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

This addon causes my entire browser to stop working on a fairly regular basis. Every so often, when I start up Firefox, none of my network requests are sent. All tabs just hang in a loading state, but they are not making any calls in the background.

Removing the LastPass addon and restarting the browser fixes the issue, but I then have to reinstall the addon and re-log in to Lastpass before I can access any of my credentials. This is a very laborious process to have to go through every couple of days.
