Can't Open Tab Session Manager

[Infernoflower1]

Hello, I'm trying to open Tab Session Manager, but every time I do, it flashes up a blank window and then closes. Please note that this doesn't happen in a new profile and I am using the same version in both profiles. How can I fix this?

That would be a question for the author of that extension. https://github.com/sienori/Tab-Session-Manager
