I’m a fan of FOSS and reasonable privacy with data. I also often look for and install software on my computers for random tasks as they come up. Today, when I was looking to install an extension to Firefox called Wikipedia-EN that helps me search Wikipedia by highlighting a word, the Mozilla page for the extension states:
This add-on is not actively monitored for security by Mozilla. Make sure you trust it before installing.
As someone that is not educated in programming or perpetually current on tech news, what can I do to assess the safety of this and other software? Is there a site that transparently evaluates software and publishes its findings?
Both practically and theoretically, it might be impossible. It basically comes down to trusting trust. https://www.youtube.com/watch?v=SJ7lOus1FzQ
Mostly if you find an attached GitHub repository to the software, you can have a bit more trust in it than otherwise, it means that the developer is putting their cards on the table and not trying to hide something nefarious. Of course there are caveats to this but it’s a good start.
Running any software is inherently unsafe. It’s basically the computer equivalent of eating something given to by a stranger, and you just have to trust them that it’s good for you.
But we do it anyway, simply because we have to - not all of us are software devs with unlimited time on our hands.
It basically comes down to whether you trust the origin or not, as well as check the reviews/comments to gauge the reception of other users. If something fishy is going on, word spreads relatively fast.
Tip: While no means foolproof, if the software in question has a github repo, it adds a layer of trust, because that means anyone can review the source.
Even as a power user… You can’t.
And, in the 21st century, nothing on your computer is safe and private, least of all, browser extensions.
Even if an extension is safe today, with a tiny handful of notable exceptions, it will be”monetized”, or bought and sold to someone that will use it to install adware on your system, train their AI model, or steal your personal information.
There is no feasible defense to this for a layperson, other than absolute transparency in FOSS, and even that is under attack via flaws in the software supply chain.
The best a layperson can hope for is that major vendors care more about exclusivity and locking others out of their ecosystem, such that they are the only ones who have full control of your data (Apple, Google, Microsoft).
A lot of it comes down to trust. Scan downloads with antivirus. Decide how much you trust everything else. Err on the side of caution if you’re unsure.
In your example, the software you’re using seems fine to me. A simple addon with limited scope that hasn’t been updated in years, but has some good reviews.
That said, you don’t need this addon; go to your favourite Wikipedia front page, right click the search bar, and click “add keyword for this search”. If you enter keyword “wen”, you can search English Wikipedia by typing “wen <something>” in the search bar. Works for other websites too
Github releases can contain completely different code than the source code on there. Don’t trust them blindly like others might suggest. It’d be trivial for someone with bad intent to release FOSS software and include a virus. It happened to an important Linux tool not that long ago. Most code on Github is fine and most software is just out there to help you, but it’s good to he careful.
My personal process involves checking for things like “how many downloads does this have” and in the case of addons and apps “how many permissions does this ask”. Addon with a dozen downloads to change your Facebook theme that wants access to your entire browsing history? No thanks!
The biggest differentiator between virus and safe in my experience is “how legal is the thing I’m downloading”. Viruses, cracks, keygens, pay wall bypasses, that sort of stuff is full of bad shit, because whether or not there’s a virus in there, your antivirus will go off anyway and you’d assume it to be a false positive.
There are steps you can take to protect your computer, but generally “keep antivirus on”, “don’t pirate stuff”, and “when in doubt, click no” are generally good enough.
There’s a cool trick recent pro/education versions of Windows have where you can create an entirely temporary copy of Windows by simply right clicking an executable and clicking “run in sandbox” or something like that. This is great for trying out small programs that you don’t 100% trust but seem fine at a glance. Doesn’t work well for games, isn’t 100% bullet proof, but it’s an easy way to prevent unexpected infections. The only downside is that you need to get a Windows pro/education key somewhere (though those are not hard to come by). Really wish Microsoft would roll that out to home users.
