How to import bookmarks into Firefox

Updated 18 October 2026

For a bookmarks HTML file, open the Library (Ctrl+Shift+O, or Cmd+Shift+O on a Mac), click Import and Backup > Import Bookmarks from HTML… and pick the file. Firefox adds the bookmarks to the ones you have, inside the Bookmarks Menu folder, which is why they don’t appear on the toolbar.

Pick the right import

Import an HTML file

1. Export the file from the other browser first: Chrome, Edge, Safari.
2. In Firefox, open the Library with the shortcut, or the menu button > Bookmarks > Manage bookmarks.
3. Click Import and Backup > Import Bookmarks from HTML…, select the file and click Open.

The other browser’s bookmarks bar arrives as an ordinary folder inside Bookmarks Menu (from Chrome it’s called Bookmarks bar). To put those links on your toolbar, open that folder in the Library, press Ctrl+A (Cmd+A on a Mac) and drag the selection onto Bookmarks Toolbar in the left pane.

Import from another browser on this computer

1. Click the menu button > Settings. On the Account and sync page (General in older versions), click Import Data under Import browser data. The Library’s Import Data from Another Browser… opens the same wizard.
2. Choose the browser and its profile. The wizard knows Chrome, Edge, Brave, Opera, Vivaldi and Chromium on every system, Opera GX on Windows and Mac, and Safari on a Mac.
3. Click the + button to choose the data, then Import. Enter your computer’s password if asked, then click Done.

The other browser’s bookmarks bar is added to the end of your Bookmarks Toolbar, which Firefox switches on. From Chrome-based browsers, Other bookmarks and Mobile bookmarks go into Other Bookmarks; Safari’s reading list becomes a Reading List (From Safari) folder in the Bookmarks Menu. A browser the wizard doesn’t list needs an HTML export. Step-by-step pages for Chrome, Edge, Safari, Opera.

Import a JSON or .jsonlz4 backup

Backups you make with Backup… end in .json; the automatic ones in your profile’s bookmarkbackups folder end in .jsonlz4.

• Add a .json backup to what you have: Settings > Import Data, choose Bookmarks from HTML file, set the file type to JSON File and pick the backup. Firefox puts each bookmark back in its original folder, so anything you still have shows up twice.
• Replace everything: Library > Import and Backup > Restore > Choose File… takes .json and .jsonlz4 files, after a warning that the backup replaces all your current bookmarks.
• Add a .jsonlz4 file: convert it with our free Firefox backup converter, then import the HTML file.

Import from an old Firefox profile

Firefox creates a profile for each installation, so a reinstall or update can leave your bookmarks in another one. Open about:profiles and use Launch profile in new browser on the others. When one has your bookmarks, Mozilla’s advice is to keep using it: click Set as default profile. To merge, export from that window and import the file into your main profile. With a profile folder copied from an old computer, restore or convert a file from its bookmarkbackups folder.

Imported bookmarks not showing?

• After an HTML import: look in Bookmarks Menu, in the Library or the Bookmarks sidebar (Ctrl+B).
• After a browser import: check the end of the Bookmarks Toolbar, where a full toolbar hides the rest behind the » button (Show more bookmarks), then Other Bookmarks. Mozilla’s help also mentions folders named after the browser, such as From Google Chrome.
• No toolbar at all: by default it shows only on new tabs. Showing the bookmarks toolbar covers the fixes.
• One link missing: type * and a space in the address bar, then part of its title.

Import not working?

• “The file doesn’t include any bookmark data”: the wizard found nothing it can read. Chrome’s own Bookmarks file is JSON in another layout and gets this message; convert it with the Chrome bookmarks JSON to HTML tool first.
• “Unsupported file type.”: Restore only takes JSON backups. Import HTML files with Import Bookmarks from HTML….
• No import options on a work computer: administrators can remove importing from other browsers with Mozilla’s DisableProfileImport policy.
• Everything twice: imports add to what you have, so run the file through our duplicate bookmark finder first.

On Android and iPhone

Firefox for Android is gaining Import from file for HTML files (three-dot menu > Bookmarks > three-dot menu > Import from file), which Mozilla calls experimental and is rolling out gradually. Without it, and on iPhone and iPad, import on a computer and let Firefox Sync carry the bookmarks over.
