No FireFox icon on desktop. How do I access the search engine? I DO have the icon for Adobe Acrobat, which I got for FREE at Firefox. When clicked on only gives Adobe site.

I migrated one mac, which was intel based, to another, which is M4. It all went fine. I have the same versions of OS and Thunderbird on each, before the migration. The new machine is a 2025 Mac Studio. The old machine is a 2018 Mac Mini, 6 core Intel Core.15

On the old machine in Thunderbird, under my user, all my files are listed. On the new machine, files are not listed.

I saw a lot of information/suggestions to replace the Profile folder under: USER/Library/Thunderbird/Profiles And I copied it straight over from the old machine, with negative results.

I did notice that under profiles, it continues: m8mojurw.default-esr/Mail/Local Folders/ where there are some other goodies, some of which are "documents".

however, on the new machine, those same files are there, except they are "unix executable files"

I have migrated many times over the years and this hasn't happened.

I have done all of the suggestions I found so far, such as the Profile copy/past, reinstalled Thunderbird from scratch, looked thru comparisons of the Account Settings....

Oh, a couple more things:

If I look under my user and go to "Account settings" then "copies & folders" to looks different on the 2 machines. The old machine has: a check next to "Place a copy in" and under that a dot for "Sent folder on:" and my user name. On the new machine there is: "Place a copy in" and I cannot write into the "sent folder on" space, I can only select Choose and Account -> Local files as if the user doesn't exist (?) Thanks

Now that Thunderbird is delivered in .xz archives, not .bz2, the Linux system install instructions need updating. The extract command in Step 3 should be:

tar xJf thunderbird-*.tar.xz

note the upper-case J instead of lower-case which is used for .bz2

Hi, I've successfully downloaded and installed Firefox on my HP laptop with Windows 10 and now attempting to download and install the Thunderbird email client. On Thunderbird.net when I click the Download button, the Donation Page pops up (and I made a donation) then closed that window. I'm then on the Thank You page but there is no prompt to install, so just stuck on the Thank You page. Thunderbird is not appearing in my downloads file. Can you please help?

Madam/Sir

Please let me know if Firefox VPN is now made available for installation for Indian subscribers.

I am aware that Firefox may not have a server in India,as per our laws.

            Thanking You,

               Viraj

I've noticed that I've got both the 32 bit (../Program Files (86)/..) and 64 bit versions (../Program Files/..) of Firefox installed on my pc. I didn't install both and both appear to be the current version. Is this normal behaviour? Only one instance appears in add/remove programs, but if I go to default apps, Firefox appears twice (presumably the 32 & 64 bit versions). If this is not normal, does anyone have a suggestion as to how to remove the 32 bit version without damaging the 64 bit one?

I am a very long term Thunderbird user with gigabytes of historical emails w/attachments currently running esr 115 on my primary Windows 11 (upgraded from Windows 7 to Windows 10 to Windows 11) workstation. I need to migrate to a newer host which also runs Windows 11, so I installed release 144 over the weekend to get prepared for the migration. I know that the basic rule is that the From and To Thunderbird apps must be running the same version, but out of an abundance of caution, I would like to do that at the version of the production system which is on ESR at version 128.5.2. The download page is only offering a 140.something on the esr channel. Is there anyway to get 128.5.2 to accomplish the migration?

I am attempting to install Thunderbird on a new laptop and move personal folders from old to new PC. The installation process finds my email address and ISP information but fails with incorrect password.

Steps - 1. enter user name 2. enter email address 3. install finds correct ISP information 4. accept ISP information without changes 5. enter email password 6. process popup say incorrect user name, ISP info or password 7. login to ATT.NET successfully which indicates to me that the userid and password are correct for email account.

what other information could I supply to assist with problem resolution? I do not know what to do next.

Thank you, Neal

Today when I logged onto my MacBook I found that my Thunderbird desktop application is corrupt. When I attempt to open it states "You can’t open the application “Thunderbird” because it may be damaged or incomplete." Screen shots included.

I last used TB with no issues on Oct 27th.

I have over 20 years of TB emails that I do not want to loose.

I have backed up my profiles folders (there are 3) from >Go>Library>Thunderbird>Profiles

My first question is that I thought there were multiple locations of profiles. One for local. But I can only find the above profile.

My second question is how to I go about re-installing? Should I remove the corrupt application first and and then reinstall? What steps should I take?

Thank you!

Would like to test nightly builds of Firefox - how best to get started?

I am a user of Ubuntu and interested in testing the Firefox Nightly via snapstore.

Any pointers helpful.

The pc is a new Dell 8960 running windows 11 home. I installed t-bird from the microsoft store ver 128.5.2. I needed to do a system restore and when it was done Thunderbird.exe was gone. The link that I used to open it went to c:\users\username\thunderbird.exe but there was nothing there named Thunderbird after the restore.

I found Thunderbird at "C:\Program Files\WindowsApps\MozillaThunderbird.MZLA_128.5.2.0_x64__h5892qc0xkpca\VFS|ProgramFiles\MZLA Package Root\Thunderbird.exe" I made a shortcut to that but the response is "Windows cannot access the specified device, path, or file. you may not have the appropriate permission to access the item."

I do have a current copy of the profile.

I went into Thunderbird on my new PC, donated a few rand and went to "Install Thunderbird on Windows" - I get a Red circle with a red line through the middle with a comment "This content is blocked. Contact the site owner to fix this issue" What do I do now? Please help?

Thunderbird has turned into a scam. Each time I try to download it for windows it takes me back to the donation page. I am on my third donation but it never trys to install.

Yesterday I set up my Laptop with a new Windows 11 system from scratch. Then I installed Thunderbird from the Microsoft store and tried to paste the copied repository to the Profile Folder in %APPDATA%/Thunderbird/Profiles (as described here). And was astonished - there was none. All the folders as described in the Thunderbird settings (e.g. Local Folder, Profile Folder etc) are still descibed within Thunderbird to be there - but werent. When I clicked on "Open Folder" in the "Troubleshooting Information" - Page - I got an error, that it is not there).

I had to delete Thunderbird and learned by that, it iis installed as an App - it cannot be removed as programs are removed.

So I am left with the question: How to migrate the repository of Thunderbird is installed as App from the Microsoft Store? Where are the data persisted?

I'm trying to switch from Thunderbird ESR (140.8.0esr) to release (148.0). Following the Mozilla support recommendation I'm running the 148.0 setup and trying to install it to the same directory. While doing so I'm asked to restart the computer. After doing so I'm required to restart setup but continuously asked to reboot the computer. is there a zip version of the installation? if not How to overcome the restart issue?
