''duplicate of [/questions/1464243] thread''. I have latest version of Firefox for Windows 10 and about 2 weeks ago the Last Pass extension from your website stopped loading correctly. The extension installs in the toolbar, but does not work. It partially loads and then freezes up. I was able to resolve by removing extension and then going to Last Pass's website and downloading their Last Pass 4.0. Your extension is messed up. Tom Weaver
