Linux, Thunderbird is already running but not responding error
I recently reinstalled Ubuntu Mate, and copied over my Thunderbird profile from my USB stick back to the .thunderbird directory under my home folder.
I then started Thunderbird and received the following error.
I first checked to see if Thunderbird was still running in the background by running top from the terminal, but couldn't see any Thunderbird processes running. I also ran the following command just to make sure.
I also restarted the machine, but the error still occurred when I tried to launch Thunderbird.
I then decided to check the permissions of the folders, and noticed they where owned by root.
I then opened my terminal and ran the following command and changed the permissions of the folders and files to my username.
with your own username
sudo chown -R username:username /home/username/.thunderbird/
I then started Thunderbird again and was able to access to emails again.
