Multiple copies of TB can run simultaneously

Post by ineuw »

This is a fresh post of the problem I reported in the past, just can't find the old post.

If I mistakenly click the icon twice, I get two copies of Thunderbird running. Is there a way to prevent this? (aside from clicking twice).

Delete the session.json file in the profile. Help -> Troubleshooting Information -> Show Folder will display your profile using Windows Explorer.

Thanks tanstaafl. Actually I had two files created with the same timestamp. One was session.json and the other sessionCheckpoints.json. Removed both, and everything is working fine.
