Tab Notes let you attach a short note to a web page. You can use them to remember why you opened a page, what you planned to do next, or any details you want to revisit later.

Notes stay connected to the page’s URL. When you return to that page, your note reappears automatically.

How notes behave

Tab Notes are connected to a page’s URL and maintain this association until you delete them. Here’s what that means:

• If you navigate within the same page (for example, by clicking a link that jumps to a section on the same page), the note icon stays.
• If you navigate to a different URL in the same tab, the note icon disappears.
• If you come back later, the note icon reappears when you:
  • Reopen a closed tab that loads a URL that has a tab note
  • Open the page again from History that has a tab note
  • Restart Firefox and return to a page that has a tab note

Known limitations

• Notes work only on pages that start with http:// or https://.
• Notes are limited to 1,000 characters.
• Notes created in a private window will be visible in a normal window (and vice versa).
• Notes are not searchable from the address bar.
• Some websites that use single-page navigation may not update notes correctly.
