Light Visual Bookmarks от Artem Markin

Light Visual Bookmarks turns the new tab page into a grid of your real Firefox bookmarks. There is no separate list to maintain: add, rename, move or delete a bookmark anywhere in Firefox and the grid follows, and changes made in the grid go straight to your bookmarks.

Features
- Folders open right in the grid, with a Back tile and a preview of what's inside.
- Drag and drop to reorder tiles or move them into a folder.
- Three tile styles: site icon, page screenshot or first letter only.
- Screenshots are taken on your computer and stored only in your browser. New bookmarks get one automatically.
- “Skip screenshots” for mail, banking and account pages: mark a single bookmark or a whole folder.
- Your own cover for any tile: drop an image file onto it.
- 3 to 10 tiles per row; any bookmarks folder can be the start page.
- Light and dark look that follows your Firefox appearance.
- Background: solid color, your own image or the Bing image of the day.
- “Add to bookmarks” in the page context menu, straight into any folder.
- Open a bookmark in a new tab, window or private window; open a whole folder at once; copy a link.
- Backup to a file: settings, screenshots, covers and background.
- English and Ukrainian interface.

How screenshots work
To take a screenshot, the page opens for a moment in a background window with your normal session, exactly as if you visited it, and closes once the shot is taken. Before a folder is captured you see a warning, so you can mark private pages first.

Privacy
- No accounts, no sign-up, no analytics. Nothing is sent to the developer.
- Access to page content is optional and requested only after you click to allow it. It is used for screenshots and high-quality site icons.
- Site icons come from the sites themselves. When a site's own icon can't be loaded, Google's icon service receives the domain name only, never the full address.
- bing.com is contacted only if you choose the Bing background.
