I cannot do it. I switch to Offline and work fine. I switch back to Online mode and I don't see the problem any longer for the whole day. Do you have any idea as to the origin of my proble? I am running Thunderbird 115.10.2 64 bit on Windows 11. I had the problem originally using Lenovo T490s and more recenlt Lenovo X1 Yoga

I have been using Thunderbird for IMAP email for more than a decade. I have only two folders that contain emails on the server, Inbox and Sent. All the sent emails are there going back to 2009. I periodically move Inbox emails to local folders, but the emails from 2021 to now are still on the server. I see the headers for all of them in Thunderbird, but when I click on the header of an email from between mid-2022 and a few weeks ago, the result is blank. However, when I use my provider's Control Panel to read these emails, the texts and attachments are there, and I can read them. How can I restore my ability to read these emails in Thunderbird? I am hoping there is some simple setting…

Thanks for any help.

I only opened 5 pages (fixed tabs), and only enabled two plug-ins, Proxy SwitchyOmega and AdGuard AdBlocker. The browser was always open, and the pages were static, and nothing was playing. The strange thing is that it didn't take up much memory at the beginning, but it took up more and more memory over time. Today the system got stuck and couldn't respond (it might be that the system used virtual memory).

I used the browser's task manager, which showed that the Shared Web Process memory of several pages was very high, some as high as 4G, and the GPU memory was also higher than before.

I think this is very strange. Why does the memory usage increase exponentially after the webpage has been there for a while?

My settings and usage habits have basically not changed. I didn't have this problem before, but it has appeared in the past six months. I have updated many versions, but the problem still exists. I have always used Firefox. If it continues like this, I will be very disappointed and have to make changes.

Firefox updated to version 131.0 64 bit. Bill payment functions on my banking web site stopped working. I cleared cache and cookies and restarted PC but didn't fix it. I tried using Microsoft Edge and the banking web site worked as always. The bank IT person said it was a Firefox problem. Also, the site says not to block 3rd party cookies, enable cookie tracking and cross-site tracking. In Firefox, I made all changes to allow these things for this site but it still doesn't work. Looks like the latest Firefox update is causing a problem that always worked in the past, while trying to fix something else.

Up to now Thunderbird was installed on C:, while the profiles directory was on D: (including the local files). As C: was getting saturated, I installed the latest version of Thunderbird on D:, and used the Profile Manager to tell it to load the existing profile. Upon launching Thunderbird, it did find all the connected accounts and connect to them, yet didn't display any local files. However, when I look at the location of the local folders in the new installation, it points to the "old" local folders, D:\Users\[user]\AppData\Roaming\Thunderbird\Profiles\Mail\Local Folders, and all the local files I used to see in the previous installation are there. Yet they don't display in the "new" Thunderbid. How come? What should I do? Thanks for any help.

I have been using thunderbird for years and have 2 lightning calendars. These are stored locally in home/.thunderbird on Ubuntu - currently 24.01.1LTS, TB version just updated to 128.3.0esr. About a week ago I stopped being able to save calendar events, getting the message

An error occurred when writing to the calendar Home! Please see below for more information. Error code: MODIFICATION_FAILED. Description: Failed to write to calendar file file:///home/alasdair/.thunderbird/Home.ics: Could not create unique file in `/home/alasdair/.thunderbird' (NS_ERROR_FILE_ACCESS_DENIED)

I have uninstalled and reinstalled thunderbird to no effect. As I am the only user of the machine all prcesses run as me, the .thunderbird directory is owned by me and I have all permissions on it, as I have for all files in the directory. I can create and edit files there no problem. I have no idea how to d=fix this.

Outlook sent me an email on 3rd July stating "Update your sign-in technology before September 16th, 2024 to maintain email access."

As of today, 23rd July 2024, I am unable to access my Outlook email account through Thunderbird as it repeatedly asks me for a new password. Is there any way to resolve this and continue receiving my Outlook. com emails through Thunderbird?.

I do not want to access my emails through the Outlook app.

Version of Thunderbird I am using is 115.13.0 (64-bit), on an M1 Macbook Pro running Mac OS Sonoma 14.5.

Thanks for your assistance.

I recently added a new 'message filter' setting to Thunderbird, to redirect some of my received emails to a local folder. After doing this i do not get any indication of a redirected email being received, no sound & no count on the icon. I do still Get both sound and count indication for messages that remain in the main account folder. All other settings are correct and working. Am i missing something or is this a bug ?.

Thanks.

A few days ago I got a popup notice of a Firefox update. I clicked to download the update and away it went. However, since that update was installed, Firefox crashes several times a day. I click on the 'Tell Mozilla' button and restart my session, but then it happens again. Am I the only one who is seeing this?

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.
