Normally I don't log-in to post comments or reviews since I fear tracking cookies and it's too inconvenient to open a private browsing window just to post my opinion. This add-on has changed everything.

It's been a real pain managing multiple accounts using a combination of private browsing and different browsers. There are very few features in any application that increase both convenience and security/privacy. This add-on is one of those features. Things like this are the reason I still prefer Firefox over other browsers.

I'm giving this add-on five stars even though I think Multi-Account containers is a rather dry name. Wouldn't Personas have sounded cooler?
