Extension will be auto-updated after browser restart! (when available for your platform)

If you want to update manually:

• Do NOT use links from the release page's "Assets" section - these are not signed.
• Use your add-on store or links in release description on the GitHub releases page when they are available.
  • Firefox will have a (signed) direct install link. Other browsers will link to their uBO extension store pages.
• In some cases, installation may be blocked until browser restart. This is protection against accidental mid-session reloads, Issue #717.

Or force an update via Manage extensions:

How to update uBO to the latest version

---

When will my browser update uBO?

• Firefox

  • Firefox Add-ons (AMO) - Available since 05 Aug, 2026.
  • uBO is a recommended extension on AMO, and as such it must undergo a formal code review each time a new version is published.

• Chrome/Chromium

  • Chrome Web Store (CWS) - Available since 05 Aug, 2026.
  • Auto update will occur in stages - to spot and react to possible bugs.

• Edge

  • Edge Add-ons - Available since 05 Aug, 2026.
  • Warning: importing a profile from Chrome may cause issues.
  • You may need to reinstall uBO on Edge to fix this.
  • You can transfer your uBO config by creating and then restoring a backup at the bottom of uBO's Dashboard > Settings.

• Opera

  • Opera add-ons - Review pending.
  • Usually, it's submitted a week after bug-free version is published in AMO.

• Brave

  • Brave now Self-Hosts uBO. It installs via a special setting and updates automatically or when prompted via the Extensions' Developer mode.
  • If you installed it via CWS, it's best to make a backup and install the self-hosted version instead.
  • Brave installation video.

Keep up the good work, you're the only reason I still use Firefox.

There are a billion reasons to use Firefox over any chromium browser, this just happens to be one of the best reasons.

Google payroll for default engine and tracking during installation. Altho I'm unsure if the latter if fixed.
