Run Firefox in a protected sandbox
Authored by: afingal on Feb 10, '11 08:49:37AM

I gather that this kind of sandbox does not address the main reason why I want to run a web browser in an isolated environment. That is to have separate instances of the web browser such that different sites can not access information from other sites. Web developers are using ever more sophisticated ways to track people and bypass the originally intended privacy standards which were supposed to be part of html (e.g. cookies only sent back to the same site.) You have to use something like virtual machines to prevent this. The only thing is that they are a lot less convenient to set up and use a lot more resources than the kind of sandbox in this hint.

The situation now is that, for example, if you are logged into Facebook in one tab and go to some other site in a second tab and there is an advertiser common to both sites, the second site can get and correlate information from your Facebook profile with what they have, including non-public information. Facebook allows you to choose items to keep private from other Facebook users but you can't hide anything from advertisers (or, more precisely, anyone using Facebook's developer tools.) I'm only picking on Facebook because they are such a popular site. Many other sites do the same sort of thing or worse.

Run Firefox in a protected sandbox

So basically, you want to run each tab as a separate sandbox.

This would tend to be possible: there's an extension for Windows that allows IE to run as the renderer inside each Firefox tab.

The same principles could apply for your purposes, substituting IE for a sandboxed Firefox instance.

Or you could run an ad blocker... just sayin'.
