How to update add-ons

Starting in Firefox version 57, only extensions built using WebExtensions APIs will work. Not sure if your add-ons are affected? See Firefox add-on technology is modernizing and these Frequently Asked Questions for details.

Add-ons allow you to add extra features and functionality to Firefox. If you need help installing add-ons, see Find and install add-ons to add features to Firefox.

For fixes and new features, keep your add-ons up to date. Here's how to update your add-ons.

  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 any add-ons have been set to update manually, clicking this option will reset all add-ons to update automatically.

Update settings for specific add-ons

Warning: Turning off automatic updates might make you miss important security updates to your installed add-ons. We recommend that if you don't use an add-on, disable it instead of turning off automatic updates.

You can individually adjust the update method for each extension as follows, when the recommended Update Add-ons Automatically option has been selected:

  1. Go to the Extensions panel.
  2. Click More to see the details page of a specific extension.
  3. Find the Automatic Updates line. (You may need to scroll down the page).
  4. Select Off to set manual updates for that extension.
    • When automatic updates are turned off, a Check for Updates link will appear on the details page of that extension.
  5. Select On or Default to set the extension to update automatically.
  6. If you want, you can go back to the Extensions panel to set up others.
  7. Close the Add-ons Manager (about:addons) tab.

Can I update legacy add-ons?

Warning: Turning off Firefox's update option is not a solution for legacy add-ons. Instead, you should replace your legacy add-ons with add-ons that are compatible with Firefox 57+.

If your add-on is not "Compatible with Firefox 57+", it will be labeled as Legacy in the Add-ons Manager. Legacy extensions will be deactivated when you update to Firefox 57. After legacy add-ons have been migrated to the new WebExtensions standard by their developers, they will be re-enabled. See Firefox add-on technology is modernizing for more information.

Extensions that do not meet Firefox's new add-on technology have been deactivated and moved to the Legacy Extensions panel. If you need the add-on, you can visit the developer's website to see if it will be migrated to the WebExtensions standard. The extension will automatically update when the add-on developer provides a compatible version. You can also follow these instructions to look for a replacement:

  1. Click the menu button Fx57Menu and choose Fx57Addons-icon Add-ons. The Add-ons Manager will open.
  2. Select the Legacy Extensions panel.
  3. Click the Find a Replacement button to the right of the add-on. If a replacement isn't available, the Featured Add-ons page will open, where you can search for a compatible alternative. The Extension Finder utility can also help you find replacement extensions.
