Checking which version of Firefox you are using can be important for deciding whether to update it, but also for looking for solutions to any bugs. If you are connected to the Internet, the program will automatically update itself when you perform this procedure.
Steps
Method 1 of 2: On a Mobile Device
Step 1. Open the Firefox menu
Launch Firefox, then press the key to open the menu. In most cases it is an icon with three horizontal lines or three overlapping points.
Step 2. Tap "Settings" in the drop-down that will open
Step 3. Select "Mozilla" on the left of the screen that opens, then "About Firefox" on the right
In this way, the download of the latest version available will start automatically. If you want to avoid downloading it, turn on Airplane mode first
Step 4. Check the version number
You can find it just under the word "Firefox".
Method 2 of 2: On a Computer
Step 1. Open Firefox
Step 2. Activate the menu bar
It may already be displayed (in that case, you should see various items such as "File", "Edit", etc. at the top). In some versions of Windows or Linux it will be necessary to press alt="Image" or F10 to show it.
Alternatively, you can right-click on the top of the Firefox window and check "Menu bar"
Step 3. Check the Information page
Click Firefox in the menu bar, then select About Firefox. In some cases, the About Firefox option is found on the Help menu.
Opening this window will automatically start the browser update. If you don't want to do this right away, please disconnect your internet connection first
Step 4. Check the installed version under the word “Firefox”
A pop-up window should open with "Firefox" written in the center; the installed version number is just below it, in bold.
Step 5. Start the automatic update
If you are already using the latest version available, you will read the sentence Firefox is up to date. If not, the program will automatically start downloading the latest update. You can check the progress of the process in the same window, under the version number. When the download is complete, the browser will update itself on its next launch.
Step 6. Use alternative methods
If the option in the Help menu doesn't work, you can follow other methods:
- Type about: support in the address bar and press Enter. The "Troubleshooting Information" page should open, where you can read the version number you are using in the section Basic information. Just write about: if you prefer to view a more simplified page.
- If you are using Windows, right-click on the Firefox icon on the desktop. Open the Properties section, check the Link tab and click on Open File Location. Use the right click on the firefox.exe file, open Properties again and then the Details tab. In this menu you will find the installed version.
Advice
- If you are using Windows 7 (or later) you can open the "About Firefox" menu using the keyboard shortcuts: press Alt + A, then I.
- If no other method works, open the command prompt and type firefox -version or firefox -v.
