I'm running Thunderbird on Mac OS 15.3. I have two POP accounts in Thunderbird; the configuration has been stable for years. This evening, I went to add a new account, and Thunderbird seemed to have decided to update itself, including flipping me over to Chrome where it opened a page about Supernova.

Thunderbird relaunched and came up with an empty "Chat" window. My usual mail window is gone -- and I can't get it back. I can't get an "About Thunderbird" window to open.

I actually can't figure out what happened. My mail appears to be gone. My accounts seem to be gone. I can't open Settings, I can't open Account Settings.

Wait, the mail accounts seem to still exist -- I can tell Thunderbird to check mail, and the POP server shows the checks happening -- but if I send mail to myself, nothing opens. Also, all of the Layout menu options are greyed out.

Help? :-)

Thanks, Vince

I am on 115.13.0 (32-bit) yes, and oddly it says updates disabled by system admin (that's me). I have no idea how to change that. No way I took steps to disable thunderbird updates. I found only one thread on how to reenable but it was very vague and the OP did not arrive at a perfect fix.

This has been re-posted. In error my first post said ‘Firefox’ NOT ‘Thunderbird’.

Hi all. I recently had a terminal problem on my Win 10 computer so have bought a new Win 11 machine. I ran Thunderbird mail on the old Win 10, had 5 email accounts, had about 12 local folders and had my Profile stored in a folder on the desktop. The folder was moved there some years ago but don 't remember how I did it. I moved it there because this folder gets backed up every night.

So, I have managed to remove the HDD from my old machine and have located the 'old' profile folder. I now need to re-install Thunderbird on the new machine and match it up to my old profile folder (I think...)

Any advice on how to do that?

Since yesterday I have Thunderbird nebula 128.2.3esr on my Windows 10. But I cannot find my calendar and the new left sidebar isn't available, but only a little button on the left upper corner with seven button without function. I've tried a lot, I cannot find any description about a same failure in the Internet.

I've been on Thunderbird for almost 20 years and a Mozilla fan. Have evolved a fairly elaborate configuration of local (POP) email folders, rules, calendar, and accounts to manage & organize email activity, retention, archiving, etc. I've not had to deal with Profiles in previous upgrades and don't have much experience with it.

The recent Oct 1 push of Firefox & Thunderbird 131.0 releases took me by surprise. I was able to re-implement the previous Firefox profile to recover bookmarks, cookies, passwords, etc. However, when T-Bird warned that 131.0 was Beta & unsupported I took the suggestion to download & install the current supported release: 128.3.0 (I was on 128.2.3). Then hell came.

Once downloaded, installed & launched, Thunderbird 128.3 cautioned the new profile created with T-Bird 131.0 was incompatible with previous versions and that I should create a new one, which I did. Still could not get new T-Bird to recognize previous profile, so I tried uninstalling, downloading & reinstalling 128.3 multiple times, each time prompted to create a new profile before proceeding. I tried to follow the previous profile restoration process detailed on support forums & articles, but none seemed specifically relevant to my situation.

I located my profiles in the appdata roaming profile folder, including what I think are most recent based on size of mail folders. Can't determine whether I had just one or several in use due to the extent of my setup. Could really use some help & advice to: 1) Determine which profile was in most recent use prior to T-Bird upgrade. 2) Whether more than one profile was in use. 3) Re-implement the profile I was using on T-Bird 128.2.3 with my new 128.3.0

Regards & many thanks in advance, John C Houston

PS You'll ask why I would upgrade to 131.0 from 128.2.3. Answer: it was on auto-update and 131.0 is what was pushed. No more auto-updates for this guy!

I am about to set up a new Windows 11 laptop. The old one is a Win10 one, running Thunderbird 128.4.3 32-bit. Note I haven't upgraded to 5.2esr yet. My Thunderbird profile as recorded by Mozbackup is about 16GB - most of this is archived in Local Folders. I have 15 email accounts (using four different domains, none of them are gmail or hotmail etc) and a newsgroup.

I've looked at various answers (and problems!) around these factors and cannot see the wood for the trees. Can anybody tell me - or direct me to - a clear description of how to go about this? Some questions are:

1. Can I install 64-bit on the new laptop and copy over the old 32-bit profile? If not, is there any problem in continuing to use a 32 bit Thunderbird? I am getting a lot of hanging/not responding in the current TB. Note I haven't upgraded to 5.2esr yet.

2. How do I ensure that all the archived mail is transferred without problems? I haven't compacted anything lately, since I noticed that sometimes a message stub is retained where the message body seems to have disappeared, and that compacting risks deleting even the message stub, which can be useful.

3. I've been using MozBackup for ages now but it is really ancient - is there a more up-to-date backup that would be reliable?

Thanks in advance! I'm planning on do the new installations at the weekend but anything I can do to prepare would be useful to know!

I recently upgraded from Thunderbird 116 to 128 on Kubuntu 22.04, since then it has crashed at least once every day.

For some reason it is unable to send a crash report, instead I get the attached window pop up.

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?

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.

Thunderbird came back looking totally different after a power outage. More like 5 of them in a 30 seconds. No matter what settings I use, it doesn't look like it used to and I do not like what I have now. It is still what I like on my laptop. When I try the export function the file is much larger than the 2 gigs. I do not understand what to do when it says to back it up yourself. I have included a screen shot on how it should look.

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.

There must have been an update for Thunderbird that screwed up the way I have been using Thunderbird for years now. I had sub folders under inbox. For example, I had an investment newsletter go into a sub folder under inbox labelled "inv". I had a filter set up to move emails that had the name of the newsletter in the title to go to that "inv" folder. In this new version of Thunderbird, those separate sub folders are gone. The filters are still there but the folders are gone. Now all emails just go into the inbox. Is there a way to roll back to a previous version?

TIA Eric

It seems from reading on forums and googling that there is a "return receipt" function in Thunderbird. My problem is I can't find it anywhere in my software. I've searched in every category and can't even find an "Options" on the menu. I remember when Thunderbird did have a "return receipt" that was very easy to find. Now it seems that it has disappeared altogether. What gives?

A friendly hello to whomever is kind enough to read this! Your help is greatly appreciated!

The latest update caused an edit I made to my Profile's userChrome.css file to be nullified. Now there's huge bar where the tabs toolbar used to be, and apparently it's not the title bar, as when I activate the title bar in "Customize Toolbar," this huge gets replaced by the actual toolbar.

I've attached my css code below for inspection. It used to work perfectly, but after the last update (133.0) it's no longer working. What can I do to fix this and have it like I had it prior to the latest update (133.0)?

userChrome.css File: `#main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {

 opacity: 0;
 pointer-events: none;

}

1. main-window:not([tabsintitlebar="true"]) #TabsToolbar {

   visibility: collapse !important;

}

1. main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar .titlebar-spacer {

       border-inline-end: none;

}

/* Adding empty space for buttons */

1. nav-bar {

margin-right:140px; }

/* 15px for dragging whole window by mouse*/

1. titlebar {

appearance: none !important; height: 15px; }

/* Fix for main menu calling by Alt button */

1. titlebar > #toolbar-menubar {

margin-top: 10px; }

/* Move minimize/restore/close buttons to empty space */

1. TabsToolbar > .titlebar-buttonbox-container {

display: block; position: absolute; top: 17px; right: 1px; }

1. sidebar-box {

 min-width: 250px !important;

}`

Hello, I have read various post saying the profiles folder is %APPDATA%\Thunderbird\Profiles\ but on my side I have many folder, and it can explain why when I use a backup tool, I loose all my e-mail. I have - C:\Users\Me\AppData\Local\Thunderbird\Profiles - C:\Users\Me\AppData\Roaming\Thunderbird\Profiles - C:\Users\Me\Administrateur\Application Data\Thunderbird\Profiles

And how to have only one ? I have tried to edit setting to use only C:\Users\Me\AppData\Roaming\Thunderbird\Profiles but the application refuse it.

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 .

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 upgraded my PC, having backed up everything on Carbonite. On installing Thunderbird I cannot get it to recgnise and use my original Thunderbird profile downloaded from Carbonite. Peter Millar
