Nothing but problems on Firefox 57 64-bit. Have the setup on three different computers and all three are nothing but frustration. Been spending a lot of time googling fixes that don't end up working. Worked with Lastpass on Firefox flawlessly for several years but the last few updates seem to cause more and more issues. A few of the problems I'm having: Lastpass keeps asking for an authorization code every time I log in despite checking the 30 day trust option. The copy username and password buttons are missing. Lastpass forces Firefox to close on different occasions. I have to click in the search box first to start typing instead of being able to start typing immediately. I use Lastpass on Chrome as well and though it is not as problematic it has its share of issues on that browser as well. I'm not sure what is going on with Lastpass lately but their extensions do not seem to be thoroughly tested.
