created a firefox account specifically to write this: Lastpass add on sucks.

I've used it for years, telling my friends to use it, but it has consistently sucked for the past few months.
I'm using 1password at work and it is miles ahead in terms of reliability.
Lastpass addon will often fail to autofill, or fail to save a new password when creating an account (it just did right now for my firefox account, I had to create it manually).
Save your time and use another of the many competitors.
