The extension is buggy. It interferes with page loading, specifically it ignores scroll position. Basically, if you've scrolled down a page and click a link, clicking "Back" will NOT remember your scrolled position, requiring you to, obviously, scroll back to where you were. It's incredibly frustrating.

Lastpass has continued to be buggy and unreliable when logging in. It doesn't matter if I create a master password or Lastpass does the app consistently gives errors and reports that it is sending an email to me. It doesn't send any emails. Once life settles down I'm dumping it and finding somethining reliable. I am tired of spending 10-15 minutes every day just to log in.

Very Handy

Real Time Saver

What to give Lastpass 5 stars, but resent stories about breached users passwords, got me to switch to another. Have used it flaless on win10-11 Firefox and on Andrroid, without problems.
"LastPass might be having some kind of credential stuffing incident, with master passwords." look at Twitter.
I have used Lastpass for years.
