To save resources, the very resource-heavy but amazing web-browser Firefox dumps open websites in open tabs from the RAM when you are not using them. When you switch back to it after a long time, it reloads the page. You can prevent this from happening.
- Type about:config in the address bar.
- Just accept the scary warning.
- In the search bar at the top of this page, look for browser.sessionrestore.max_concurrent_tabs.
- Click OK, close Firefox and open it up again.
- The setting is saved, and you will find a bit of an improvement.
Note that you won't find the browser suddenly running really fast. This will affect your performance only when you have loads of tabs open and you have been neglecting some of them for a long time.
