The one thing I really want Firefox Sync to sync is Containers, but it hasn't yet over many devices. Other than that one big thing, it ROCKS

Awesome extension. I have created for myself rules to keep known abusive search engines (Hello Google!) outside of my regular browsing. Although it may not save me from "all seeing eye", I have no plans to make their lives easier))

Also, I would be very glad if in upcoming versions you will introduce possibility to write own rules (pattern matching or something similar), since as of now I had to manually open every Google service I'm using and force it to separated container (and this is not taking in account Google's country specific TLDs).

Thanks!

Excellent user experience; excellent functionality.

Works better than I expected. I use it often for logging into a website using multiple accounts.

It would be useful to have an option to prevent other sites (than those which were assigned to the container) from opening in the container. Like the 'Facebook Container' extension does. If I click a link on facebook.com that directs to other site than facebook, it opens in default container.

Outstanding extension. Tools like this really put a lot of power in the hands of the user for protecting their privacy. It would be perfect if you could use it in private windows and reorder the container list too.

It'll be even greater if I can drag and reorder my containers

Really helpful especially for social media sites like Facebook or Discord

This is hands down one of the best browser features I've used! It helped me fully convert to using Firefox both for work and personal stuff.
