If you're willing to try Firefox Nightly, check out the containers experiment: https://wiki.mozilla.org/Security/Contextual_Identity_Projec...

While everything still happens within a single profile, sites in different containers get different storage (cookies, localStorage, IndexedDB, etc.) and cannot see each other.

Cool.

I've been using a combination of NoScript,Self-destruction coockies,ublock and a personal vimperator script to wipe out all that nasty stuff when I close the window.

By the way firefox is pretty nasty by default and you must do a lot of hard work to evade tracking, in special by google:

Of course you must use custom fonts if you don't want to be tracked by google for every single webpage you enter.

I think I will play with containers for firefox when I try firefox 50. Something like a new container for every tab, I reckon It must be pretty easy with vimperator(or whatever plugin you like) to make .

Put your vimperator/penta/vimium/X to work for you. :)

That looks way more powerful than what Chrome is doing. I'll give it a try. Thanks for the suggestion

I think this is great, but is there going to be a simple "sign in" feature similar to Chrome? People just love having their bookmarks / toolbars / etc follow them wherever they go.

You can sign in to a Firefox Account to sync your bookmarks, passwords, history, etc.:

What's wrong with `firefox -P`?

Compared to Chrome profiles, it's much less usable in regard to launcher icons and window management. There are workarounds (system-specific), but none I saw worked as nice as Chrome's implementation.

Container tabs are (IMHO) better than Chrome profiles, because they don't require one to have a separate window just to open a single site.

You mean compared to just right clicking the top right corner in Chrome? A lot.

You can also run several profiles in parallel with the no-remote flag.

yes, this! I've tried so hard to like FF profiles, I really wish they'd make this better. I still refuse to go to Chrome, but I'm getting lost on these small features.

I use 'firefox.exe -p "test" -no-remote' to open a second window with a different profile. or do you require to have it in the same window ?
