How to sync bookmarks between Chrome and Firefox
Updated
Chrome and Firefox can't sync bookmarks with each other out of the box. Chrome sync connects copies of Chrome signed in to one Google Account, and Firefox Sync connects copies of Firefox signed in to one Mozilla account. For a one-time copy, import one browser's bookmarks into the other. For ongoing two-way sync, you need a third-party extension such as the open-source Floccus. Reading Rewind does something different: it collects both browsers' bookmarks into one library, one way, and never writes them back into either browser.
What Chrome sync and Firefox Sync actually do
Each browser's built-in sync only connects to the same browser on your other devices.
| Chrome sync | Firefox Sync | |
|---|---|---|
| Account | Google Account | Mozilla account |
| Syncs between | Chrome and Chrome | Firefox and Firefox |
| Bookmarks | ✓ | ✓ |
| Open tabs and history | ✓ When History and tabs is on | ✓ |
| Also syncs | Reading list, passwords, payment info, extensions, settings | Passwords, payment methods, add-ons, settings |
| Turn it on | More (⋮) > Settings > You and Google | Click Sign in in the toolbar, then choose data under Settings > Sync |

So if you use Chrome at work and Firefox at home, neither sync service will carry a bookmark from one to the other.
Your options compared
| Option | Direction | Keeps going? | What you need | Fits you if |
|---|---|---|---|---|
| One-time import | One way, once | ✗ | Nothing extra | You're switching browsers |
| Export and import files | Either way, by hand | ✗ | A bookmarks.html file | You sync a few times a year |
| Floccus (third-party extension) | Two-way or one-way, your choice | ✓ On an interval | A storage service, such as Google Drive, Dropbox, Nextcloud or WebDAV | You want the same bookmarks in both browsers |
| Reading Rewind | One way: both browsers into one library | ✓ About once a minute | A free account and the extension | You want one place to find everything, plus a reading list |
Option 1: Copy bookmarks once with an import
Moving for good, or just want a snapshot? A one-time import is built in.
From Chrome into Firefox:
- In Firefox, open menu > Settings. In the General panel, under Import browser data, click Import Data. Or open the Library (Ctrl+Shift+O) and choose Import and Backup > Import Data from Another Browser….
- In the Import Wizard, choose your Chrome profile and the data to import, then click Import, and then Done.
- Look for your Chrome bookmarks in the Firefox Bookmarks Toolbar, which may be hidden.
These steps follow Mozilla Support.
From Firefox into Chrome:
- Export your Firefox bookmarks to bookmarks.html.
- In Chrome, choose More (⋮) > Bookmarks and lists > Import bookmarks and settings, click Choose file, and pick the file (Chrome Help).
Imports add to what's already there. Do it twice and you'll have everything twice. The duplicate bookmarks guide shows how to clean up, or how to merge both exports into one file first.
Option 2: Two-way sync with a third-party extension
For bookmarks that stay the same in both browsers, you need an extension installed in each one that syncs through storage you control. Floccus is one free, open-source option. According to its website and project page:
- It works in Firefox, Chrome, Edge, Opera, Brave, Vivaldi and other browsers that support web extensions, but not Safari.
- It syncs your browser's real bookmarks, and you choose one-way or two-way sync, how often it runs, and which folder it covers.
- It stores the data in a service you pick: Nextcloud Bookmarks, Linkwarden, KaraKeep, Google Drive, Dropbox, a Git server, or any WebDAV server.
Reading Rewind isn't connected with Floccus, and this isn't a review. Two-way sync also carries deletions between browsers, so export a backup from each browser before you turn it on.
Option 3: Collect both browsers in Reading Rewind (one way)
Reading Rewind doesn't sync Chrome with Firefox. It collects the bookmarks from each browser into your Reading Rewind library, where you can browse, search and tidy them together. Nothing travels back: a bookmark you add in Chrome never appears in Firefox, and the extension never adds, edits or deletes bookmarks in either browser.
How it works:
- Create a free account and install the extension in each browser: Chrome, the recommended setup, and Firefox, which is in beta.
- Connect each browser with its own pairing link from Settings > Sync. Each link works once. Give each browser a Source name, such as "Work Chrome" or "Home Firefox". Each browser profile becomes its own source, listed under Bookmarks in the sidebar. One you don't name is called Chrome 1, Firefox 1 and so on.
- On connecting, the extension sends a full copy of that browser's bookmarks: titles, links and folders. After that, it sends changes about once a minute. To pause, untick Keep bookmark sync running automatically in the panel. Changes wait until you turn it back on.
- In Bookmarks, pick a source in the sidebar to see that browser's folders, in the same structure as in the browser. With no source picked, search covers titles and links across your whole library.
What else you get, and what to expect:
- Deleted bookmarks are kept for review. When you delete a bookmark in a browser, Reading Rewind keeps it and lists it under Deleted in Browser in the Cleanup Center.
- The Cleanup Center spots overlap. Duplicate URLs lists links saved in both browsers, or twice in one.
- Open tabs too. Sync open tabs in the panel sends every open tab from that browser to your library, once per click.
- A reading list on top. Click the toolbar button on any page to save it to Read Later, with a stored copy of the article text (images aren't stored).
- You decide what stays. In Settings > Sync, Disconnect stops a browser syncing and keeps its bookmarks. Delete Source removes that browser's bookmarks and folders from Reading Rewind, not from the browser.
- Firefox needs reconnecting after every restart. The beta isn't signed by Mozilla yet, so Firefox removes it when it closes. Until you load it again and reconnect, Firefox changes aren't collected. Bookmarks added in the meantime are picked up when you reconnect.
- Desktop only. There's no mobile app.
It's free to use today, with no credit card.
Which option should you pick?
- You're leaving one browser for the other: a one-time import.
- You want the same bookmarks bar in both browsers: a two-way sync extension such as Floccus, after taking a backup.
- You use both browsers and just want to find things: collect them in Reading Rewind and search one library.
- Both browsers are the same brand on different computers: Chrome sync or Firefox Sync. That's what they're built for.
FAQ
Can Chrome sync with Firefox?
No. Chrome sync works between Chrome browsers signed in to the same Google Account, and Firefox Sync works between Firefox browsers signed in to the same Mozilla account. Neither connects to the other.
Does Reading Rewind sync bookmarks between Chrome and Firefox?
No. It collects bookmarks from both into your Reading Rewind library, one way. It doesn't add Chrome bookmarks to Firefox or Firefox bookmarks to Chrome, and it never changes the bookmarks in your browsers.
Will deleting a bookmark in Reading Rewind delete it in my browser?
No. The extension only reads your browser's bookmarks. To remove a bookmark from a browser, delete it there.
Can I use Firefox Sync and Chrome sync at the same time?
Yes. They're separate services, so each keeps its own browser in step across your devices. They just don't share anything with each other.
What about Safari or Edge?
Floccus doesn't support Safari. Reading Rewind's extension is tested in Chrome, with Firefox in beta. Other Chromium browsers, such as Edge, can often load it but aren't officially supported. If you connect one, Reading Rewind lists it as a Chrome source.
