Does replacing chrome User Data with my own - works without leaving any trace behind? Where else chrome writes data outside of User Data folder?

I used to start office work by removing chrome User Data, replacing it with my own User Data copied from my external drive, saving the original User Data to other folder.

Before leaving in the evening, I will take back my own User Data, and bring back the original User Data where it is originally saved.

Is this process advisable?

Would I be safe this way or if not, where else does chrome save data outside of User Data folder in AppData?

Also, how is the process in Mozilla Firefox?
