Lastpass 4.2.1.21
Test was done with Firefox portable. Please verify someone if you can.
Speedometer is from Mozilla group tests: https://mozilla.github.io/arewefastyet-speedometer/2.0/

With Lastpass enabled: result 24.09 runs/m https://i.imgur.com/26uCgGm.png

With Lastpass disabled: result 47.86 runs/m https://i.imgur.com/pQZ9P1T.png

... and there goes Firefox Quantum!

Bummer...FF Quantum's speed is what made me want to switch to FF.

Reproduced here as well. With LastPass (and a few other addons): 30.37. Disabling only LastPass: 65.67.

Same results on both Firefox 57 and 58b4.

This test loads the page many times as quickly as possible. Lastpass is not noticeably slowing down the browser in regular use. It's probably not slowing down the page 2x, it's just adding a bit to an individual page load, which is not really noticeable in real world usage.

It's best time to quit lastpass.

You posted it here; nothing was deleted: viewtopic.php?f=6&t=282565&p=946615#p946615

That test loads a bunch of websites quickly. It is not a realistic environment. Any performance decrease from LastPass in a real world situation is going to be negligible.

Reinstall the LP addon from Lastpass.com
That cured the slowdown problem I was having.
