Russia’s mass missile, drone attack on Kyiv kills 5, injures 13. Russia launched a wave of missile and drone attacks on Kyiv and surrounding region overnight on June 23.

Russia seeks to advance along almost entire eastern front, Ukraine holding ground in Kursk Oblast, Syrskyi says. As of mid-June, Ukrainian defenders are fighting close to 695,000 Russian troops in Ukraine across a 1,200-kilometer (750-mile) front, Commander-in-Chief Oleksandr Syrskyi said.

Ukraine’s deep strikes cost Russia over $10 billion this year, Syrskyi says. This includes $1.3 billion in direct damage. The estimated cost-to-result ratio of Ukrainian deep strikes is 1:15, Commander-in-Chief Oleksandr Syrskyi told journalists on June 21.

Serhii Dobrovolskyi, a Ukrainian soldier who had been in Russian captivity since 2023, has died just a month after his release at the end of May as part of a 1000-for-1000 prisoner swap, an official from the soldier’s home region announced on June 21.

3 killed, 14 wounded as Russia strikes Ukrainian military training facility. “Unfortunately, there are some dead and wounded,” the statement read. The Ground Forces said that greater personnel losses were avoided thanks to the timely security measures taken when the air raid alert was issued.

Russia launched two Iskander-M or North Korean KN-23 ballistic missiles, an S-300 anti-aircraft missile, and 47 Shahed-type attack drones and decoy drones against Ukraine overnight, primarily targeting Chernihiv Oblast, Ukraine’s Air Force reported.

Ukraine calls for an end to Iran’s nuclear program in wake of US strikes. Ukraine’s Foreign Ministry said on June 22 that Iran’s nuclear program must be dismantled to prevent it from threatening the Middle East or the wider world, following U.S. air strikes on Iranian nuclear facilities.

Ukraine evacuates 176 citizens, foreigners from Israel ahead of US strikes on Iran, Zelensky says. The foreign nationals evacuated by Ukraine included citizens of the U.S., Moldova, Latvia, Azerbaijan, and Estonia, President Volodymyr Zelensky said.

How can a site see what extensions you have?

One of the things I've seen mentioned before is that installing too many extensions can make you more unique, and thus have a negative influence on your fingerprint. This got me curious, how exactly do sites detect which extensions you have anyway? Can they outright read your list of extensions?

Furthermore, do all extensions make you more unique? I guess the answer would depend on the answer to the first question (surely, if they can just outright see your list, then the answer would be yes), but lets say you install something that seems rather innocuous, like Transparent Standalone Images, for example. Can a site see that this is installed / does it make your fingerprint more unique?

explanation

Web sites do not have any way to enumerate or query your installed extensions, and they cannot directly "see" the content scripts injected by extensions. However, some extensions do modify pages in a way that scripts in the page could recognize as being the work of a particular extension, assuming the owners of the site care to research and check for such things.

One particular issue is that an extension may insert a path into the document to a page or image in the extension itself. Firefox assigns a randomized UUID to the extension at install time, and the path uses this UUID. On the plus side, this may prevent the site from associating the URL with a specific extension. On the minus side, at least in theory, a site could detect this weird URL in the page and use that for fingerprinting. See: How to prevent fingerprinting via Add-on UUID?.

is there anything else that I should notice?

Thank you!

Web pages are not allowed to list your extensions. They can indirectly surmise you have certain extensions based on how your requests differ from expectations. For example, if they have advertisements, but your browser never actually makes any requests to load the images, CSS, JS or HTML for the advertisements, they can deduce you have an ad-blocker. That’s a datapoint they now have to ID you: “has an ad-blocker”

Now let’s say they have an ad they know AdBlockPlus allows, but uBlock Origin doesn’t. They see your browser doesn’t load that ad. Another datapoint: “Not using AdBlockPlus”.

Based on what requests go back and forth between your browser and their servers, they map out a unique fingerprint.
