Then attempting LP add-on from> https://lastpass.com/misc_download2.ph the message : 'The add-on downloaded from this site cannot be installed because it appears to br corrupt'. from this site.

Hi, are you able to install it from the Mozilla Add-ons site?

https://addons.mozilla.org/firefox/addon/lastpass-password-manager/

Sometimes users have problems installing from the site because it redirects to a different server that has "cdn" in the address.

The initial URL for the install button is:

https://addons.mozilla.org/firefox/downloads/file/3724736/lastpass_password_manager-4.65.0.5-an+fx.xpi

That sends a redirect which, at least for me, is this new URL:

https://addons.cdn.mozilla.net/user-media/addons/8542/lastpass_password_manager-4.65.0.5-an+fx.xpi?filehash=sha256%3Afb40999a621a106457b4fb4cb4530468fd3e6a316c1dcfa40ad9834a5eb73750

Your URLs may vary.
