With most recent update of Firefox, there is no longer an option for "sites" in the LastPass add on - you have to open your full vault to launch a site or search on the add on instead of clicking with the mouse. This means letting go of the mouse and having to type until you find the site and then either clicking via arrows on the keyboard - which does not highlight the chosen site clearly enough or go back to the mouse to click. These are needless steps and causes user-unfriendly delay. Go back to the previous design.

I love LastPass & Firefox and have used both for many years, but this Extension really SUCKS. LastPass extension SLOWS the browser to a CRAWL. Repeatedly Firefox pops up warnings about this extension slowing the browser. This is a known issue, reported to Lastpass since 2016, 2017, 2018... They don't seem to fix it! So best to avoid this one.

Its a very good addon

In my third year using Premium, just switched to Family.

This is one of the best password managers I've used BUT the Firefox version is lacking behind. LastPass causes Firefox to load incredibly slowly and sometimes doens't respond at all.

Please fix the Firefox issues.

Best password manager ever

It runs smoothly, but the 'password copy' function doesn't work
