Saving your favorite or frequently used shortcuts to the browser bookmark making it possible for you to navigate to them in seconds from anywhere in the browser. This is very convenient. However, some users said their Firefox bookmarks disappeared somehow; they want to get the bookmarks back but don’t know how to do.

What Is Bookmark?

The bookmark is an important feature in all modern web browsers including Mozilla Firefox, Google Chrome, Microsoft Edge (previously Internet Explorer), and more. According to Wikipedia, “a bookmark is a Uniform Resource Identifier that is stored for later retrieval in any of various storage formats”. In simple terms, the bookmark refers to a place where you can save URLs for later use. Saving web pages in a bookmark allows you to get quick access to them.

Firefox Bookmarks Disappeared

Bookmarks are used frequently; so correspondingly, there are lots of bookmark-related problems. Let’s just take Firefox as an example; you may run into these problems all of a sudden: Firefox bookmarks not showing, Firefox bookmarks toolbar not showing, Firefox bookmarks not working, etc. Considering so many people are complaining about Firefox bookmarks disappeared, I’ll discuss this issue and shows you what to do when that happens.

My Bookmarks Are Gone

Firefox bookmarks disappeared or missing may be a result of many factors: system crash, software issue, accidental deletion, virus attack, updating or downgrading Firefox, etc. But according to users’ feedback, the update of Firefox is the most possible cause for making bookmarks toolbar gone and Firefox bookmarks disappeared from toolbar.

There is a real case I found in the Mozilla Firefox Support Forum:

Firefox Bookmarks Location

Users are curious about the location of their Firefox bookmarks, so they are asking questions online, hoping to get an accurate answer.

  • Where are Firefox bookmarks stored?
  • Where does Firefox store bookmarks?
  • Where are my Firefox bookmarks?
  • And so on.

To figure out questions like these, you must know what a Firefox profile is and what it stores.

Firefox Profile: Where Your Bookmarks, Passwords, and Other Data Are Stored

Firefox (or any other web browsers) keeps your personal information including bookmarks in a set of files, which are called profiles. The Firefox profile is stored separately in a location from the Firefox program files. The default location of the Firefox profile on your PC is C:\Users\Username\AppData\Roaming\Mozilla\Firefox\Profiles\; that’s where your Firefox bookmarks are stored. It remains the same from PC to PC unless you change the Firefox bookmarks location manually.

Note: You can have more than one Firefox profile to contain a separate set of user information.
