ad tracking generally gotten worse (which generally is a good sign) after I adopted some measures: tab containers, firefox relay, ad block ultimate, fastfoward and jslibcache. Thank god to all these privacy enhancing technologies!

Foundational to how I use the web now. Augmented with the Smart Containers extension my sessions stay separated with a minimum of fuss.

We need this functionality on Android!

A useful extension to have multiple accounts in one profile and having option to limit sites only to a container is good for privacy. Hope sync with Firefox account better with time, right now some tabs forget what containers they were in during new install.
