Have not seen this posted here and I believe it is new. Tried it out yesterday and could be very useful and protect people from fake websites etc so I thought I would share.

FMHY SafeGuard is a browser extension that keeps you safe by checking websites against the latest filterlists from FMHY Filterlist. The extension categorizes websites as starred, safe, unsafe, or potentially dangerous, giving you peace of mind while browsing.

Key Features

Real-time Site Status: Instant feedback on whether a site is starred, safe, unsafe, or potentially unsafe, with visual toolbar icons.

Updated Filterlists: Utilizes the frequently updated FMHY filterlist to ensure protection from the latest unsafe domains.

Pop-up Alerts: Get easy-to-read pop-ups that inform you about the site status and allow further action.

I wanted to ask you how does such an extension make your browser more fingerprintable.

I'm still interested in an answer, but after looking at the code there's a (actually not so) surprising turn: this thing sinply cannot live without remotely loaded google fonts (at addon startup) for some fucking reason.

that technically shouldn't make you more fingerprintable, but the extension makes sure google is notified that you opened your browser.

I am not an expert so I would highly recommend looking into more credible sources but my guess would be, since this is most likely not a very popular add-on, any browser with it would stand out considerably more relative to not having it.

Typically its common for browsers that want to reduce fingerprinting (tor, mullvad etc) recommend not installing new addons as then you stand out from crowd.

I'd say, since there are so many alternative ways to get this filter list, even if its a marginal increase in fingerprinting, its not worth installing it as an add-on.

I am not an expert

If you were, you would know that a website has no way to see what extensions you have installed, unless those extensions modify the page in a way that JavaScript can detect.

Which is why I was super clear about not being one. Glad you were able to get the opportunity to say what another user already said a day before.

websites cannot look at the list of your addons. they have to detect the presence of each, which is mostly possible when the addon makes changes to the page content, or replaces browser APIs in certain ways.

Typically its common for browsers that want to reduce fingerprinting (tor, mullvad etc) recommend not installing new addons as then you stand out from crowd.

because if an addon does something that a website can detect, that'll make you stand out
