Helium Browser Keeps Logging You Out of Google — Here Is How to Fix It

Helium Browser‘s aggressive cookie restrictions are automatically signing users out of Google accounts — including Gmail, Google Drive, and YouTube — often after every browser restart or brief period of inactivity.

The privacy-focused browser, built on a hardened Chromium fork, enforces strict cookie and site data controls that conflict with Google’s session authentication requirements.

Why It Keeps Happening

Google flags Helium’s cookie-blocking behavior as anomalous, triggering a security warning that reads “This browser or app may not be secure” when users attempt to sign back in.

Users across Reddit’s r/browsers and r/HeliumBrowserHQ communities report the sign-outs occurring on every reboot or after minimal idle time, with reports stretching back several months and a notable spike in recent weeks.

The Fix

A Helium developer and company co-founder who goes by @uwukko on X offered a direct workaround: allow third-party cookies specifically for Google domains.

Users responding to the post said the fix resolved their sign-out loops immediately.

To apply it manually, navigate to `helium://settings/cookies` and add the following sites as third-party cookie exceptions:

– `google.com`
– `accounts.google.com`

That single adjustment stops Google from treating Helium as an untrusted client during session validation.

Still having trouble? Try signing in through a specific Google product domain — Gmail, Google Drive, or Google Keep, for example — rather than the main Google sign-in page.

Once one domain authenticates successfully, all linked Google services should log in automatically.

Windows Users: A Different Problem

Users running Helium on Windows who still experience sign-outs after applying the cookie fix likely have corrupted User Data, according to community reports.

In that case, a full uninstall and clean reinstall of the browser resolves the issue.

Don’t Expect Helium to Change This

Helium is a privacy-centric browser and its cookie isolation behavior reflects an intentional design choice, not a bug.

The browser’s developers are unlikely to soften those defaults to reduce friction with Google’s session requirements — users who want Google services to stay logged in will need to manage cookie exceptions manually.

Chromium, the open-source browser engine developed by Google that forms the base for browsers including Chrome, Edge, and Helium, supports granular per-site cookie controls, which is what the `helium://settings/cookies` workaround relies on.
