It's very annoying. It pops up everywhere, even when it's not a login and hides the area blow that. I can partly deactivate it in the settings, but the plugin forgets that setting, when I'm not logged in to Dashlane (which is the case most of the time). So I see it all the time, it blocks my normal website usage and I need it in very few cases. I will switch to Keepass again. That was much better. There the worst case is, that is shows the icon, which was never annoying to me.
