Good evening, I would like to uninstall and reinstall Thunderbird, which I have been using for years, but recently it has been showing some issues like losing passwords that I have to re-enter during certain restarts, or I have 5 addresses and my email displayed at each address but no longer in "Incoming Mail". How can I backup the hundreds of messages that I have in archive? How do I completely uninstall Thunderbird? How do I properly reinstall it? How do I install my archived emails? Thank you and happy new year!

Hello everyone;

If you reinstall Thunderbird and then restore your old profile, you will encounter the same errors as before!
I suggest using Mozbackup (Tutorial) to back up your current profile by unchecking the 2 boxes highlighted in red to restore it without your passwords and general preferences that seemed to be causing problems.

Then I suggest making a clean and complete uninstallation of Thunderbird, including its hidden files such as the profile, and then reinstalling it via this link, and finally restoring the backup you made without the passwords that you will need to re-enter, and your general preferences, and in principle, you should have a clean email client with the history of your address book and emails...

See you soon

Hello,
Thank you for your help.
I recorded MozBackup by unchecking "Preferences" and "Passwords".
I also installed "Revo Uninstaller" but... I can't find the Thunderbird icon! Neither in Revo, nor in "Programs and Features", nor by browsing through "C:" for the installed programs!!!
Where is this software hidden, how can I find it, and how do I uninstall it?

Thank you for a little big apprentice. I've had a few problems with Thunder, had everything uninstalled, and I'm not sure yet if I will follow up on it or not; it deserves some thought. Thanks to users like you for shedding more light on the situation... Good evening.

My problem seems to be solved. Thank you very much.

"Where is this software hidden, how to find it and how to uninstall it?
"

- Open the Control Panel through the "Start" menu
- click on the "Uninstall a program" link in the "Programs" section.
- Locate "Mozilla Thunderbird" in the displayed list and click on "Uninstall/Change" or "Uninstall".

Then clean the registry with CCleaner here:

before reinstalling Thunderbird.

"I didn't understand everything"! I made a backup with MozBackup and Thunderbird completely disappeared.
I reinstalled it. It reinstalled itself, of course, with all its flaws.
I will now try to uninstall it properly, especially by removing the profiles.

Hello,
I uninstalled Thunderbird with "Revo Uninstaller." At the end of the first cleaning, I clicked on "Scan" to apparently remove all the files that were not deleted by the first uninstallation. I then deleted all these new files found by the scan.
Then I reinstalled "Thunderbird," which installed... just like before with all its flaws!
What did I forget to do? Thank you.

Personally, I proceed as already indicated here:
https://forums.commentcamarche.net/forum/affich-35108527-desinstaller-completement-et-reinstaller-thunderbird#9
by performing error corrections with CCleaner > Registry, before reinstalling.
See the tutorial here:

Hello Abel,
I'm replying a bit late because, due to my schedule, I put my Thunderbird reinstallation on hold as it wasn't going well. You need to have a bit of free time, be careful, we're always at the mercy of a crash!!!
I resumed this reinstallation this weekend, following all your advice as best as I could.
I backed up all the data on my PC, including of course Thunderbird with MozBackup, UNCHECKING "GENERAL PREFERENCES" AND "PASSWORD".
Then I completely uninstalled Thunderbird using "Revo Uninstaller" (after that, there were no folders or files left in C: Program Files (x86), C:Programs, C:Users Admin AppData Roaming).
I reinstalled the latest version of Thunderbird software.
When I restarted, Thunderbird opened "clean" with no trace of the previous installation.
I then restored the MozBackup backup.
I found all my emails…but my addresses were also present as well as MY ERRORS: passwords don’t always stay in memory, and incoming mail is saved in the folders of each address without being grouped in "Inbox".
I don’t see where the solution to my problems might be? Maybe the MozBackup backup could be modified by unchecking certain boxes? In "Unknown files", at the bottom right of the window, might there be something to change? Is there another method?
For now, I'm just doing what I did before, checking my emails address by address, re-entering my passwords when Thunderbird asks for them, and occasionally sending a test message to my 7 addresses.
Thank you for your patience.
Have a nice day.

Hello,
You need to save your profile before uninstalling.
What system are you working on?

Good evening,
I work on Windows 7.
I have backed up Thunderbird C:\User\Admin\AppData\Roaming\Thunderbird and made a "Copy – paste" of the "Thunderbird" folder. Can errors in this folder be recorded and reappear after reinstallation?
I have also backed up using Mozilla Backup. Same question: Can errors be recorded in this backup and reappear after reinstallation?
Thank you for your help.
And best wishes for 2018!

@jmarion3: I had no idea that MozBackup also worked for Thunderbird.

A big thank you to you.

I also allow myself this:

Then I suggest you do a clean and complete uninstallation of Thunderbird, including its hidden files such as the profile

Well spotted!
Personally, I would use Revo Uninstaller: https://www.commentcamarche.net/telecharger/utilitaires/19405-revo-uninstaller/

And I would check that everything has been properly deleted, especially the profile.

How and where can I check that the profile is properly deleted?

Hello,
I have the same problem. I can't uninstall TB. I've tried using Revo, but nothing works; the old version reappears when I reinstall it. Is there a software that would completely uninstall TB?
Thank you in advance
