I have an 8 year old PC that I have been using Thunderbird on its entire life. I have 5 email accounts (from my own website if that matters) on it for personal use that have tons of information.

I bought a new computer and have not been able to move my old data to it. The old computer uses Windows 10 with Thunderbird Version 115.5.2 (32 bit). The new computer uses Windows 11 and I have tried several Thunderbird versions with the current one being 128.12 0esr (32 bit). I have added one of my email accounts to my new computer, but it contains none of my previous data (emails, contacts, directories, etc.), just a bare bones account that only receives new email.

I have repeatedly tried to move my entire source computer setup and data going through all of the described steps including copying the previous Thunderbird folder to a flash drive. I then follow the directions for copying and pasting my source data into the new computer's "roaming" section. It goes through all the steps including asking if I want to overwrite existing files. I have almost 14,000 files and as the process continues, I can see file names being added just as I would expect.

After everything is complete, when I restart Thunderbird, the only access I have is once again to the bare bones new email account. There is no data, nothing at all, from my source computer.

Help please, this has gotten beyond frustrating.

literally what the [expletive] was the thought process in making it so that when u import all ur passwords from a csv it AUTOMATICALLY DELETES "DUPLICATES" WITHOUT CHECKING AT ALL WHICH ONE IS CORRECT. I HAVE SO MANY [expletive] PASSWORDS THAT ARE WRONG BECAUSE UR [expletive] BROWSER DOESNT ALLOW ME TO [expletive] MANUALLY CHANGE THAT STUPID OPTION. WHAT THE [expletive] WAS THE THOUGHT PROCESS IN MAKING IT [expletive] AUTOMATIC???

Hello everyone. I use the firefox browser for years with the windows 10. I used to click on a favorite website with the right mouse button. Drag and drop on the Firefox icon in the taskbar at the bottom of the monitor. When I need this website again, I would just right click on the firefox Icon in the taskbar and would see a list of all my saved websites. I would select the website I wanted and that opened my preferred website oince again. Since I have upgraded to windows 11 this no longer works. Can anyone tell me if this is still possibke to save the preferred websites in the firefox icon in the taskbar? Any help would be greatly appreciated. Thank you

Please I want to remove Ai from Firefox Mozila permanently on Windows 11 for all users/profiles:

I tried a lot of workarounds but they are unsuccessfully: I tried to create extensions (Hide Gemini, AI Google Overview), but they do not work for all users; only profile-based extensions are supported. I tried to use preferences using internal settings on Firefox, but it does not apply to all users. I tried using a script on PowerShell for all users merging internal preferences, but it does not work I copied the local and roaming settings from Firefox to the Default profile, but it was unsuccessful.

I also tried to remove "All" from the search page, but I moved the seach to go to the tab "Web" only.

Thank you for any help and feedbacks. --Rod

Have just installed TB for the first time (replacing WLM) and am very happy with it. My only problem is that the option to open with a blank page is not working despite leaving the checkbox unchecked. I've tried checking and unchecking but it makes no difference, it always opens with the full setup options displayed. Is there another way to have TB open with a blank page?

For >20 years I have used Thunderbird as my email reader for various email accounts on my mac laptop. Last night Thunderbird stopped downloading emails from my yale.edu account. I tried removing the yale account and reinstalling it unsuccessfully. See attachment. The Yale IT rep told me that Yale very recently added security features that are probably preventing Thunderbird from working with it. They told me to use the Outlook app. Is there anyway I can get Thunderbird to work with my yale.edu outlook email account?

Hi. I'm asking this question because I'm not quite sure how to describe this issue through a Google search. Recently, I've noticed that whenever I click and drag anything, an icon will pop up while I'm doing so. Attached is an example, I click-and-dragged on the "Learn More" hyperlink off to the right.

Is there any way to disable the icon that pops up? It bothers me and seems to slow things down, which isn't ideal. I'm not the most well-versed when it comes to Firefox's more advanced settings (the options in about:config and whatnot) so I wouldn't know where to start.

Please,

I have a Debian 11 VAIO laptop, with Firefox ESR 115.14.0esr 64.

I have tried the settings menus (there is nothing about translation there, not even in languages.

Tried as well the about:config (several entries).

Nothing happens, annoying auto-translation bar shows up all the time and automatically translates several languages.

Really can't stand any longer...

Please help!

Appreciate.

Certificate errors have been an ongoing, several-times-a-day frustration for me and other users, with different ISPs, since approximately June 25. Is anyone working on this bug? Because it clearly is a bug: Not only I but several other users have reported that Thunderbird worked fine until that date, then stopped working fine. What changed, and can it be put back the way it was, or can we receive some explicit instructions on how to fix it for ourselves? It's making Thunderbird borderline unusable. Every time I try to send a message, I have to confirm a security exception, then send it again. Several times a day, when I try to fetch messages, I have to confirm security exceptions. The confirmations never seem to stick. This is some BS.

I am able to style tasks that are either completed/overdue/inprogress in userChrome.css . But so far I have not found a way to style canceled tasks.

Can someone help me ?

TB on PC: have noticed that my Calendar entries are not syncing up to Outlook.com. Entries added directly to Outlook.com sync okay to my PC TB. Contacts sync works fine both ways. I just upgraded to TB 128.12 but no change. I have checked all the TB Outlook server entries and they appear correct. Any ideas? Thanks.

I have the most recent update and have been excited about tab groups, but it's still not working on mine. I thought the update would be available to all as of May 6, 2025. Is this happening to anyone else?

Could someone please tell me what the latest version of Thunderbird is on the Release Update Channel? I am on version 139.0.2, and when I check for updates in the app, it says that Thunderbird is up-to-date. Is version 140.0 not going to be available on the Release Update Channel?

I am unable to get access to my Gmail accounts. Every time I select a bookmark link to Google email I get server time out error pages. I have looked at Windows 10(64) Firewall settings and I do not find anything blocking Firefox from accessing the internet(Inbound or Outbound Rules) are set to allow. NordVPN is not set to block any program or connection. I have never seen anything block access to Google.com or any related pages within Google. HELP Please!

With the latest updates, the client no longer accepts the self-signed smtp certificate as exceptions. The server is old and there is no way to upgrade to a newer one. It is also not possible to connect a third-party certification authority
