Checking if your Dashlane Firefox extension is properly installed
If Dashlane does not seem to work in Firefox, despite working in a different browser, or else if Dashlane stopped working completely, you may need to check your extensions to make sure Dashlane is properly installed.
For Dashlane to work, you should see a Dashlane D in your Firefox toolbar, and it should be green when you are signed in to your Dashlane account.
If the Dashlane icon is orange, you are not logged in.
If there's no icon at all, see the instructions below on how to reinstall your extension, which will usually solve the problem.
First, please first make sure that your extension is active in the add-ons / extensions list of your browser. In Firefox, go to ≡ > Add-ons.
Alternatively, just type this in the address bar to open the Extensions page: about:addons
If the Dashlane extension is already active, please close and reopen Firefox, then disable and reactivate the extension.
If the extension still does not work, or if the extension is simply missing from the toolbar, here is how to re-install the Dashlane extension in Firefox.
How to reinstall your Dashlane extension
First, note that if you are on Linux, Chromebook or if you use our extension in Standalone mode on Windows or macOS, we strongly recommend that you do not uninstall the Dashlane extension from your browser, unless you can confirm that your data is synced properly by logging in to your Dashlane account in the web app on a different device and making sure that all your passwords and notes are there. If you have any doubt, please contact our Support team.
In order to uninstall the extension from Firefox, please go to the Extensions page as shown in the previous section. From there, please click the Remove button below the Dashlane extension and confirm.
After that, open Dashlane and go to the Extensions menu. On macOS, you'll need to go to the Dashlane menu and select Install browser extensions in the menu bar at the top of the screen.
Choose Manage Firefox Extension in the list. This will let you install the extension in Firefox. It will open up Firefox and from here, you can click on Install, Allow and finally Add in order to add the extension to Firefox.
The extension should be up and running now.
Check that Dashlane is working in Firefox
To check that your extension is properly working, please visit any website on which you used to have Dashlane autofill your information. Below we took live.com (for Outlook) as an example.
You should see a Dashlane D icon in the login form.
If you do not see anything in the fields, please check that your Dashlane icon is enabled and active and press CTRL R (Windows) or CMD R (Mac OS X) to refresh the page.
In our example, the Dashlane D will be dark green if you already have an Outlook account, or gray if you do not have one. For more about Dashlane D colors, please refer to this guide.
If the extension is installed and enabled but you still have autofill issues, please refer to this guide.
Problems with your browser extension?
If Firefox says that Dashlane is incompatible but you're using the latest public release of Firefox, don't worry. You just have to update Dashlane!
For Windows
Open Dashlane and select Tools > Check for Updates.
For Mac OS X
Update on Mac OS X by checking for updates in the Mac App Store or by opening Dashlane and selecting Dashlane > Check for updates in the top bar menu.
Running Dashlane in administrator mode (Windows)
It is recommended not to launch either Dashlane or your browser in admin mode. Please refer to the following guide in order to know how to make sure this is not the case for you.
On Windows, do I need to run Dashlane or my browser in Admin mode?
How to customize the Dashlane extension to appear in your Firefox toolbar
If your Firefox toolbar has not been customized to show our Dashlane extension, the latter could be missing from the toolbar although it's properly installed and enabled in the Add-ons section. Our extension should normally appear by default in your Firefox toolbar, however it could indeed be missing if you manually removed it from the toolbar, for instance.
If needed, please follow this little clip from Mozilla to check how to add an extension to your toolbar. Make sure to do that with the Dashlane extension!
If that doesn't help and your extension still doesn't appear in your Firefox toolbar, please refer to this article instead.
