Lastpass current version doesn't fully open
There seems to be an issue with Windows 10 64bit - Firefox (66.0.5) and Lastpass where after authenticating through the Lastpass add-on / extension icon, it will not expand to show its normal menu-options, preventing me from using it at all.
I reinstalled both Lastpass and Firefox, and it did for a limited period work fine again. I have no idea what triggered this.
Another annoying thing is that Firefox, seemingly since this current version has been installed, is gobbling up 20% of my CPU for no apparent reason, which is causing my mobo fans to run all the time. I don't know which browser tab is causing it, but when I kill the process, the fan goes back to normal. Seemingly, this is perhaps nothing I've actually opened, and its something being run by on startup.
Other possibly related symptoms are that Youtube audio / video playback is out-of-sync.
This isn't happening with Lastpass on Chrome.

How many tabs are open at the time? Close one tab, then another to see who/what is causing this.
Start Firefox in Safe Mode {web link}
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
