It is not a major upgrade for Firefox, but it solves some errors that needed man hand to be solved and that also brings a couple of new features for use.
First, the update adds protection against downloads of unwanted software that can affect the security of our terminal. As in the desktop version, a warning if we agree to a potentially dangerous site will appear notifying the risks and we act according to our need.
On the other hand, if we do a long press on the buttons back and forth in the navigation menu, now history will appear previously visited pages for quick access without having to go before unnecessarily.
Regarding bug fixes, now the .jpg images are handled with lower processing power and require less memory, which improves performance and minimal autonomy of the terminal.
Desktop version is more difficult to determine which browser is more powerful, efficient and safe, but we can say that Firefox is one of the best alternatives on Android and contains features that Chrome does not have, such as extensions or Wndowis 10 support, quite and necessary and should be implemented. All changes can be found in the release notes for Firefox 40 on the official website.
