Each time we fire up our Web browser and read an online article or shop for something online, some record of that session is recorded and utilized to help webmasters tweak offerings for visitors. While this could work in a user’s favor--by offering more relevant online experiences to a given visitor--it could also go against. For example, depending on the frequency of your visits to a site the price of a certain article being sold online could be unfairly increased the the site operator discovers you’ve visited a given product page often.
Mozilla, the organization behind the popular Firefox browser, is working on a method to counter this possible intrusion in privacy, using a feature called ‘Containers’. Containers essentially segregates your browsing activities into silos or contexts, such as Personal, Work, Banking, Shopping etc. It’s something like Chrome’s incognito mode, but with the possibility of multiple instances.
As explained by Security Engineer Tanvi Vyas on the Mozilla blog, each of these contexts has its own cache, local database and cookie jar (in this case, cookies being the elements that browsers utilize to store information pertaining to websites visits.) Using these contexts, a user could for example log into their personal Gmail account in one tab, and their official Gmail account in another tab within the same browser with both operating side-by-side yet mutually exclusive of each other.
To make it easier to remember what identity the user is currently browsing in, each one will have a unique color glow on the top of the tab, as well as in the name of the tab as depicted on the right side of the address bar. There is also the regular default container that can be used for normal browsing, outside of these identity-defined containers.
This feature is as yet experimental, but you can try it out in the Nightly Firefox 50 build. Click the File entry in the top menu, then click the New Container Tab, then select the identity you want to browse in.
