If the problem persists, do not hesitate to contact our support team by filling this form. If you see an error message for Dashlane in the Add-ons section indicating Dashlane is not compatible with Firefox, please make sure that you not using any Firefox version that's below 38. If this does not help, and if your Dashlane extension in Firefox is permanently greyed-out, you can look at this article on our Help Center. The Dashlane browser extension is the magic behind autofill, typing your passwords, payments, and personal details whenever you need them, across the web. Next, click on Create My Account to finalize your Dashlane account. Enter your email address and add a strong password. As soon as the download finishes, the extension will take you to the Dashlane login page. You should also try to restart your computer. Add the extension to your web browser, and you'll be ready in a few seconds. To begin with, I would recommend to try re-installing the Dashlane extension for Firefox by launching your Dashlane app and going to Extensions → Manage Firefox extension. Could you please start by giving me a little more information about your experience with Dashlane in this browser? Is the extension installed and enabled, but still showing a grey light? If you navigate to the Add-ons → Extensions section, do you see any error message next to the Dashlane extension?
