Updating Your Browser - Firefox – MW+

Updating Firefox Web Browser

This guide will show you how to manually trigger Firefox to check for updates and install them if they are found.

On your computer, click the menu button

The menu button will be in the top right-hand corner of Firefox; it looks like three horizontal lines on top of each other.
Click the "Settings" menu item

After you've clicked the menu button, the Firefox menu appears; one of the items in it is Settings (note: depending on your version, this may be referred to as "Options" or "Preferences"). Click it!
The Settings screen will now appear.
Scroll down to the Firefox Updates section

Part-way down the Options/Preferences page you'll see the Firefox Updates section.

It looks like this:

Version numbers shown here are examples and will change depending on what is considered the latest version...
Click the Check for updates button

To tell Firefox to check for updates and look for the latest version, click the Check for updates button.
Firefox will check for updates

Firefox will now contact the Mozilla servers and ask if there is a newer version of Firefox that you can update to.

If this step fails, it's probably because there's a problem connecting to the Mozilla servers.

If Firefox finds a newer version of itself, it will download it and prepare itself to be installed.

If it doesn't find a newer version, it will tell you that Firefox is up to date.
Restart Firefox to finish updating Firefox

Once the new version has downloaded and unpacked itself, Firefox will prompt you to restart itself.

When you are ready, you can click this button to finish installing the update - Firefox will close itself and restart with the version it just downloaded. All of your tabs should re-open (except if you had any ones in Private Browsing mode).
Firefox has now been updated

If you reopen the Firefox Updates section in Options, you'll now see the "Firefox is up to date" message!
