Add-ons allow you to add extra features and functionality to Firefox. For fixes and new features, keep your add-ons up to date. Here's how to update your add-ons.

Updating add-ons

1. Click the menu button and choose Add-ons. The Add-ons Manager tab will open.
2. Click the Extensions panel.
3. Click the gear icon in the upper-right area of the Extensions panel.

   

4. Choose one of the options below:

• Check for Updates: Allows you to check for any updates to your add-ons manually. If there is an update available, you have the option to choose to update it now or later.
• View Recent Updates: When you click this option, a Recent Updates panel appears on the left, showing your last updated add-ons.
• Update Add-ons Automatically: If you want to keep your add-ons up to date, select this option to let them update automatically.
• Reset All Add-ons to Update Automatically: If you want to update your add-ons manually, select this option. You can check for an update manually at any time.

Update settings for specific add-ons

You can individually adjust the update method for each extension.

2. Click More to see the details page of a specific extension.
3. Select Default, On or Off for automatic updates.
   If you choose Default or Off, Check for Updates links will also appear on the details page of that extension.

5. Close the Add-ons Manager (about:addons) tab.

Can I update legacy add-ons?

If your add-on is not "Compatible with Firefox 57+", which is labeled as Legacy in the Add-ons Manager tab, you can not update it, starting in Firefox version 57 (will be released in November 2017).

After legacy add-ons have been migrated to WebExtensions by their developers, they will be re-enabled to use and update - see Firefox add-on technology is modernizing.
