When you start Firefox back up again, it should explore your profile folder, other folders, and the Windows registry to rebuild the list.

I have everything from deleting it and reinstalling it and nothing seems to work.

I am not sure if it started right after I updated to the 64 bit version or not but I did just recently updated the Firefox version.

Once this done, install the Dashlane add-on again and activate in the browser.

In some instances, I had to repeat the process multiple times until it worked.

I also tried removing from the registry and installing fresh and it worked.

The only solution I found is to remove the add-on, uninstall from the Dashlane Dashboard Extensions menu, and restart the computer.

This is definitely an annoying problem and has probably cost Dashlane lots of Premium clients.

This should launch a new window listing various files and folders in Windows Explorer.

Once things settle down, could you check the Add-ons page to confirm that Dashlane is enabled and test whether it works.

Open your current Firefox settings (AKA Firefox profile) folder using either.

In the first table on the page, click the Show Folder button.

Leaving that window open, switch back to Firefox and Exit, either.

Pause while Firefox finishes its cleanup, then rename any of these files that you find.
