Hi, [https://addons.mozilla.org/en-US/firefox/addon/lastpass-password-manager/ LastPass] is a password manager, usually it doesn't include functionality to block websites. You can try to check '''Tools '''('''Alt '''+ '''T''') > '''Add-ons''' > '''Extensions '''for similar add-ons and change the '''Options''' or '''Disable''' it/LastPass. [https://support.mozilla.org/en-US/kb/Using%20extensions%20with%20Firefox Using Extensions] You can also try the [https://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems Reset Firefox] feature via '''Help''' ('''Alt''' + '''H''') > '''Troubleshooting Information'''. This may not help if the site is blocked in an external application like security software on the PC. (To revert to the previous profile you were using, close the new profile (i.e. exit Firefox), start Firefox and choose the '''Default User''' profile. While the [https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles Profile Manager] is open, you can also delete the newly reset profile (the one containing random numbers), or the former profile, as the case may be). If the reset is okay, it would be a good idea to delete the old profile as otherwise it would be left intact with the previous data/cache until deleted.
