Last few updates just broke Firefox for me, will not load tabs and wont even login PLEASE FIX

I'm giving the lastpass extension for Firefox a 3 for now. I have been using it with much success on my MacBook Pro and in Chrome, but I have had to uninstall and reinstall it on Firefox once already, and I cannot save new website login/passwords using the firefox extension. It stalls during the save process and then a pop-up error message comes up saying something like "We are sorry, this is taking longer than expected."

This extension will block all tabs from loading when you open the browser until it has completed it's long convoluted log in process.

The extension in Firefox simply doesnot work: impossible to log on.

LastPass? they let every Last idiot Pass their security ¯\_(ツ)_/¯
