If you switched from Firefox to Google Chrome because of speed, try the new revamped Firefox Quantum, it not only blocks those annoying ads to load the page faster but also makes it a pleasure to surf the web.
Some of the features & benefits are:

  • Free!
  • The most powerful private browsing mode with added tracking protection.
  • Some ads have hidden trackers that follow you online. Rude. We know. That’s why our powerful tool stops them cold.
  • By blocking some ads and scripts that bog down browsing, pages load up to 44% faster. Now that’s a win-win.
  • Library: Save time! Find all your favorite content like Pocket saves, bookmarks, browsing history, screenshots and downloads in one spot.
  • Sync your devices: Seamlessly access passwords, bookmarks and more. Plus, use our Send Tabs feature to instantly share open tabs between desktop, mobile and tablet.

No other browser gives you so much control over your digital footprint.
