How do I edit my Thunderbird profile?


Valued Member
When I open Thunderbird to read or write emails there is a folder called Thunderbird containing a number of the program files. I don't know how I managed to get it there but I'm trying to get rid of it. I have edited my Thunderbird profile and removed the offending folder in all instances, but when I reboot my computer and go back into Thunderbird the offending file is still there.
I would be tremendously grateful if someone could advise me how to get rid of it.
Another recent problem is that of Thunderbird slowing to a crawl. I've done everything I can think of to overcome the problem but without success. None of the suggestions I have read have remedied the problem. My new computer running Windows 7 Home Premium 64 bit has inherited the problem from copying my profile from my XP computer to it. I would be very grateful if someone could help me with this problem, too.

I'm not quite sure what you're describing. Can you show us a screen shot? Use Snipping Tool to get a screen shot.

You could always nuke your Thunderbird profile and start from scratch.


You can nuke your profile by deleting the Thunderbird folder under AppData.

AppData is a hidden folder under your user account that stores information for programs. Firefox has it's own folder, as does Thunderbird, and many other programs.

To get your app data folder simple click start and type %appdata% into the start menu search bar then press enter.

After deleting the Thunderbird folder, TB will think it's freshly installed and prompt you to setup your email accounts.

Hi Big Dan

Thank you for your reply to my email. I must apologise for taking so long to reply but my wife's computer crashed on the weekend and we've been in one hell of a mess. We've just about recovered everything of importance by now.

I was sick to death of Thunderbird so I followed your advice and zapped the profile which left me with a clean slate. I don't care that I've wiped out a huge number of emails because they're more trouble than they're worth.

Thanks, once again, and as always your advice cuts straight to the chase.
