Hi maxsros, the Dashlane application manages the extension for Firefox. Does anything in this article help:

If Dashlane doesn't detect that Firefox is installed, hmm, does Windows recognize it as a browser, for example, is Firefox listed as one of the browsers you can make your default browser?

You might need to check with Dashlane support.

Nothing here helps. I'm sure it's Firefox's constant updating is causing my issue. Dashlane was working (with issue) it had been installed for a considerable time. I was instructed to uninstall Dashlane. Now I can't get it to show, manage it from Firefox or get Dashlane's extension management option much less Dashlane's webpages to load. I need a dashlane fix as it is looking to be Firefox's issue now.

Hi Spunky, the way the Options/Enable/Disable/Remove buttons are accessed on the Add-ons page has changed (use the ••• icon), but does Dashlane appear on the Extensions list at all?

When you say you can't load Dashlane pages, does that affect the above support link? What happens when you try to load them?

I managed to get it to install last night after doing a reset (and having to reclaim all my tabs-took 1.5 hours for that. Dashlane finally shows in add ons. The webpages do appear now. I shouldn't of had so much difficulty attending to this. the constant updates from Firefox I'm pretty sure caused this. It's fixed for the moment but, you may still want to check on this. I did get a pop up saying dashlane was corrupt
