Switchy is an add-on for Firefox to better manage several profiles. This add-on allows the user to create Firefox profiles, rename, delete and open them just with a click.
By using Switchy, you can open more profiles at the same time: an important feature for those who are concerned about security and privacy. For instance, you can have a separate profile for Facebook and other social networks while browsing other websites or have a separate profile for Google so you are not always logged in.
Don’t we have some similar addons? There are other similar add-ons but Switchy has extra features. You can assign websites to be exclusive for particular profiles. This means that, when from profile X I try to open one of websites saved in a specific profile, Switchy allows me to “switch” to the correct profile with just 1 click. For example, if I open ‘Facebook’ from my default profile, Switchy immediately offers me the opportunity to open the correct profile where I am logged in on Facebook - which is nice!
