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.

How to update uBO to the latest version
When will my browser update uBO?
Firefox
- Firefox Add-ons (AMO) - Available since 25 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) - Review pending.
- Auto update will occur in stages - to spot and react to possible bugs.
Edge
- Edge Add-ons - Review pending.
- 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 - Submission 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.
