Been using Lastpass for 10 years or so now. Have never had a problem and has always worked for me. It is one of the first things I install after a browser when I reinstall windows. Has saved me a lot of time and hassle.

Nicely done! Absolutely worth the money! Every now and then, mostly in older versions, FF struggled a little with some laggyness on low performance systems. Still, LastPass has all the bells and whistles you need from a password manager solution. I do recommend it!
