Have you ever exported your bookmarks, only for some of them to break when importing them again?
bookmarks.backup.mp4
Looking at you Firefox, only allowing HTML as a Bookmarks export format...
Well this is the extension for you - exports your bookmarks in a state-of-the-art format, and easily import them later safely.
Tech Used: HTML, CSS, JavaScript, WebExtensions API & Polyfill
This extension built off the WebExtensions API generates a tree of all your bookmarks & folders, allowing you to select which to export - additionally allowing you to import a bookmarks.json file previously generated by this extension.
Handling of extremely long bookmark titles along with a high amount of bookmarks/folders can be tedious, and a number of folders containing only other folders can be collapsed to save space.
Learning both the way Firefox exports bookmarks in raw HTML, and how to use the WebExtensions API & Polyfills to create a cross-browser extension was a great experience.
