Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.

Good morning, I had asked a question early on Saturday, but was unavailable the rest of the weekend so just now responding to associate Corey Bryan's answer. I had gotten a message that I am using an unsupported version and they recommend downloading the latest stable version.

He said it appears that I'm on the "Release" channel and most likely want to be on the ESR channel. I also mentioned that I am a cave-man when it comes to anything computer and am very skittish about making any changes as I don't how to straighten out any errors that might occur.

He asked me where I installed Thunderbird from and the answer is that I don't know. It was an IT guy that did it many years ago.

So I guess my questions are, if I've been using this version for years, do I need to or should I update it? If so, if I click on the latest stable version of Thunderbird, will that change anything on my computer, aside from getting the newer version of T-Bird? And will my e-mails in Thunderbird look any different?

Thanks very much for the help. Tony

I understand that Postbox, based on Thunderbird, will never be updated to become compatible with Apple silicon chips. Therefore Postbox will cease to work when Rosetta will be deprecated on macs. Consequently my question is where can I find directions to import messages, filters, and preferences from Postbox to Thunderbird?

A few weeks ago after an automatic update I ended up having Thunderbird version 131.0.1 installed, I have no idea how this happened. On opening I get a message telling me I shouldn't be using a beta version and that I should revert to the latest general release version (128.4)

Today when I had some free time I downloaded 128.4 and installed it. On opening it it says that I can't use a profile file from a later version with the earlier version. Is there a way to recover from this WITHOUT having to set up the whole profile again from scratch.

Meanwhile I have done a system restore so I am back with 131.0.1 It has not given me any problems so far. Is there a new general release version imminent that will get me back on track?

I would appreciate any help I am not a computer expert, just a user, and find Thunderbird a very good email client.

I had to restart my Mac. When TB restarted during relaunch of the Mac, it was like TB starting fresh. It didn't display my email accounts, or my folders with saved emails, etc.

I quit TB and looked for it in my Applications folder - and I found two versions of TB. Inside the Thunderbird folder was version 140.9.0esr. Outside the Thunderbird folder was version 150.0. See attached screen grab.

I thought I should try launching the newer version (which was outside the folder). So I moved the 140.9.0 version to the trash, then launched the newer version – and it had the same problem. It looked like I was starting TB from scratch.

Next I quit TB (the newer version) and moved the older version out of the trash and back into the TB folder and double-clicked on it. A dialog box popped up saying that the file is damaged and can't be launched.

So I tried launching the newer version again, and it still looks like starting from scratch.

I really hope somebody can help me solve this. I can't access any of my email accounts or any of my stored emails. I use email for work (as most of us do), so this is crippling me.

Thanks in advance for any help.

Can current Thunderbird (52.5.2) still import old mail from Outlook Express (on Windows XP SP3)?

Or should I try to install an older version like v38.5.0?

I also have my mail in Outlook 2003 & 2007, but I read Thunderbird hasn't been able to import from a .PST for a long time (since v.17 or so). Let me know if I'm on the right track (and which track is best). I stuck with Outlook far too long. Any help would be greatly appreciated.

Help! TB 60 continuously crashes on all of our machines so we're using 52.9 until the bug is figured out, BUT TB insists on auto-updating to version 60 despite turning off auto-update settings. These are the exact non-default update settings we have. Can you help me figure out why TB continues to auto-update?

user_pref("app.update.auto", false); user_pref("app.update.channel", ""); user_pref("app.update.enabled", false); user_pref("app.update.lastUpdateTime.addon-background-update-timer", 1536598499); user_pref("app.update.lastUpdateTime.background-update-timer", 1536598626); user_pref("app.update.lastUpdateTime.blocklist-background-update-timer", 1536598371); user_pref("app.update.lastUpdateTime.search-engine-update-timer", 1536599735); user_pref("app.update.lastUpdateTime.telemetry_modules_ping", 0); user_pref("app.update.lastUpdateTime.xpi-signature-verification", 1536599607); user_pref("app.update.migrated.updateDir", true); user_pref("app.update.service.enabled", false); user_pref("app.update.showInstalledUI", false);

I've - I hope! - followed all the Thunderbird Support instructions on moving a Profile from one computer to another with a different OS (save a copy of the profile file from the first computer, download and install TB on new computer, locate its "Profile" folder, and then either paste the contents of the former profile file into the new profile file [thus overwriting the latter]), then open TB . . . but it didn't work.

I then tried the same, but with a slightly different method: I copied the name of the new profile file, gave it to the old computer's profile file, then renamed the new profile file, and pasted the old profile file -- now with the proper new name -- into the new directory. . . that, too, didn't work.

I've spent a few hours trying to get this to work, and am nearing the point of giving up on TB as an email solution.

Any help would be very welcome!

I know that typically mozilla does not put a low bound on advisories, and https://www.mozilla.org/en-US/security/advisories/mfsa2024-40/ is the advisory for vulnerabilities fixed in ESR 128.2. CVE-2024-8387 is listed here. yet the advisory for 115, https://www.mozilla.org/en-US/security/advisories/mfsa2024-41/ does not list this vulnerability. Was this something that was only impacting 128 (for the ESR builds) or is there a mistake that either 115.15 did patch it but it wasn't documented, or the patch has been missed and ESR 115 is still vulnerable?

Hello,

I would like to obtain the complete release history of Firefox ESR Portable, including:

The exact release date of each Firefox ESR Portable version. The corresponding Firefox ESR version number (e.g., 115.x ESR, 128.x ESR, 140.x ESR, etc.). Any available information regarding delays between the release of Firefox ESR by Mozilla and the release of Firefox ESR Portable.

Could you please provide a list of all Firefox ESR Portable releases along with their release dates, or direct me to an official source where this information can be found?

Thank you for your assistance.

hi i'm at my whits end trying to get my data across from windows mail. I paid someone to sort this, and he said it will continue to say the connection is lost while getting data across from windows mail. its been a week now. i cant get it to work properly. none of my addresses are there, mail continues to not arrive at my PC (when I've got it on my phone), it just keeps saying loading message 1 of 3457. but never gets to the total. the number has remained the same for many days now so obviously its loaded all the emails, but it still appears stuck. also the preview window seems to not work (has worked once or twice). frustrated...

dont want to buy stupid microsoft products but i just cant work this way?

I made a mistake. I had 128 and went up to 140. It pretty much looks the same, but a big difference is an extension I always use says it will not work with 140. I don't care how good 140 might be; if I can't use my app, QUICKTEXT, then I don't need this. How do I go back to 128 or to a version that works with my extension?

I have a custom pitch black theme ( pls add it without addons ) which now only flashes for a second when i open the browser and returns to the normal greyish dark mode. When i go to Firefox Color addon page and load it again in saved themes it stays pitchblack even if i open another browser window until i close all the browser windows .

I run Mac OS X version 10.11.6, El Capitan. I have used Apple's Mail.app for many years. I'm trying to convert to Thunderbird, version 52.5.2. I have successfully created a TB account, but I have not been able to create usable copies of any of my Mail.app mailboxes in TB.

I have faithfully followed "Importing Apple Mail messages" in the page titled "Switching from Apple Mail to Thunderbird". That method thinks it works, but imports exactly 0 mailboxes.

I also went through all of "Install, Migrate and Update" multiple times, but nothing there helps.

Finally, I tried TB's Events and Tasks --> Import... path, but that processes only files of types .ics (for calendars) .csv "Outlook Comma Separated Values (*.csv)" (or .ics for calendars).

I did discover that Mail.app has an "Export Mailbox..." option, which will produce a mname.mbox directory for each exported mailbox. I've tried getting TB to use that as input by copying it to the Local Folders directory before starting TB. TB somewhat recognizes the .mbox folders that are there, but it doesn't show the mail to me when I select them.

So the question is: How DO I get my current mail copied to TB?

Dear Sir or Madam,

I need your help.

My Thunderbird shortcut no longer opens. The shortcut C:/Online/Thunderbird is empty. The folder no longer exists and my Thunderbird can no longer be found after an update on November 1.

I can still find Thunderbird version 128.4.0 260MB from 1.11.24 and my old profile from 7.11. under Windows Programe.

What can I do to get my Thunderbird back? Reinstall Thunderbird and integrate the profile?

I haven't actively deleted the program and can't remember updating it.

I was just able to save the profile to a USB stick.

Many thanks in advance for your efforts

German Kann die Verknüpfung von Thunderbird nicht mehr öffnen. Diese ist nicht mehr auffindbar.. Mein Thunderbird ist wohl nach einem Update am 1.11. nicht mehr auffindbar. Finde unter Programe Thunderbird Version 128.4.0 260MB vom 1.11.24 und mein alten Profil vom 7.11. noch. Was kann ich tun um mein Thunderbird wieder zu erhalten? Neu installieren und das Profil einbinden? Habe aktiv das das Programm nicht gelöscht und kann mich an ein Update auch nicht erinnern.. Konnte das Profil gerade auf einen USB-Stick sichern

Currently on 131.0.3. Started having this issue around the time 131 dropped.

I press Ctrl-shift-O and bookmarks manager won't open. Bookmarks manager opens normally if I use the menu to open it. Keybind won't work in troubleshooting mode so I know it's not an addon, and the hotkey works fine on other computers with Sync enabled so I know it doesn't have to do with my synchronized settings. Also won't open with a fresh profile so I am very hesitant to reset all my settings.

I use this keybind multiple times per browsing session so it has had a major impact on my usage. Not sure what to do. Please help!

I'm going to try a graphics driver update in the hope that helps. This is on Windows btw.

I have installed and am running Thunderbird on my new laptop, and would like to use the profile from my old computer. I have followed the instructions provided, and copied the profile (renamed) into the folder on the new laptop. When I run "thunderbird.exe-p" I receive a message "cannot find Thunderbird.exe-p" and asked to try again, but without success. I would be grateful for help on this problem. With thanks Alan
