I Left Google Chrome for Firefox—and Took My Browser Data With Me

Firefox can import key Chrome data without changing Chrome, but passwords, payment methods, extensions, and open tabs have important limits.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

You can move the main things you rely on in Chrome—bookmarks, browsing history, saved passwords, autofill data, and some compatible extensions—into Firefox. It is not a perfect clone of your Chrome setup: passwords and payment methods have operating-system limits, extensions may not match exactly, and open tabs need a little preparation. Firefox’s import does not delete Chrome data or change Chrome settings, so Chrome can stay installed while you make the switch.

What Firefox can bring over from Chrome

Firefox’s Import Data wizard lets you choose a Chrome profile and select which categories to import. Mozilla lists bookmarks, browsing history, saved passwords, extensions, and form autofill data among the supported categories. The available choices can depend on your platform and what Firefox detects. Mozilla’s import guide explains the wizard, while its Chrome-to-Firefox switching guide confirms that importing does not remove Chrome data or change Chrome settings.

  • Bookmarks: your saved sites move into Firefox; some may appear in the Bookmarks Toolbar, which can be hidden.
  • Browsing history: Firefox can import Chrome history.
  • Passwords: the method depends on your operating system; Windows and Linux users need a CSV workaround.
  • Form autofill: Firefox can import supported form data.
  • Extensions: Firefox can look for comparable add-ons, but it cannot guarantee a match for every Chrome extension or identical behavior.

“Everything” is best understood as the useful browser data Firefox can import—not every setting, open session, extension, or feature from Chrome.

Before you start: save open tabs and close Chrome

If you want to keep a record of tabs that are open in Chrome, bookmark them into a dedicated folder first. Mozilla recommends this because the import process does not promise to recreate your open-tab session. After saving the folder, close Chrome before starting Firefox’s guided switch process. Mozilla’s switching instructions cover both steps.

Import Chrome data into Firefox

  1. Install and open Firefox. The Import Tool may appear during first launch. If it does, you can use it there; otherwise, continue through Settings.
  2. Open the import wizard. In Firefox, go to Settings > General > Account and sync > Import Data. Labels and placement may vary by Firefox version, platform, or language. Mozilla also documents an alternate route through the Bookmarks Library: open the Library, choose Import and Backup, then select the import option.
  3. Choose Google Chrome. If Firefox finds more than one Chrome profile, select the profile whose data you want to bring over.
  4. Select data categories. Choose the items you want, such as bookmarks, history, autofill data, extensions, and passwords when that option is available.
  5. Run the import and select Done. Check Firefox’s bookmarks and other imported data afterward. If bookmarks seem missing, look in the Bookmarks Toolbar; it may simply be hidden.

For the current wizard details and alternate route, see Mozilla’s import-data instructions.

Passwords on Windows or Linux: export and import a CSV

Mozilla’s current instructions say automatic Chrome password import is unavailable on Windows and Linux. The documented workaround is to export passwords from Google Password Manager as a CSV file, then use the CSV password-import route in Firefox’s migration wizard. Follow Mozilla’s platform-specific directions in Import bookmarks and other data from Google Chrome.

A password CSV is sensitive: it contains credentials in a portable file, so treat it as exposed while it exists. Store it somewhere private, do not send or upload it, and remove it securely once Firefox has imported the passwords. Do not assume the export or import is automatic; complete the steps in Google Password Manager and Firefox’s wizard.

What does not transfer exactly

Chrome payment methods

Mozilla says Chrome payment methods are no longer importable to Firefox on Windows, attributing the change to Chrome’s encryption mechanism. This limitation is specific to the documented Windows guidance; do not count on payment details appearing in Firefox’s imported data. Mozilla’s Chrome import page has the current details.

Extensions

An imported Chrome extension is not necessarily installed as a working Firefox extension. Firefox looks for comparable add-ons, and a match may require you to complete a final installation step. Some Chrome extensions may have no Firefox equivalent, or may work differently. Review the offered add-ons and install only the ones you actually want. Mozilla describes this matching process in its Chrome import instructions.

Open tabs and other browser setup

Bookmark open Chrome tabs before switching if you need a recoverable list. The documented migration covers selected data categories, not a promise to reproduce every setting, session, or detail of your Chrome workflow.

Several Chrome profiles? Choose the right one

Chrome profiles keep browsing data separate. If Firefox offers more than one profile during import, choose the one containing the bookmarks, passwords, history, and autofill data you want. If important items are missing afterward, check whether you imported a different Chrome profile rather than repeating the process blindly.

Sync Firefox after the local import

The Chrome import moves selected data into Firefox on the device where you run the wizard. Firefox Sync is a separate, optional feature: configure it if you want Firefox data synchronized across your other devices. It is not required to import Chrome data. Mozilla’s Sync data guide explains the feature.

A quick post-import check

  • Open several imported bookmarks, including any in the Bookmarks Toolbar.
  • Search Firefox history for a site you recently visited in Chrome.
  • Check saved logins in Firefox, especially if you used the Windows or Linux CSV route.
  • Review imported or suggested extensions and finish installing any compatible add-ons you need.
  • If you use Firefox on other devices, configure Sync separately.
