Open the profile folder file prefs.js in a text editor, with TB closed. Are the account details missing? If so, are there files like prefs-1.js, prefs-2.js,...?

hi, yes all files present, profile seems fully intact

i think i might just bite the bullet and move away from beta and go back to esr and just set all my accounts/pefs back up

but worrying this can happen

You should make regular profile backups anyway, or at least of the prefs.js file.

Rename the current (corrupted) prefs.js to prefs.old, rename the newest prefs-N.js to prefs.js, restart TB, and see if the original setup is displayed.

Is your full version number 128.4.3?

I've just finished installing esr and this will now be my goto backup strategy :)

Hi,

I've installed esr and started redoing all my config slowly :)

I tried your advice and...

1) installed thunderbird beta on another pc

2) copied over my old thunderbird folder from appdata/roaming to same location on pc were i installed the beta

3) changed the prefs-2.js folder to prefs js, (noticed it was about 80k, whilst the original prefs.js was quite small)

4) started thunderbird using p option and chose the my faulty "beta profile"

Unfortunantly result is the same, new setup account "wizard"

Postitive side is having to setup from scratch, although a pain, has resulted in a lot faster smoother thunderbird experience, so something good came out of it

I will follow your advice now and make a backup of the profiles folder occasionally

Is your full version number 128.4.3?

hi, always been running the latest beta as/when it came out, not sure what version i was running when it crashed since i have removed it and replaced it with esr
