Suggested January 2024 How To Enable Strict Site Isolation In Chrome

One way to increase security in the Google Chrome web browser is to enable strict site isolation, which causes each page renderer process to contain pages from only a single site at a time, effectively placing them in a per-site sandbox.

Theoretically this could help to mitigate against certain security risks, like those posed by Meltdown and Spectre threats, but it should not be considered a replacement for simply keeping the Chrome web browser up to date with latest versions which often include various security patches.

Strict site isolation is considered a “highly experimental” security mode, and while it’s easy to turn on in Google Chrome it is not without some potential drawbacks, mostly related to resource usage.

How to Enable Site Isolation in Google Chrome

You can enable Strict Site Isolation in Google Chrome for Mac OS, Windows, Linux, Chrome OS, and Android. Here’s how:

Open the Google Chrome browser if you have not done so already

In the URL address bar, enter the following:


Once Chrome relaunches the Site Isolation feature will be enabled, and each unique website should be placed into its own Chrome process sandbox.

“Highly experimental security mode that ensures each renderer process contains pages from at most one site. In this mode, out of process frames will be used whenever an iframe is cross site”

However, a much more detailed explanation of Site Isolation is outlined on the Chromium site as follows:

Site Isolation is an experimental security feature in Chrome that offers additional protection against some types of security bugs.  It makes it harder for untrusted websites to access or steal information from your accounts on other websites.

Websites typically cannot access each other’s data inside the browser, thanks to code that enforces the Same Origin Policy.  Occasionally, security bugs are found in this code and malicious websites may try to bypass these rules to attack other websites.  The Chrome team aims to fix such bugs as quickly as possible.

Site Isolation offers a second line of defense to make such attacks less likely to succeed.  It ensures that pages from different websites are always put into different processes, each running in a sandbox that limits what the process is allowed to do.  It also blocks the process from receiving certain types of sensitive documents from other sites.  As a result, a malicious website will find it more difficult to steal data from other sites, even if it can break some of the rules in its own process.

What’s the drawback with enabling Site Isolation in Chrome?

Perhaps the most notable drawback is that enabling this feature can lead to increased memory and resource usage by Chrome, particularly if you use and maintain a lot of tabs and windows opened concurrently.

Because it’s experimental, there could be some other issues with the feature, but in testing with several dozen unique tabs open, the most notable difference is simply an increase in memory usage of various Chrome Helper tasks.

Chrome acknowledges that certain developer tools won’t function as expected as well, but that should impact fewer casual users.

If interested, you can read more about Site Isolation in Chrome by reviewing this Chromium page on the topic, and you can find many other Chrome tips here if you’re interested in some other interesting features and capabilities of the cross-platform web browser.

Whether you enable Site Isolation in Chrome or not, for optimal security don’t forget to regularly update your web browser software when updates become available.

How Researchers In A Simulated Moon Habitat Survived Extreme Isolation

For two space architects who spent two months in a remote Arctic habitat to simulate lunar exploration, getting personal and spending time on leisure helped keep them happier and pass the time quicker, according to a new study.

The study, published last month in Acta Astronautica, found that the two architects had an increasing desire for social connection over the course of the experiment, a 61-day mission in a small capsule-like habitat in Northern Greenland. The shelter, which they designed, is an egg-shaped pod that collapses using origami folds to become portable. Their only access to the outside world was a satellite phone limited to 160-character messages. 

They didn’t increasingly feel more resigned, however, as might be expected. The voluntary social isolation that explorers deal with in spaceflight, typically with a known end date, may impact people differently than the isolation some experience in day-to-day life. 

 “Our research shows that being socially isolated and confined in an extreme environment when you are motivated to achieve a goal…might have fewer negative consequences compared with other episodes of social isolation and social exclusion,” says Luca Pancani, a social psychologist at the University of Milano-Bicocca in Italy and an author on the paper.

For the purposes of simulating a longer space mission, two participants is too few people to be realistic, says Peter Suedfeld, a professor emeritus of psychology at the University of British Columbia who has studied how people respond to space and other isolated environments and wasn’t involved in the study. But the 61-day duration is more accurate than many other too-short experiments, because NASA plans to have a sustained presence on the moon.

“There’s a serious question as to the validity of simulation studies,” Suedfeld says, because the conditions of space exploration can’t really be mimicked on the ground. Though he thinks there’s still a place for them in space research. Essentially no psychological research has been done on astronauts on the moon, so good simulations are useful in studying how people might react during real lunar missions.

The LUNARK’s Moon analog habitat, built by the two space architects who lived in it for 61 days. Riva et al.

In this experiment, the participants had to suit up for the cold whenever they left their small pod to collect ice for water or to film the area for a documentary.

As for the finding that time flew while the architects were having fun—or at least doing anything recreational—that has been well documented in other situations, he says. This happened while the architects watched films together or exercised.

The Chinese Space Agency is doing a lunar simulation as well, though it isn’t focused on the outside environment at all, Suedfeld says. By contrast, many other experiments have tried to simulate Martian conditions such as the Hi-seas project in Hawaii and Russia’s Mars 500 experiment, which was entirely indoors in Moscow.

Even though there were only two participants, the study was conceptually robust, says Valerie Olson, an environmental anthropologist at the University of California Irvine, who has authored a book on the culture of spaceflight and wasn’t involved with the work. It is a nice example of exploring the relationship between social and psychological factors, she says.

[Related: We could live in caves on the moon. What would that be like?]

For a long time, the psychological study of individual astronauts has been central to the study of human spaceflight. But in the last decade or two, more emphasis has been put on social psychology and more qualitative sciences, she says. In this case, the study analyzed the results of a regular, self-reported psychological questionnaire. It found that when the architects–who knew each other well prior to the mission–talked about personal matters, that seemed to lessen feelings of resignation and hopelessness while increasing their desire for social contact.

Olson has a general criticism for simulations in extreme or isolated environments. Psychological researchers are often interested in finding universal human traits—attributes and experiences that can be generalized for large groups of people. But humans are “both biological and cultural beings,” Olson says, who can’t be separated from their cultural upbringings. So how individuals will react to these extreme environments depends a lot on what they think of the environments to begin with. She’s curious about the participants’ backgrounds: “Two young Danish male architects—what are their attitudes and experiences about the Arctic or about coldness?” she says.

The Arctic is typically described by experts in this kind of research as “as being a place of isolation and extremity,” Olson says. But the Arctic is also home to many indigenous peoples—for them, what seems extreme to Western researchers is home, and what seems like isolation is just a smaller social circle. The barren, rugged, unforgiving landscape could feel alien to one group and comforting to another.

Astronauts, including those from the US and former Soviet Union, have held different attitudes about what was good and bad about their time in space and different values about what space means to them, Olson says. She’s interested in what emerging space agencies, especially in the global South will focus on—how different cultures will explore the questions of “what is loneliness, what is sociality, what is belonging?”

If humans are to thrive in space, they may need to give more merit to what the astronautics community calls the squishy stuff—how people feel and what is meaningful to them.

This story has been updated to clarify there have been no psychological studies of astronauts on the moon.
