https://sizeof.cat/ claims about new possible telemetry connections made by UC

[megastallman]

Hi everyone!
I've recently ran across this article, https://sizeof.cat/post/web-browser-telemetry-2025-edition/#ungoogled-chromium claiming that this year Ungoogled Chromium started establishing 3 unsolicitated connections that it hasn't established before.

clients.l.google.com
raw.githubusercontent.com
clients2.google.com 

I haven't checked it myself, so I'm not posting a bug report. Just appreciating someone whose work we can benefit from.

I couldn't reproduce this, so I emailed the author asking for more info. I'll open a GitHub issue and try to fix it if I figure out if (and what) these requests are triggered by.

Edit: The blog post has been updated:

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 and I have updated the chart and its section with the actual data.

Phew! Good news, it is not our fault :)

fact that Ungoogled Chromium is my default browser

That is a good a mention from him :))

@megastallman Thanks for keeping an eye on ... things :)
