Open the add-on's page and click Add to Firefox. Firefox keeps it up to date from there.
Open on addons.mozilla.orgFor Firefox on the desktop, version 140 or later, on Windows, macOS and Linux. Firefox for Android doesn't let extensions replace the new tab page, so it isn't offered there.
Open the add-on's page and click Add to Firefox. Firefox keeps it up to date from there.
Open on addons.mozilla.orgDownload the latest .xpi. Each one is signed by Mozilla and, from 0.4.1 on, it's the same file as on Firefox Add-ons. In Firefox, open about:addons, click the gear icon and choose Install Add-on From File.
About the home page: Quick Dial NG also sets itself as Firefox's home page, so the dial opens at start and from the Home button. Firefox asks once whether to keep this. To use another home page later, go to Firefox Settings › Home.
Quick Dial NG has its own add-on ID, so it starts empty. The import brings over your tiles in their exact grid cells (gaps included), folders, pictures, per-tile options, grid and style settings.
about:debugging#/runtime/this-firefox, find the original Quick Dial and click Inspect.allow pasting first. It saves quickdial-export.json to Downloads.quickdial-export.json.(async()=>{const a=(await browser.runtime.getBackgroundPage()).app;const l=document.createElement('a');l.href=URL.createObjectURL(new Blob([JSON.stringify({version:4,settings:a.settings,node:a.node})],{type:'application/json'}));l.download='quickdial-export.json';document.body.appendChild(l);l.click();})()
Each tile is linked to a bookmark in the Quick Dial folder by its bookmark ID, then by address (folders by name). Tiles without a match get a new bookmark, so an export also works in another Firefox profile or on another computer. Bookmarks already in the folder that the export doesn't mention stay and fill empty cells. Importing the same file twice creates nothing new.
Settings › Backup › Export backup saves tiles, pictures, settings and themes to one JSON file. Import it in another profile or on another computer the same way.
