Web Browser telemetry - 2025 edition
Опубликованы результаты анализа сетевой активности при работе браузеров Firefox, Chrome, Safari, Edge, Opera, Brave, Yandex Browser, Ungoogled Chromium, Mullvad Browser, Vivaldi, Librewolf, Arc, Tor Browser, Kagi Orion, Pale Moon, Floorp, Zen, Waterfox и Thorium. Целью исследования была оценка трафика, связанного с отправкой браузерами служебных сетевых запросов, не связанных с обработкой контента, просматриваемого пользователем. Помимо передачи телеметрии подобные запросы используются для проверки наличия обновлений, загрузки списков блокировки вредоносного контента и фильтрации рекламы, формирования содержимого стартовой страницы.
При тестировании учитывались только запросы, отправленные свежеустановленными экземплярами браузеров, до какой-либо активности пользователя. Проверялись самые свежие версии браузеров, доступные на момент тестирования. Отсутствие служебной сетевой активности сразу после запуска зафиксировано только у браузеров Kagi Orion, Tor Browser, Pale Moon и Ungoogled Chromium (см. дополнение). Остальные браузеры так или иначе устанавливали сетевые соединения с внешними серверами, которые как минимум получали сведения об IP-адресе пользователя.
Отмечается, что ни один из отправляющих запросы браузеров не предоставил пользователю возможность отказаться от начальной отправки данных - многие браузеры позволяют в настройках отключить передачу телеметрии, но изменить эти настройки можно лишь после того, как данные переданы во время первого запуска.
Распределение браузеров по числу хостов, к которым отправлялись служебные запросы (в скобках показатель за 2021 год):

Ungoogled Chromium
The initial test for Ungoogled Chromium showed three connections being made, but that was a mistake on my side (due to the fact that Ungoogled Chromium is my default browser, I have a daemon that’s syncing my dotfiles, text editor and browser settings, etc), so the three connections were established because I had 2 extensions installed (uBlock Origin Lite and Chromium Web Store). The two google.com connections were established by the Chromium Web Store extension, and the raw.githubusercontent.com one was established by uBlock Origin Lite, to update its filters. To summarise, Ungoogled Chromium has no default connections whatsoever.

Дополнение: Для Ungoogled Chromium результаты тестирования пересмотрены. Данные об установке трёх соединений были ошибочными, так как автор исследования по недосмотру протестировал не чистый экземпляр, а вариант с отдельно установленными дополнениями uBlock Origin Lite и Chromium Web Store. Упомянутые в отчёте соединения к google.com и raw.githubusercontent.com были осуществлены указанными дополнениями, по умолчанию не используемыми в Ungoogled Chromium. После данной ошибки автор заново повторил тесты всех браузеров, но больше различий не выявлено.
