How to Speed Up Mozilla Firefox Browser 2022

Firefox is one of the most popular web browsers on the market. It is used by over 153 million people in 2022 and is one of the most versatile browsers on the market. However, it can be slow to load pages and sometimes takes a long time to start up. To speed up Firefox, you can use the latest tips and tricks below to solve your slow browsing issue.

Why Is My Firefox Browser So Slow?

There could be several reasons for slowing down Firefox, and it takes forever to load the first page. The most common reasons are listed below.

  1. Cache & Cookies: Firefox stores cache and cookies like every browser in the market. But when a couple of old and corrupted cache & cookies are stored in the database, it takes more time to complete loading the full page for functional performance.
  2. Restoring duplicate session files: The Mozilla Firefox Support site indicates that duplicate Session Restore files may slow Firefox down. Restoring tabs or windows left open during a crash is accomplished using session restore files.
  3. Out-of-date Plugins: Updates are frequently made to plugins like Flash, Java, and Privacy Badger. It is possible that they can corrupt the entire Firefox browser if you fail to update them regularly.
