Me iba muy bien. No sé porque Firefox lo deshabilita ahora. Un incordio. Gracias.

It's not LastPass - Firefox disabled the add-on, among others, and won't allow it to be downloaded. Look - Update Regarding Add-ons in Firefox | Mozilla Add-ons Blog https://blog.mozilla.org/addons/2019/05/04/update-regarding-add-ons-in-firefox/ You can login on lastpass.com or move to another browser for now.
