Mozilla Firefox - Export your Bookmarks to HTML
Save your Chrome bookmarks to an HTML file which you can then import into another browser
Instructions
Click the 3 lines in the top right of the window and click Bookmarks
Click Manage Bookmarks
In the new window which opens, click Import and Backup
Then click Export Bookmarks to HTML
Choose a save location (OneDrive recommended) and a file name and click Save
You can then use the same method later to import the HTML file. Instead of Export you click Import and navigate to the save location.
It is recommended that you create an account in Chrome so you can sync your browser settings across any computer you use. This will save you having to export bookmarks manually.
