Banana I would put it differently. I'm sure you didn't mean it but it sounds
kinda like you are throwing him under a buss (text online doesn't translate
well). dh99136751 just registered today so lets teach.
To clarify Magic Banana's statement I think he means to say we can't give you
any support on this particular last pass add-on because it is non-free not
that we won't help you in general.
My personal recommendation is to especially not trust this add-on with your
passwords for two reasons. Firstly, it is non-free software so no one can
audit it and make sure it is secure or even see what it does. While unlikely
it could easily send all your passwords to the FBI or any number of things.
The second reason is because storing your data on someone else's server is
dangerous. Especially something as important as passwords. As far as I can
tell when you use this you are handing over your passwords to a company
(encrypted or not) whose primary goal is $$ and looking out for you will
always come second. I don't know if you have kept up with the news lately
but there have been a lot of security breaches lately (e.g. sony, US Senate).
You can easily store your passwords on your own computer.
I use a program called Revelation which you can find the package for here
(http://packages.trisquel.info/slaine/revelation). I believe there is also a
free password add-on but I have to check the license for it. I'll get back
to you on that.
