How to check the Mozilla Firefox version?

To check the version of Mozilla Firefox currently installed on your computer, you can follow these steps:

• Open Firefox on your computer.
• Click on the "menu" button (three horizontal lines) in the window's top right corner.
• Click on the "Help" option in the menu that appears.
• In the Help menu, click on the "About Firefox" option.
• A new window showing the current Firefox installed on your computer will appear.

Alternatively, you can type "about: about" (without the quotes) in the address bar of your Firefox browser and press Enter. This will open the Firefox "About" page, where you can find information about various browser aspects, including the version number.
