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

I'm unsure if doing this will actually help me with a problem that I'm having, but I assume that it can't make it any worse, so my question is "Where can I download an (android) Firefox from?

For my puposes, I have the following requirements.

• My device has the Google play store (app), but I'd prefer to get a version of Firefox from a different location (because I doubt that what I want is in the Google play store). I know that Mozilla has sites that are specifically for hosting links to all of it's Firefoxes, so a link to one of those sub-sites would be ideal.
• The Firefox will need to be an ANDROID Firefox (because my device is an android tablet with an android OS).
• I don't know if Mozilla makes an (android) Firefox that is specifically for arm64-v8a android devices, but if they do, that would be preferred.
• EXTREMELY IMPORTANT = The Firefox will NEED to be able to use plugins. (I know that only some plugins will work in (android) Firefox.)
• I know that installing an (android) Firefox from anywhere except the Google play store (app) will mean that I'll (probably) need to manually visit the linked sub-site & get any updated versions from there. I accept that responsibility.

I am currently using (among other android web browsers) "Firefox beta", which I got from the Google play store a few days ago. I have a few logins (Google, Yahoo, & Facebook) already saved to that Firefox, but with Google, that was a pain in the (GUESS), & I'd prefer to avoid that if possible. Is there a way to "export" my (already installed) android Firefox beta's login information & then import that into a new side loaded (android) Firefox? If so, I'll need a link (or the instructions themselves) for how to do that.

I am trying to install Thunderbird on a computer with windows 10 pro but install gives a message cannot install require a minimum of windows 10 but I do have that. what can I do please. Regards Neil.

Probably my falt, the last version of Thunderbird got instaled on my PC. I do not like it, impossibility to read my message on the side of the screen, impossible to reorganise mails via there date after they reorganised themself throw sender order... So, I would like to go back on my old version, probably 143 or 144 ? Does anybody know how to do it without loosing all my data ? Thanks in advance... Pierre A. PS : Please forgive my english mistakes, beeing french does not have only advantages... ;-))

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.

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!

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?

this week I changed my Google Password and using Google, I can not access my Mozilla any longer to download it. It will download but when I want to finish it comes up with a screen as if Mozilla is broken. It lies within my Google new password I am sure, but I dont know how to fix it.

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?

Mozilla has announced that:

> Beginning with Firefox 144, the minimum supported Android version will increase to 8.0 (Oreo)

Where can we download version 143 to install on older devices (Android 5 to 7) from now on?

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,

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 professional developer and deliver Android rugged devices to professionals. I do not want to log on my personal Google account just to install Firefox via Google play. I am used to install via adb commands the apk packages. Why cannot we find the apk of Firefox easily to download ? thanks
