It does what it is supposed to do. The first couple of times I installed it it kept telling me the desktop version isn't installed. It is. I'm on MacOS Ventura, Firefox developer 113. I updated the Time Doctor desktop client and it works now.

I would recommend providing the minimum requirements in the 'about this extension' section. For the error message, instead of telling me the desktop client is not installed, specify which version needs to be installed.

Other than that, I'm glad to see this extension.
