Thanks to the changes made to the engine and the UI, the browser is amazingly fast. The user interface of Firefox became more responsive and it also starts up noticeably faster. The engine renders web pages much faster than it ever did in the Gecko era. In addition, Firefox 67 will come with a major enhancement further made to the Quantum engine called WebRender, which will be enabled for a small group of users as of now.

How does the Refresh feature work?

All the personal information and Firefox settings related to your user profileare stored in the Profile folder. During the refresh Firefox process, a new folder is created to store all the important information.

However, keep in mind that add-ons you have installed manually are also stored in the Firefox profile folder, including extensions and themes. They will be removed. Add-ons stored in other locations, such as plugins, will not be removed but their settings will be reset. The system plugins you have manually disabled will be re-enabled.

  • Bookmarks
  • Personal dictionary
  • Browsing history
  • Download history

Note: When you refresh Firefox, your old Firefox profile will be copied to your Desktop folder  in a folder named Old Firefox Data.

    Buonasera, scusate, ma l’unico gioco che volevo recuperare: gli scacchi, sono scomparsi. Forse potete spiegare il motivo? Avevo anche intenzione di contribuire con un po’ di € alla vostra ottima iniziativa, ma ho bisogno di sincere garanzie. Conoscete il mio indirizzo di posta, attendo vostre proposte, grazie.
    Cordiali saluti
