Attempting to install uBlock returns error - says corrupt? I'm adding from the Mozilla extension page. Seems very strange ... what's up with this?

Do you have a recent version of Firefox? A root certificate that was used to verify signed content and add-ons for various Mozilla projects, including Firefox, expired on March 14, 2025. Without updating to Firefox version 128 or higher (or ESR 115.13+ for ESR users), this expiration causes significant issues with add-ons, content signing and DRM-protected media playback.

Please update.

Hello Ty ... thx for the reply. I'm actually trying to add it to LibreWolf, and the Settings extension page links directly to the Firefox extension page. My Firefox is updated, and uBlock installed with no issue. Must be LibreWolf weirdness ... I'll check into that direction for any update.
