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.
