I have Thunderbird v. 102.15.1 installed. I do not want to update to v. 115.16.2. I have set HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Thunderbird\DisableAppUpdate = 1. This worked for several months. However yesterday when I turned my computer on, I found that Thunderbird had updated to v. 115.16.2. After a great deal of fruitless attempts to downdate it again, I finally restored all of my C: drive from a backup I'd fortunately made just the day before. That worked and brought back v. 102.

However when I turned my computer on this morning, I found that once again Thunderbird had updated to v. 115. When I go to Menu > Help > About Thunderbird, it shows a window saying "Updates disabled by your system administrator". Yet "disabled" or not, Thunderbird updates itself! (I don't know what "system administrator" means - it's my computer and I'm the "administrator".)

How can I keep Thunderbird from updating without my permission?

Today is the first day using your latest update of Thunderbird (128.2.3esr (64-bit)) and I have been experiencing problems. In certain conditions when I am either editing a new email or receiving email, an email in my Drafts folder is Sent without my clicking SEND. No record of the sending exists in the SENT folder but the intended recipient has received it. In a second problem, the Correspondent in a mailbox has been edited to that ALL the email in the mailbox shows that Correspondent being the sender. I claim you have bugs in this release.

Heads up for custom installs: running tbird and firefox on linux, I install both in my home directory for my own ease of updates and portability. I get releases from https://ftp.mozilla.org/pub/ in tarball formats which install in 30 seconds. I recently ran into a problem which I've not seen before. recent d/l of firefox-136.0.tar.xz for linux-x86_64. It crashed immediately with err 126. The ff.exe and ff.bin files were for ARM arch. This wasn't easy to locate and I think it was caught but anyone still headscratching may want to see if this is an issue - I had a good 136 on a laptop and overwrote bad install on desktop.

I use google search engine. Google is blocking my email account and wants personal identifying info to unblock. One solution recommended is to have my mail data transferred elsewhere. I want to use Thunderbird for my mail. On Thunderbird's download page for Windows 7, an error 404 comes up. Where is the download page? Thanks.

Hi - I have been looking for over 2 days. How do I import all my data (emails, addresses calendar) from Outlook to Thunderbird.

I have tried Import tool within Thunderbird - import from Outlook. I tried MailStore and was totally confused - the terminology was strange. I managed to make an archive - it took ages to find where it was and I still do not know the file extension.

No videos...nothing.

Thanks

I have updated Firefox from 115.16.1 to Firefox ESR because I use a Mac running OS 10.13.6. Is there a way, hopefully an easy way, to import all of the bookmarks and extensions I was previously using in 115.16.1 to ESR. Hope so. Thanks!

Windows 11 system; currently running 131.0.3 (64-bit).

Was offered the chance to update to 132.0 (About | Help) (I do not and will not ever allow automatic updates without user approval, and my profile is stored in an entirely separate folder structure well away from the insecure \users hierarchy). Did the usual click on the update button, showed 132.0 downloading, update button changed to "Restart to Update", clicked the button...

And the update failed. Help | About shows 131.0.3, and the "Restart to Update" button is still active.

Tried again with a full shutdown instead of using the update button, same result.

So how do I force this update to install?

I guess there was an update to Firefox today because everything about my browser was a mess! >:( I have always had the Honey and Pinterest pin it buttons on my toolbar, and they have worked just fine. Now that this nightmare "update" happened, they don't show anymore, even though they are enabled in my settings and all permissions are checked. I am NOT very techy, so please don't reply with a long technical response that requires me to spend an hour trying to fix it. The buttons showed before, so why not now?! Please help! I've cleared cache and cookies, cleared history, everything I can think of and nothing is working. :'( TIA

I *think* I've followed the instructions, but I am unsuccessful in moving Thunderbird Profile to new PC. I copied old profile to external drive. I opened Thunderbird on new PC and found Profile folder. I went up 3 levels and pasted old profile from external drive into folder on new PC. But my old data have not moved. When I go into new Thunderbird and choose "open profile folder", it shows me 3 files: the two that the system created in the new download, plus the old Profile that I pasted there. The new version of Thunderbird uses the "new download" profile as the default. What am I doing wrong? Thanx!

Hello,

today I have installed new OS and new Firefox.

Because I was syncing everything I thought after login everything will be same as before.

Before reinstaling OS I didnt export anything from Firefox. Now I have no bookmarks, no history, add-ons.

I do keep Lockwise on my iPhone and it connected somehow with my desktop browser so I have passwords in my browser now (thank god for that - otherwise I have no clue how they got there).

Is there a way I can restore Firefox (bookmarks and add-ons) to how it was yesterday?

I dont have firefox install elsewhere, just on my desktop.

Thanks a lot for help

Good morning,

We are seeing that the key "DisableAppUpdate" being set to TRUE in about:policies. Not sure why this setting is being set. The result of the setting is "Updates disabled by your organization". So we cannot manually update firefox and are not sure why the setting is being set.

We used Procmon to capture logs:

Line 5169544: "2:29:45.2062951 AM","firefox.exe","1720","RegEnumValue","HKLM\SOFTWARE\Policies\Mozilla\Firefox","SUCCESS","Index: 0, Name: DisableAppUpdate, Type: REG_DWORD, Length: 4, Data: 1" Line 5169546: "2:29:45.2063211 AM","firefox.exe","1720","RegEnumValue","HKLM\SOFTWARE\Policies\Mozilla\Firefox","SUCCESS","Index: 0, Name: DisableAppUpdate, Type: REG_DWORD, Length: 4, Data: 1" Line 5169547: "2:29:45.2063338 AM","firefox.exe","1720","RegQueryValue","HKLM\SOFTWARE\Policies\Mozilla\Firefox\DisableAppUpdate","SUCCESS","Type: REG_DWORD, Length: 4, Data: 1" Line 5169548: "2:29:45.2063563 AM","firefox.exe","1720","RegQueryValue","HKLM\SOFTWARE\Policies\Mozilla\Firefox\DisableAppUpdate","SUCCESS","Type: REG_DWORD, Length: 4, Data: 1"

Is there anything in Firefox that can trigger the setting of this key?

Hello,

So I have Thunderbird which came with my Mint 22 install. My issue is that I imported my contacts (cvs) from Outlook into my personal contact folder. However, when I try to compose an email it can't seem to find the person I'm looking to message. I set my personal folder as default but it still won't work. I love Thunderbird but if it's going to be a problem sending emails then it's useless to me. Can someone please help me with this.

Kind Regards,

Bruce

I tried to open Firefox and a message appeared: "Couldn't load XPCOM". I uninstalled the program with Revo Uninstaller Pro and downloaded the latest version. I selected Run as Administrator but there is a message that says "Windows cannot have access to the selected device, path or file. Maybe you don't have access rights". However, I do have access rights. I have checked it multiple times. How can I install Firefox and see it work properly? Thanks

Κατέβασα το Firefox Installer.exe και προσπαθώ να κάνω εγκατάσταση με το Run as Administrator διότι για κάποιον λόγο δεν με αφήνει διαφορετικά, αν και έχω δικαιώματα διαχειριστή. Μου βγάζει όμως ένα παράθυρο το 7-Zip και μου λέει "Δεν επιτρέπεται η πρόσβαση".

Is there software that will being me (more or less) up to date? I'm pretty much computer illiterate, so keeping it simple would be greatly appreciated. Buying a new iMac and transferring files is a last resort...

Ever since a few weeks ago, some of my add-ons as well as every new add-on I added after that are unavailable at the start of Firefox. I then have to click into the application menu, click on the warning message for that add-on and enable it again. Since this is quite tedious and frustrating, I tried looking online for any info. I tried updating everything, disabling and enabling manually and removed and re-added some if the add-ons that cause issues.

I am loath to set up a fresh profile or reset all add-ons as that would cost a lot of time to configure everything again. In hopes of a solution that avoids that I am asking here now.
