There was an issue with Firefox 7 that may have caused some or all of your add-ons to be hidden. We have released an update to Firefox that fixes this issue and restores any hidden add-ons. Please update Firefox or download and install the latest version from mozilla.org/firefox.

We know how important add-ons are to you and apologize for the inconvenience.

Note: There is a separate issue where add-ons are disabled (not hidden) after updating Firefox. In that case, you should be able to open the Add-ons manager and see them listed as disabled. For help, see Re-enable add-ons that were disabled when updating Firefox.

If you are unable to update Firefox for some reason, you can restore your add-ons with the simple workaround below.

Install the Add-on Recovery Tool

Warning: This tool only works after you have updated to Firefox 7.

Go to the Add-on Recovery Tool page on addons.mozilla.org
Click the green + Add to Firefox button and this special tool will begin to download.
Click Install Now in the confirmation dialog that comes up.
Once the Add-on Recovery Tool is installed, click the Restart Firefox prompt to complete the process. Firefox will restart and your add-ons will be restored.
