So this has been happening to my friend for over a year now and it just happened to me.
You open a new tab and go to a new site and it brings up the p/w for the other site you were just on.
When is this going to be fixed?
Could you try these steps to see if it fixes this issue?
Ok, he did do the steps & he just told me today it didn't work.
I have only had that issues once or twice whereas he's had an issue for at least a year, probably longer.
Could you have them also check that their browser's autofill is not enabled as well? This can cause these issues, here's a guide that shows how to be sure only LastPass Autofill is enabled: https://support.logmeininc.com/lastpass/help/how-do-i-enable-or-disable-my-web-browsers-password-man...
Thanks for giving that a try. If the above steps haven't resolve this issue, so that the team can gather more specific details and hopefully reproduce and resolve this issue, could you submit a bug report following the steps here? https://support.logmeininc.com/lastpass/help/how-do-i-report-a-bug-to-lastpass
