Profile Switcher

Rated 1 out of 5 stars

I found it strange when I went to install and received this information: “This extension Will have permission to: Have FULL, unrestricted access to Thunderbird, and your COMPUTER”. Why does the extension need to fully access the computer?

This review is for a previous version of the add-on (2.6).
