Thunderbird 148.0 boosts mail reliability, accessibility, and security

Thunderbird 148.0 improves accessibility in tree views and lets users file messages directly to Favorites. The update resolves a critical issue where new mail checks could stop after sleep or network outages. Security is strengthened with PKCE for Yahoo, AT&T, and AOL accounts, and NTLM authentication is now available for EWS accounts. Bug fixes cover folder management, message filtering, calendar features, and security vulnerabilities.
