I'm porting Thunderbird from my W-10 PC to a new Mac. I tried some things and found help on the net. Heere are the steps I took:

WHAT DOESN'T WORK (but I did): Removed installed Profiles folder and saved on desktop. Transferred PC Profiles folder to same place in Mac.

Deleted PC folder from Mac. Replaced Mac Profiles folder had previously moved. Deleted installs.ini and profiles.ini Started Thunderbird which created new profiles in Profiles folder.

WHAT SHOULD WORK BUT DIDN'T (after above): Removed new contents of Profiles folder. Transferred contents of PC Profiles folder to Profiles folder on Mac. Got the following message: "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible."

What did I do wrong? Do I need to uninstall Thunderbird and reinstall? Would that solve problems?

Thank you.

The latest update of Thunderbird somehow made this message appear "This is an unsupported version of Thunderbird!!" (see attached picture). Is this a bug? I've checked the version on the homepage and it's the same that's running on my PC (Windows 11).

Automatic update on my Windows 10 desktop of the the new update 127.0.1 resulted in a version of Firefox that worked more or less for some web sites but was unable to reach others.'

Attempts to run Thunderbird 115.12.1 in Windows 11 have failed repeatedly with error message: Unable to log in at server. Probably wrong configuration, username or password.

I lost my previous PC due to an unrecoverable hard drive crash. My current email provider is AOL and I was using the Thunderbird email app prior to the crash. According to some of the O&A posed at this site, I may have to contact AOL directly for assistance.

Please advise what information I need from them to complete the installation. I know you guys are busy and I can receive current emails from AOL at this time so there is no need to rush on my account.

I like Thunderbird a lot.

Thank you. Bob Perry

Hi,

I have changed the provider of e-mail services. The old IMAP account is already expired (not reachable).

I wanted to copy the messages from the old account to the new one. Unfortunately, it turned out that some messages contents are missing* (not downloaded locally). I acknowledge there's nothing I can do anymore to get the message contents.

However, I would definitely want to keep the records of the messages — their subject, correspondents, date and time. Can I get the message list in any form (other than taking screenshots) from Thunderbird? How to do it?

I have tested (not to work): - Copying / moving the directory from the context menu to the new account has no effect. - Dragging the individual messages has no effect as well. - After entering the Offline mode (from `File` menu) those actions result it a prompt informing that messages are not downloaded. - I tried copy-pasting the .msf file, directory and directory.sdb for the IMAP directory (with not-downloaded messages) from "ImapMail" of the profile to the "Mail" (local folders) to see if that would work, but it unfortunately haven't. - The .msf files do not contain the data (subject, correspondents, datetime).

• all the messages in question have been opened in Thunderbird. Therefore I thought I have them all on my local drive. I haven't rushed to copy the messages, because I have backed up the Profile directory (including ImapMail). Perhaps after organizing the mails (i.e. moving to appropriate IMAP directories) the local copies were deleted, and new copies (in target IMAP directories) not downloaded (as I haven't opened them anymore).

I recently converted my POP accounts to iMap. One of my local folders was corrupted. I restored a backup copy of Thunderbird that had the emails in a local folder. By local folder, I mean a folder stored on my iMac and not subject to iMap services. What I would like to do is to export the local folder from the backup TB instance and import it to my "live" TB version. Is this possible?

Is it possible to install Firefox (or at least the profiles) onto an external SSD (i.e., not the C: drive)? If so, how?

Note: this is not about migration/backup/recovery of profiles. Nor is it about where files are downloaded by default.

Windows 11 is consuming nearly all of the C: drive. I badly need to get Firefox (and later Thunderbird) onto my E: drive. I further note that the installer gives no options whatsoever as to the destination drive.

Most of the help I've found on the web is clearly outdated.

Thanks. jt

I've read everything I could find here and all of that is about using an external drive as a backup. Most of the other help I've found on the web is clearly outdated.

Hi, hope someone can help please

By mistake I set up my 89 year old aunties TB using a Beta version. All of her emails are in that profile. I then installed the stable version but I'm told that the stable version is an older versions and can not import from the Beta.

Specifically the Beta version is 127.0b4 (64-bit) and the stable vesrion is 115.11.1 (64-bit).

Is there any way to recover the emails (and if possible the settings) from the Beta profile to the stable release

Thanks in anticipation

Trying to use my old profile on a fresh install.

After trying a few things I ended up with an error that the profile couldn't be loaded or was inaccessible.

So I did the following:

1) started the profile manager 2) removed all profiles 3) created a new profile 4) changed the name of the folder in the file system 5) copied my old profile folder to the same spot with the same name that the profile manager gave it

When I started thunderbird, I was just expecting it to load with my old profile.

Instead, I got the Account Setup screen.

I don't want to setup my email account, as I'm worried it will start downloading all my emails, and store them in who knows what profile. I could not see a way to start Thunderbird without it successfully connecting to an email server in this setup process.

Any suggestions for just getting mozilla to start and load my old profile please?

Question 1 - Is this a real version? (as dlsplayed in troubleshooting information) Question 2 - How can I upgrade to version 115,, or do I have to delete and start again? Sub question - if I have to delete what is the best method? I just spent a few days installing and then installing 5 gig of settings and mail from Windows 10; I would hate to do it again.

Tired of Apple mail, want to install Thunderbird 78.14.0 on my mac mini. Am running Yosemite 10.10.5.

I can see access to the files on this site but need an installer to load to system.

Am familiar with unix can work off a console but am not a programmer, wouldn't know one end of a compiler from the other.

Can you point me in the right direction?

I want to create a link in the bookmarks toolbar to easy check and update firefox In chrome I can do that with creating a bookmark to: chrome://settings/help In edge I can do that with creating a bookmark to: edge://settings/help I have search for, but cannot find the equivalent in firefox

i have an old win10 machine with a huge thunderbird profile - 37.9GB size / 75.2GB disk. i'd like to move it with Tools Export / Import to a new win11 machine.

on win10 i click thru tools > export > open profile folder

and in ...\thunderbird\profiles i select yhcc00j7.dan and export it to an external ssd.

it runs for hours and then a number of these appear: "Are you sure you want to copy with file without its properties? The file %2B...." has properties that can't be copied to the new location.... Type WDSEML file size 1.02KB....".

so i check "Do this for all current items" and hours later it finishes.

on win11 i click thru tools > import > import from another thunderbird profile > choose a profile and select the folder yhcc00j7.dan on the ssd and import everything > start

for a minute or so it says "importing .... 0%" but no new profile shows up in ...appdata\roaming\thunderbird\profiles\ and then "import failed unexpectedly" is displayed.

i've tried this twice. both machines have version 115.11.1 "esr update channel". what am i doing wrong?

I upgraded from 126.0.1 to 127 today. Upon update, all my windows are gone. The only way I could access them is to revert to an older profile backup and reinstall 126.0.1.

I tried exporting my session with Tab Session Manager in 126.0.1 and reopen them in 127, but that only restores the last tab of each window (oddly). The json clearly lists 3 windows each with multiple tabs. I tried copying the sessionstore-backups folder, but no dice.

Ive tried reinstalling firefox because i am not able to download anything with this browser. I thought freshly installing firefox would fix the issue and allow me to download but it didnt. I also am tried to download an addon/extension, and that automatically fails to download. How can i fix this?
