The idea is great, it worked great. It took me weeks to finetune everything and really think about what I would like to open in which container. Had a few problems with webshops opening in one container and the bank to pay in a different one. Also quite a few 'prove that you are who you say you are by clicking the link in your email' type of situations, which were opened in the wrong tabs. Everything in the end worked great! But then I had a problem with firefox and decided to refresh firefox. Normally not a problem, due to sync I have all my settings back within a few minutes. But every site was opening without containers. I waited and waited and waited and waited... Yeah, no link to sync. Bye bye weeks of work to get 12 containers work brilliantly.

Since one of the most important functions is completely missing... only 2* otherwise 5*
