As far as I understand it, only your addons and DRM plugin will have problems. Browsing should still be possible.

Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or before Firefox 115.13 ESR), it’s crucial to update to Firefox 128 or 115.13.0esr newer to avoid issues with add-ons, DRM-protected content, and other features. For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.
