Ungoogled Chromium 155.0.8059.39-1 ships, bringing the Google-free browser back in step with Chromium Stable
The all-platforms release tracks the latest Chromium Stable, inherits its two dozen-plus security fixes.
Ungoogled Chromium, the project that pulls Google out of Google's own browser, has published version 155.0.8059.39-1. It ships for all platforms this time around, which is a small but real win for the Windows and macOS crowd.
That last line matters. Recent months have seen Ungoogled Chromium releases go Linux-only more often than not. The 151 and 150 series were largely Linux builds, tagged by whoever happened to be free, Ahrotahn, networkException, wukko all take turns. So an all-platforms tag isn't nothing. It means Linux, Windows, and macOS are all in the box, and Ungoogled Chromium stays locked to the same Stable version Google shipped.
Keep in mind that Ungoogled Chromium isn't a privacy browser in the point-and-go sense. It's a drop-in replacement for Chromium that strips the Google glue away. Same vanilla look and feel. Then three tweaks, by design, that you have to switch on manually: remove the Google web service dependency, stay as vanilla as possible, and add the privacy or control options you actually want.
Here's the deal, and the tradeoffs
Binary pruning is how it strips pre-built Google libraries out and swaps in system-provided equivalents where it can. Domain substitution is the other half of the trick. Google's web domains get rewritten to fake ones ending in qjz9zk, which Ungoogled Chromium patches Chromium to block. If anything still tries to reach Google, you get an info bar. Not the friendliest thing in the world, but it works.
The tradeoffs are real though. Safe Browsing is off by default, with the project steering you toward uBlock Origin or uMatrix instead. Cookies clear on close unless you change that. Installing extensions from the Chrome Web Store takes manual workarounds. You buy control with convenience. For a lot of people that's worth it. For others, the friction is the dealbreaker.
Now the actual substance, since Ungoogled Chromium just tracks Chromium Stable: the real story here is Chromium 155. And that's fundamentally a security update, not a feature drop.
Google rolled Chromium 155.0.8059.39 to the Stable channel on 6 October 2026, two days before Ungoogled Chromium rewrapped it. Windows and Mac got .39 and .40. Linux got .39. Google's own release post lists 24 security fixes. Several are rated Critical.
Four of them are Critical use-after-free flaws. One lives in Chromecast (CVE-2026-106382). Another is in the Browser component, reported by Xinyang Ge. Two more, in Navigation and Track, are also by Xinyang Ge, but both are credited as "Anthropic, assisted by Claude."
Yep. Two Critical browser bugs, found by an Anthropic researcher, with Claude doing the heavy lifting. There's yet another entry attributed to OpenAI Codex Security. It's 2026, and a chunk of the security research feeding into your browser is now co-authored by language models. A little fitting, honestly, given Ungoogled Chromium's whole ethos is about transparency. The tool that strips Google out is being hardened by AI-augmented researchers.
Beyond the Criticals there's a pile of High-severity issues. Uninitialized resources in ANGLE. Type confusion in V8. Race conditions. Then proxy, WebGL, PDF, and media, the usual suspects, with bounties of $1,000 to $5,000 for the externally reported ones. Ungoogled Chromium users inherit the whole set, minus the browser's own independent calls to Safe Browsing to do it. Which is the entire point.
The cadence here is brisk. Ungoogled Chromium re-patches Chromium for every upstream Stable build, sometimes multiple times a month. July brought the 150 series. August was the 151 series, all-platforms and Linux-only builds scattered across the month. Now this 155 build, a couple days behind Stable.
And upstream Chrome is already nudging toward 156; Chrome for Android 156 reached a small slice of users on 7 October. So Ungoogled Chromium sits just a few days behind. By design. It's a mirror, not a fork with its own agenda.
The project itself is bigger than its release notes suggest. Roughly 27,900 stars and 1,300 forks on GitHub. 176 open issues. Five open pull requests. All under the permissive BSD-3-Clause license.
Grabbing it
If you want to try it, Ungoogled Chromium ships for essentially every desktop platform. Arch users hit the AUR. Debian folks use OBS. Ubuntu has the XtraDeb PPA. Fedora gets a COPR and, if you're really desperate, RPM Fusion. Gentoo, openSUSE, OpenMandriva, FreeBSD, and OpenBSD all have repos too.
Homebrew is probably the easiest path for macOS. Just brew install --cask Ungoogled Chromium. Flatpak is on Flathub if you want it sandboxed across distros. There are also third-party "contributor binaries," though the project explicitly warns those aren't reproducible and can't be guaranteed untampered. If you actually care about trust, build from source using the 155.0.8059.39-1 tag. It takes patience.

Honestly, this isn't a splash. There's no new feature to cheer about. But it's the thing that keeps privacy-focused Chromium users secure and Google-free between the bigger releases. Same browser, minus Google. That's been the promise since day one, and release 155.0.8059.39-1 keeps delivering on it.
