When I use the Last Pass plugin for FireFox I get a lot of strange behavior with the plugin.
I start to type something in the search box, and I give the query enough so that it is unique. When I move my mouse over to select or interact with the results, it changes to a default listing.
When I delete it and type again, the results no longer change.
This is very frustrating since I use this plugin for all my site.
Sometimes I have to end up opening the vault in order to get the information I need.
