Do you still have access to the old PC? If you were using Sync, normally it would transfer that way, but it sounds like that did not work. Just in case, please check the Extensions button list. See: [[Manage your extensions using the extensions button in the toolbar]]. If Sync did not transfer it to your new installation of Firefox, you may need to install from Nord or the Mozilla Add-ons store. Oh, on their help page at https://support.nordpass.com/hc/en-us/articles/360010298318-Adding-the-NordPass-browser-extension it says "Most recent NordPass Firefox extension version is temporarily unavailable on the Mozilla extension store. We’re working on resolving this issue asap. You can use the desktop app or another browser extension in the meantime." Apparently they'll extend your subscription by 3 months as compensation: https://www.reddit.com/r/NordPass/comments/1ieg8rk/nordpass_extension_for_firefox_still_not_available/ ---- I don't know what was wrong with their October release. Maybe it's not compatible with the current release of the main program?? If you want to download it AT YOUR OWN RISK, you can use the Archive.org Wayback Machine "Download file" link (not the install Firefox button). https://web.archive.org/web/20241209045043/https://addons.mozilla.org/en-US/firefox/addon/nordpass-password-management/ Then you can install using the downloaded file: https://support.mozilla.org/en-US/kb/unable-install-add-ons-extensions-or-themes#w_you-are-asked-to-download-the-add-on-rather-than-installing-it
